Equipped with larger 9/16" Flexicorewire rope center cable.
A muscular mid-size machine with more power, the Sewerooter T-4 quickly punches through tough clogs in 3" and 4" lines. A larger 9/16" Flexicore® cable does a better job of transferring the torque than traditional 1/2" cables do.
It gets down the line easier and clears clogs faster. And the portable workhorse is easier to handle in tight spaces, on stairs, and loading into your truck.

New radon report reveals residential radon levels across Canada are increasing
The recently released Cross-Canada Radon Survey of Radon Exposure in the Residential Buildings of Urban and Rural Communities reveals that approximately one in five people (17.8 per cent) in Canada live in buildings with radon levels at or above current radon guidelines of 200 Bq/m³, while 24.2 per cent of people live in buildings with levels between 100 and 199 Bq/m³. That’s a significant increase since the previous CrossCanada Survey from the late 2000s, which showed that 6.9 per cent of homes in Canada were at or above 200 Bq/m³
The report, led by researchers from the Evict Radon National Study team, is the result of a multi-year project designed to estimate the proportion of the Canadian population living in residential properties with radon gas levels above the Canadian guideline level of 200 Bq/m³ when radon mitigation is recommended, and the World Health Organization (WHO) reference level of 100 Bq/m³
The project also sought to detail the different levels of radon exposure in Canada by region, community, and residential building types. In terms of where homes with higher radon levels are located, 83.6 per cent of Census Divisions surveyed had at least one house whose radon level was at or above 200 Bq/m³. There were also 51 Census Divisions where roughly 25 to 50 per cent of houses contained radon at or above 200 Bq/m³. The average radon level in Canadian homes was found to be 84.7 Bqm³ .

The survey also showed significant differences in radon levels between regions, communities and building types. Radon levels were highest in Atlantic Canada, the Prairies, Northern regions, and the BC Interior. Single detached houses were found to more likely be at or above 200 Bq/m³, compared to semi-detached homes, which in turn are more likely to be at or above 200 Bq/ m³ compared to row houses. In addition, rural homes of all types were more likely to have a radon level of 200 Bq/m³ compared to urban homes.
Overall, the survey showed there are no areas of the country that are radon-free. While it noted that health providers and residents can use the findings to make informed health decisions, it stressed the importance of regular radon testing in homes. It also notes that further surveys, including of multi-family housing and of other Census Divisions are needed for a more complete estimate of radon levels in residences across Canada.

Quebec announces ban on fossil fuels in buildings by 2040 with one exception
Skilled trades are becoming a more popular career choice
A recent survey from Leger reveals that 40 per cent of Canadians have considered joining the skilled trades, despite the fact that only 13 per cent currently work in the sector. The survey, commissioned by Classic Fire + Life Safety and conducted last fall, found that 31 per cent of respondents who said they have considered a career in the skilled trades were female, while 42 per cent of students high school age or younger have considered working in the trades, and 35 per cent of university-aged Canadians have considered working in the trades. That may be because 52 per cent of people polled say they think more highly of the skilled trades now than they did a few years ago. classicfls.com

WHAT’S ALL THE BUZZ ABOUT?
GWP target prompts move to A2L refrigerants
We are once again in a phase of refrigerant changes in the refrigeration and air conditioning industry. Greenhouse gases are garnering much more attention in the sphere (pun intended) of global warming potential (GWP) and environmental concerns. HFC (hydrofluorocarbon) refrigerants are known as larger pollutants as far as carbon emissions and global warming or greenhouse gasses are concerned. That is one of the main reasons for their demise and eventual phase out. Enter A2Ls.
To keep it simple, the rise of A2L refrigerants is driven by the desire to have ideal HVAC/R synthetic refrigerants that are not overly toxic or flammable, and come with lower GWP numbers so they are not so harmful to the environment. Most of the legacy HFC refrigerants are A1 and the downside is their impact on the environment and higher GWP ratings.
It’s starting now. Some manufacturers are already using A2L refrigerants including R-32, R454A/B or C, and R455A. As of January 2025, many more Canadian and U.S. manufacturers will ship units with A2L refrigerants. Regulators have imposed a GWP limit of 750 for refrigerants used in residential air conditioning and light commercial air conditioning such as VRF systems and heat pumps effective January 1, 2025. Whereas R-410A is a very common refrigerant of choice in this sector, it has a GWP value of 2,088 so it can no longer be used for newly-manufactured systems. The GWP target is the main reason why we are getting these A2L refrigerants in today’s systems.
Cylinders that A2L refrigerants are shipped in have a red band in the top portion to clearly identify the cylinder’s contents as an A2L.

WHAT DO ALL THESE LETTERS AND NUMBERS MEAN?
There is so much buzz and chatter about A2L refrigerants. A1, A2, A2L, A3, B1, B2, B2L and B3 groups: these are classifications of different types of refrigerants created by ASHRAE in relation to refrigerant flammability and toxicity. Figure 1 shows the classifications, with flammability on the vertical scale and toxicity on the horizontal scale. Refrigerants that are classified as less toxic are assigned the letter A and refrigerants that are more toxic are assigned the letter B.
Regarding the numbers, the lower the number the less flammable the refrigerant is and the higher the number the more flammable it is with 1 meaning no flame propagation, 2L meaning lower flammability, 2 meaning flammable, and 3 meaning higher flammability.
What this means is a refrigerant such as R-410A falls in a group of A1-refrigerant, it is less toxic, and has low flammability properties − think of “it doesn’t add fuel to the fire. ”Refrigerants in group A1 are

the most desired refrigerants. Unfortunately, many of the synthetic A1 HFC refrigerants are desirable but also come with that undesirable higher GWP so their use in today’s market is limited.
There is another refrigerant, ASHRAE # R-290, which has great properties, has an extremely low GWP rating and is less toxic. If you are not familiar with this refrigerant number you may know its non-refrigerant name: propane. It is less toxic but highly flammable so this refrigerant falls in the category of an A3 refrigerant. It is a very good refrigerant in itself but due to its flammability its use is highly regulated and controlled when it comes to applications and refrigerant charge volume.
Why the L in the A2L and B2L categories? The L stands for lower. As you can see in Figure 1 in the mildly flammable 2 group there would be refrigerants in this batch that would be closer rated to a 1 than they would be to a 3. So, since they have a lower flammability rating within the #2 group, they get classified as an A2L or B2L. They are rated as a lower level, mildly flammable refrigerant meaning they do not ignite easily or propagate a flame as much as a highly flammable gas would.
How about B group refrigerants? As you may understand B-grouped refrigerants are not so popular because who really wants something more toxic? Refrigerant R-717 is classified as a B2L refrigerant meaning it is more toxic and it gets a B2L rating as it is slightly flammable. While the properties of ammonia as a refrigerant are good for refrigeration applications, the negative characteristic of it being slightly flammable and more toxic are factored into the design and use of systems. Typically, these refrigerants are used and applied in larger facilities with attention geared to safety and there are often trained professionals on site regularly controlling and operating the systems.
COMPATIBILITY
A2L refrigerants are not backward compatible with older and legacy systems. You will not be retrofitting old systems that originally used synthetic A1 HFC refrigerants such as R-410A or R-404A to newer A2L refrigerants because they are not designed or approved for use in A1 HFC systems.
IN THE FIELD
When it comes to working with these new refrigerants, your common hand tools will be compatible. Some tools such as refrigerant recovery machines and vacuum pumps may require some investigation to see if they are safely compatible with A2L refrigerants. Check with the manufacturers of these devices to verify they are safe to use with A2L. Refrigeration servicing and piping practices are not really different, but be more diligent when working with A2L refrigerants.
Image of typical Copeland scroll compressor labelling used for A1 refrigerant showing the model, commonly beginning with Z. The manufacturer’s new product line of scroll compressors tested and approved for use with A2L systems will have a similar design to older models but Y will be the first letter in the model name to easily differentiate them. Older Z model compressors would not be approved with A2L systems as they do not have the testing and approvals for A2L refrigerants.
Quite often you will see refrigerants in the “A” groups listed as non-toxic; honestly, I prefer to refer to these refrigerants as less toxic, as some of these refrigerants contain what is sometimes referred to as “Forever Chemicals” or Per- and Polyfluoroalkyl Substances or PFAS for short.
There is a movement in the EU to focus on the negative effects on humans when refrigerants contain PFAS. These potential health impacts are another reason why the refrigeration industry is focusing on ways to normalize natural refrigerants across many types of equipment.

ENERGY EFFICIENCY AND ENERGY SUFFICIENCY: WHY YOU WANT BOTH
Inthe November/December 2024 issue of Mechanical Business, I talked about building science as the foundation of being an energy contractor. This will be a necessary business model to accelerate the energy transition and renew housing to modern standards. This article lays out the core concepts of energy sufficiency and energy efficiency. I will highlight a recent project by Trim Tab that illustrates the powerful impact of these concepts on tenant quality of life.
What are energy retrofits and why are they important? Energy retrofits are building improvements that reduce energy use. This includes measures such as air sealing, adding insulation, and upgrading the HVAC system. I prefer to think of energy retrofits as the secret sauce of a high-quality renovation, because they strongly affect the things people want from their indoor environment − affordability, thermal comfort and fresh, clean air. The truth is, when quality of life is your aim, some retrofits can also increase energy use to address deficiencies in the indoor environment.
Sufficiency: Having enough energy services to meet one’s basic needs
Energy, as we learn in school, is the ability to do work. The availability of energy has been one of the great enablers of human progress for that precise reason. We can multiply our output through the use of energy to do work that would otherwise require manual labour. Think of how much further you can go with a car than a bicycle. And how much time you save by heating your home with a furnace instead of gathering wood for a fire every day. All of this is made possible through easy access to abundant energy and its inventive uses.
Examples of energy retrofits, clockwise from upper left: spray foam insulation; heat pump installation; air sealing from interior with Aerobarrier; installing a new electrical panel; and sealing envelope from exterior.
When it comes to the home, energy sufficiency means not so much the supply of the energy itself, but sufficiency in terms of end uses. I’m talking about things such as space heating, cooling, ventilation, hot water, appliances, and lighting. Each of these energy end-uses serves an important purpose in providing for our quality of life. If we are lacking any of them, then introducing them would require us to increase our energy use. This is not a trivial matter.
Tom Grochmal is founder and CEO of Trim Tab Energy Retrofits (trimtabretrofits.com), an energy contractor with a mission to renew housing and inspire better living.
Many people in affordable housing lack adequate cooling and swelter in the upper floors of their apartment on a hot day, causing heat stress. Having these basic needs met in a home is what I mean by energy sufficiency. Not having these basic needs met is one of the defining aspects of “energy poverty.” Ensuring sufficiency is at the core of what many of us do as mechanical contractors.
Efficiency: Reducing energy use to meet one’s wants
Energy contractors go a step further by striving for sufficiency and efficiency, so that a home or building has all its energy needs met, as efficiently as possible. Although bill reductions are often the headline benefit of energy efficiency, the main reason to incorporate energy efficiency in your renovations is that it simply leads to better quality housing, and all that goes with it, including even temperatures, fresh air, and noise attenuation.
Reducing energy use comes down to improving energy conversion efficiencies in equipment and reducing heating and cooling loads. Improved energy conversion results from installing higher performance HVAC equipment – such as a 300 per cent efficient heat pump. Lower heating and cooling loads are the result of a better sealed and insulated building envelope. The combination of envelope and HVAC upgrades is ideal. A better envelope means fewer drafts and warmer walls, control over the air you breathe indoors, and a heat pump that can operate to lower temperatures and satisfy heating needs.
Bringing it all together: Retrofitting stacked townhomes
At Trim Tab, we work on low-income rental housing and encourage housing operators to integrate energy retrofits with their unit turnovers. These turnovers present a rare opportunity to improve the building envelope while the unit is empty of contents and occupants, and some amount of renovation is necessary to prepare for the incoming tenants.
In a recent project, Trim Tab incorporated energy retrofits into the turnover process for stacked townhomes in Woodstock, ON. These units are about 20 years old, meaning they were built at a time when code already called for meeting some minimum energy efficiency requirements. However, upon assessment, we learned these units were drafty (as demonstrated by baseline air tightness testing), dim, reliant on portable air conditioning, and heated by a tanktype water heater for both space and domestic hot water.
The vertical stack heat pump is a more efficient heating system than the previous gas heating system and now introduces central cooling and ventilation. The vertical stack heat pump installed in a closet (left) and two vents outside the unit (right). It’s an elegant solution for a tight space.
The goal of the project was to modernize these units and lower energy costs for tenants, while working within the physical footprint of each unit and not adding equipment to the building exterior. It also had to be done in as short a time frame as possible.
The solution consisted first of drastically reducing air leakage (typically by at least 50 per cent) to get the unit to meet current construction standards for air tightness. Following that, we overhauled the mechanical systems by installing a vertical stack heat pump (VSHP) and a tall, slim electric tanktype water heater. The VSHP fits into a closet and integrates an energy recovery ventilator with a heat pump to provide all-in-one functionality – heating, cooling, ventilation, and dehumidification. Finally, we installed new LED lighting to brighten up the place.
Importantly, air sealing reduced the heating load to the point that we could heat the unit with the VSHP. The necessary ventilation capacity was determined through an ASHRAE 62.2 calculation, using the data collected from the energy audit and air tightness test.
The importance of air sealing: Getting to the root cause of air leakage uncovers issues that get worse with time if left unaddressed. In this case, the back window frame became a source of ingress for insects and snakes. The window frame was sealed up properly from the outside and inside.
The results are transformative for the following reasons:
• The significant focus on air sealing reduces drafts and the transmission of noise, smoke, and insects. We also uncovered deficiencies that would get worse if left unaddressed (see photos on pg. 27). When it is done properly air sealing has stacked benefits.
• The unit has balanced mechanical ventilation to provide a steady stream of fresh tempered air to maintain acceptable indoor air quality with no buildup of smoke, CO2 or moisture.
•The unit now has central air conditioning. The entire unit can be cooled on a hot day, and the removal of the window air conditioners means less damage to the building façade.
• The unit no longer relies on natural gas, meaning one less bill to pay. Decarbonization is a byproduct.
The solution highlights how quality of life can be improved through a combination of energy sufficiency (that is, addressing the lack of centralized cooling and ventilation) and energy efficiency (that is, reducing the heating requirements of the unit and increasing the conversion efficiencies by switching from a gas water heater to an air source heat pump). It’s a win for the tenant, housing operator, and the environment. The turnaround time for these projects is down to eight weeks and is continuing to improve.
Focusing on sufficiency without efficiency is wasteful. Focusing on efficiency without sufficiency overlooks the basic needs of a home that provides a healthy indoor environment and good quality of life. Bottom line, you want both sufficiency and efficiency when modernizing a home. This means improving both the envelope and mechanical systems. This means thinking of the home as a system. This is what energy contractors do.

THE CHALLENGE OF URBAN FIRES HOW MUCH WATER IS ENOUGH?
“How do you fight a fire with no water,” said a fire volunteer from the Los Angeles, CA fires. Millions of gallons of water were used from three tanks over a period of 12 hours, finally running some fire hydrants dry.
As Alberta is growing used to its northern wildfires, some comparison can be drawn to the recent L.A. fires and the resulting water use. Typically, northern bush fires are contained by planes which collect water from various lakes and rivers.
This past summer my good friend Mark Giles worked as a seasonal information officer with Alberta Wildfire. He explains some of the operations of containing a wildfire.
“Containment and control of wildland fires is achieved through various means in ground and air operations, including the use of water and retardant,” says Giles. “These operations can become more complex in areas where wildlands meet populated, or especially urban, areas − given the top priority is always the protection of human life and the safety of firefighters and other frontline personnel.
“So-called ‘fireguards’ or containment lines are used extensively to contain and control wildland fires, and can be very effective; however, the availability of water − and retardant when deemed appropriate and safe − will enhance the capabilities and options available to operational planners and commanders,” adds Giles.
“Water pressure in the system was lost due to unprecedented and extreme water demand to fight the wildfire without aerial support. This impacted our ability to refill the three water tanks supplying the Palisades causing the loss of suction pressure. This impacted 20 percent of the hydrants in the area, mostly in the higher elevations,” says the Los Angeles Department of Water and Power (LADWP).
WATER USE AND FIREFIGHTING
In the city, we use many fire hydrants to access water for fires. We used to teach our fourth-year apprentices the uses and parts of a McAvity fire hydrant. Their use in Canada started in 1903 and they were soon installed in cities across Canada. It is important to know the parts of a fire hydrant as well as how to repair and install one.
At the time we would go over all these details, as well as flushing hydrants through their 2 1/2 in. hoses. This would of course affect the water pressure in the mains. During a large usage, water pressure starts to lower in the city mains. The first point of access to firefighters are the fire hydrants placed throughout the city.

All high rises and commercial buildings come equipped with fire systems that must be boosted by fire booster trucks and Siamese connections. Where does this water come from? It comes from the city water mains and the reservoirs that supply them. In summer 2024, Calgary had a huge water main burst from a main built in the 1970s.
During its repair there was a tremendous strain on the city’s water use. Fortunately, there were no wild fires in Calgary and not many building fires during the water shortage. We also have an abundance of water in comparison to California.
CALCULATING WATER VOLUME
How much water does it typically take to put out an average house fire?
General estimates suggest it could take from 2,500 to 10,000 gallons of water.
How much water does a hydrant use? As it is similar to a faucet, a hydrant can use as much as you can supply it. This leads us to a more definitive question; how much water does it typically take to put out an average house fire? Many factors can affect this answer, however general estimates suggest it could take from 2,500 to 10,000 gallons of water.
Let’s take the smaller number and use 2,500 gallons of water. In L.A., approximately 12,000 homes burned down as of January 10, 2025. Using an average of only 2,500 gallons per home would work out to 30,000,000 gallons of water feed required for fire hydrants. This is only an estimate, as they were also using bush fire techniques or water bombing or fire retardant for some areas.
The daily average of water use for Calgary and surrounding areas is 600 million gallons per day. We were asked to limit use to 450 million gallons
or 25 per cent less, and that was hard for some people and businesses. This was nothing compared to L.A.
The LADWP is the second largest municipal water utility in the United States. As of 2021-2022, LADWP supplied approximately 447 million gallons per day. During the height of fire, the LADWP claimed on January 8 that it deployed 19 tanker trucks, each carrying 7,600 to 15,000 litres (2,000 to 4,000 gallons) to support firefighting efforts. The problem was feeding these trucks.
As of 3 a.m. January 9 the three feeder tanks for the Palisades Fire, containing approximately 3.8 million litres of water, had been emptied. It has been said that firefighting caused the demand for water in the area to quadruple the norm.
After taking in these facts, we as Canadians are blessed with lots of water and few fires, especially in Calgary and other large cities, at least for right now.

Effective water management in commercial buildings: A blueprint for sustainability and profit
Water
mismanagement is a silent saboteur, draining resources, tarnishing buildings’ reputations, and frustrating tenants. The stakes are high, whether it’s an undetected leak or outdated systems guzzling water. But effective water management isn’t just about avoiding disasters − it’s key to unlocking long-term financial stability and operational excellence for your customers.
Early warning signs of water issues
Water problems often develop out of sight, gradually worsening until they lead to significant damage. Identifying the warning signs early can prevent costly repairs and operational disruptions. Here are the key indicators to watch for:
• Unexplained high water bills
A sudden increase in water bills, without a corresponding change in usage, often points to hidden leaks, inefficient plumbing fixtures, or irrigation systems using more water than necessary.
• Low water pressure
Simon Brunet is founder and president of Connected Sensors. He has researched and crafted a solution to mitigate building risk and revolutionize water management. He can be reached at simon.brunet@connectedsensors.com.
Inconsistent or weak water pressure typically results from blockages, sediment buildup, or pipe corrosion, restricting water flow through the system.
• Visible signs of damage
Stains on ceilings, peeling paint, or warped flooring indicate water seeping into places it shouldn’t, often due to slow leaks or inadequate waterproofing.
• Unusual noises in the plumbing
Hissing, whistling, or gurgling sounds in the pipes signal trapped air, high water pressure, or water escaping
When it comes to water leaks, identifying the warning signs can prevent costly repairs and operational disruptions.
Water damage makes up 50 per cent of all commercial property insurance claims.
The cost of neglecting water management
Ignoring water issues allows problems to escalate, leading to serious consequences. Here’s what’s at stake. Leaking pipes, inefficient fixtures, and poorly managed irrigation systems waste thousands of gallons of water. With the cost of commercial water, even minor leaks can lead to significant expenses, draining resources month after month.
A single, undetected leak can escalate into catastrophic structural damage in as little as seven days. Water seeps into walls, floors, and foundations, weakening their integrity and paving the way for expensive repairs, prolonged operational downtime, and the likelihood of hefty insurance claims.
In addition, persistent moisture creates the perfect environment for mould, mildew, and bacterial growth, posing serious health risks to tenants and staff. Poor water quality or management can expose the owner to lawsuits and regulatory scrutiny.
Other possible consequences of chronic poor water management include regulatory penalties, increased tenant turnover and vacancy rates, and decreased property value.

A STRATEGIC APPROACH TO WATER MANAGEMENT
Effective water management requires a multi-pronged approach that leverages technology, proactive strategies, and tenant collaboration. The most impactful methods you can suggest to customers are:
• Install smart water monitoring systems
Smart water monitoring systems provide real-time data on water usage, identifying inefficiencies and leaks with pinpoint accuracy. These systems enable property managers to act quickly, preventing minor issues from snowballing into costly disasters.
• Upgrade to water-efficient fixtures
Switching to low-flow toilets, aerated faucets, and high-efficiency appliances reduces water consumption without sacrificing performance. Many jurisdictions also offer rebates for installing water-efficient fixtures, making this a cost-effective upgrade.
• Optimize irrigation systems
Traditional irrigation systems often waste significant amounts of water. Replacing them with smart irrigation controllers, drip systems, and drought-tolerant landscaping can cut outdoor water use by 20 to 60 per cent.
• Adopt rainwater harvesting
Rainwater harvesting systems collect and store rainwater for non-potable uses such as irrigation and toilet flushing. This reduces reliance on municipal water and provides an eco-friendly alternative, especially in areas with frequent rainfall.
• Implement greywater recycling
Greywater recycling systems repurpose water from non-potable sources. Though the initial investment is higher, the long-term savings and sustainability benefits make this an attractive option for large properties.
Your customers will appreciate any help you can provide with educating tenants and staff. Even the most advanced systems won’t succeed without human cooperation. Educating and incentivizing tenants and staff on water conservation practices − such as reporting leaks, turning off taps, and using waterefficient appliances − fosters a culture of sustainability. Offer regular maintenance packages. Preventive maintenance is the building owner’s best defense against water-related issues. Schedule regular water audits, inspections, clean filters, and replace worn-out components to ensure water systems operate efficiently.
THE BENEFITS OF PROACTIVE WATER MANAGEMENT
Modern water systems are more than just practical − they’re a selling point. Investors and buyers love buildings that boast efficiency and sustainability, and effective water management checks both boxes. Add green certifications such as LEED to the mix, and your customer will have a building that commands higher market value and delivers a strong return on investment.
As an added benefit, investing in proactive water management lowers the insurance risk profile and premiums. With fewer claims and ongoing maintenance, your client is not just saving money; they’re keeping the property safer and the budget healthier.
Many government programs and utility companies offer rebates for waterefficient fixtures and technologies. These incentives help offset installation costs, making investments in sustainability even more rewarding. Staying on top of conservation regulations doesn’t have to be a headache. Automated water management systems make compliance a breeze by tracking usage and generating detailed reports.
WRAPPING UP
Effective water management is more than a checkbox on a to-do list. It’s a strategic investment in any building’s future. By embracing smart systems and proactive strategies, your customers aren’t just managing water; they’re optimizing operations, cutting unnecessary costs, and elevating their property’s market appeal. From happier tenants and higher property values to reduced risks and greater sustainability, the advantages speak for themselves. Adding water management to your portfolio isn’t just about conservation − it’s about driving growth, profitability, and long-term success.

True to his roots Mark Critch:
Canadian actor, writer and comedian Mark Critch started his work on Canada’s longest-running TV comedy series, This Hour Has 22 Minute s, as a writer. He would later join the show as a regular cast member in 2003. Critch started honing his skills in front of an audience at 15. His coming of age is captured in Son of a Critch , Critch’s first book which has been adapted for television. Critch plays his father Mike in the series.
“I grew up in St John’s, NL, and my dad was a newsman. He was a household name in Newfoundland and Labrador reporting on small town crime and trying to make it seem like big-time crime. I went to St. Theresa’s Catholic school as a kid raised by the nuns and it’s a big part of our show, of course, the Catholic schools and education,” says Critch.
It was in high school that he caught the acting bug, inspired by a theatre arts teacher. “I started when I was 15. I rented out the Longshoremen’s Protective Union Hall in St. John’s, and with three other guys we put on a sketch comedy show. We’d do that several times a year and with that right out of high school I was an actor. It was the actor’s life for me performing my own work − I haven’t looked back since.”
“I’ve
been able to travel our country, which a lot of Canadians don’t really get to do because of the size of the place. I have a real sense of this great country we have.”
Critch’s parents realized he was serious about his career and were supportive but his dad did suggest he get a regular job “in case” but Critch felt if he had a safety net, he might just fall into it. “I never really wanted to get rich and famous or anything, I wanted to write and perform my own work because I had a lot of mentors and that’s what they did. It was weird in those days to see people from Newfoundland on television. We had Gordon Pinsent, who was a dear friend, and he was very well known. But then CODCO was the first time I saw people on TV using our own accent and not trying to sound like they were from Toronto or someplace else, and telling Newfoundland stories. That was something which appealed to me.
In the three-channel universe back then, when you could see someone who sounded like you talking about things you knew on the same box where Happy Days was, you’re like oh okay, there is a world in which you can be yourself and tell your story. That was always my dream.”
This Hour has 22 Minutes Season 32 and Son of a Critch Season 4
FRONT ROW SEAT
Critch has had a busy career and there have been many highlights. “The biggest now is having Son of a Critch happen, but in 22 Minutes there have been so many big little moments, whether it was lighting up a joint in the prime minister’s office with Justin Trudeau or going to Russia and planting a Canadian flag in Red Square because the Russians had planted their flag under the polar ice cap, claiming it as theirs. We claimed Red Square as ours and the Russian police showed up. Or being in Afghanistan, that was a great moment, performing for the troops over there, until I had my act interrupted by Taliban rocket attacks − that was a wakeup call.
“My career with This Hour has 22 Minutes has been such that I’ve been able to have a front row seat to a lot of Canadian history; interview prime ministers and being there sometimes in the middle of a historic moment and get to know these people as real people. I’ve been able to travel our country, which a lot of Canadians don’t really get to do because of the size of the place. I have a real sense of this great country we have.”
A PROUD HISTORY
Critch is happy to talk about Newfoundland and Labrador’s proud history, particularly events before it joined Canada. In the 2016 CBC documentary Trail of the Caribou (available on youtube.com), Critch and Allan Hawco retrace the steps of the Newfoundland Regiment through Turkey, Belgium and France. “We went everywhere they went in the First World War. That’s something that really defined the next 100 years of Newfoundland and Labrador history. I mean we were our own country with our own passport, our own currency, and our own prime minister.
Behind-the-scenes with Mark Critch (L) and Benjamin Evan Ainsworth (young Critch) in hair, makeup and wardrobe for his scene.
Released in 2018, Critch’s popular early life memoir Son of a Critch, would be adapted for television in 2021. Son of a Critch was the winner of the Margaret and John Savage First Book Award (non-fiction) at the Atlantic Book Awards, and shortlisted for both the 2019 Stephen Leacock Memorial Medal for Humour and the 2019 Kobo Emerging Writer Prize. It was also longlisted for the 2019 RBC Taylor Prize. His second book, An Embarrassment of Critch’s, was also shortlisted for the Stephen Leacock Memorial Medal for Humour in 2022.
Then the Newfoundland Regiment went off to the First World War, and most of the regiment was wiped out at the Battle of BeaumontHamel. There was a whole generation of young future leaders and politicians and business leaders all wiped out in one day,” notes Critch.
The losses sustained during the war, particularly at Beaumont-Hamel where only 68 of 800 soldiers in the Newfoundland Regiment were able to answer rollcall the next day, had a profound socio-economic impact on the Dominion of Newfoundland. “That was one of the major, major factors to kind of crippling the economy here, which eventually led to us joining Canada. That one battle really changed the whole course and the future of the province − it is quite remarkable.
“From there the regiment went on to have great successes and afterwards got the designation ‘Royal.’ Tommy Ricketts was with them and was the youngest person ever to get the Victoria Cross at 17. They are quite an amazing group who really fought above their weight and really made an impact in the war. We went and followed the Trail of the Caribou, which is National Parks of Newfoundland and Labrador land in Europe that has big statues of the caribou − the emblem of the regiment. Each one marks a battle. It was quite a moving, powerful experience to be there,” says Critch.
He is currently working on a new novel set in Newfoundland at the end of the Second World War that is based on a true story. “It’s a bit different than the first two books because I don’t think I could do a third memoir. I’m not Churchill, you know. I’m only 50 and I think two memoirs is enough,” chuckles Critch.
“There was a lot of German submarines here in the waters off the coast of St. John’s, and St John’s was attacked a couple of times. Convoys would leave from St. John’s to get over to Europe with troops, supplies, iron ore, ammunition, and things like that. The U-boats would patrol outside St. John’s Harbour, trying to sink as many of those convoy ships as possible. A U-boat surrendered at the end of the war in a small town called Bay Bulls and the book is about that.”

Combustion conundrum
When it comes to boilers, we tend to spend a lot of time discussing which piping method is best and/or which zoning method rules. What we don’t spend too much time on is the combustion side of things.
The combustion of a gas fired appliance such as a boiler falls into three major parts. The combustion air, the actual flame, and the flue exhaust. Those three components are going to be responsible for ensuring a safe and efficient flame.
I want to stress that the two best places to get information for all these components are the manufacturer’s installation manual, and the gas code such as CSA B149. It is also important to note there will be overlap between residential and commercial but there are also going to be some differences depending on the set up.
Negative pressure or an undersized combustion intake pipe will cause you intermittent headaches on some jobs.
DIRECT PIPE VERSUS ROOM AIR
There are two options for combustion air. Either direct pipe (bringing in combustion air directly to the appliance) or room air. There are proponents for both. For appliances under the 400 MBTU/hr limit, there are some good arguments for the direct pipe approach. It is relatively simple, provided you have the room, and it takes the room pressure out of the equation. Manufacturers will usually provide guidelines as to which size pipe to use depending on the length of the run.
With larger and much larger appliances, I have seen snow and ice buildup inside the appliance because they draw a tremendous amount of air for the combustion cycle and in the middle of a snowstorm you will be pulling a lot of air and atmospheric conditions will apply.
For the room air option, you will need to provide a room opening according
to the manufacturer’s manual which may or may not comply with the gas code. CSA B149 states there must be a permanent air supply opening having a total crosssectional area of not less than 1 sq. in. for each 30 MBTU/ hr (30,000 BTU/hr) when using the room for combustion air. However, some manufacturer manuals state there must be an opening of not less than 1 sq. in. for each 4,000 BTU/hr. That is quite the difference. The main goal of the manufacturer’s installation manual is to ensure the room never goes into a negative pressure.
Manufacturers will usually provide guidelines as to which size pipe to use depending on the length of the run.

WORKING IN UNISON
The actual combustion of the fuel is going to be dependent on a few things, including gas and gas pressure. Gas pressure is going to be a result of the regulator, pipe sizing and pipe length. All of these items must work in unison to provide the appropriate gas pressure to the appliance. Starting with the regulator, it is important to get a regulator that can adequately support the appliance you are installing. In some residential cases you won’t need to worry about this if the regulator from the gas supplier can adequately handle the total building load.
In commercial applications it may be necessary to use multiple regulators in a building with a specific one just handling the boiler load. In cases where an additional regulator must be used, be sure to give some pipe length between the regulator and the boiler. If they are too close you will not have enough pressure built up in the lines to adequately handle the fluctuations in pressure during light off and modulation.
We’ll come back to modulation when we discuss exhaust but this plays a very large role in overall combustion efficiency. Pipe sizing plays a role as well. Undersized piping usually happens because we didn’t factor in the equivalant length of the fittings.
Gas pressure, pipe sizing and pipe length must work in unison to provide the appropriate gas pressure to the appliance.

TUNING THE BOILER
Next on the combustion list is “dialing in the boiler” or tuning. The primary byproducts of combustion are CO₂ and H₂O. Some access O₂ is necessary for clean, safe and reliable combustion. Too little and you do not have a clean burn. Too much and you lose efficiency. You usually dial in combustion levels (primarily O₂ and CO₂) when tuning a boiler. As O₂ goes up, CO₂ goes down and vice versa. You usually dial in at high fire and at low fire but some boilers have multiple points of combustion that need to be set.
How often a boiler should be tuned depends on a number of variables.
Shedding some light on “light off”
There are also CO limitations to be aware of. High levels of CO can be caused by a number of things, but the main culprits are either a cracked HX or the unit needs tuning.
I get asked a lot as to how often a boiler should be tuned. That’s a hard question to answer as there are a number of variables such as the time of year, air quality, gas quality, and boiler operations, but I will tell you that it’s very difficult to do it too often. On the flipside, it’s very easy to not do it often enough.
The primary byproducts of combustion are CO₂ and H₂O.
Light off refers to when the appliance, such as a boiler, ignites. It is the stage of the sequence of operations when you have ignition. The fuel and air mixture flows past either a HSI (hot surface ignitor) or spark generator and that mixture combusts. The first few moments of that combustion are called light off. After light off, the flame sensor will prove flame and then the ignitor or spark generator will stop and the burner will usually modulate either up or down depending on the delta T between the demand temperature and the incoming water temp.
Great People. Efficient Solutions.
EXHAUST VENTING
Finally, on to exhaust. Again, there are some overlaps between residential and commercial but the larger the application the more complex exhaust venting becomes. For smaller residential applications the manufacturer will provide a chart that states how long you can vent with a certain size pipe. This is referred to as equivalent length.
For commercial it’s more about the draft pressure. There is a reason for this. The equivalent length method is not a substitute for good engineering practice to determine acceptability of a vent system. This is due to varying burner modulation rates, ambient air temperatures, and flue gas temperatures, among other factors.
The key word to take note of here is the modulation rate. This is where things can get complicated for commercial installs. If you have a 1,000 MBTU/hr boiler with a 10:1 turndown, you have a maximum firing rate of 1,000 MBTU/hr and a minimum of 100 MBTU/hr. The burner modulates its fan speed, and the gas valves either allow or pull a certain amount of gas in, to meet the target combustion to satisfy the load.
So, the air we pull for combustion can change, the gas can change but our exhaust pipe cannot change. It is a fixed pipe size and length. This problem becomes more complex when we are talking about multiple boilers. If you have a vent pipe sized for two or three 1,000 MBTU/hr boilers but it’s the beginning of fall and the load can be maintained by one boiler at low fire, the flue vent may have a hard time maintaining draft pressure. A few things can help with this, including a modulating flue damper which effectively changes the “size” of the draft as far as the boiler is concerned.
The other item that I would highly recommend for a multiple boiler system is a draft fan. These fans can modulate to maintain whatever draft pressure the boiler requires regardless of how many boilers are firing and at what rate. Truly this is the right answer when it comes to venting large boilers with a high turndown rate and multiple boiler applications.
HEAT EMITTERS
System not delivering?
Maybe the problem is not in the mechanical room …
Acommonservice call for a hydronic system usually revolves around the mechanical components in the mechanical room. As the troubleshooter, you may start your diagnosis by cranking up the thermostats to check individual zones for operation. Next, you’ll ensure the pumps and/or zone valves operate and you have adequate flow. What is often overlooked is the distribution system, specifically the heat emitter. Perhaps the one I see most compromised is the common fin tube. First, ensure that the fins are in the correct direction. Cool floor temperature air comes into the bottom of the enclosure and convects upward. They do not work very well if the fin openings are from front to back − don’t laugh.
The heat emitter assessment and cleaning will take time, maybe hours or a day.
By Bob “Hot Rod” Rohr
Bob Rohr is a trainer with Caleffi, and was the recipient of the 2020-2022 CarlsonHolohan Industry Award of Excellence. He has 40+ years of experience as a plumbing, radiant heat and renewable energy contractor.
Calculating required output
If there are underperforming areas of the home, check that there is adequate fin tube to cover the load. Use the manufacturer’s rating chart for expected output. Fin tube output is based on the average water temperature (AWT) through the loop. Measure incoming temperature after the system has been running, and the temperature at the end of the loop. Add these values together and divide by 2. For example, 180°F supply water temperature (SWT) and 160°F return water temperature (RWT) averages to 170°F. Use that number for output.
The next step is to make sure there is an air space below the front enclosure of the fin tube. If flooring was added or carpet installed over a previous wood floor, this can cut down on the air space, and lower convection and output. Dampers need to be fully opened. Pet hair can also restrict air flow considerably. Check and vacuum as needed. However, be careful with the vacuum. Fins damaged from aggressive vacuum cleaner operation will reduce output. Front enclosures need to be in place and custom wood covers need to have adequate air slots on top and air space below for convection currents to flow across the fins.
Manual bleeders are often found on baseboard ells. If you hear water flowing, you may need to do some bleeding at the individual runs.
The system needs to run and get to thermal equilibrium to get accurate heat output assessments. Hydraulic equilibrium is reached when the SWT and RWT are staying stable. This tells you the heat emitters are putting their full output into the space. At this point take your SWT and RWT measurements. Some fin tube ratings have a “pick up factor” added. If you are dealing with a new or tightly-insulated home, divide by 1.15 to get a more realistic output number. Even today, the rating tables published by baseboard manufacturers list heat outputs at water temperatures up to 220°F, and in some cases up to 230°F. An example of such a rating table is shown in Figure 1.
A footnote that often accompanies a fin tube rating table states the ratings include a 15 per cent “heat effect factor.” When conceived decades ago, this factor was meant to boost the tested heat output by 15 per cent to account for the baseboard being installed at floor level, where surrounding air temperatures were often significantly cooler than air temperatures higher in the room.
Figure 1 Rating Table
Today’s homes do not have such drastic room air temperature stratification, and as such, the heating effect factor is not appropriate. Conservative design practice is to divide any heat output ratings that include the heating effect factor by 1.15 to remove it and use the corrected value when sizing the baseboard.
Based on typical rating tables similar to Figure 1 (see pg. 46), one might assume that a fin tube baseboard cannot operate at water temperatures under 150°F. This is not the case. Any heat emitter will release heat as long as the fluid inside it is warmer − even slightly − than the surrounding air temperature.
Issues to watch for
Air handlers (AH), fan coil units (FCU), hydro-coils, and kick space heaters are examples of forced convection heat emitters. A fan forces air across the fins to increase the output. These are also prone to plugged fins as the higher airflow tends to pick up and pack in dirt, pet hair, etc. Again, a portable vacuum cleaner with a soft brush end is your friend for servicing any coil or fin tube. Fin combs can help straighten out damaged or crunched fins.
Suspended tube systems need proper insulation. Rim joists should always be rigid foam sealed with spray foam, in my mind. There can be a huge infiltration loss around that exterior framing. A few cans of expanding spray foam can save plenty of heat loss. It is a gift that keeps on giving.
Constipation in radiant systems usually comes from deterioration on the inside of the tube. Take a sample of the system fluid, water or glycol. Look at it, smell it, and let it settle overnight. Most system fluid will take on a brown or gray tint from the metals in the system. That is normal. Fluid should not be black, dark brown, gritty, or smell like an old locker room.
Non-barrier radiant tubing should always be suspect. O2 ingress corrodes ferrous metals, pumps, expansion tanks, and steel nipples. This can form a sludge that coats, or even plugs, the tube. Systems that constantly take on fill water can also scale from the mineral precipitation.
Damaged and plugged fin tube baseboard.
Cast iron or panel radiators should be inspected, also. Some panel radiators have fins inside. They have coarser spacing, but may still be plugged up. There are some convection currents involved with radiators. So, make sure they are not blocked by custom enclosures, or a box across the top. Sometimes radiators have valves on them for adjusting flow or isolating the radiator. Of course, these need to be wide open for maximum performance.
Other systems
Inspecting radiant tube systems gets more complicated. If you can gain access, be sure it was installed to manufacturer’s requirements. Of course, you won’t be able to inspect the work that has been buried in concrete. Transfer plates need to be tight against the floor. Loop length can sometimes be calculated at the manifold as the foot markers are printed on most tube loops.
Example of clogged radiant tube.
Several types of hydronic cleaners can be used to bring these dirty systems back to better operating conditions. Some cleaners are strong detergents. These work well on systems with oily, or greasy, fluid, and old glycol systems. If the system shows a lot of white scaling from hard water deposits, an acid-based product may be a better option.
Boiler and pump manufacturers have a water quality specification in their manuals. A few inexpensive testers can provide a picture of the fill water compatibility. A pH tester, hardness test kit, and a TDS meter are good to have on hand. These tools can save you so much time and energy. Or you can send a sample to outside companies for a deep analysis. Local wholesalers and reps can steer you to a test option. Add a hydronic system conditioner and get the manufacturer’s test kit and check it every year or two.
Promote the heat emitter assessment and cleaning as a service you offer to get or keep systems working efficiently and saving your customer fuel dollars. Equipment warranty could hinge on proof of required service. So, when the mechanical room looks sound, take your troubleshooting skills off to emitter land.
Water quality on the job should always be tested.

Job Title: Hydronics specialist – estimator

Dustin Wright: The specialist
“When I started at Canada West, that’s where I got more into the service end, as well as still being able to manage a smaller construction project. I started doing a lot of boiler retrofits, doing some intermittent chiller system installs, as well as service on high efficiency and condensing boilers. That’s where I grew this passion for hydronics,” says Dustin Wright, a Red Seal plumber and gasfitter at Calgary, AB’s Canada West Mechanical Ltd. “It’s something that’s always changing, always updating.”
Growing up Wright says he was always interested in the trades, and originally wanted to be a pipe fitter. After having trouble finding a job in that field, he instead began a plumbing and gas fitting apprenticeship with Calgary’s Botting & Associates, working on large-scale commercial projects. From there he joined Canada West Mechanical, where he is currently the company’s hydronics specialist – estimator. The company provides HVAC/R and hydronic services to the industrial, commercial and resource sectors.
Wright says approximately 60 per cent of his work is servicing, while 40 per cent involves construction projects. “I estimate a lot of our boiler retrofits and intermittent chiller system installs, and am servicing mostly high-efficient condensing boilers. So, fire tubes, water tubes, we do a bunch of mid-efficient boilers as well. And we have some natural draft at some of our sites. We do have chillers on a lot of our sites too, that we maintain through our maintenance contracts.”
Wright says he enjoys the challenge of designing a hydronics system, as well as learning about and working with new technology. “There are lots of projects I’ve been trying to get into.
I mean, you’re seeing a lot more starting to include heat reclamation, heat exchangers to extract even more heat from the flue gasses, and the associated equipment. There are also the CHP (combined heat and power) systems that are coming over from Europe. Every unit is different in its own way. So, when it comes to troubleshooting a system and trying to figure
out where the problem lies, it can be a bit more of a challenge, depending on what you’re working on.”
The variety of projects Canada West undertakes is also a highlight for Wright. One memorable project involved a chiller retrofit in Banff that required equipment to be flown in and out by helicopter. Another involved constructing an intermittent chiller system for an IT company for computer ECMs and applied large environmental test chambers. Wright says the entire system was built on a truck that the IT company could move from facility to facility. “That one took about five months, but it was good. It was a lot of extra planning, but it was definitely a cool one.”
Wright is currently completing his apprenticeship in refrigeration and air conditioning, as well as a hydronics design and installation program. “I think education is your best tool to have in the trade, so my main goal is just to stay focused on school. I know it’s hard to take two months every year to go to school, but I keep doing it and keep growing myself professionally. And the owners here are extremely supportive of everyone’s education and any special courses. They encourage us to advance ourselves as far as we can.”

SEPARATION
Mastering the flow
Water flows all around us − through pipes, heating and cooling systems, and even in the air we breathe. Yet it also follows a complex balance of pressure that controls its movement. Hydraulic separation is key to maintain this balance in hydronic systems, ensuring smooth and efficient water flow in a closed-loop hydronic system to ensure optimal performance and comfort.
Role in retrofit applications
To start, we require a basic understanding of how a hydronic system works. A hydronic system is a heating or cooling system that uses circulation of a fluid, typically water, to transfer thermal energy. Hydraulic separation plays an important role, because it balances the flow between different pipes.

Primary piping refers to the loop that manages everything on the boiler side. Secondary piping, or distribution piping, handles the system side, including system circulators or zoning devices such as zone valves. By separating the primary and secondary piping, hydraulic separation is achieved. This separation allows the system to operate efficiently with no interference between the primary and secondary circuits.
With a basic understanding of hydraulic separation. let’s discuss why it’s important for retrofit applications. Both the closely spaced tees and hydraulic separator methods are suitable to decouple the primary/secondary circuits. The optimal choice would vary depending on certain job requirements.
Older systems were typically designed with a single pump to manage the system’s full load, and the flow required through the boiler. New condensing boilers have specific flow requirements recommended by the manufacturer, and so changes to the existing pump may need to be made. Hydraulic separation is especially crucial for a retrofit project so that the new primary circuit can operate with no interference from the existing secondary circuit.
Effective hydraulic separation is crucial for hydronic heating system retrofits.
Methods to achieve hydraulic separation
Closely spaced tees are a standard method used in residential hydronic heating systems. When using this method, it’s important to ensure the tees are spaced four pipe diameters apart. For example, if you’re using a pipe with a one-inch diameter, the centre-to-centre spacing between the tees should be four inches. If you space them further apart than the recommended four inches, you’ll encounter

issues with what is commonly known as “ghost flow.” The result of this excess spacing is unwanted flow in the secondary loop.
If done properly this method of hydraulic separation ensures proper design flow in the primary loop. If the system is installed correctly, the pressure drop across the tees is negligible, which prevents water from entering the secondary loop until needed.
Another method of achieving hydraulic separation is also the one that I consider most effective. This method utilizes a hydraulic separator, a device designed to keep hydronic heating systems running smoothly. The beauty of hydraulic separators lies in their simplicity; they are easy to install, with supply flow entering at the top and return flow exiting at the bottom.
From an installation perspective, hydraulic separators are often the preferred method since they drastically reduce time and labour. Simple installation also eliminates the risk of installation errors you might experience when using closely spaced tees.
Let’s get technical
Further understanding of hydraulic separators requires a more technical deep dive. Positioned in a specific spot within the system, the hydraulic separator serves as a low-pressure zone with a nearly zero pressure drop, effectively decoupling the primary and secondary circuits. This design allows each loop and circulator to operate independently without interference.
In many systems, the secondary piping will have multiple circulators. Using a hydraulic separator ensures that each system circulator performs at its designed duty point.
A misconception about sizing a hydraulic separator is that it should be sized based on the pipe size it connects to. But the truth is it should be sized based on flow. For example, when reviewing product submittals, you’ll notice that a two-inch union connection will have a different flow rate than a twoinch flanged connection. This is something to be mindful of when selecting a hydraulic separator.
Hydraulic separator with coalescing mesh helps eliminate air and debris from the system piping.
Figure 1 The difference in gallons per minute between each separator, specifically the two-inch models
Hydraulic separators not only ensure proper flow but also provide efficient air and dirt separation. A coalescing mesh helps remove unwanted air and dirt from the system inside the separator’s body. Many manufacturers now offer hydraulic separators with magnetic dirt separators to capture metallic debris in the return piping. It’s a common recommendation to use magnetic separators for retrofit applications. This provides critical protection for your boiler’s heat exchanger and the rotors in ECM pumps, which will help with the overall system efficiency.
Resources
To continue learning and deepen your understanding of hydraulic separation, there are some excellent resources available. For example, I frequently rely on webinars such as Taco Tuesday by Taco and Coffee with Caleffi by Caleffi, which are great tools to enhance knowledge.

Installation dos and don’ts
The following installation “dos and don’ts” will impact the longevity of a boiler system.
DO use the onboard control system that most manufacturers now include with their boilers. No one, not even the controls contractor, understands how to stage, modulate or optimize boilers as well as the manufacturer. These days, onboard boiler controls can control On/Off operation, modulation and sequencing, primary boiler pump speed, and even outdoor temperature reset.
Remember, boiler control can still be integrated into the Building Management System (BMS) for remote monitoring and communicating alarms, however operational control conforms to manufacturer protocol for both condensing and non-condensing boilers and primary pumps.
Residential gas boiler installation
DON’T power the primary boiler pump(s) through the boiler(s) if the required pump motor amperage exceeds the amperage rating of the associated boiler pump motor relay. This will cause you to blow a fuse in the boiler and the pump will lose power. The best way to avoid this common scenario is to add an external contact to provide electricity to the pump.
Emergency stop is usually placed inside the boiler room.
breaker will immediately shut off the fuel or energy supply. Make sure to consult local codes to see if they have additional requirements.
DON’T use venting material that was installed for existing non-condensing boilers for newly installed condensing boilers. Condensing boilers require either Category II or IV vent, depending on whether the draft is natural or pressurized. The sizing of the vent may also be different for a condensing boiler.
DO consult local jurisdiction requirements for emergency stop wiring to determine how many and where emergency stop devices should be installed. Many jurisdictions require ASME CSD-1 controls and safety devices for automatically fired boilers, in particular, an emergency boiler “STOP” switch at every entrance to the boiler room. This emergency stop is
usually placed inside the boiler room so that in the event of any emergency you can hit it on your way out of the room, thus disabling the equipment. Activation of the remote shutdown switch or circuit
DO consult with a venting expert to specify an engineered vent system for gas-fired boilers.
DON’T expose boiler pumps to magnetite (the sludge that leaches from piping and equipment) when using pumps with electrically commutated motors (ECM), which use a magnet to make the impeller spin instead of the shaft. The magnet attracts this metallic material, causing it to build up inside the pump leading to premature failure.
DO pipe condensate to a neutralization kit to raise the pH before it is discharged into a drain. The condensate should be able to drain by gravity from the boiler through the condensate trap and finally the neutralization kit before going down the drain. Make sure the boiler is installed at a higher elevation to permit this drainage, otherwise, you will need to install a small condensate pump to facilitate drainage.
Always install a neutralizer kit to prevent boiler condensate from damaging drainage piping.
DO install a magnetic filter to protect ECM pumps that use a magnet to attach the impeller.
DON’T overlook local codes or assume one jurisdiction has the same requirements as the last project you designed. Local jurisdictions vary in terms of required boiler clearances, gas venting, safety measures, and more.
DON’T discharge condensate from a condensing boiler directly into a drain. This condensate is highly corrosive to pipes and equipment due to its low pH and must be neutralized before disposal.
A magnetic filter should be used to avoid magnetite build-up.
DO remember that it is much easier to meet code requirements during installation, rather than “fixing” code violations after the installation is complete.

2024 Bad and Ugly Contest winners announced BACKFLOW PREVENTION
Logan Skagen, backflow prevention (BFP) tester, and Dylan Gerlack, cross connection control inspector, are the winners of the Western Canada Section of the AWWA Cross Connection Control Committee’s (WCSAWWA) 2024 Bad and Ugly Contest.
The contest is open to BFP testers and inspectors who can submit photos and descriptions of bad or “ugly” cross connections while on the job. It is designed to increase awareness of the dangers of bad cross connections and educate water industry representatives in the field.
Gerlack is manager, CCC for EPCOR Water Services. He won for his image of a bypassed air gap (AG), something he says he sees often. “As part of our cross connection control program (CCCP), EPCOR requires customers who need to access water in our hydrants to apply for a hydrant permit. This allows us to know who is interacting with our infrastructure,” he explained.
“Part of the permit approval process is requiring the customer to send us pictures of the AG that is permanently fixed to the water hauler or the vessel they intend to fill up. The photo must include a tape measure to show the unobstructed vertical distance between the lowest point of the water supply outlet and the flood level rim of the fixture or device into which the outlet discharges. This distance must be at least two times the pipe diameter and no less than one inch,” said Gerlack.
“An AG is the most effective and reliable form of preventing water from reversing flow and creating a potentially hazardous condition in the water distribution system that is feeding water to the hydrant. The risk associated with using an AG to prevent backflow is they are vulnerable to bypass arrangements that can nullify its effectiveness, as was the case with this picture submitted in 2024 for approval. What had previously been an approved AG of six inches the previous year had a section of rubber hose clamped to the pipe, negating
the air separation between the fill pipe and the tank. After a discussion with this customer, they removed the rubber section of pipe along with the clear garden hose that was submerged in the tank and re-submitted pictures for approval,” he explained.
Skagen, who works for A+E Air Plumbing and Heating, won for his image of a cross connection on a potable water line in a mechanical room. “While upgrading water lines in a mechanical room, I observed there was a severe potential cross connection on a potable water line in the mechanical room,” he wrote. “On one half-inch branch line there was an eyewash station and just a few feet away, on the same half-inch line, were multiple fill lines for chemical tanks. One of the more notable chemicals was hydrochloric acid.
“Upon closer inspection I found that there were hoses attached, presumably to stop spillage, to the tank fill lines,” continued Skagen. “Not only were these hoses too long to provide a sufficient air gap between each outlet and tank, but the hoses were long enough to go directly into the tanks and potentially become submerged in the chemicals. There was no form of backflow prevention present, such as a reduced pressure (RP) or double check valve assembly (DCVA), on the water line or at the chemical tank fill lines.
“Considering this improper plumbing arrangement, if one of the hoses became submerged in one of the chemical tanks, and the eyewash station, immediately downstream from the chemical tanks, was turned on and used, a venturi effect could be created from the sudden pressure drop. As a result, the chemical would be drawn into the pipe to the eyewash station, and into the eyes of the person using the eyewash station,” he noted.
“To correct this potential cross connection, I separated the water lines, removed the hoses and installed both an RP and DCVA device to isolate the tank fill. I believe this situation highlights the need for backflow prevention programs and education on the dangers of cross connections,” concluded Skagen.
Both winners received a test kit supplied by Zurn Canada.

BACK TO BASICS: Why traditional media matters for mechanical industry pros
In a world obsessed with digital-first marketing strategies, traditional media often gets overlooked. Yet for HVAC professionals, the time-tested approaches of press releases, local newspapers, and radio or television can offer a unique opportunity to connect with customers on a more personal and trusted level. Business owners often seek straightforward, effective strategies − ones that align with their communityfocused values. This back-to-basics approach can help HVAC pros cut through the noise, build trust, and drive business growth.
A back-to-basics approach to marketing can help mechanical contractors build trust with customers.
Don’t shy away from traditional media
Don’t let misconceptions about traditional media hold you back. Here’s why it’s still worth your attention:
Why traditional media works
Think about it − when was the last time you felt truly connected to an online ad? Probably not often. Traditional media, on the other hand, has a secret weapon: trust.
People are more likely to believe what they see in their local newspaper or hear on their favourite radio station. If your HVAC business is mentioned in these spaces, it immediately positions you as reliable and credible − something digital ads can struggle to achieve on their own.
Paul Bies
• It’s more affordable than you think: Local newspapers, radio ads, and magazines are often budget-friendly, especially in smaller markets. Bundled deals that combine ads with editorial coverage give you even more value.
• It sticks around: Unlike digital ads that disappear when your budget runs out, a print article or advertorial can be read and shared for weeks or even months.
• It’s highly targeted: Traditional media focuses on specific geographic areas, making it perfect for HVAC businesses that rely on local customers.
Pro Tip: Reach out to local media reps to learn about package deals. Many publications offer bundled advertising and editorial opportunities that give you great exposure.
Paul Bies, co-founder and president of Mystique Brand Communications (mystique.ca) in Toronto, ON, brings a wealth of marketing expertise to his role as Mechanical Business marketing columnist. His mission is to empower businesses and to share insights that provide valuable perspectives for their success. As the son of an HVAC entrepreneur, he understands the business landscape and is committed to helping MB readers thrive.
Don’t
forget direct mail
Direct mail might not sound as exciting as a digital campaign, but it’s incredibly effective. Picture this: A postcard lands on a homeowner’s kitchen counter, reminding them to schedule their winter tune-up just as temperatures start to drop.
Direct mail works especially well when:
• It includes a limited-time offer, such as a discount on seasonal maintenance.
• You target specific neighbourhoods or demographics.
• The message ties into other media campaigns, such as radio ads or online promotions.
When done right, direct mail becomes a tangible reminder that puts you ahead of the competition.
Make your message newsworthy
Not every press release gets picked up by local media, so you’ve got to make yours stand out. Think about what would grab your attention as a homeowner.
When crafting a press release, focus on providing value. Could you share helpful data, such as how seasonal maintenance saves homeowners money? Or highlight a community initiative, such as offering free tune-ups for seniors?
Combine traditional and digital strategies
Here’s where things get interesting: Traditional media works best when it’s paired with digital. Studies show that most people need to see your message seven or eight times before they act. By combining traditional and digital efforts, you create a powerful, integrated strategy that ensures you’re reaching homeowners wherever they are.
How you can do it:
1
The more relevant and helpful your message, the better your chances of getting noticed.
Get in front of local readers
Local newspapers and magazines are your gateway to connecting with homeowners, and here’s an insider tip: When you buy ad space, many publications offer editorial or advertorial opportunities as part of the deal. In addition, editors are often looking for unique content so it is worthwhile to send in short, timely articles with your byline. Avoid the hard sell – concise and generic information will enhance your credibility.
Imagine running a piece called “5 Easy Ways to Lower Heating Costs This Winter,” paired with an ad for your seasonal tuneup services. It’s a win-win: You educate readers while subtly positioning your business as the go-to provider.
Pro Tip: Build relationships with your local print media’s editorial team. They’ll often let you know about seasonal opportunities to get featured, such as homeowner guides or special issues.
2 3
Share traditional media mentions such as newspaper articles or radio spots on your social media pages and email newsletters to expand their reach.
Use retargeting ads to remind people about your services after they’ve seen or heard traditional ads.
Keep your messaging consistent across all platforms. Whether it’s a radio ad or an Instagram post, your tone and message should match.
This integrated approach keeps your business top of mind and builds trust with potential customers, no matter where they encounter your brand.
Wrapping it up
Traditional media might not seem flashy, but it’s one of the most reliable ways to build trust and connect with your community. Whether it’s a well-placed press release, a radio ad, or a direct mail campaign, these strategies work − especially when combined with your digital efforts. Don’t overlook the power of going back to basics. By using traditional media to amplify your message, you can position your HVAC business as the provider homeowners turn to when it matters most.
Many contractors have informative material on hand that could easily be circulated to local media outlets.
