This is your magazine, literally One of the things that I enjoy most about my job is the need to generate story ideas. Every year, several times a year, I put my thinking cap on and do my best to come up with topics that I think you will find engaging, interesting and above all else, useful – but by no means is this exercise something that happens in a vacuum.
Warmest wishes for the holiday season As the holidays approach, the entire team here at Mechanical Business would like to take this opportunity to thank you for your continued support, and to wish you a safe and Merry Christmas and a Happy New Year.
One of the reasons I enjoy this task so much is that it affords me the opportunity to research ideas, have discussions in and out of the office, to dig into the products being used on jobsites, and most importantly, to talk to experts, like you, about the science and technology that’s at play in mechanical projects all across this great country of ours.
And while I poll readers and suppliers fairly often for general information, our current issue stands apart as several of the articles stem from specific projects, issues and/or problems that our team has been asked about. From dealing with a boiler that’s short cycling (Eric Riml on page 70) to the jobsite stories that became this issue’s Find the Fix puzzle (check out Jeff House’s quiz on page 86) to Gord Cooke tackling questions raised at this summer’s HRAI conference (page 50) and Bob “Hot Rod” Rohr’s chats with readers during his recent trip through the Canadian Prairies (page 20), this issue has a lot of content that is a direct result of feedback from you, our readers, and for that I am grateful.
Submissions: Copyright in material submitted to the magazine and accepted for publication remains with the author, but Mechanical Business and its licensees may freely reproduce it in print, electronic or other forms. Mechanical Business also reserves the right to edit said submitted materials to suit the editorial needs and mandate of the publication. Notice: Mechanical Business is published for owners, managers and decision makers with mechanical contracting firms and the sector’s supply chain partners in Canada. While every effort is made to ensure the accuracy of the information, Mechanical Business, Content Media Group Inc., its staff, directors, officers and shareholders (‘The Publisher’) assume no liability, obligation or responsibility for advertised claims, for errors and/or omissions, or for the results obtained from the use of this information. Manufacturers’ instructions take precedence over published editorial. The publisher reserves the right to publish a printed correction in a subsequent issue for editorial errors, omissions and oversights. Subscriptions are available for $90 plus taxes in Canada and the U.S. Single copies are $15.00. Outside Canada and the U.S., the rates are $150.00 (annual) and $25.00 (single copy).
The strength of a publication stems from its relationship with its readers, and that relationship should not be a one-way flow of information. Talking with you, whether that’s in person at a tradeshow or other industry event, or receiving phone calls and emails, are welcomed opportunities that help ensure that the stories we present can be of service to you and the projects that you are working on. So, as Hot Rod offers in his column, please consider this an invitation to continue the dialogue. Send us your questions, notes and funny stories. You never know, you might just read about one of your own projects in a future issue of Mechanical Business.
From time to time, Content Media Group Inc. makes subscribers’ names available to reputable companies whose products or services may be of interest to readers. If you would like your name excluded from these mailings, please notify the publisher.

Profile On the road with William Gould
William Gould grew up in the oil heat industry, hopping on the truck with his father from a young age. He still remembers visiting some of his father’s more elderly customers on Christmas Day. “When you get to some of these houses there were elderly people who just wanted to have someone visit them on Christmas,” he said. William would go inside and have a friendly chat while his father worked on the equipment. His friendly nature has served him well as he progressed to being on the tools, and as the owner/operator of Fundy Energy and president
of COHA New Brunswick, but don’t think William’s cheerful demeanor makes him a pushover. He’s been involved in martial arts since he was six years old, and holds black belts in taekwondo and his current discipline, kyokushin, a martial art that involves sparring without protective gear. “It’s literally bone to bone,” he says. “It’s by far the best stress relief after a hard day’s work to spend an hour-and-a-half trying to beat the crap out of someone else,” he laughs. We did our best to keep on his good side as we asked him a few questions.
Q A
How did you get involved in the oil heat industry?
I grew up in the industry. My dad, Jim Gould, used to work at Texaco Canada in the ’70s and ’80s. Dad started up a heating oil company in Fredricton, N.B. I used to work in the office in the summertime, and on truck in the wintertime. It was a real natural transition. I went to university and did a major in business at the University of Fredricton.
Q
What do enjoy most about working in the industry?
A
Working in the industry itself. I love the challenge on a daily basis that comes with running your own business. I love talking with people and seeing customers.

“It never bothers me to ask somebody to do something I’m willing to do myself,” says Gould. “I think I’ve always been that way. If I need to jump on a truck to help a driver out I will.”

How did you get involved with COHA?
It started out when the New Brunswick Chapter was first formed in the early 2000s. I thought it was something different, so I started getting involved. It kind of grew from there. I sat on the board of directors as a representative for COHA National. I was on the executive for five years.
Q A
What hurdles are currently facing the oil heat industry?
One of the biggest hurdles for the industry is the increased competition. In the ’80s you either had oil, electricity or propane. Now you have natural gas, heat pumps, pellets, wood… competition has increased so much. But the biggest hurdle is price regulation. Because we’re regulated for heating oil and the province hasn’t allowed us to have an increase in our margin since 2006, we’re making the same amount of money as 2006, but all our expenses have gone up astronomically.

What’s the best thing about working all over New Brunswick?

I love being able to travel. I don’t have an office. My office is my halfton truck. I’m in St. John today, and tomorrow I’m in Woodstock. It’s interesting to see how different cities change so much. In St. John most people are on hydronic heating, but in Moncton, I would say 95 per cent are forced air oil heat. It’s so interesting to see how, in different pockets, there are such big differences.

A willing pipeline Regardless of where I travel to work, every region has its share of sub-par installations. These jobs are generally brought up to me after class, often with pictures and always with questions of how to make corrections to make the system workable. I’d like to think there will come a time when all installations are appropriately designed and installed, regardless of component selection. Training and networking are the keys to reaching this goal. In addition to the information sharing that goes on in the pages of industry trade magazines like the one you are currently reading, training is widely available online via webinars and on YouTube, as well as at your local wholesaler. And consider my articles in Mechanical Business as an invitation to send in questions. I’ll do my best to provide honest responses and opinions. If I don’t have the answer I know a lot of industry people to call on, from top-notch engineers and number crunchers to some of the industry’s best installers with decades of hands-on experience. The answers you seek are generally knowable, and I’m happy to be a pipeline to knowledge.

he patchwork quilt of landscape, as viewed from the airliner on final approach, hinted that I was about to experience a new and unique training week. I recently flew into Winnipeg on a beautiful clear blue-sky day. This was my first trip to this flat, but beautiful area of Canada. My agenda was a week’s worth of hydronic training that would have me in not only Winnipeg, but Regina and Saskatoon as well. On the ground, I noticed an unusually high number of new and late model pickup trucks scurrying about. That, to me, indicates that contractors are making, or at least spending, money. A quick trip through A&W and I was off to the first training session, at the Sandman Conference Centre. A perfect-sized class was scheduled; just enough people to fill the room, but with enough elbow room to spread out, take notes and enjoy a bite to eat. I enjoy presenting training to groups with a mix of contractors, suppliers and engineers. This type of group provides a good format for the three components of the contracting puzzle to interact, and I encourage a lot of questions in the hopes that the various members of the triad will learn about, and appreciate, each other’s contributions and challenges on a project. It is always interesting to see how a group mingles and responds. I find if the room is mostly competitors from the same general area, not too many questions are asked during the class. In these settings, most often questions will be asked at a break or the end of the training, in more of a one-on-one interaction. That’s okay though. I’ve been in their seat and have, myself, been reluctant to ask a question in a roomful of peers or fellow tradespersons.

The next generation I have been inspired over the past five years of face-toface training in seeing young’uns in attendance – and to me, anyone under 30 is in that category! Diversity in culture as well as gender is inspiring to see, too.
But don’t be afraid to jump in if you haven’t already. Read up. And surf the various industry websites and chat rooms.

Let MB be your portal to success, and please e-mail us with your questions and thoughts.
My recent trip to the Praires assured me that the trend of youth and diversity is alive and well in Canada. Multiple, well-staffed tech schools are cranking out skilled trades-folk, often with job placement. I hear wonderful things about young talent entering our industry. The fact is, our trades – and any hands-on trades – are being noticed and considered as younger generations look for careers.
The
mechanical trio
Contractors are not the only ones who work on projects, especially large or complex projects. For a system to work properly, it needs to be properly engineered, appropriate parts need to be sourced and delivered, and the parts need to be put together properly and efficiently. Engineers, wholesalers and contractors all play a role in a project, and the more we can appreciate each other’s work, the more likely that a project will happen with minimal hitches.
The questions I face The most common questions I get asked are about piping and controlling multiple inputs, and about complex hydronic and solar systems. Blending boilers with solar, heat pumps, and solid fuelled heat sources is very common nowadays, but the systems have to be designed and installed in a way that will avoid system conflicts. Perhaps the second-most-asked question I face has to do with product selection. This is a tough one! There are so many great choices for components. Boilers, circulators and controls keep getting better all the time. Controls with touch screens are very user-friendly, even for the least tech savvy installer, and I’m a fan of them, along with super-efficient circulators with brains, and a plethora of installation products for radiant – you know, all those things that fill the trade mags these days.
The engineers are tasked with designing a system that fits the owner’s needs and provides quiet, efficient comfort. Often it is the engineer who researches and decides which components will be part of the mechanical specification. When presenting training materials, I like to show this group what we have to offer in the way of new and innovative pieces for the puzzles they create. The supplier keeps the shelves stocked with the components to install and maintain systems. They are often springboards for factory training sessions. Progressive and savvy suppliers keep a steady schedule of training queued up for their customers. The contractor/installer is the final link between the design and the collection of components delivered to the jobsite. It is he who puts order to the chaos, to ensure the parts of the puzzle assemble in harmony. It really pays to have all three members of the trio in a comfortable working relationship.

PLUMBING By F re d Br e t z k e
Hang on for dear
pipe support! W
hen my plumbing apprenticeship began, way back in the day – okay, it was 1977 – I was not too concerned about the Ontario plumbing code. As a 17-year-old apprentice, I just imitated my journeyman mentor. Roughing in homes in the rural areas of St. Thomas, Ont., was an experience in humidity, very hot 98-degree sweltering humidity. As a team, my mentor and I would rough in two houses a day. He was the brains, I was the brawn. He would mark out the holes and I would drill them out. He would rough in the main stacks, and I would do the easier kitchen and laundry stack. We used ABS piping. Every pipe had to have the yellow printing turned to the front and all the glue joints had to be wiped clean. Basically, the piping had to be installed quick, clean, to the correct code, and most importantly, the piping had to have proper grade and support and look like hospital piping. It had to look like a piece of art – a “stand back and admire it” kind of thing. It was only light ABS piping, so we used galvanized strapping. I never noticed how much we used, I didn’t know the code, and it always passed. I know one thing though, I never put much strapping on because I figured light piping wouldn’t need it. So I would support it at the ends of each length, about three metres apart. My mentor would always say I messed up somewhere and let me stew about it. I was on a learning curve, but it was early.
My first house A few months after I started my apprenticeship, I was left to rough in my very first house. My mentor made everything look so easy. As such, I had a lot of confidence working alongside of him. Now, left to my own 17-year-old devices – all brawn, little brains, and no code book, and equipped with a hole saw and recip saw – I commenced slapping ABS pipe together. I began gluing ABS fittings together at the wrong angle, desperately trying to twist them to the correct direction when the three-second glue had already partially set. Panic set in. My pipes didn’t seem straight, there was glue smeared everywhere. I cut pipe out and reinstalled them, I was running out of fittings. I’d run to the truck several times getting more galvanized strapping so I could wrap it around the pipe several times and

Going vertical
According to the 2010 NPC, vertical piping is supported at its base and at the floor level of alternate storeys by its rests, each of which can bear the weight of pipe that is between it and the rest above it (Clause 2.3.4.4. 1).
pull the pipe straight. It was getting late in the afternoon, and my boss would soon be arriving. I stood back and looked at the main stack in the basement and it looked like a piece of art alright – an abstract piece of art. Panic set in again, I had to fix it quick. I ran outside to the front yard and grabbed more sticks of three-inch ABS pipe to try and replace the improperly graded pipe. Unfortunately, ABS pipe doesn’t stay very straight lying out in the hot, humid sun. As I tried to replace the spider web of piping, I realized that the new piping was bowed badly from the heat of the sun. After reinstalling it again, it looked worse. Once again, out came the galvanized strapping. This time I strapped it everywhere. I pulled and pushed and tightened that strapping around that pipe so much, it almost looked straight. continues on page 24

When my boss finally showed up, late, he ran downstairs, and looked over at me. There I was, this sweaty, young kid with ABS yellow glue in his hair and all over his clothes, and he just started laughing. “It’s taken you five months to finally figure out how much strapping pipe support to use,” he said. That’s when I realized you can never use enough hangers or strapping. I can’t remember, but I only hope I used enough expansion joints and offsets to overcome the extreme tension that must have been on that poor pipe.
Citing the code According to the 2010 NPC (Table 2.3.4.5.) all ABS piping must be supported every 1.2 metres horizontally, and not the three metres I used to try. Light plastic piping requires shorter distances between hangers, as the hangers are preventing the plastic piping from sagging. Solid metallic pipe can have more horizontal distance or space between the hangers as it is rigid piping. For example, Table 2.3.4.5. shows that copper tube needs to be supported every 2.5 to three metres, depending on the size of the pipe. Regular cast iron pipe is horizontally supported every three metres at, or adjacent to, each hub or joint. The above photo illustrates the mechanical joint piping and supports from a commercial jobsite by Hoover Mechanical. This shows cast iron with mechanical joints that require horizontal hanger spacing of one metre apart. Keep in mind that these are minimum codes. As Rob Purcell from Hoover Mechanical advises, you can never have enough hanger support.

A warning to all The following is an incident report of a recent fatality in the U.S., regarding temporary pipe supports. Alvin Thomas, a 30-year-old contract general foreman was killed in April when a suspended 40-foot long section of 36-inch diameter steel pipe fell and struck him. An excavator was being used to position the pipe to connect it to another section of pipe. The pipe, attached to the excavator by a lifting strap, shifted and fell on him. The pipe was being installed as part of a new system to flow wastewater from flotation tanks back to a new impoundment. According to the incident report, the accident occurred due to contractor managementâ&#x20AC;&#x2122;s failure to identify the risks associated with the task of installing the pipe. The contractor had established policies and procedures; however, management failed to follow them. Additionally, the victim had not received task training before installing the pipe. He was working under a suspended load when the load shifted and fell on him. On the day of the accident, Thomas had conducted a safety meeting with his crew. After that, they went to the work site and started installing pipe. The crew had installed eight sections of pipe without incident, but ran into problems with the ninth section. They were having difficulty connecting it to the adjacent pipe because it began to curve. The crew used sledge hammers, sleever bars, wire rope choker cables, and come-a-longs to help, but they could not connect the two pipes. As such, an excavator was pulled into duty to suspend the pipe. The male end of the pipe being installed had been inserted partially into the bell end of the other pipe. The excavator was then moved to the far end of the pipe and the sling reattached, leaving the spigot end of the pipe unsupported. Thomas went under the spigot end to pry the pipe when it slipped out of the bell end of the adjacent pipe and fell to the ground striking him. Even though this accident occurred in a U.S. mine, it was still a pipe that was improperly supported, and should serve as a warning to all of us who work with pipe on jobsites.
As easy as 2.3.4. ... In the Canadian National Plumbing Code 2.3.4.1. 1, under Capabilty of Support, the code dictates that piping shall be provided with support that is capable of keeping the pipe in alignment and bearing the weight of the pipe and its contents. Itâ&#x20AC;&#x2122;s easy to remember just like 1, 2, 3, 4, itâ&#x20AC;&#x2122;s 2.3.4.5. of the plumbing code, under support for nominal horizontal piping.

The advantages of
inhibited glycols A
s we all know, water is an essential element for all life on this planet. Unfortunately, without the help of inhibited glycol, it doesnâ&#x20AC;&#x2122;t exactly quench the thirsts of HVAC/R systems. Waterâ&#x20AC;&#x2122;s relatively low freezing and boiling points limit its application in HVAC/R systems. In addition, the presence of oxygen has the potential to contribute to metal corrosion, and dissolved solids in water can create system buildups that restrict flow and act as an insulator. So what about other options, such as oil and methanolbased fluids that offer better operating temperature limits? Unfortunately, these fluids can also lead to issues related to corrosion, fouling, seal wear and evaporation, hence the reliance on inhibited glycol.
FLUID options There are a variety of glycol-based heat transfer fluids available in the marketplace, so make sure the one you choose is appropriate for the application. Here are some pointers:
Hydronics When it comes to hydronic applications, propylene-based glycol is often the best choice. Although ethylene glycol is cheaper, it is toxic and has an oil base that may shorten the life of PEX tubing.
HVAC systems For HVAC systems, inhibitors in glycol-based heat transfer fluids provide corrosion protection for the majority of standard metals and alloys, such as steel, cast iron, copper, brass and solder. These inhibitors can be periodically analyzed and replenished to potentially last several years before requiring complete replacement. Glycol-based auto antifreeze, on the other hand, is ideal for fluids touching aluminum parts, and for the high temperatures and agitated environment found in auto engines. It is inhibited with silicates that can gel in HVAC systems where agitation is less pronounced, and where copper and steel are typically used. This reduces heat transfer and can potentially foul or plug the system. More abrasive silicates can also lead to premature pump seal failure. continued on page 30

High-performance FLUIDS HVAC continued from page 28 Ethylene glycol-based fluids are often the best choice for HVAC applications, due to their ability to act as an efficient heat exchange media. Although ethylene glycol is less toxic than the inhibitors in most auto antifreezes and inhibited brines, they should not be used in any applications where they could come into contact with potable water, food or anything else designed for human or animal consumption. Propylene glycol was designed for these applications, and it can be used when local codes require a low-toxicity fluid. Industrial inhibited glycol heat transfer fluids for HVAC/R systems are versatile. Properly inhibited ethylene and propylene glycols can extend service life, provide efficient heat transfer and simplify maintenance, and they are compatible with a variety of process equipment. Some equipment manufacturers recommend industrial inhibited glycols as optimum heat transfer media.
Corrosion protection Corrosive organic acids form within heat transfer fluids as a result of glycols oxidizing when they are exposed to heat and oxygen in the air. Inhibitors act as a buffer for the fluid by stabilizing the pH in the fluid that is reacting with the organic compounds. This buffering is designed to help block acid’s corrosive properties from attaching to metallic components within the system, and to protect the metal’s surface against additional corrosion. Fresh inhibitor can be added to some glycol-based fluids to restore their corrosion protection capabilities, as a fluid’s buffering capacity is weakened by depletion of alkaline reserves.
Running hot and cold The nominal temperature range of aqueous glycol-based heat transfer fluids varies according to the percentage of glycol in the solution and the formulation of the fluid, but a typical range is 60˚F to 250˚F. When a glycol-based fluid is subjected to temperatures that surpass the manufacturer’s specified upper limit, thermal degradation will set in. And when an aqueous glycol-based solution’s temperature falls below the freeze point, ice crystals will start to form, since the water freezes first, making the remaining solution more concentrated. As slush forms, the fluid volume can expand and flow into the system’s expansion tank.

A 35% glycol solution provides adequate burst protection to about -100˚F.
A propylene glycol solution generally becomes too viscous to pump at -25˚F to -30˚F.
Dipotassium phosphate is the inhibitor used in glycol/water systems. The use of sodium molybdate as a glycol system’s primary inhibitor risks sacrificing the longevity of the glycol and potentially damaging the system, creating downtime for repairs and replacement due to its limited buffering capacity.

B y Go r d C o o ke Recommended minimum Many questions have been raised about the recommended minimum glycol concentration of 25 to 30 per cent. For example, if a system only requires freeze protection of 20°F (-7°C), and this can be achieved with 18 to 20 per cent glycol, why should at least 25 per cent be added? There are several reasons for the recommended minimum concentration. The first is corrosion protection. Some glycol-based heat transfer fluids are designed to work in both heating and cooling systems, at a wide range of concentrations. For them to work successfully, the starting fluid must have the right balance of inhibitors in order to maintain proper corrosion protection at various concentrations. The inhibitors are formulated to give optimum performance and fluid lifetime at glycol levels between 25 and 60 per cent. Reducing the glycol concentration below 25 per cent reduces the inhibitor concentration to a level that may not provide adequate corrosion protection for a system. The second reason is stability of the fluid. Both ethylene and propylene glycol break down when exposed to high temperatures. With a higher concentration of fluid, there is also a greater concentration of inhibitor present in the solution. The higher level of inhibitor provides more buffering for any organic acids that may be formed due to glycol degradation. The third reason for using at least 25 per cent glycol in the system concerns the possibility of bacterial growth. With concentrations at or above 20 per cent, both ethylene and propylene glycol inhibit the growth and proliferation of most microbes and fungi. The reduced surface tension in the glycol solution interrupts the cell walls of the bacteria, resulting in an environment that will not support bacterial growth. At very low glycol concentrations, for example, below one per cent, both ethylene and propylene glycol act as a nutrient for bacteria. At these concentrations, bacteria will biodegrade the glycol causing rapid growth of bacterial contamination. At levels above one and below 20 per cent, some bacteria can survive with limited growth, especially at moderate temperatures.

Acronyms
at the compressor
T
here are a number of acronyms used that refer to the various electrical terms for refrigeration compressors, motors, etc. These terms can be confusing and may lead to a misunderstanding of how branch circuits and associated electrical components are sized. Brushing up on the meanings of these terms can be helpful, regardless of how much field experience we have. Here’s an overview of some of the terms that can be handy to know on a project.
Thermally Protected Many refrigeration and air conditioning compressors are designated as “Thermally Protected.” This is an official designation that is part of a bi-national standard between CSA C22.2 NO 140.2 and UL984. A compressor with this designation will have a predetermined maximum motor winding temperature limit, such as 100°C or 212°F, which is determined, to some extent, by the maximum temperature rating of the motor winding insulation material. In this case, one or more PTC or NTC temperature sensors are used. For example, some compressors use a group of PTC sensors wired in series and connected to an electronic module. As the temperature of the motor varies, the resistance also varies. Any one of the sensors alone can cause the module to trip. Compressors that are thermally protected will be marked accordingly on their nameplate. When a motor experiences a higher than normal load, imbalanced phase voltages, a missing phase, etc., the winding temperature increases as a consequence of the rising amperage. The thermal protection arrangement works to ensure that the branch circuit that feeds the compressor cannot overheat and lead to unsafe conditions.
overheat and fail when it is subject to adverse operating conditions. For example, motor insulation that is subject to windings at 210°F will not have the longevity of a motor that operates at 180°F. Short-cycling results in a motor’s repeated exposure to the LRA, along with the heat that results. Even though the protector will take the motor off line at some point, it will still be subject to high temperatures. So even with a thermally protected compressor, a condition such as repeated single phasing will cause permanent damage to a motor. It is recommended to install phase protection that monitors the incoming voltage to the system along with the voltage that is supplied by the contactor. continued on page 34
Interestingly, we often think of a thermally protected compressor as one where the motor is protected against overheating. Although the winding temperature is not generally permitted to exceed a certain value, a motor can still
MCC
The maximum continuous current value of a compressor is determined by a procedure established by UL. This is an electrical test to determine the maximum load that the motor can carry without overloading. The MCC provides the basic value from which the RLA is calculated.

REFRIGERATION continued from page 32
RLA The RLA or rated load amperage is a calculated value defined by UL that establishes a minimum branch circuit amperage requirement. According to UL, the RLA is calculated as MCC divided by 1.56. Prior to the 1.56 rule, a more conservative 1.40 factor was used. Most manufacturers recommend using the 1.56 divisor for the branch circuit wiring and 1.40 for the contactor. When sizing contactors and related components, the LRA must also be considered. A contactor may be adequately sized in terms of the RLA but not LRA.
Should the branch circuit always be selected based on the RLA? No. The MCC divided by 1.56 is the minimum branch circuit amperage. It is important to keep in mind that semi-hermetic compressors can generally operate within a wide range of operating conditions. The RLA is actually less than the MOA that is used in other countries. Therefore, we must remember that when compressors are operated at conditions that result in a current that falls between the RLA and MOA, that we choose this higher current for the sizing of the branch circuit.
Why do many compressors not show an RLA or FLA value?
As an example, compressors are commonly used in heat recovery applications where both the suction and discharge pressures are within the compressor operating envelope but at relatively high values. In this case, sizing the circuit for RLA may prove to be inadequate.

In the past, the FLA or full load amperage was commonly listed on the nameplate of semi-hermetic compressors. As the name implies, FLA only occurs when the motor is fully loaded. FLA could be considered to be similar to the MOA used in Europe where it is used when sizing branch circuits. During the early 1970â&#x20AC;&#x2122;s UL replaced FLA with RLA. In North America, compressor manufacturers are not required to list an RLA on the nameplate. Instead this is left up to the manufacturer of the equipment. This gives the manufacturer the flexibility to reduce the amperage of their equipment to a value that can be as low as the RLA if the application permits, and if the equipment is designed in such a way as to not to exceed this amperage.

MOA
On the same Page
The MOA is the maximum operating amps of a compressor. This is not an official term used by the electrical codes in North America, however it does provide valuable information. For example, as the name implies, the MOA represents the maximum amperage for a particular compressor and voltage. Compressors must not be applied in applications that will enable the MOA to be exceeded.
LRA The LRA, or locked rotor amperage, indicates the peak amperage that the compressor draws just before the motor starts to rotate. This is the same amperage that would exist when trying to start a compressor that has seized. The LRA is generally in the range of fourand-a-half to seven times the normal operating amperage. Compressor manufacturers are required to state the LRA on the nameplate. This information is useful when determining the maximum value for fuses and breakers. According to the Canadian Electrical Code (CEC), the maximum value for these components should not exceed 50 per cent of the LRA.
Fortunately, the Canadian Electrical Code (CEC), National Electric Code, UL and CSA requirements are very much harmonized when it comes to hermetic and semi-hermetic compressors. This makes it somewhat easier to understand the contents of the applicable code and its requirements. It is important to be familiar with terms, along with their meanings. Having a good understanding of these various terms and how they are applied in the electrical codes will provide you with the information to help you ensure that branch circuits are adequately sized and protected from overload.
Follow your local This article is intended only to provide some general guidance and clarification of national code requirements. Always be sure to follow the latest versions of the relevant national and local codes that apply to your equipment and its installed location. Remember, local codes can override national code requirements.

Assessing and using feedback Not everyone’s ideas can be represented or incorporated in a logo. You don’t want it to become unfocused and convoluted. In the end, it must always be a strategic visual brand. When evaluating audience responses, the strongest and most prevailing opinions should be considered, weighed against strategic goals for the brand and evaluated accordingly. One-offs should not be discounted though – if your community loves a specific logo, but external audiences and businesses rank it amongst the lowest, careful evaluation is required. Make the necessary tweaks yourself if you can, or this might be the best time to engage a professional designer. The heavy lifting is done, so the fee should be reasonable... simply ask the designer to finalize the logo based on the key findings from your research. At the same time, small professional adjustments will take the logo from great to spectacular.

You have invested hours of time and substantial resources in the development of an appealing and relevant logo, so care must be taken to protect its integrity. It should not be used improperly, inconsistently and without permission. This fragmentation will undermine the strength of your brand, and how current and potential customers see and understand your organization. It is always a good idea to create a logo guideline document to help ensure that you are always presenting a consistent and identifiable message.
The Guide
That’s right. HRAI doesn’t accept just any company to its ranks. Only those with properly trained and licensed technicians.

Protecting your logo
A logo guideline should be a document that is long enough to contain detailed instructions, but not so long that it is confusing or ignored. Three to five pages should be plenty, and along with showing samples and illustrations to help with dimensional requirements, be sure to address the following in the guide: • Preferred positioning/location (ie: always top right with nothing above your logo) with application examples on key items such as uniforms, stationery or vehicles, to name just a few; • Protected space rules around the logo (be sure to give it breathing room); • Size restrictions (no smaller than 1”, for example); • Logo typefaces and complementary fonts that work well with it; • Pantone colours with CMYK and RGB formulas, and a complementary colour palette; and • Co-branding guidelines to address partnerships or collaborations with other brands.

COVER STORY By Andrew Snook
An amazing opportunity Jody’s friend, and Thank A Soldier blogger, Dave Murphy didn’t have to do much talking to convince Jody to participate in the ultimate race, Amazing Race Canada, where Jody and his brother Cory finished in second place. “One day Dave calls me and says, ‘I’m going to apply to Amazing Race Canada, do you want to apply with me?’” Jody explains over lunch at a café in Ottawa’s Byward Market. “Dave put in the application and called me two or three weeks later, and says ‘Hey, we need to do a video. They like us.’” At the last minute, his friend and potential race partner Dave was unable to get the time off work and had to pull out of their application. Fortunately, his brother Cory had already expressed interest in competing in the show. “When Dave couldn’t do it, Cory already had his bags packed, ready to go.” Since he is planning on retiring from the military in the near future, and is interested in a career in media, Jody figured appearing on the most popular show in Canada would be a good way to get his name out. In addition to his desire to secure a reality TV deal and continue to build up the Never Quit Foundation, Jody hopes to capitalize on his fame from Amazing Race Canada by writing a book about his life story, and possibly embark on a media career. “I am retiring from the military soon and I have two little girls and a house to pay for, so I have to be successful in something, and I have no doubt I will be.”

f there’s one word that best describes Jody Mitic, it’s perseverance. While serving his country as a sniper in Afghanistan, Jody lost his legs below the knees after stepping on a land mine. But that traumatic incident hasn’t stopped him from pushing himself towards new challenges. From running and motorcycle riding to charity fundraising, reality TV, radio and writing, Jody’s goals and ambitions are vast, and he is meeting them head on.
42
The Amazing Race Canada will return for a second season in 2014.
“I lost my leg once, riding. My I was adjusting the leg
A healthy challenge The most positive experience Jody got out of competing on Amazing Race Canada was remembering the importance of challenging himself whenever possible. “I kind of kicked my ass a bit,” he says. “I was becoming kind of complacent in my life. There are things that I wasn’t trying and putting on my priority list. Walking that beam in B.C. and repelling down the building were a lot of fun. Running around the desert, cutting across the Yukon, I just remembered how much fun I have when I challenge myself.”
A wild ride Jody says he is always learning something new when it comes to riding his motorcycle, but one particular experience that stands out is navigating his bike with only one leg. “I lost my leg once, riding,” he laughs. “My right leg fell off while shifting gears, I was adjusting the leg on the peg and it fell off.” Jody says he had a half-second before it came loose where he could feel the leg detaching. When it came loose he said he didn’t panic. He said the experience was similar to being in combat and race car driving. “Time slows down for me,” he says. “I’m one of those lucky people, I can think very clearly.” When the leg fell off he slowed the bike down and was able to safely bring it to a complete stop. “Luckily the leg that stayed on was the side the kickstand was on,” he said. Although Jody was able to remain calm through the experience, it took the motorist behind him by surprise. “I looked behind me and there was a guy white-knuckling his steering wheel 30 metres behind me in his Honda,” he says. “His eyes looked like dinner plates. I flipped up my visor and said, ‘Hey,’ looking at my leg, ‘why don’t you bring that over here.’” The motorist not only ran out of his vehicle to retrieve his leg, he also presented it to Jody in the correct manner for it to be reattached. “It’s one of those things that happened that I tell people about and they laugh, but imagine the story that guy tells,” he says.
An inspirational figure Since participating in Amazing Race Canada, Jody says he’s recognized almost everywhere he goes. A point echoed during our interview when he was approached by a couple of fans eager to say hello. Jody chatted with them for a few minutes before continuing our discussion. “I love it,” he says. “Everybody is so supportive of Cory and I, so I appreciate that a lot. Overall, it’s been very positive.” A lot of people have approached Jody and told him that he has inspired them to improve their own lives. It’s a role that has taken him time to respect. “Now I understand it, but before it was something I almost rejected,” he says. “When people would say something like, ‘I’m very motivated by you’ or ‘I look up to you’ I would diffuse it and say, ‘Why? There are other guys that are wounded too’. It slowly dawned on me that I was being a bit of a jerk by telling them they were silly… it’s a role I take seriously now. It makes me rethink the things I’m doing. I have two kids now, and those are people you really want looking up to you, and for the right reasons.”
Never quit Jody is passionate about helping Canada’s brave men and women who have been injured in service to their country. To assist them he started the Never Quit Foundation, an organization run by Jody and two of his friends who work out of Windsor, Ont. and Petawawa, Ont. The foundation is dedicated to assisting people in adaptive living situations by offering them advice based on real world experience. The foundation is also raising funds for the purpose of sending wounded soldiers, police officers and other emergency services workers and amputee children to special events. He came up with the idea while working at the Soldier On program, a joint initiative between the Canadian Paralympic Committee and the Department of National Defence. “Soldier On is meant to get you back into sports partnered with the Paralympics, but what about the kids that like skateboarding?” Jody asks. “Even though I was 30 when I got hurt, I still liked alternative breakdancing, skydiving and car racing. I thought, wouldn’t it be fun if I could do stuff like go to UFC events and bring injured soldiers. “The biggest thing that we’re doing is building a mentoring and peer support network.” Jody says going to the Paralympics with Soldier On provided a positive experience for many people, himself included, but it was after the events at a pub over a pint when people would do a lot of healing. “Now you’re a group of people in a similar circumstance, so now you can say, ‘Hey, you’ve had a fake leg for two years more than me, you ever had this problem?” he says. “We’re trying to build a group that will support each other in the long run.”

Vents freeze too
Preventive measures
Ever get a call about vents being frozen or blocked? It’s not all that common, but isn’t unheard of. Overhanging trees can drop leaves and needles that find their way into vent pipes, and snow on a roof can also block the way and cause problems, but a jetter can help clear the airway to get the water in the plumbing system flowing properly again.
I like talking about tools, and matching the right tool to the task at hand, but when it comes to frozen pipes, the best tool is often prevention. Rather than waiting for a problem to develop, adding insulation or heat tape to vulnerable pipe systems can keep a problem from developing. Sometimes just placing a lamp with an incandescent bulb under a sink during a cold snap can provide enough heat to prevent supply lines from freezing up. In some cases, leaving the water flowing at a slight dribble could also help keep the line from developing an ice blockage. If a blockage has developed, however, it helps to keep rule number 1 in mind: Do no harm. So check for cracks in the pipe and be ready to deal with a flood, and to do a quick repair job, if the ice has broken through the pipe wall.

T
he cold weather months are upon us, and while that tends to have heating professionals running from jobsite to jobsite, the plumbers among you know the plight of pipes once the snow begins to fall, and that heating systems are not the only mechanical systems with emergency calls happening out there. Poorly insulated water lines that have been installed on exterior walls, often under closed-in kitchen cabinets or in crawl spaces, are susceptible to freezing – as are lines that have not been buried deep enough to stay below the frost line. And frost lines can change from yearto-year, meaning that a cold snap that dips below the norm can have customers on the phone placing emergency calls to the closest plumber who can fix the problem. Thankfully there’s a wide array of tools that can help get the water flowing again, on both the delivery and the drainage sides of the system.

<<<The inside job
It’s always a nice touch to end a drain clearing job with a quick check with a camera. Providing your customer with a video of a clean line after you are done will show them that you’ve done the job right. Just keep in mind that camera equipment can get caught in a blockage or broken pipe, so don’t push it if you are trying to show the customer the before and after. They know there’s a blockage – they would not have called if water was flowing properly. The “after” video is the more important of the two.
Having a blast When it comes to clearing ice in a waste or vent line, the right tool will make short work of the task, but what to use? Some cable rooters will have accessories that look like they might be up for the job, and some might be able to handle a small blockage, but using an average rooter and cutter combination will likely end up with only a partial path being cleared, along with a fair bit of frustration, and in cases of an extreme ice blockage, possibly some damaged tools.
Finding buried “treasure”
The hard part with trying to clear ice with a cutter is that as the blockage starts to break apart slush can form and the blockage can form again and again, not unlike what happens with a grease blockage.
Pipes running underground, such as drainage lines running to a septic tank, can be susceptible to freezing if they were not buried deep enough, especially if the pipe has bowed or sunk after it was buried.
The best tool to clear an ice blockage in a waste or vent line is a water jet. A 3,000 psi, four gallon per minute jet can thaw a four-inch line at a foot per minute, even when using cold water. And cold water is often advisable to use, since hot water may cause thermal shock to the pipes and joints in the piping system, putting undue stress and possibly causing just as much damage as the original ice blockage.
Some homeowners will run hot water through the lines to keep them from freezing up, but that can be costly on utility bills, and as that water cools, it too becomes a freezing hazard. For pipes that are damaged or bowed, sometimes it is a necessity to dig them up and re-lay the pipes. But it isn’t always easy to know where to dig. That’s where a pipe locating unit can be a great investment.
Water supply lines that have been blocked by ice can be made fluid again by using a pipe thawing machine. These units use low voltage power with a high current to react with the metal pipe and provide enough heat to melt the ice. These types of machines will not work on plastic, and should not be used on non-metal pipes.
The cold will not affect the frequency and the signal’s ability to get through ice, snow or solid earth, but it can affect the battery life of the locator. So keep the batteries warm, or have spares on hand, and follow the pipe locating practices outlined in the instruction book that came with your pipe locator. (You did keep the manual, right?)
The use of blow torches or welding torches is not advisable as they present a significant fire risk.
Working the jetter>>> Clogged lines should be jetted from the downstream side. This will allow water and debris to flow more easily out of the line. When thawing ice, this becomes even more important since the ice will start to flow downhill. If you attempt to clear the blockage from the upstream side, the water you add to the line could freeze before the clog is cleared, and this could cause a backup of water, flooding the house. When picking a nozzle to use with your jetting equipment, look for one with one or more forward jets, in addition to the rear jets. This will help with the melting of the ice block, as well as the removal of debris and cleaning of the pipe walls. Hot water is not necessary to clear ice. Cold water will do the job without risking damage to the jetter’s pump, since most pumps don’t like water above 160 degrees (71°C).

Combo A heating systems
fter much research, industry consultation and development, Natural Resources Canada is now mandating that any combination heating system installed in an Energy Star labelled home after March 2014 will need to be tested to the new CAN/CSA-P.9-11.
Revising performance test methods
When I built my R-2000 home in 1992 the idea of using one really efficient, condensing water heater to provide both domestic hot water and hot water for an air handler to heat my house seemed really compelling. Shortly after it was installed it was pointed out to me, and the industry, that the water heater condensed nicely during a call for domestic hot water but not when the air handler was pulling hot water for heating my home. The challenge with combination systems is that, traditionally, we used two different technologies to satisfy two different loads. Domestic hot water heating starts with relatively cool entering water and large peak system load, but relatively short duration during hot water draws. Space heating loads are characterized by relatively warm entering air temperatures with relatively small instantaneous thermal loads over a relatively longer duration.
Example of Loads: Entering temperature
Delivery temperature
Flow
BTU requirement
Hot water for a 10 min. shower
6-8˚C (42-46˚F)
40-42˚C (105–108˚F)
9.5 L/m (2.5 GPM)
75,000 BTUH for 10 minutes
Space heating for an Energy Star home on a design day
20-22˚C (68-72˚F)
50-55˚C (120-130˚F)
400 L/s (800 CFM)
45,000 BTUH each hour
The essence of a truly energy efficient combination system is that the heat exchange process must get to condensing mode not only in domestic hot water heating mode, but also in space heating mode. The challenge is that the return water temperature from the space heating coils will generally be much warmer than the city water inlet temperature. This is particularly difficult in “part load” conditions or mild days, when the space heating needs are very low. Experience has shown over the past 20 years, highest efficiency is only achieved when efficient water heaters and air handlers are well matched and the operating system intelligently controls both the water heater and air handler together. Successful control strategies are able to vary the water temperature and flow to the air handler to ensure the water heater condenses all, or at least most, of the time.
Waiting for our results The first results from P.9-11 testing are expected in the next few months, just in time for the March 2014 deadline. More importantly, tested products will provide better clarity and consistency in the reporting of overall performance of combination technology. continued on page 52

High TPF ratings
factor
A very helpful report was written by consultant Peter Edwards for Natural Resources Canada that describes the CSA P.9 testing and strategies to produce high performance results. The report outlines a new energy performance metric called thermal performance factor (TPF). This metric combines ratings for space heating and water heating performance, and takes a load-weighted average of the two to generate a performance rating.
The best performing combination systems will always start with a condensing water heater that has a thermal or combustion efficiency of at least 90 per cent, but the report written by consultant Peter Edwards goes much further and describes in detail the components and features that are needed to achieve high TPF ratings.
The standard assumes that the daily domestic water heating load is the same as the water heating load that is currently used to determine the energy factor (EF) ratings for residential gas and oil fired water heaters in North America. In P.9 it is referred to as the water heating performance factor (WHPF). The space heating component is perhaps more interesting. The P.9 standard recognizes that heating systems will operate under part-load conditions most of the time, and thus combination systems are tested under loads that equate to 100, 40, and 15 per cent of their space heating capacities. The results are combined to provide an overall composite space heating efficiency (CSHE) that weights the part-load conditions most heavily, to reflect more closely to the actual operational cycle for most homes. The related formula and corresponding graphic representation, taken from P.9 is shown in Figure 1. Note how the graph and formula show that a system is evaluated assuming it is operating at 40 per cent of heating capacity, 60 per cent of the time.
Figure 1: Space Heating Load-Duration Curve
Operating mode
The ability to recognize quickly whether the demand draw is for space heating or domestic hot water so that the return water temperatures can be kept low enough to maximize condensing.
Condensing performance
The ability to condense over a wide range of water flows and fuel inputs. This typically will require modulating controls for the burners with a high turndown ratio.
Modulation of water temperatures
The ability to vary the outlet water temperatures over a wide range of flow rates.
Variable flow water pump
The ability to vary water flow rates.
ECM fan motor
The ability to vary airflow across the air handler heat exchange coil.
Hot water coil
Properly sized coils to extract as much heat as possible from the water to enable low return water temperatures without compromising air discharge temperatures or pressure drop over the coil.
Controls
Controls that enable airflows to modulate in conjunction with water flows and water temperatures such that lower airflows are used to extract residual heat from the coil.
The above list of the most important attributes of a high performance combination system leads to the following conclusions: • Combination system testing requires interaction of components that have traditionally been totally separate. • Manufacturers of individual components will find it difficult to achieve high TPFs without co-operation from other manufacturers. • Manufacturers of water heating technology intended for combination systems will either want to develop their own air handler, or closely partner with another manufacturer to provide an air handler that optimizes control and performance.
(Adapted from CSA P.9-11)
For comparison purposes, a combination system with a TPF of 0.90 can be assumed to have an overall energy performance roughly equal to the combined performance of a 95 per cent AFUE gas furnace and a water heater with an energy factor of 0.67.
• Storage tank water heaters, even those that are able to operate in a condensing mode, will be challenged to achieve high TPF performance without controls that can identify and adjust combustion characteristics to ensure condensing over a wide range of water flows and return temperatures. • The overall installed performance of a specific combination system will depend on the mix of space versus domestic hot water heating loads.

ACCESSORIES
CONCENTRIC VENT KITS
VENT SCREENS
System 636 Concentric Vent Kits (CVK), are available in a variety of lengths and come in 2", 3" and 4" diameters. These “pipe-in-pipe” kits allow for both exhaust and intake pipes to penetrate the roof or side wall through only one hole. The concentric vent kits are now certified with mechanically fastened rain caps. When installed with the included stainless steel screw/nut, the rain cap can be easily removed for cleaning or maintenance. Vent screens and round face plates for side wall terminations are also available.
IPEX also offers 2", 3", 4", 6" and 8" vent screens (plastic or stainless steel) to prevent debris and rodents from entering and plugging the venting system. These non-certified vent screens can be friction fit into any IPEX termination kit.
•
Screw/bolt assembly for mechanically fastening the cap yet allowing future removal for cleaning or maintenance
•
Socket end to the vent pipe portion of the cap which allows attachment of additional pipe and fittings to extend the vent pipe further away from the CVK if required
•
The 45º wye component of our CVK is more compact than other available models and thus structurally stronger and more resistant to cracking due to bending stresses during installation
The Testing Plug and Bushing Kit allows an inline access point for flue monitoring using fully certified System 636 components. The kit is available in PVC and CPVC, and consists of two components – a 2 x 1/2 reducer bushing (Spig x FPT) and a removable 1/2" MPT plug. •
May be installed in new installations or added to existing lines when monitoring is required.
•
Bushing must be inserted in a 2" fitting socket.
•
May be used on vent lines in any diameter. Certified for use only on IPEX System 636 flue gas vent lines.
•

ROUND FACE PLATES
WALL TERMINATION KITS For a traditional vent style, IPEX’s PVC Wall Termination Vent Kits are available in convenient 2", 2-1/2" and 3" sizes. These PVC kits require only two small wall penetrations for intake and exhaust. Kits include a white finishing plate with a self sealing foam back that can be screwed to the exterior wall. Vent screens not included.
LOW PROFILE TERMINATION KITS (PVC) These kits offer a lower profile alternative to the typical two pipe side wall termination kit. They include integrally molded vent screens, and the design neatly disguises both the intake and exhaust. Each kit is molded with a ULC S636 certified beige PVC compound.

TESTING PLUG & BUSHING KIT
These round face plates are the perfect accessory for single wall penetrations like the Concentric Vent Kits (note the face plate must be one nominal size larger than the nominal size of the CV Kit). The plates may also be helpful in instances where two pipes are too far apart to use a two hole termination kit. The face plates help cover unsightly bore holes created during the pipe installation. They are available in both white and gray to match the certified vent pipe, and each plate includes a self sealing foam back.
RECTANGULAR 2 HOLE FACE PLATES These white PVC finishing plates are available in 3 sizes and include a self sealing foam back. They are perfect for side wall applications that require terminations that the Side Wall Kits cannot accommodate. The face plates can be used with PVC or CPVC venting as they do not contact the flue gas, and can be painted to suit the application.

SYSTEM 636 FLUE GAS VENTING ®
FLAME SPREAD & SMOKE DEVELOPMENT RATINGS
ULC S636 STANDARD – PLASTIC VENT PIPE FOR GAS FIRED APPLIANCE
Both System 636 PVC and CPVC pipe exhibit a Flame Spread Rating of 10, while CPVC pipe has the added feature of a Smoke Developed Classification of 50. These properties are listed as per the ULC S102.2 test standard.
SYSTEM 636 PVC MAY BE USED IN: •
Noncombustible buildings, as detailed in clause 3.1.5.16 of the National Building Code (NBC)
IPEX recommends the use of certified thermoplastics for flue gas venting and offers a fully certified system in both PVC and CPVC, System 636. Reasons for the implementation of the ULC S636 standard
•
Appliance standards do not address the flue gas venting system and its acceptability for the application.
•
Prior to 2007, uncertified flue gas piping failures forced the adoption and enforcement of a national standard for flue gas venting.
•
Beyond the testing involved in the certification process the standard goes an important step further to ensure safety. ULC S636 stipulates that no mixing of components from different manufactures can occur in the venting system. This would include pipe, fittings, cements and terminations.
•
The no mixing clause ensures quality and compatibility.
•
Several appliance manufactures specify certain approved materials for venting in their installation manuals. The ULC S636 standard ensures that these materials meet the testing and specifications, creating a safer flue gas venting system.
•
ULC S636 has been enforced nationwide in Canada since 2007.
SYSTEM 636 CPVC MAY BE USED IN: •
Noncombustible buildings, as detailed in clause 3.1.5.16 of the National Building Code (NBC)
•
Air plenums, as per NBC article 3.6.4.3.(1)
•
Buildings deemed to be high-rise, as per NBC article 3.2.6.
Enforcing the ULC S636 Standard will ensure: • Pipe, fittings, and cements compatibility • Proper use of materials and product for the application • Long life of the venting system • Single source liability • Single source product support

Finding the right people John C., Montreal, Que.
“Roger, where do I find good people in this industry?”

Don’t divide… guide Contractors often complain about the generational divide but that’s not new. I’m sure our parents talked about us that way. I know mine did. There are lots of great potential employees out there. We are finding plenty of bright, young people with great attitudes and a thirst for learning. They have little, if any experience. But that’s our job. We have to train them to the ways we do business.
hen it comes to questions I get asked, this is one of the most frequent ones. Unfortunately, we are not alone in our industry. Surveys of employers in all industries say that finding good employees is at or near the top of their biggest business challenges. The biggest problem for contractors seems to be with finding field technicians. Unfortunately there is no people tree. There is no one out there growing and training people for us. We can’t just go and pluck someone from the tree on demand when we need him or her. But the good news is there are lots of good people out there. The key is you have to train them, and that means you are going to have to spend time and money. Quality people you can count on are more than worth the investment. Most of us are in business for the long haul and people development is a long-term solution. Contractors often balk at the expense of training, asking, “What if I spend all this money training them and they then up and leave me?” I usually answer with: “What if you don’t and they stay?” Federal and provincial governments recognize the need for training and have had very good incentive programs to hire and train apprentices in place for a number of years. Here in Ontario, the combined subsidies provide tax credits for up to 40 per cent of wages paid, up to a
maximum of $12,000 per apprentice per year. This keeps the wage competitive and provides money for training. These programs have allowed our company to bring in a lot of young talent. The future for people in our industry has never been brighter. There is a large pool of talented young people supported by good government programs to hire and train them. Those who take advantage of it will set themselves up for success for a long time.
Assessing the fit Each business has a unique culture. We always talk about fit. But what is it? Well, it varies from company to company, but we need to define it and learn how to recognize it in others if we want to make good hiring decisions. At our company we use a system called Predictive Index (PI). This gives us a profile of an individual that we can compare to benchmark profiles of our best people to look for matches. PI quantifies it.
It is only one tool but it increases our odds of getting someone who will fit in with our company. We recruit good people almost exclusively on the internet. For those looking for low-tech solutions, we also put a sandwich board out front. And we typically get at least 100 applicants for every job. We also work with co-op programs at high schools, colleges and universities. We offer internships and work with the local government to place new Canadians looking to get work experience. There is no cost to most of these programs.

The straight story on
PUMP CURVES R
esidential circulators are interesting things. You stick ’em in a system, wire ’em up, turn ’em on, and they run. That’s the first of the two criteria most people look at when it comes to circulators: Does it run? It does? Good! The second: Is anyone calling me to complain that they don’t have heat? No? Ha! Even better … must be the right pump then. But as we know there are all kinds of circulators out there. There are circulators with steep curves and there are circs with flat curves. There are circulators with multiple curves, and there are circs with variable curves. Isn’t there just one pump that’ll do everything? Come to think of it – isn’t that why we have three-speed circulators? Why do we need to have all these different circulators? The short answers: No … no … and because different circulators, with different curves, have different applications.
But there’s one small problem. We don’t install circulators in theory. We install them in houses. And we connect them to systems. Some jobs, such of those with zone valves, require flat curve (high flow, low head) circulators. Other jobs, such as panel radiator and thermostatic radiator valve installations, require the higher head, lower flow performance of a steep curve circulator (and your most common three-speed circulators have steep curves). But what if you try sticking the proverbial square peg into a round hole?
I love a good mystery. And this whodunit has Sherlock Holmes, Columbo, and Shaggy, Scoobie and the Mystery Machine, all rolled into one. The mystery in question involved a boiler change out. The new 80,000 BTUH boiler serves five zone valves. Along with the new boiler, a new expansion tank, pressure reducing valve and air scoop were also installed. The installer, told that a three-speed circulator is the only circulator he’d ever need as it can do everything, installed exactly that, a shiny, new, three-speed beauty. The old boiler had an old three-piece circulator. The system was nice and quiet, and it heated just fine. Its only crime was that it was old and, therefore, not as efficient as a newer one would be. The new system was much more efficient and provided the heat needed, but there was one problem – it wasn’t quiet at all. The zone valves banged like crazy! continued on page 56
M e c h a n i c a l
I’m sure we’ve all been told at some point that three-speed circulators are the only ones you’ll ever need. After all, it has three speeds, so it must be versatile. Keep it on the truck for service and you’ll never go wrong. Well, that may be correct in theory. You may find that the three very similar pump performance curves of a typical three-speed circulator might technically cover most flow and head requirements you’re bound to encounter out there.

Three-speed to the rescue?
B u s i n e s s
1 2 . 1 3
For instance, what if you were to install one of those high-head, lowflow, steep-curve three-speed circs in a system with zone valves? Well, if the performance curve of the speed you selected covered the flow and head requirements of the job, it would certainly work. No one would be yelling at you about being cold. No problem, right? Job done, let’s move on … hold up a sec partner … “working” doesn’t mean working right.

“Come Watson, the game is afoot!” Any good detective starts solving a mystery by asking questions. After all, zone valves don’t bang just because they feel like it. Something changed. So, let’s start asking:
• • •
Do all five zone valves bang all the time? If all five are calling and one closes, do they bang then? Does the banging occur when only one or two zones are calling, and then one closes?
With sound detective work, we learn the banging only happens when one or two zones are calling. When all five zones are calling there’s no banging. “Like zoinks Scoob, a clue!” Let’s examine the evidence more closely. Everything’s new, including the circulator. The old threepiece circulator that was quiet and working was replaced with a new three-speed circulator. When the new three-speed model made noise, the installer was told to swap it out for another brand of threespeed instead. Of course, nothing changed. The system still banged – on all three speeds. As Scoobie-Doo might say, “Ruh-roh!” The solution, as it is with most mysteries, is in the details. In this case, it has to do with pump curves.
The Evolution of High Efficiency Condensing Boilers • Innovative Design • Engineering Elegance • Efficient Performance
To the charts! Here are the pump curve charts for the Taco 110 (the original three-piece that was changed out for three-speed pump), as well as the Taco 0015 and the Grundfos 15-58, both being three-speed pumps.
Notice anything? The 110 is what we call a “flat-curve” pump. It’s a high-flow, low-head circulator, perfect for zone valve applications. The 0015 and 15-58 are so-called “steep-curve” pumps. They have lower flow, but higher head pressure. These are great for radiant floor heating, and are well-suited to be system pumps for panel radiator and thermostatic radiator valve jobs. The only substantive change in the system in our mystery was in the style of circulator.
Tune in next time…
So, now that you know the difference in the style of circulators from our mystery, it is time for you to put your thinking cap on. What’s making these zone valves bang? And what are some of the options for making it go away? Yep – it’s a mystery alright. What are your thoughts? I’m eager to share mine, and to offer a firm foundation for solving it … in the very next issue of Mechanical Business.

Feeling the pressure Pressure switches operate off of negative pressure created by the inducer motor. Although there are a few manufacturers of universal pressure switches, it can be very difficult to keep even the right universal on your truck. There are other ways around a faulty pressure switch that can get your customers up and running for a short period, but because they are the proving part for such a crucial piece of the furnace it would always be best to replace this part with an OEM part.
Igniter replacement projects There are a lot of universal igniters, and it is possible to cover a large number of furnace models by just carrying one or two of these universal parts on your truck, making them a crucial part to carry at this time of year. The igniter is the most common item to go on existing furnaces. Replacements can last for years, but some old-style igniters were as regular as clockwork, garnering a replacement once a year. The new universals may require the use of a new mounting plate, and there may be some wiring changes, but if the customer gets to turn the heat back on, it can easily be worth it for them – and for you.
The $1 tip
True HVAC professionals know their reputation is made with every sale. Which is why they choose to sell Armstrong Air.®
Flame sensors are usually field repairable by cleaning them with either steel wool (be gentle) or with an American $1 bill. That dollar bill is how I was taught, and it’s how I still do it. Once you clean them, be sure to order a new one. These again are OEM type items and should be stocked at your local wholesaler.
Part or parcel? HVAC professionals take a lot of pride in the work they do, and the equipment they install. They choose Armstrong Air because they know our standards are as high as their own. With smart designs like MHT™ Technology in the summer and EHX™ Technology in the winter, we have thoughtfully engineered comfort solutions that can delight every customer, every time. If you're ready to make the choice to sell something better, get started at www.armstrongair.com/become-a-dealer.asp
Blower motors come in all shapes and sizes and powers and efficiencies. There are your standard aftermarket replacements and high-end aftermarket motors that can change a standard single-speed motor to a constant torque ECM motor. If these parts fail, communicate with your customer and see if they are just out to replace parts or if this may be a good time to upgrade the furnace.

Residential sprinklers
A safety-first selling proposition Moving quickly Demand for residential sprinkler systems is increasing as fires spread far more quickly than in the past, says Sean Pearce, national marketing manager for the Canadian Automatic Sprinkler Association (CASA) in Markham. “Twenty-five years ago it would take 20 minutes for a flashover to occur. That’s the point where material is heated to burning temperatures. Today the content in homes has greater potential to kill because materials are far more combustible, so flashover can take place in as little as three minutes. Sprinklers can mitigate that substantially.” Anyone doubting the value only need to watch a controlled burn demonstration, says Ingrid McCallum, sales and marketing manager for Townwood Homes Inc. in Concord, Ont. “You have to see a live burn demonstration to understand how quickly these fires spread. Once they start, the toxic smoke is astounding. Sprinkler systems can transform what might have been a life changing event into just an inconvenience.”
T
he residential sprinkler installation market received a big boost in Ontario when Vaughan recently became the first municipality in the province to mandate sprinkler systems in all new low-rise home builds. Townwood Homes will be the first builder to test the waters, so to speak, having committed to installing fire sprinklers in its newest 136-unit townhome and semi-detached home development, Mackenzie Ridge Terraces, which is currently in development. This could be one of the most significant turning points for fire sprinkler installation work since they were mandated for condominiums in April of 2010, says Marco Scorsia at Star Fire Systems in Concord, Ont. “The condo market has been very good to us since then.” Having been in the installation business for years, Scorsia says sprinkler systems are becoming an important selling feature for builders. “Home buyers see it as having their own firefighter on the job 24 hours a day, seven days a week. After all, we see sprinklers in industrial buildings and offices, and even in the parking lots of buildings. Why don’t we have them in our homes where we and our children live and sleep?” continued on page 66

Residential sprinklers continued from page 64 More coverage Leading sprinkler head manufacturers throughout North America have invested a lot in developing lower K-factor heads that operate on lower pressure and volumes. “K-factors are getting lower and lower every year, while still offering great coverage,” explains CASA’s Sean Pearce. A single low-K factor residential head today can cover an area of around 144 sq. ft. “Ten years ago you may have needed two or three to cover that,” Pearce says.
Designed for residential use The Townwood Homes houses will be outfitted with CPVC fire sprinkler systems on all three floors, with the exception of attic spaces and garages, which will have a heat detector installed that connects to each home’s smoke alarm system.
Interest is growing
Each residential unit will have 13 to 18 sprinklers, with concealed pendants on the main floor and interior wallmounted sprinklers on the second floor. This will help avoid vapour barrier penetration and the potential for freezing of pipes. The incoming water supply uses a one-inch double check valve assembly with a flow switch that is connected to an external bell. All components to the double check valve transition point are copper and the system is designed to prevent possible cross-contamination of the water supply. Sprinkler installer Marco Scorsia estimates the installations will take up to a week for each townhome. An added incentive for sprinklers in residential homes is the fact that newer systems are not only more aesthetically appealing, but also remarkably efficient, says CASA’s Sean Pearce. The market is also becoming more competitive, which means better pricing and easier maintenance. Not to mention that fact that today’s designs are much more suited for residential needs.
Anyone interested in getting into the installation business should take note that sprinkler fitters need to be certified in order to perform installations in many jurisdictions today. “Sprinklers are actually classified as a life safety system,” explains Sean Pearce. “Even though you’re moving water, it’s not considered to be plumbing. So ensuring you have the proper training and certification to install is critical.” A little investment in training could go a long way given the growing concern for safety in the home. Many municipalities and insurance providers have shown interest in sprinklers as a way to reduce the damages and risks associated with fires, so residential sprinkler systems may, in time, become as common as smoke detectors.
“Newer systems can go into walls or ceilings, and be painted to match the décor. Maintenance is almost nothing with options like NFPa 13D passive purge models that test the system each time water is used, such as when a toilet is flushed. That takes away the burden of the municipality coming in to do backflow testing. Code changes have made all those kinds of things available for residential systems.”
“It’s like airbags in cars. Lee Iacocca decided to use them and everyone in the world followed suit,” Pearce says. “Sprinkler systems are starting to get the same awareness as an important safety need in people’s lives.”
DID YOU KNOW? • The National Fire Protection Association (NFPA) reports there is an 80 per cent reduction in both fire deaths and fire-related injuries when sprinklers are present.
• Automatic sprinklers also serve to reduce risks faced by firefighters when fighting fires in buildings constructed from lightweight engineered wood framing systems
• Compared to an equivalent non-sprinklered home, damage from fire can be reduced by 95 per cent when sprinklers are in use.
• Not only do fire sprinklers reduce fire and water damage, they also combat the release of toxic combustion products that result from fires.
• Today’s home contents burn hotter, faster and are more toxic – this combination can lead to conditions becoming fatal within two minutes of a smoke detector sounding.

Eric Riml is a certified hydronic designer working in Calgary, Alta. He can be reached at feedback@hotwaterheating.info.
T
hese types of systems are common, and no, they aren’t the most efficient design, but they are cheaper to install, and have less expensive parts that can fail. That said, hydronic systems aren’t cheap to start with, so many homeowners are indignant that their “premium” system still has inefficiencies inherent in the design.
Coping with cycling A reader writes:
I’m working on an oil-fired burner system that runs a mixture of glycol for radiator heating. The system has five zones and a separate water storage tank. The problem I have is this: With all zone valves operated by programmable thermostats, they are turning down at 10 p.m. So at this point, there’s nothing that’s driving a valve to open. However, the burner continues to cut in every 15 minutes, and fires up for two or three minutes, and then shuts off again. It seems to me that it’s just cutting in to keep the glycol lines at a certain temperature, in anticipation of a zone valve opening. The system also has an infinite loop which runs to an external garage. I’m not sure what to do, but it seems completely inefficient for a boiler to be cutting in and burning 20 per cent of the time needlessly.
I’m going to assume that your oil-fired boiler is Is there a way to regulate the burner the same way that we regulate the zone valves using a a cast iron boiler, meaning that it needs to be programmable thermostat? Or is this normal to behave this way? kept hot to meet any imminent needs because it has a large volume of water inside it, and it takes a long time to heat up. Furthermore, it cannot be run at low temperatures, or else the acidic condensate created will destroy the boiler’s heat exchanger. So the boiler is firing in anticipation of a heating load. You have a few options with this type of system, but none of them are as simple as installing or upgrading thermostats.
1
Option 1: Outdoor reset The first and possibly easiest fix is to install an indoor-outdoor, or outdoor reset, control that comes with setback and auto-differential features. These controls can adjust temperatures for setback situations and adjust the boiler water target temperature for actual outdoor conditions. The automatic differential feature extends the length of time between boiler firings. I suspect that the boiler has a fixed 20°F differential, probably operating between 180°F and 160°F. As such, the boiler will fire until it reaches 180°F and then cool to 160°F before firing again, regardless of load. The auto-differential could extend the range to 40°F or more, meaning that the boiler will cycle less which, in turn, wears its components less. The outdoor reset on the control will also ensure that the boiler fires to a minimum temperature (140°F) to burn off the acidic condensate, but not require the boiler to fire to its full 180°F when that temperature isn’t required because it’s not that cold outside. I suggest this as your “go to” solution because I’ve personally seen significant savings from installing indoor-outdoor controls.
Deadhead avoidance The infinite loop, also called a “wild loop,” exists so that the boiler’s main pump does not deadhead (i.e. have nowhere to pump its water and burn itself out) when no zone valves are open. continues on page 72

Option 2: Wire up the controls My second level of fix depends largely on the wiring setup for your thermostats, zone valves and DHW tank aqua-stat. If the zone valves and/or thermostat wiring can be accessed such that you could allow them to call the boiler when needed, then the boiler could be made to fire only when there was a demand from one of the thermostats or hot water tank. This change would prevent the boiler from firing at all when there is no call for heat, but the downside is that when a call for heat does occur, the boiler’s response will be slow. If this fix were implemented, you should probably also put a zone valve and thermostat on the garage loop, and install a pressure bypass on the boiler loop. The main problem with this fix is that during the spring and fall seasons, when the heating load is low, the boiler could cycle a lot. A boiler control can be installed to ensure that the boiler is allowed to reach an operating temperature high enough to burn off condensate that forms on the heat exchanger before shutting off.
3
Option 3: Adding a buffer The third option for a fix, which doesn’t require any thermostat re-wiring, is to install an insulated storage tank to act as a buffer between the boiler and the zones. Note that the DHW tank is not fed by the storage tank. In this configuration, you would require at least a setpoint control on the storage tank, preferably with auto differential, or set to 30°F differential. This design provides the boiler with a large mass of water to heat so that in times of low demand for space heating, the boiler will fire very infrequently, and will have a nice long run time when it does fire, which is good for burner efficiency and wear.

I advocate contractors to suggest that homeowners stock replacement parts for their heating systems. With more and more heating products coming into the market, it is nearly impossible for a heating contractor to have the right parts in his truck. Worse, if the parts are not in stock at the wholesaler’s, and they have to be ordered in, a client’s heating system might be down for several days. Thus, homeowners should probably stock some minimal parts, including:
• • • • • •
A circulation pump, or parts for that pump, if the pump is one that isn’t commonly stocked;
An ignitor/thermopile for the boiler and/or hot water tank (if hot water tank is direct-fired); A high-limit switch/sensor;
A replacement relay, if any relays exist in the system; A replacement zone valve or actuator; and Replacement sensor(s).
These parts should cost less than $500. I know, I know, your customer is going to scream, “Five hundred bucks?!!!” But ask them if they would pay $500 to get their heating system up and running immediately, rather than having to live without heat or hot water for three days. I think we all know the answer to that, especially around the holidays. And there is still the possibility that something will break that’s not on the list above, but these items will handle most of the more common repairs, and they are also “maintenance parts,” so they are likely to be used at some point, if not for an emergency fix. Unlike throw-away consumer electronics, boilers remain a product that can be repaired; and being mechanical, they will eventually fail, regardless of how reliable the brand is. B u s i n e s s

DUCTLESS
for retrofits
T
he uncertainty surrounding the global economy has not kept the Canadian construction industry idling. The pace may not be record setting, but the industry has been humming along, and many home and business owners are taking the opportunity to retrofit their existing spaces. When it comes to the systems that will heat and cool these redeveloped or expanded buildings, many are looking beyond traditional HVAC options. Getting inverted A key contributor to ductless system energy efficiency has been the introduction of “inverter” technology. Though this technology has been in use for more than a decade in Eastern and European countries, it’s a relatively new player in the HVAC sector in Canada. The inverter converts AC power to DC and uses pulse-width modulation to produce variable frequency AC current, modulating the speed of the motor to match the heating or cooling needs of the space being conditioned.
Whether for additions, whole-home cooling or to improve interior comfort for spaces lacking sufficient HVAC, ductless mini-split systems are gaining a foothold for retrofit applications. The remodeling boom, increasing energy costs and conceptual changes about how to heat and cool interior spaces are the key ingredients that have brought ductless solutions into the mix. The notion that every room in a home or business must be conditioned to the same temperature – all the time – is a concept that Canadians are challenging more and more, especially as they learn about the benefits of zoned systems.
Augmenting existing systems A little over a year ago, one of the contractors we work with, Dave Yates, installed a one-ton ductless system in a residence that had a traditional central HVAC system. When the family built the home, six years earlier, they were not looking to use the space above the garage, but a change of mind resulted in an urge to finish the space. This led to a mini-split heat pump installation as an HVAC system add-on. Use of the mini-split would avoid time-consuming, disruptive and expensive central HVAC alterations, and the family could quickly have a system that would condition the interior space, exactly where and when they most wanted it.
was streaming steadily through the outside condensate line,” said Yates. “But when the homeowners checked on us toward the end of the job, they couldn’t believe the system was running – both the indoor fan coil and outside condensing unit operate so quietly that you have to strain to hear them.” While individual specifications will vary by manufacturer and model, the inverter-based ductless system installed in this home can operate in heating mode down to -15°F, and as low as 0°F in cooling mode. This reduces the need for supplemental heating on most winter days. The unit also offers a dry mode setting, for summertime dehumidification – without altering room temperatures by more than one degree Fahrenheit.
The mini-split was installed by Yates and two technicians in three hours. “The room was noticeably cooler within minutes, and water

The family also opted for a wireless remote controller, to make programming for comfort levels a relatively easy process. continues on page 80
High-performance HVAC continued from page 78
DUCTLESS FOR COMMERCIAL Ductless systems are also well-suited for light commercial applications. Multi-zone systems with just one variable-speed outdoor condensing unit can accommodate several indoor units. Each indoor unit can be turned on or off at will and each will communicate with the outdoor unit separately. The outdoor unit’s logic module can alter the delivery of refrigerant as needed to serve each of the air handler’s needs. As a result, each indoor unit’s remote control can be set at any level. One of the latest advancements to take the stage in the commercial mini-split market is the introduction of variable refrigerant flow, or “VRF” technology. With VRF, heat is transferred directly to and from interior spaces by circulating refrigerant between a remote condensing unit and interior evaporators. Wall-mounted ductless or fan coil type compact ducted units with evaporators are located in or near occupied spaces. Multiple evaporators can be connected to the system allowing for optimal temperature control zoning. Just as with traditional ductless systems, heat is transferred via the refrigerant to an outdoor condensing unit. These systems can serve a wide range of applications including nursing homes, restaurants, office buildings, schools and churches. The system minimizes the refrigerant path compared to a multizone mini-split by connecting multiple indoor units to a common liquid and suction line. The shorter refrigerant Variable-speed VS. path allows for greater system on-off technology performance from the same amount of compressor work. Space temperature control in VRF systems is achieved by modulating the flow of refrigerant to each evaporator using an (EEV) electronic expansion valve. Fan speeds are also variable. The variability of “inverter” operation and zone temperature control leads to improved comfort and energy savings.
The reality in HVAC is that on-off technology is rapidly losing its appeal, and that can be seen in new furnace technologies, pumps and fans – basically any HVAC equipment that pushes fluids or air around, and mini-splits are part of this emerging trend. With ductless mini-splits, the indoor units use equipment that systematically changes or modulates to match heat loss and gain. Microprocessor control intelligently guides the function of variable speed system output, the difference, if the system were a car, between punching the gas or feathering it. A logic module continuously monitors indoor and outdoor temperatures. Sensors feed this information to the control board. If anything goes wrong, a fault code indicates what’s going on with the equipment.

Know your site and build it right
L
ike many wholesalers, if you’ve worked with us in the past on your projects, you know that we pride ourselves in developing a proper contractor-wholesaler relationship. This allows us to help each other stay profitable while helping customers meet the heating and cooling needs of their facilities. So, what does your wholesaler need to know when it comes to helping you size and design a refrigeration system? Well, in the commercial and industrial refrigeration sector we start with some of the fundamentals – and this is information that is both compulsory and helpful. Standard information gathering should include voltage and phasing information for the conditioned space in question; saturated suction temperature (SST), ambient conditions, desired refrigerant, and box temperature. The choice between an air cooled unit or water cooled one; the option of using an indoor or outdoor condensing unit; or choosing to remote the compressor from the condenser, will all be factors that are helpful at the planning stage. From an energy management standpoint, there are plenty of selling features that you can offer your end user that allow for a more efficient operation. Electronic expansion valves (EEVs) for tighter superheat control, specialty controllers that allow for defrost by sublimation, and digital or VRF compressors can all help on the energy savings front. If the system is using an automated or specialty control system, pressure transducers are typically recommended for precise pressure measurement and remote monitoring. You should ask your refrigeration sales representative for all your options. New technology is making its way into the refrigeration world, and it brings with it limitless opportunities to have precise control, while avoiding unnecessary service calls.
Working the walk-in
In a new cooler or freezer box, get the dimensions of your conditioned space, no matter the size. Having the length, width and height are what’s important, so measure accurately so system design matches your application. Information about the wall and ceiling panels, doors, and their corresponding thicknesses is useful as well, as is knowledge of the insulation material (polystyrene, urethane, etc.). If the space doesn’t have proper insulated panels, be sure to notate the wall material. In some larger refrigerated warehouse spaces, the ceiling and outer walls can encounter a solar load, which may not always be taken into consideration when providing site information, but this affects load factors that could influence product selection and system design.
Luc Seguin (left) and Kevin Gill of The Master Group L.P. were the key wholesale point people on the 500-ton refrigeration retrofit at the Ontario Food Terminal in Toronto. They credit the hard work and teamwork of the manufacturer, wholesaler and contractor partners for the success of the project.
What are you refrigerating? Product information is imperative to know, so beginning with the entering temperature of the products will help us determine load values. The pull-down duration requirement, if any, from the entering temperature to the final holding temperature is next on the list. Pull-down will be calculated on a per pound of product basis. This will have a dramatic effect on the capacity with which to remove the heat from your products. Refrigeration loads can vary based on entering temperature, product density, product material, and the pull-down duration. continued on page 84

Watch the pH Acidity can be a factor that some technicians don’t take into account. For example, if your end user is storing fruit and vegetables, the citric acid being emitted from these products may erode evaporator fins. This can cause insufficient heat transfer, which can cause a surplus of liquid refrigerant to leave the evaporator. Special protective coatings are available from different manufacturers to help prevent this kind of erosion.
MATCH THE EVAPorators If replacing a condensing unit only, always size according to the evaporators you already have in place. Location and positioning will also play a key role if a system has multiple evaporators in larger spaces. You should consult with your sales rep if you are unsure about the most strategic way of equally circulating air throughout the space.

CASE STUDY: NO SMALL UNDERTAKING The Ontario Food Terminal (OFT) is one of the busiest produce hubs in the province, and with 80,000 square feet (7,400 m2) of cold storage, it’s no small undertaking. The Master Group L.P. recently teamed up with Cimco Refrigeration in Toronto to tackle this huge project, designing over 500 tons of cooling to upgrade the facility. The new system includes 16 condensing units and 84 evaporators, as well as temperature monitoring and defrost controls from KE2 Therm Solutions. With the assistance of Keeprite Refrigeration, the companies were able to meet the deadline for delivery and build the roster of equipment and materials in approximately three months. This is the first of several shipments due to arrive at OFT, and the systems should show significant operational cost savings over a conventional system.

So much for simple… You are the successful bidder on what should be a simple commercial retrofit. Your job is to take out one large inefficient boiler and drop in a pair of small stainless steel condensing modulating high efficiency boilers. The boiler fittings are 1” coming off the manifolds; the main boiler piping is 3”; and the existing system pump was recently replaced, so you decide to not replace it. First you cut in two 3” x 2” x 3” Ts as close as you can, so the boilers are now the secondary load injecting heat into the system. And you’ve incorporated outdoor reset, for the most building system efficiency you can provide. But there are problems. 1) Once filled, cleaned, filled, cleaned, filled and purged, you start the boilers, but it’s not long before they lock out on a low flow condition. What is going on? A) There is still air in the system. B) The boiler circulators may be air locked. C) The bullhead Ts in the piping are restricting flow. D) You piped the boilers with the same size pipe as the fitting provided by the boiler manufacturer. 2) Your heating designer comes to the jobsite and points out that the near boiler piping is too small to carry the 38 gpm of total flow. You decide to change the boiler piping. What size would you change the piping to, assume you want to have at least a 20°F delta T? A) 1-1/2” B) 2” C) 3” D) The 1” would have been fine if the boiler delta T was 40°F. 3) You change the piping to the correct size, remove the bullhead Ts and then pipe the boilers as reverse return, as per the manufacturer’s installation manual. Flow is now right; the boilers start up and very quickly run up to high fire. Instead of satisfying the load quickly, however, the boilers modulate down to low and the delta T gets to 5°F, at which point the boilers continue to run at the minimum firing rate. What is going on? A) There is still a problem with the flow in the piping. B) The system pump must not be working. C) You assume it is a boiler or software issue and call the manufacturer to tell him “his” boiler has a problem. D) The supply pipe is dumping hot water directly ahead of the return pipe, so since the return water is already hot, the boiler cycles down to low and cycles off when the delta T gets too low.

4) After fixing the piping again, you fire up the boilers. Everything seems to work fine initially, but after 10 to 15 minutes the boiler water set point starts to rise on the reset curve. A few minutes later, the boilers shut down as set point is reached. What now? A) You must have that air in the system problem, again. B) You reprogram the outdoor reset curve again and soon everything is running – until it shuts down again 10 minutes later. C) You go outside and check the outdoor sensor only to notice it is located between the exhaust and the fresh air intake. That’s okay, though. You are on the north wall, so it should be good. D) The boilers fire up and soon the hot exhaust plume is surrounding the outdoor sensor. A few minutes later, the boilers shut down because the sensor is too warm.

IS
infrared right for your customer? I
was discussing the application of infrared radiant heat with another trade professional recently when he said something like, “The most important consideration for an infrared heating application is the heat load. Having an accurate heat-loss calculation is the foundation.”
of administrative or production work happens in relatively small areas. Beyond spot heating, IR can also be applied with great results to provide partial building heat – say for areas such as an assembly line or office section located in an open area of a warehouse.
Well, that’s close, but not exactly step number one. A solid heat load calc is important. It is a key piece of the foundation, but it’s not the first and most important consideration. There’s one part of the foundation that’s even more fundamental or essential to the infrared (IR) equation, and that is: Is the application suitable for IR heat?
Generally, IR isn’t best suited for the heating of entire facilities. To provide relatively uniform heat for large commercial spaces, forced air, hydro-air or in-floor radiant heat are far better and much more efficient choices since thermal efficiencies of IR equipment are normally about 70 per cent, while forced air units and condensing boilers can have thermal efficiencies of 90-plus per cent. Meeting the building heat loss with IR would require a 20-plus per cent fuel premium, which just doesn’t make sense.
As a rule of thumb, IR is ideal for commercial spot heating needs within large, open facilities where small groups of people gather for assembly or factory work, for machining, or in areas where some type

Designing with IR Let’s say that you’ve determined infrared is well suited to your application. For the sake of providing an example, let’s say that midwinter conditions in a machine shop become uncomfortably cool. Let’s also say that the central heating system is pushed beyond its limit. There are a dozen key workstations, or “pods,” with several employees doing tasks at each pod. Rather than attempting to provide additional heat for the entire space (large air volume, with high ceiling), wouldn’t it make sense to provide spot heating for the 12 pods? Once it’s seen that IR is a good fit, the heat load calculation is next on the list. Though we won’t be concerned with warming an enclosed space, we’ll at least need to determine that the IR systems chosen provide sufficient output to warm the workstations below. Next is IR heater selection, though placement of the units also factors into this. Remember that IR relies on clear sight lines to be effective, so there can be no obstructions between the IR unit and the worker. Another key consideration is the clearance to combustibles.
Care must be taken to ensure that the units have adequate clearance around them so that combustible materials will not ignite or be damaged. Don’t forget to consider such variables as:
• Are vehicles parked below the heater? • Are sprinkler heads near the unit? (They’re not compatible!) • Will combustible materials be stored nearby? For our spot heating needs, we’ve already determined that the chief need is to provide warmth for small teams of employees who remain throughout the day in relatively small areas, and that IR heat is not intended to provide significant warmth to the larger surrounding area. For spot heating a very limited area, such as a desk or computer station near a loading dock, high intensity heaters are the best choice. It’s preferable to use two or more heaters for heating people to ensure both the front and back sides are comfortable. If it is impractical to use multiple heaters, it’s usually advisable to use one heater of the next higher model at an increased mounting height. Heater ratings can be determined based on the available mounting height. continued on page 90
Why Use Infrared? • Operational energy savings. The use of infrared may result in significant energy cost reductions for spot heating applications. By design, conventional warm air heating systems must heat the air, but air is not the best heat transfer medium. Only after a large volume of air is warmed is heat transferred to people within the space. Infrared offers direct delivery.

• Infrared installations may actually use lower thermostat settings as the radiant heat reaches workers directly. • Without a need for fans, infrared systems generally use less electricity. • Since IR does not use fans, uncomfortable drafts, blown dust and allergens, and fan or blower noise are minimized. • Temperature recovery is quick if cold air is introduced from open doors or windows.

Tool Tips
Types of heaters
The Transformer in the Tool Box
There are two basic types of infrared heaters, highintensity and low-intensity.
High Intensity Typically, these systems come equipped with a ceramic tile burner for maximum heat transfer, often housed in a metal frame. The flame burns on the outer surface of the tile(s) with the infrared energy efficiently directed by a reflector mounted on the metal frame. Source temperatures can range from 1,800°F to 2,200°F. The units are often certified for indoor use only and operate unvented. A minimum positive air displacement of four cubic feet per minute per 1,000 BTUH input for natural gas, or five cubic feet per minute per 1,000 BTUH input for propane gas, is required for proper ventilation.
Low Intensity Low-intensity IR units are made up of a burner box, a metal heat exchanger tube, and a polished reflector that focuses infrared energy. The burner is mounted at one end of the tube and exhaust gases are vented out the other end. Tube systems are available in either straight or U-tube configurations. Source temperatures near the burner end of tube systems can reach 1,200°F. Vented units are typically available as pressurized type systems which provide a power exhauster mounted at the same end as the burner to force the products of combustion through the tube. Units can be used for indoor or outdoor applications.
Check your height Infrared heat spread and Height throw increases as the mounting height is increased. S pread Width It is important to select 5’ units with specifications that work well for the installation height requirements. S pread Width = (Height – 5ft) x 2 Mounting a unit higher than recommended can result in complaints of low heat output. Mounting a unit too low can result in complaints of too much heat. While the coverage has changed, the infrared output has remained constant, resulting in an increase or decrease in the intensity of the infrared energy over the given area. And keep in mind that high intensity units generally have to be mounted higher than low intensity units. Understanding temperature distribution and resulting effects on comfort heating plays an important role in determining the effectiveness of IR applications.

ne of the most versatile tool additions that has emerged over the past few years is the multi-tool. These can be equipped with different end pieces that cut, drive, saw and fasten, all with one motor – so the cost of ownership is much less than buying separate tools. The accessory heads may vary depending on the trade, but with an impact driver head, drywall saw, straight blade for cutting door jambs, drill, jigsaw, sanding head, and reciprocating saw head, the tool will be up for pretty much anything that might be found on a jobsite. A plumber might opt for reciprocating saw, drill and impact driver heads for cutting and assembly work. An HVAC contractor could use those same heads – especially the impact driver for sheet metal screws when doing ductwork – as well as the drywall saw, and possibly a jigsaw head. Power options can vary for the tools, from 12- and 18-volt cordless options to corded models, and there is even a pneumatic version of the motor in the marketplace. Most of the units run A versatile option from 0 to 20,000 Once left to the realm of oscillations per minute. do-it-yourselfers, professional Having an adjustable tradesmen are discovering speed, either by the trigger the versatility of multi-tools. or by a dial on the tool, is They can be used in tight advisable.

Standing out from the crowd
Jeff Patchell in Australia
I
n this day and age it is becoming more and more difficult to differentiate your business to get noticed by potential customers. Brand most certainly plays an integral role in the growth of most businesses; however, what many contractors fail to understand is that brand is more than just your logo on the side of your vehicle. Brand is how you present yourself and your overall demeanour, how you deal with your clients, the level of service you provide – it’s a range of elements all rolled into one that determines good business practice and how you are perceived by potential customers. Of course, it can also help if those potential customers notice you as you drive through the neighbourhood, so maybe that logo and vehicle are worth a second look. For Darren and Laney Clancy of Pipe Perfection Plumbers, a plumbing firm in Sydney, Australia, their point of differentiation came as the result of Darren’s love of vintage cars. “Our marketing plan had involved mail-outs to customers, web marketing and some fairly standard small business techniques,” Laney says. “We felt we needed to have a few things in addition to what we were offering. So, we sat down and worked out what we could do to stand out.” Pipe Perfection services a lot of older inner city homes. Some 90 per cent of their customers live in older homes, and Darren has become very good at repairing common issues in these older homes – so much so that he’s known by existing clients as a vintage house specialist. It was at one of these homes that Darren had his marketing light bulb moment. “I happened to be at a customer’s house where I saw a vintage Morris J van. They are as rare as hen’s teeth, but I knew I needed one from that moment on.”
He decided that a quirky mobile billboard was the answer to his marketing problems. Not only would a vehicle like this satisfy his love of old automobiles, Darren felt it would be perfect for the business. Darren and Laney eventually tracked down a 1958 J-van around 3,000 kilometres from home. Its restoration proved to be a true labour of love, but it turned out there was nice synergy between the old car and the old houses that Pipe Perfection services. And Pippy, as the van is known, gets covered in company branded advertising magnets when it hits the streets, which passers-by are encouraged to help themselves to. It’s so noticeable, it grabs attention everywhere it goes.
A different approach Laney Clancy came into the family business following a corporate career in marketing, but soon realised plumbing was a far different sector to most. “You can produce all the brochures in the world but unless you can stay in customer’s minds, they will forget you unless you keep in contact. If you don’t keep up that contact, they just open up Google or the local paper,” she says. “As simple as it sounds, Pippy has proven to be our point of market differentiation and ongoing recognition. Like it or not, you just aren’t going to attract the same attention in the street with a thumping V8 van.”
A plumbing connection Morris Motors began in 1912 when bicycle manufacturer William Morris switched to manufacturing cars. In 1927, Morris Motors bought Wolseley Motors Limited, another British vehicle manufacturer whose name is likely familiar to those in the plumbing trade. In 1889, Frederick York Wolseley and Herbert Austin expanded the operation of The Wolseley Sheep Shearing Machine Company Limited, now known as Wolseley plc, to produce cars. The first Wolseley motor car was produced in 1896. No longer in the vehicle business, Wolseley continues to be a major distributor of mechanical supplies.
