■■Engineering Regulations and Guidelines

The following regulations and guidelines must be observed:

Space requirements

• see separate data sheet.

• Hoval’s technical information and installation instructions.

• New and if applicable existing installations need to be adequately cleaned and flushed before being filled. The boiler may only be filled after the heating system has been flushed!

• Hoval’s hydraulic and technical control regulations.

• Parts of the boiler which are in contact with water are made of ferrous materials.

Buffer Storage Unit Selection

• Local building law

• On account of the danger of stress cracking corrosion the chloride, nitrate and sulphate contents of the heating water must not ex ceed 200 mg/l in total.

AgroLyt® storage unit volume * type minimum dm3

• Fire protection standard • DVGW guidelines

• The pH value of the heating water should lie between 8,3 and 9,5 after 6 -12 weeks of heating operation.

• DIN EN 12828 Heating systems in buildings - Design of hot water systems. • DIN EN 12831 Heating systems in buildings - Procedure for calculation of the standard heating capacity • VDE 0100

Water quality

Heating water • The European Standard EN 14868 and the Directive VDI 2035 must be observed. • Hoval boilers and calorifiers are designed for heating plants without significant oxygen intake (plant type I according to EN 14868). • Plants with -- continuous oxygen intake (e.g. underfloor heating systems without diffusion proof plastic piping) or - intermittent oxygen intake (e.g. where frequent refilling is necessary) must be equipped with separate circuits. • Treated heating water must be tested at least 1 x yearly. According to the inhibitor manufacturer‘s instructions, more frequent testing may be necessary. • A refilling is not necessary if the quality of the heating water in existing installations (e.g. exchange of boiler) conforms to VDI 2035. The Directive VDI 2035 applies equally to the replacement water.

• The suction ventilator must be easily accessible (for the purpose of dismantling it).

Recommended minimum storage unit size

(20) 1000 (25) 1500 (35) 2000 (50) 3000 * Basic specifications: Heating return flow temperature at -10°C outside temperature maximum 40°C, heating flow temperature 85°C, 50% of the filling quantity is taken up by the storage unit.

• In order to maintain a high level of boiler efficiency and to avoid overheating of the heating surfaces the values given in the table should not be exceeded (dependent on boiler performance ratings - for multi-boiler plants rating of smallest boiler applies - and on the water content of the plant). • The total amount of filling and replacement water which is used throughout the total ser vice life of the boiler must not exceed three times the water capacity of the plant.

Boiler room

• The boiler room must comply with fire regu lations. • The combustion air supply must be guaranteed. The air opening should be in the lee of the prevailing wind direction and may not be shuttered in any way. The minimum free opening cross-section is 200 cm2.

Qh = Heating requirement at -10 °C outside temperature

°C = The daily heating requirement can be met when at least this outside temperature prevails. Basis for calculation: Firing with deciduous wood, filling quantity in kWh x 0,8, requirement per day = 14 x Qh.

Installation Buffer storage unit and return flow safeguard • For the Hoval AgroLyt® a buffer storage unit with automatic storage and charging control and boiler return flow control must be instal led.

Thermal Process Control

• If a pressurised expansion chamber is instal led then a thermal process controller must also be installed (in accordance with. SWKI regulation 93-1).

Hydraulic switching • Please observe the examples for use. Heat distribution • For central heating of rooms an automatic temperature regulator with one or more mixing circuits should be installed. Plant with open expansion chamber • The height of the plant must be such that at least the required minimum pressure in the suction pipe of the pump is maintained in order to prevent cavitation (see heading ‘circulation pumps - pumps’) Plant with pressurised expansion chamber • In accordance with the SWKI regulation 93-1 pressurised expansion chambers are only permissible in combination with a thermal process controller consisting of an integrated heat exchanger in the boiler together with a thermal discharge valve.

≥ 2 bar

• The thermal process control must be con nected to the cold water supply. The mini mum required flow pressure is 2 bar. Minimum throughput: AgroLyt® (20) = 1500 l/h (25) = 1500 l/h (35) = 2000 l/h (50) = 2000 l/h. • The cleaning aperture for the connector (top of boiler) must remain easily accessible. In stall water pipes vertically upwards.

Safety valve • A safety valve with an automatic air vent must be installed at the connector for the safety group. 16

■■Engineering Chimney / Flue System

Connecting pipe • Feed the flue pipe connecting increasing between the heating boiler and the chimney with a gradient of 30-45° into the chimney, if possible. • For a pipe longer than 1 m thermal insulation is necessary. • The connecting pipe must be introduced into the chimney in such a way that no condensate can flow into the heating boiler. • The connecting pipe must contain a circular, closable flue gas measurement aperture with an inner diameter of 10-21 mm. The aperture must be accessible through the thermal insulation if present. Position:

2xD D

Chimney • The Agrolyt® must be connected to a chimney (flue gas temperature > 200 °C). • The effective height of the chimney must be at least 6 m. • The chimney outlet should be higher than the roof ridge. • The flue gas ducts must be capable of withstanding humidity, acidity and soot combustion and be approved for flue gas temperatures > 160 °C. • Existing chimneys must be renovated ac cording to the instructions of a chimney constructor. • Determination of the flue gas duct crosssection in accordance with EN 13384 Part 1 and 2 • A flue gas thermometer (included with the AgroLyt®) must be installed in the connec ting pipe. This is necessary in order to main tain a high level of plant efficiency. • An auxiliary air flap as chimney damper con trol is recommended.

D Required draught • In calculating the chimney dimensions the chimney draught should be between 0,1 and 0,25 mbar (10-25 Pa). • To reliably prevent the occurrence of excessive flue draught, it is essential to install a damper. The damper ensures a constant flue draught, protection of the heating equip ment, effective ventilation of the flue and optimum energy utilisation. This is the only reliable way to protect the boiler against ac cidental overload.

Non-binding standard values for chimney cross-sections Basic specifications: smooth walled chimneys made of chrome steel piping connecting pipe ≤ 2.5 m, 1 bend 90° and 1 angle piece 45°, Σζ = 1,0. connecting pipe and heating boiler flue outlet should have the same cross-section; connecting pipe and chimney should be thermally insulated. Height above sea level ≤ 1000 m, outside temperature -15 °C.

Fuel

• air-dried, untreated log wood such as split logs, billets or roundwood. max. Ø 15 cm guidelines for dry storage: softwood 1 to 1½ years hardwood 2 to 2½ years • untreated coarse wood chips (humidity < 30 %) including attached bark with length ≥ 5 cm, in combination with 50 % split wood (thus the proportion of coarse chips can be approx. 50 % according to quality). • Pressed chips, shavings etc with diameter ≥ 8 cm, provided they are not produced with the use of bonding agents, in combination with 50 % split wood (thus the proportion of pressed wood can be approx. 50 % according to quality). • Carpentry waste in the form of bonded wood providing this is free from wood protection agents. Size ≥ 5 cm, in combination with 50 % split wood (thus the proportion of carpentry waste can be approx. 50 % according to quality). Fuels which may not be used - coke, coal - sawdust - plastic-coated waste wood - treated or painted wood - plastic - waste The burning of waste, of wood treated with wood preservatives or with a coating consisting of halogenated organic compounds is prohibited.

■■Engineering Damper and explosion damper

The installation of a damper with deflagration flap (explosion damper) is mandatory.

Flue gas system

A moisture-resistant chimney is required. Draughting requirement 10 Pa. Route the connecting line (flue gas pipe) with an upward slope, maximum length 3 m. Provide thermal insulation of at least 30 mm for the flue gas pipe. Where possible, flue connection 45°. Do not wall in the flue gas pipe directly, but integrate it flexibly to avoid noise transmission. The flue gas pipe must be integrated in the flue gas duct in such a way that condensation cannot flow into the boiler.

Buffer storage tank

A small buffer storage tank optimises the operation of a pellet heating system and is recommended. For over-dimensioned boilers (≥ 50 %) or in those cases where parts of the heat supply system are frequently disconnected or in the case of high passive solar input, a buffer storage tank is mandatory. Selection of a buffer storage tank Recommended minimum tank size at a nominal load less than 70% of the boiler nominal load or high passive solar input. BioLyt Type

Water quality

Heating water: • ÖNORM H5195, European Standard EN 14868 and VDI Guideline 2035 must be complied with. • Hoval boilers and calorifiers are suitable for heating systems without significant oxygen intake (system type I in accordance with EN 14868). • Systems with - continuous oxygen intake (e.g. underfloor heating systems without diffusionproof plastic piping) or - intermittent oxygen intake (e.g. frequent topping-up required) must be equipped with separate circuits. • Treated heating water must be tested at least 1x per year, or more frequently if prescribed by the manufacturer of the inhibitor. • On existing systems (for example if the boiler is replaced), where the quality of the existing heating water meets the requirements of VDI 2035, re-filling of the system is not recommended. The requirements of VDI 2035 also apply to replacement water. • Before filling new systems and, where necessary, existing systems, the heating system must be professionally cleaned and flushed! The boiler must not be filled until the heating system has been flushed. • All parts of the boiler which come into contact with water are made of ferrous materials and stainless steel.

In many cases, a buffer storage tank is necessary for water heating or integration of a solar energy system. Recommended capacity: 10-30 litres/kW boiler output plus volume for water heating and solar energy system. Detailed dimensioning of the system is necessary.

• Due to the danger of stress corrosion, the sum of the chloride, nitrate and sulphate contents of the heating water must not ex ceed a total of 50 mg/l (ÖNORM H5195 stip ulates that the limit value for chlorides is 30 mg/l).

Return temperature control

• The pH-value of the heating water should be between 8.3 and 9.5 after 6-12 weeks of heating operation.

• Please observe the hydraulic example appli cations.

Filling and replacement water: • As a rule, untreated drinking water is best suited as filling and replacement water for a system with Hoval boilers. However, the quality of the untreated drinking water must still meet the requirements of VDI 2035 or be demineralised and/or treated with inhibitors. The requirements of EN 14868 must be met in this context. • To maintain high boiler efficiency and prevent overheating of the heating surfaces, the values in Table 1 should not be exceeded, taking into consideration the boiler output (smallest individual boiler in multi-boiler plants) and the water content. • The total quantity of filling and replacement water added to the boiler over its service life must not be higher than twice the system water content.

Combustion air supply

An adequate combustion air supply is a prere quisite for safe and economical operation. Free supply air cross-section at least 200 cm2. It is very important to ensure that the combustion air is clean and free from halogen compounds. These are present, for example, in spray cans, varnishes, glues, solvents and cleansing agents.

Electrical connection

The boiler is only suitable for installation in dry rooms (protection rating IP 10). Installation must be performed by an authorised electrician and in accordance with local regulations! Electrical connection: 230 V, 50 Hz, min. 16 A slow-blow. Caution: Connect phases correctly! An omnipolar main switch with a minimum contact spacing of 3 mm must be installed on-site, outside the boiler room.

Installation instructions

Please observe the installation instructions supplied with every boiler. Pellet storage systems see separate brochure

■■Engineering Flue gas system

A moisture-resistant duct is required. Draughting requirement 5 Pa. Route the connecting line (flue gas pipe) with an upward slope, maximum length 3 m. Provide heat insulation of at least 30 mm for the flue gas pipe. Where possible, flue connection 45°. Do not wall in the flue gas pipe directly, but integrate it flexi bly to avoid noise transmission. The flue gas pipe must be integrated in the flue gas duct in such a way that condensation cannot flow into the boiler.

Space requirements

see separate dimensioned drawing.

Boiler selection

• The boiler performance must at least cover the hourly heating capacity demand of the building. • The boiler must be selected taking account of the filling periods (see technical data).

Energy storage device

The installation of an energy storage is generally recommended. For oversized boilers (≥ 20 %) or if parts of the heat diffusion system are often disconnected, a storage tank is im perative. For hot water generation a storage tank is necessary in most cases. Standard size: 10-30 litre/kW boiler output. An accurate determination of the plant dimensioning is necessary. In the case of the buffer storage tank, it is important to ensure correct dimensioning of the connection nozzles (they should not be too small).

Return temperature control

A return temperature control must be installed to ensure a minimum boiler return flow temperature of 45 °C. Observe the hydraulic example applications.

Thermal safety drain

Use drain funnels, as drainage must be visible for inspection purposes. Required minimum connection pressure 2 bar.

Water quality

The European Standard EN 14868 and the Directive VDI 2035 must be observed. • Hoval boilers and calorifiers are designed for heating plants without significant oxygen intake (plant type I according to EN 14868) • Plants with -- continuous oxygen intake (e.g. underfloor heating systems without diffusion proof plastic piping) or -- intermittent oxygen intake (e.g. where fre quent refilling is necessary) must be equipped with separate circuits. • Treated heating water must be tested at least 1 x yearly. According to the inhibitor manufacturer‘s instructions, more frequent testing may be necessary. • A refilling is not necessary if the quality of the heating water in existing installations (e.g. exchange of boiler) conforms to VDI 2035. The Directive VDI 2035 applies equally to the replacement water. • New and if applicable existing installations need to be adequately cleaned and flushed before being filled. The boiler may only be filled after the heating system has been flushed! • Parts of the boiler which have contact with water are made of ferrous materials. • On account of the danger of stress cracking corrosion the chloride, nitrate and sulphate contents of the heating water must not exceed 200 mg/l in total. • The pH value of the heating water should lie between 8.3 and 9.5 after 6 -12 weeks of heating operation.

Filling and replacement water: • For a plant using Hoval boilers untreated drinking water is generally best suited as heating medium, i.e. as filling and replace ment water. However, the water quality of the untreated drinking water must fulfil the standard set in VDI 2035. Should the mains water available not be suited for use then it must be desalinated and/ or be treated with inhibitors. The stipulations of EN 14868 must be observed. • In order to maintain a high level of boiler efficiency and to avoid overheating of the heating surfaces the values given in the table should not be exceeded (dependent on boiler performance ratings - for multi-boiler plants rating of smallest boiler applies - and on the water content of the plant). • The total amount of filling and replacement water which is used throughout the total ser vice life of the boiler must not exceed three times the water capacity of the plant.

Combustion air supply

An adequate combustion air supply is a prerequisite for safe and economical operation. It is very important to ensure that the combustion air is clean and free of halogen compounds. These are present, for example, in spray cans, varnishes, glues, solvents and cleansing agents.

Electrical connection

The boiler is only suitable for installation in dry rooms. Installation must be performed by an authorised electrician and in accordance with local regulations! Electrical connection: 230 V, 50 Hz, 13 A slow-blow. If a ZN6 set is being mounted a second supply line (230V/10A) must be provided. Warning: Connect phases correctly! An omnipolar main switch with a minimum contact spacing of 3 mm must be installed on-site, outside the boiler room.

Installation instructions

Please take note of the advice contained in the installation instructions supplied with every boiler.

■■Engineering Plant with open expansion tank • The height of the apparatus must ensure that the required minimum pressure in the intake connection of the pump for the avoid ance of cavitation is reached

Connecting pipe • The exhaust connecting pipe between the heating boiler and the flue must be connec ted to the flue either horizontally or with an incline of up to max. 60°C.

Non binding standard values for flue diameter The following are standard values: A precise calculation of the output capacity must take place.

System with pressure expansion tank Hoval BioLyt (50-160) • with built-in thermal safety drain. • Inspected according to EN 303-5. The expansion and safety-engineering equipment required for the heating system must be dimensioned and installed outside the boiler in accordance with recognised engineering practices.

• If the length is greater than 1m insulation is required.

Fundamentals: Smooth wall flues made of chrome steel pipe connecting pipe ≤ 2.5 m with 0,5 m taper, 1 curve 90° and 1 angle 45°, Σζ = 0,8. Connecting pipe of same Ø as exhaust connections of heating boiler, connecting pipe and flue with insulation 40 mm. Height above sea level up to maximum 1000 m, external temperature -15 °C.

Safety valve A safety valve and an automatic air bleeder must be installed on the flow.

The fitting of the connecting pipe to the flue must be carried out in such a way that no condensation water can flow into the heating boiler. Do not directly wall in exhaust pipe but connect it flexibly so that transmission of noise can be avoided. Position:

• A lockable exhaust measuring nozzle with internal diameter of 10-21mm must be instal led in the connecting pipe. The nozzle must be directed outwards via the insulation. Flue plant • BioLyt downward pressure: min. 0.05 mbar • The exhaust plant must be unaffected by moisture, acid resistant, emission burn resi stant and suitable for exhaust temperatures of 70-160 °C. • With existing flue installations, the cleaning must take place according to information from the chimney builder. • Pay attention to SIA recommendation Num ber 384/4 „Chimneys for building heating, cross section identification”. • Unfavourable wind conditions can create areas of negative pressure at the building roof, by which the flue gas can be blown back into the chimney outlet. In order to prevent this we recommend to mount the chimney outlet at least 0,5 meters above the pediment (or 2 meters above slanted/saddle roofs) or 2 meters above the roof (flat roof). (Please observe the regional rules as well.)

Connection of 2 Hoval BioLyt (50,70) to a common chimney In principle, the separate connection of 2 in dependent chimneys is always the better so lution. If this is not possible, the following criteria must be fulfiled when connecting 2 Hoval pellet boilers of the series BioLyt (50,70) to a common chimney: • A chimney calculation must exist as fulfilled, which evaulates all relevant conditions (above all, minimum draught need); to be observed is (among other things) the greatly increased modulation area of a 2-boiler system. • A separate connection pipe must be run to the chimney from both pellet boilers; both flue gas pipes may first meet in the vertical chimney (intersection each with 45°); a junction before entry in the chimney per hose piece or similar is not permitted. • Every connection pipe must be equipped with its own combination door – damper protection/explosion protection; Distance from the exhaust gas outlet of the boiler must amount to at least 2 x D. • When commissioning the boiler, the correct function of the exhaust system must be checked and confirmed by Hoval factory customer service (according to internal in spection certificate). • The approval of the responsible regional chimney sweeper must be present.

Hoval storage facility for pellets

■■Description Pellets storage room with inclined floor The term ‘storage room’ is used to indicate a room specifically used for the storage of pellets. In existing buildings an oil storage room can be converted into a pellets storage room. The storage room must be dry as pellets swell up if humidity is too high and consequently their quality may be impaired. If storage rooms present an increased air humidity the pellets should be stored in the fabric silo. The storage room must additionally be absolutely tight and its walls must be solid. The storage room must be equipped with the corresponding components necessary for the filling procedure by the tanker.

Notice: Pellets storage rooms must be cleaned regularly (approx. every 2-3 years) and the residual sawdust must be removed!

Extraction system: different options for the storage room Suction system with 3 suction outlets only for Hoval BioLyt (8-36) • For storage rooms with up to approx. 20 m3 content.

Suction system with 4 suction outlets only for Hoval BioLyt (8-36) • For storage rooms with up to approx. 20 m3 content.

Suction system with screw extraction for Hoval BioLyt (8-36, 50-160) • For small, longish storage rooms with more than 20 m3 content.

Suction system with mole for Hoval BioLyt (8-36,50,70) • mole system for max. working floor area 2,5 m x 2,5 m and height 1,9 - 2,5 m comprising: -- Mole 230 V for integration into the boiler suction system -- 5 m antistatic flexible hose with rubber electric cable (explosion-proof) -- Adapter plate for storage room wall duct with vacuum and return air connectors -- Manual rope pull

■■Engineering Pellets as fuel

Characteristics Wood pellets are pressed cylinders of dry, un treated waste wood (sawdust and shavings). They have a diameter of about 6 mm and a length of 30 - 50 mm and display the following advantages: - homogeneity - low humidity - maximum approx. 10 % - high and constant heating value (approx. 5 kWh/kg) - low transport and storage volume thanks to the high energy density (3-4 x less volume than wood chips) - easily poured and transported to combustion chamber - can be finely dosed - simple automatic ignition possible

Fuel data calorific value Hu = 5 kWh/kg raw density = 1200 kg/m3 pouring density = 650 kg/m3 energy density = 3200 kWh/m3

What are the characteristics of good quality pellets? - uniform size - low dust generation - smooth, polished surface - no longitudinal cracks Pellet suppliers A supplier list can be obtained on request or at www.holzenergie.ch

Conversion 2 kg pellets = approx. 1 litre Diesel Oil 1 m3 pellets = approx. 330 litres Diesel Oil 1 tonne Pellets = approx. 1,5 Sm3 (after loose pouring) = approx. 500 litres Diesel Oil = approx. 5000 kWh

Hoval storage facility for pellets

■■Engineering Storage room for pellets Pellets Box (reservoir) • There is a reservoir integrated into the boiler. • The conveyor screw installed in the boiler transports the pellets from the reservoir to the burner. Extraction System (automatic pellets supply) • An automatic supply system is mounted on the reservoir. • distance of supply unit (boiler) unit to furthest suction inlet. • maximum transport distance:

1,8 2,8 4,5

* The transport distance means the dis tance from the suction outlet/suction screw to the top edge of the boiler resp. from the bottom of the silo or earth tank to the upper edge of the boiler.

Location of the boiler room and the pellets-storage room • The pellets are delivered by tanker and air blown into the storage room whilst the ex haust air is recaptured. • The tankers have a pumping hose which is a maximum of approx. 30 m long, therefore the pellets storage room (i.e. the filling couplings) must be less than 30 m from the closest point where the tanker can park. • Before the new pellets are introduced the heating system should be properly shut down. Notices indicating this should be plac ed at the filling point and in the boiler room. • If possible the pellets storage room should have an outside wall as the filling point must be accessible from the outside. • If the storage room has no outside wall then the transport pipes must be extended to a suitable outlet (observe fire regulations). • The boiler room should also have an outside wall which allows for direct ventilation. • If this is not possible then a ventilation pipe with (5 cm2/kW but with a minimum of 200 cm2 ) cross section must be laid to the outside wall. Requirements for storage room: • absolutely dry, dust proof and free from for eign objects (cleared and swept) • walls and ceiling must be massive and fire resistant (REI90 / F90). • fire protection door (T30) which opens outwards with seal and wooden boards in Z profile (see accessories) • no open installations, especially no electrical installations. Essential electrical installations must be protected from explosion and carried out according to current regulations. • After the extraction system has been instal led inclined flooring (approx. 45°) is to be installed laterally with sufficiently stable support constructions. The pellets weigh approx 1700 kg/m2 at a storage level of 2,5 m.

Filling couplings Pellets storage

room

max. 30 m

• For introduction and extraction 2 couplings using Storz A 110 cover system (see accessories) are necessary. To be installed 20 cm below the ceiling approx.50-100 cm apart, if possible in the narrower wall of the storage room. • The connecting sections and ducts should be metal and secured against static charging (earthed). • The inlet and outlet connectors are to be clearly and permanently marked as such. • Filling and extraction ducts which are led through neighbouring rooms must be clad with fire resistant material (requirements of fire category L90). • A baffle is to be installed opposite the entry so that the wall is protected during filling and the pellets do not get damaged (see accessories). • Where suction inlets are used (BioLyt 8-36): Irrespective of the room size 3 or 4 inlets should be installed.

Tanker

max. possible transport height * [m]

• The inlet pipe must consist of one piece, whereas the return air pipe can consist of more than one section. Exception: pipe bend in the inlet pipe (connectors should be metal and electrically earthed). • The hoses at the switchover unit must be moveable. The switchover unit rotates through 180° or moves in a linear direction (depending on design).

Pellets

transport distance [m]

Forwarding and return air pipes • Only materials supplied by Hoval may be used. • Lay pipes as level as possible, without any dead ends, minimum bend radius 30 cm. If the minimum bending radius cannot be complied with, a corresponding pipe elbow must be used. • Do not lay the pipes outside. The pipes are not UV resistant and should not be exposed to temperatures above 60 °C. • Protect pipes from damage, e.g. from being trodden on.

• There is no minimum spacing required for the suction inlets. • For filling, i.e. for the suction device of the storage container the pellets tanker requires a 230 V, min. 16 A socket. This should be situated close to the filling inlet if possible, but under no circumstances in the storage room itself. • The storage room must be adequately ventilated. In the case of storage rooms of up to 10 t and filling lines of not more than 2 m in length, ventilation via the covers is sufficient.Vented covers, each with at least 20 cm2 free ventilation cross-section, must be fitted on the filling air and extraction connections. (Only permissible if the connections are routed into the open air.) • See VDI 3464 for the specifications for ventilation of a storage room with a capacity of more than 10 t or filling lines more than 2 m long.

■■Engineering Safety notes

Entering the pellet storage room or storage tank Under unfavourable circumstances, it may oc cur that an increased concentration of harm ful gases (such as carbon monoxide) arises in pellet storage rooms, possibly posing a risk when accumulating over a longer period of time. Despite the fact that under normal cir cumstances, there is no risk at all, one cannot rule out the possibility of such a scenario to occur. • If work is being carried out in filled storage rooms, a second person must always be present outside the room for security reasons. • Before entering the pellet storage room, it must always be thoroughly aerated. The storage room must be ventilated for at least 15 minutes. In the case of pellet storage rooms with a volume of more than 10 t, the duration of ventilation must be extended or mechanical ventilation provided. • No-one should enter the storage room in the four weeks following filling. If it is necessary for persons to enter the storage room, the room must be ventilated for at least 2 hours before entering. • It must be ensured that the storage room door remains open while there are persons inside the storage room. • Entering fuel storage rooms that have not been aerated (particularly underground tanks) must be avoided, only trained personnel is permitted to do so. Before entering the room or tank, the concentration of CO must be measured (the concentration must be less than 30 ppm). If necessary, thoroughly aerate the storage room or tank before entering it. • It the storage is difficult to access or if it is accessible only from above (such as underground tanks), the person entering the tank must be additionally secured. • Keep away children from the pellet storage place! • If there are moving parts (screw conveyors) in the storage room, turn off the mains switch of the heating system before entering the storage room, as otherwise there is a risk of injury. • Smoking, naked flames and other possible sources of ignition are prohibited inside the storage room.

Hoval fabric tank for pellets

■■Engineering Fabric silo for pellets Scope of use The fabric silo may only be used for storage of wood pellets according to EN 14961-2 resp. EN plus. Selecting the silo size Ideally the silo should accommodate a year’s supply of pellets. • Guide value pellets consumption: 400-500 kg per kW heating load • The selection is based on the available space (floor area, height). Installation room Depending on the local regulations storage containers of pellets can be maintained: • In a separate, fire resistant storage room (F90) or • directly in the boiler room with a minimum distance of 1 m to the boiler. The minimum clearance may be fallen below if a non-combustible heat protection or radiation plate is attached between the silo and the boiler. Note Observe the brochure „Recommendation for storing wood pellets“ at www.depv.de. The following distances must be complied with between the silo frame and walls for the rear ventilation, for protection against mechanical damage and for the accessibility when filling: Wall clearances: Frame dimension + at least 100 mm; for the filling side at least 800 mm

Access The room where the container is installed should be secured against improper access (e.g. children and pets). Set-up area The floor must be capable of bearing the load. Observe the point loading at the support legs! Special care should be taken with layered floors, e.g. concrete - thermal insulation screed! Floor: level and dry Placement out of doors As well as the requirements noted, the following should be observed: • Protection from rain, snow, humidity and di rect sunlight (container must be boarded on all sides). • Locally applicable fire regulations (minimum distances, fire protection zones). Filling The fabric silo can be filled directly from the tanker by installing a filling hose. For easier filling the filling and suction connectors can also be mounted on the outside wall. To this end the ducts to the fabric tank must be extended, fixed and earthed on site. (see accessories)

The fabric may not have contact with the walls nor with sharp or pointed objects.

15 bis 25 10 bis 15 5 bis 10

Moist side walls are permitted if the set-up room is ventilated and if ceiling as well as set up surfaces are dry.

The connecting sections and ducts should be metal and secured against static charging. The connection on the potential equalisation must be earthed. Filling ducts which are led through rooms where there is an increased danger of fire (garage, boiler room) must be clad with fire resistant material (requirements of fire category L90). Installation instructions Please note the contents of the installation instructions.

Extraction system (automatic pellet supply) Only pipes supplied by Hoval may be used. transport length [m]

The fabric must be protected from direct sun light.

Delivery of pellets with the tanker When positioning the couplings it should be noted that the pipe length between the tanker and the pellets inlet can be a maximum of 30 m. Before the new pellets are introduced the heating system should be properly shut down. Notices indicating this should be placed at the filling point and in the boiler room.

Filling pressure The filling pressure should amount to between 0,3 bar (approx. 10 m hose length) and 0,6 bar (approx. 30 m hose length). The max. filling pressure may not exceed 0,8 bar.

Ceiling clearance: Frame dimension + at least 200 mm

To protect the cover fabric of the silo during filling, there must be no pointed or sharp edges on the room ceiling.

Fire protection sleeves Fire protection sleeves are required for the wall feedthroughs of the hoses in the boiler room. If the hoses are run through intermediate rooms, additional fire protection sleeves RAS 29 (see accessories) are necessary on the out side of the wall of the storage room.

max. possible transport height [m] 1,8 2,8 4,5

• Lay pipes as level as possible, without any dead ends, minimum bend radius 30 cm. Protect from sunlight and exposure to tem peratures above 60 °C. • Do not use more than one section for the input pipe. • All pipes must be earthed at both ends.

Room ventilation A ventilation opening of min. 200 cm2, non- lockable, is required to prevent a dangerous CO concentration in the installation room, and to allow the transport air to escape into the at mosphere during the filling procedure. The blown-in air escapes through the cover fabric of the silo. Thus, no extraction of the blown-in air is necessary during filling of the silo.

The buyer shall inform us immediately of any pledge or other impediment to our property enforced by third parties. The buyer shall be obliged to collaborate in measures required to protect our title. He/it shall, in particular, empower us upon the conclusion of the contract to make entries or prior notice of the reservation of title at his/its cost in public registers, books and documents, etc., in accordance with the relevant national laws and shall perform all formalities in this respect. The buyer shall maintain the reserved goods at his/its cost for the duration of the reservation of title and shall insure the said goods against theft, breakage, fire, water and other risks in our favour. He/it shall also take all steps to ensure that our property claims are neither adversely affected nor rescinded. Delivery periods Delivery periods and deadlines stated by us shall be approximate unless we have given an express written confirmation of a deadline as binding. Delivery periods shall be deemed to have been met if notification of readiness to deliver has been sent to the buyer before the end of the delivery period. The delivery period shall be prolonged if details required for the performance of the contract are not received on time or if they are subsequently changed by the buyer. The delivery period shall also be reasonably prolonged if impediments arise which we cannot avert despite exercise of the necessary care (e.g. major operational disruptions, industrial disputes, delayed or defective deliveries, force majeure, etc.). If an agreed delivery date is met by more than 14 days, the buyer shall be obliged to set us a reasonable period of grace. The buyer may only withdraw from the contract if our goods have not been delivered by the end of the said period of grace. Compensation claims for non-performance, delayed performance or any consequential losses shall be excluded unless there was gross negligence on our part. Transfer of risk Unless expressly agreed otherwise in writing, our â&#x20AC;&#x17E;ex worksâ&#x20AC;&#x153; deliveries shall be made in accordance with the international rules on the interpretation of commercial clauses of the International Chamber of Commerce (Incoterms) in the version in force on the date of the order confirmation. The transfer of risk shall be determined by the aforesaid Incoterms. 73

Standard terms and conditions of delivery

8.3 8.4 8.5

Insurance against damages of any kind shall be the responsibility of the buyer. Complaints in connection with the transport shall be immediately notified by the buyer to the last carrier upon receipt of the delivery. If despatch is delayed at the request of the buyer or for any other reasons not attributable to us, the risk shall pass to the buyer on the original date envisaged for the „ex works“ delivery. We shall be entitled to demand payment from this date onwards.

9. Delivery inspection 9.1 The buyer shall be required to inspect deliveries immediately. If the goods do not comply with the order or the delivery note or if visible defects are identified, he/it shall be obliged to notify the aforesaid to us in writing within eight days of receipt. Later complaints shall not be recognised. (Re transport damages, cf. Section 8.4) 10. 10.1

10.2

Assembly and operations The assembly, putting into operation, operation and maintenance of the delivered goods shall be carried out in accordance with our guidelines. They may be executed by our staff or by appropriately trained third parties as agreed with the buyer. If we require a commissioning certificate for certain product groups, warranty claims for the proper functioning of the equipment can only be enforced if a proper hand-over has been documented by a confirmed commissioning certificate received by us within one month of the hand-over.

11. Warranty 11.1 Warranty period 11.1.1 The general warranty period shall be 12 months from the first commissioning but no longer than 18 months from the date on which the relevant goods left our works. If despatch is delayed for reasons not attributable to us, the warranty shall lapse no later than 18 months after notification of the readiness to deliver. The general warranty period shall exclude electrical components for which the warranty period shall be 6 months from the first commissioning but no later than 12 months from the date of shipment from our works. 11.1.2 We refer to Section 11.6.1 with regard to the warranty period for third party products. 11.1.3 The warranty period for components which we have repaired during the warranty period or have delivered as replacement shall be 12 months from the completion of our repair or from the date of the replacement delivery but no longer than the end of a period equivalent to twice the original warranty period as per Section 11.1.1. 11.2 Liability for material, design and workmanship defects 11.2.1 The contractual condition of the goods shall be based on the condition upon the transfer of risk. 11.2.2 Defects shall be notified to us immediately in writing. 11.2.3 We shall be liable for all components which can be shown to have become defective or unusable before the end of the warranty period as a result of defective materials, defective design or defective workmanship, with such components being repaired or replaced ex works immediately at our choice. 11.3 Liability for warranted qualities 11.3.1 Warranted qualities shall only be those which are specifically designated as such in the order confirmation or in the relevant specifications. 11.3.2 The aforesaid assurance shall apply at the latest until the end of the warranty period. If a taking-over test has been agreed with the buyer, the assurance shall be deemed as performed if proof of the relevant qualities is furnished during the aforesaid test. 11.3.3 If the warranted qualities are not performed or only partially performed, the buyer shall be entitled to an immediate rectification. The buyer shall grant us the necessary time and opportunity for this purpose. 11.3.4 If the rectification is abortive or only partially successful, the buyer shall be entitled to a reasonable reduction of the purchase price. If the defect is so serious that it cannot be rectified within a reasonable period of time, and if deliveries or services for the notified purpose are not usable or are only usable to a much lesser extent, the buyer

shall be entitled to refuse acceptance of the defective component or to withdraw from the contract if part-acceptance is economically unreasonable. We shall only be obliged to refund amounts which have been paid to us for the components affected by the aforesaid withdrawal. 11.4 Exclusion of liability for defects 11.4.1 Our liability shall exclude damages which cannot be proved to have been sustained as a result of defective material, defective design or defective workmanship. 11.4.2 Damages shall therefore be excluded for example which were caused by – improper work of other persons with regard to planning, site preparation, assembly, operation and maintenance; – plant concepts and designs which do not comply with the latest state of the art; – non-observance of our guidelines for planning, assembly, commissioning, operations and maintenance; – force majeure (e.g. thunderstorms). 11.4.3 The following shall be excluded in particular – corrosion damages (e.g. as a result of aggressive water, unsuitable water treatment, oxygen intakes, emptying the plant over a longer period of time, falling below the dew point, chemical or electrochemical effects, etc.); – damages caused by air pollution (e.g. the accumulation of intense dust, aggressive vapours, etc.); – damages caused by unsuitable equipment and fuels; – damages caused by overcharging, excessive water pressure, scaling, improper electrical connections and inadequate fuse protection. 11.4.4 Components shall also be excluded from the warranty which are subject to natural wear and tear (e.g. burner nozzles, combustion chamber inserts, ignition and monitoring components in contact with fire, fireclay and wall facings, fuses, seals and flexible tubes). 11.5 Commissioning certificate 11.5.1 We hereby draw attention to the due and proper hand-over and - if envisaged - the commissioning certificate in accordance with Section 10.2 as prerequisites for our warranty. 11.6 Deliveries and services of sub-contractors 11.6.1 Our liability for third party products which form a major part of the delivered goods (e.g. warehouse and conveying equipment, burners, measuring and control equipment, electrical components, flue gas and waste water cleaning equipment) shall - if permissible - be limited to an assignment of our claims against the suppliers of the said third party products. 12. Exclusion of further liability 12.1 The buyer shall have no rights and claims for materials, design and workmanship defects or the lack of warranted qualities unless specifically mentioned in Sections 11.1 to 11.6. 12.2 All claims for compensation, reduction in the contract price, rescission of the contract or withdrawal from the contract shall be excluded in particular unless these are specifically mentioned. Under no circumstances shall the buyer have any compensation claim for damages which were not sustained by the delivered goods themselves (e.g. replacement costs, cost for establishing the cause of the damage, expertises, production stoppages, production losses, lost orders, lost profit and other direct or indirect damages). The aforesaid liability exclusion shall not apply in the event of gross negligence on our part. 12.3 The exclusion as per Section 12.2 shall apply for all breaches of contract and all claims of the buyer regardless of why they were lodged from a legal point of view. It shall therefore also apply for a breach of any ancillary obligations (e.g. inadequate advice, etc.). 13. Jurisdiction 13.1 The place of jurisdiction for the buyer and for us shall be Vaduz. We shall be entitled to bring action against the buyer at his/its domicile, however. 13.2 The legal relationship between the parties shall be governed by the substantive laws of Switzerland. The application of the UN convention on contracts for the international sale of goods (CISG) shall be excluded.
