Boiler description

The ATAG iR is a room sealed condensing and modulating CH boiler for "open" expansion tank systems (open vent).

This boiler can also be used on a sealed system with an external expansion vessel and 3 bar pressure relief valve.

The boiler is equipped with a compact stainless steel heat exchanger with smooth pipes. It is a well thoughtout principle using sustainable materials.

The boiler burns natural gas to supply heat (LPG conversion kits available). This heat is transferred in the heat exchanger to the water in the CH installation. The rapid cooling off of the flue gases causes condensation. This results in a very high efficiency. The condensate that is formed, has no negative impact on the heat exchanger and it's operation, and is removed through the internal siphon. This feature requires a condensate drain pipe connected to the drain of the building

The boiler is equipped with an intelligent control system. The boiler anticipates on the heat demand of the heating installation or hot water demand. This will cause the boiler to tune its capacity to the installation. This means that the boiler will function longer and at a low level.

( F The boiler has been tested according to valid CE standards and has a CE certificate and >88% Efficient SEDBUK 2009.

Statement: No banned materials including asbestos, mercury, CFC's have or will not be included in the product.

Install the boiler in a boiler room in accordance to the actual local regulations BS5440-2:2009.

The installation location of the boiler has to be, and remain, frost-free. The boiler casing is splash water tight (IPX4D) and is suitable to be installed in e.g. a bathroom.

It is NOT necessary to have a purpose provided air vent in the room or internal space in which the boiler is installed. Neither is it necessary to ventilate a cupboard or compartment in which the boiler is installed, due to the extremely low surface temperature of the boiler casing during operation. Therefore the requirements of BS5440:2 may be disregarded.

The boiler can be mounted practically to any wall with the wall frame and the enclosed fixing equipment. The wall must be flat and of sufficient strength in order to be able to carry the boiler weight with its water content. Above the boiler there must be at least 210 mm working space in order to be able to fit a horizontal concentric flue system to the rear (See chapter 9.6 for more flue options). Make sure there is sufficient service space arround the boiler according figure 8.a. The location of the boiler can be determined by using the template.

The wall frame allows the possibity to pre-fit the complete heating system before fitting the boiler. Also the flue system can be prepared. Finally fitting of the flue system is done after fitting the boiler. See next page for all options for connection the heating, condensate, flue and gas installation.

Before hanging the boiler to the boiler frame remove the front panel of the boiler first. The front panel is also the air cabinet and is attached to the boiler case with 2 fasteners (A and B) (see figure 8.a).

Service dimensions (in mm)

See chapter 9.8 for further procedure to fit the boiler onto the boiler frame.

Page 13

8.1 Wall frame

  • Position the boiler frame against the wall using the template and a level.
  • Use the level for horizontal positioning and checking the vertical position.
  • Drill 4x ø10mm holes, 60mm deep
  • Press the nylon wall plug (ø10x55mm) in the holes
  • Mount the boiler frame to wall with the 4 coach screws (ø8x60mm) using a 13mm wrench

The boiler frame allows pipe work to be installed behind the boiler.

The pipe work must be installed at least 10mm inside the front of the frame.

The boiler has the following connection pipes;

  • The central heating pipes. The boiler is provided with isolation valves on the flow and return pipe to which the installation can be connected by means of 22mm compression fittings;
  • The gas pipe. The boiler is provided with an isolation gas valve to which the gas line can be fitted with 22mm compression fitting;
  • The condensation drain pipe. It consists of a 25mm flexible plastic pipe. The drain pipe can be connected to this by means of an open connection;
  • The flue gas exhaust system and air supply system. It consists of a concentric connection 60/100 mm.

See following chapters for detailed information regarding each connection.

It is advisable to clean all of the boiler's connecting pipes and/or to power flush the installation before connecting it to the boiler.

The boiler pipes can be connected to the installation by means of 22mm compression fittings. For connecting to thick-walled pipe (welded or fitted), adapters should be used.

Advice: ATAG Heating Technology Ltd recommend the installation of an in-line filter installed into the heating return as close to the boiler as possible. ATAG Heating Technology Ltd recommend the use of the:

ATAG iGuard Magnetic filter 22mm (Plastic) FC000100, (Brass) FC000200, 28mm (Brass) FC000250.

Additives in the installation water are only permitted in consultation with the country distributor. See chapter 9.2 for detailed information.

9.2 Water quality

Fill the installation with mains cold water.

In most cases, a heating system can be filled with water according to national standards for water and treatment of this water is not necessary.

In order to avoid problems with the CH-installations, the quality of the filling water has to meet the specifications mentioned in table 9.2.a:

If the filling water does not meet the required specifications, you are advised to treat the water to such an extent that it does meet the required specifications.

The warranty becomes invalid, if the installation is not being flushed and/or the quality of the filling water does not meet the specifications recommended by ATAG Heating Technology Ltd. Always contact ATAG Heating Technology Ltd in advance, if things are not clear or you wish to discuss any deviations. Without approval, the warranty becomes invalid.

Installation:

  • The use of groundwater, demi-water and distilled water is prohibited. (on the next page you will find an explanation of these definitions)
  • If the mains water quality meets the specifications mentioned in table 9.3.a, you can start flushing the installation before installing the device.
  • Whilst flushing, corrosion products (magnetite), fitting products, cutting oil and other undesirable products have to be removed.
  • Another possibility is to remove the pollution by installing a filter. The filter type has to fit the type and grain size of the pollution. ATAG Heating Technology Ltd recommends filter usage.
  • In this case, the whole piping system should be taken into consideration.
  • The CH-installation has to be properly vented before using the system. For that purpose, we refer to the commissioning chapter.
  • If a regular water top up is required (>5% on an annual basis), then there is a structural problem and an installer has to solve the problem. Regularly adding fresh water to the system also adds additional calcium and oxygen implying that magnetite and calcium residues can continue. The result may be blockages and/or leakages.
  • The use of anti-freeze and other additives requires periodical quality checks of the filling water in accordance with the period laid down by the additives supplier.
  • Chemical additions are to be avoided and should only be used after ATAG Heating Technology Ltd has approved their corresponding use.
  • Should you wish to achieve the required water quality by using chemical additives, then this is your own responsibility. The warranty on the product delivered by ATAG Heating Technology Ltd expires, if the water quality does not meet ATAG Heating Technology's specifications or the chemical additives have not been approved by ATAG Heating Technology Ltd.
  • On installation and during additions or changes at a later stage, ATAG Heating Technology Ltd recommends to keep a record of the type of water used, its quality at the time, and if applicable, which additives and quantities were added.

Softened water: Water with partly de-ionised calcium and magnesium.
Demi-water: Virtually completely demineralised water (very low conductivity)
Distilled water: Water no longer containing minerals.

9.3 Heating systems with plastic pipes

When connecting or using an underfloor heating system, designed with plastic pipes, or plastic pipes are used elsewhere in the installation, one should ensure that the plastic pipes used comply with the DIN 4726/4729 standard. It is set out in this standard that the pipes may not have oxygen permeability higher than 0.1 g/m3.d at 40°C. If the system does not comply with this DIN standard, the underfloor heating component will have to be separated from the central heating appliance by means of a plate exchanger.

No recourse can be made to the terms of the warranty in the event of failure to observe the regulations pertaining to plastic underfloor heating pipes.

Page 17

9.4 Gas connection in general

The local gas supplier should be consulted, at the installation planning stage, in order to establish the availability of an adequate supply of gas. An existing service pipe must NOT be used without prior consultation with the local gas supplier.

ATAG supplies boilers suitable for natural gas only and boilers for LPG only. Verify the identification plate on the boiler if the boiler is suitable for the gas kind on site. The boilers cannot be converted to another kind of gas.

Make sure that the gas pipe work does not contain dirt, particularly with new pipes.

The complete installation MUST be tested for gas tightness and purged as described in the above code.

The boiler connection is provided with an isolation valve with 22mm compression fitting, into which the gas line can be fitted.

Ensure that the pipework from the meter to the appliance is of adequate size. Do not use pipes of a smaller diameter than the boiler gas connection (22mm).

9.4.1 Natural gas connection (NG)

The gas supply must comply to the current Gas Safety, Installation & Use Regulations, in accordance with BS.6891.

The nominal inlet working gas pressure measured at the appliance should be 21 mbar +/- 2 mbar for Nat gas (G20). Allowing for the acceptable pressure loss of 1 mbar across the installation pipework, it can be assumed that a minimum permitted operating pressure of 18 mbar will be delivered to the inlet of the appliance. (Reference BS 6400-1 Clause 6.2 Pressure Absorption). When tested at the gas valve, the pressure drop from the meter to the gas valve must not be more than 4.0 mbar.

9.4.2 Propane gas connection (LPG)

The LPG installation must comply to the current Gas Safety, Installation & Use Regulations, in accordance with BS:6891.

Installing of a LPG installation should only be done by a registered LPG installer.

The tank must be provided with a high pressure regulator with a minimum capacity of 24 kg/h to reduce the tank pressure from 5 to 1.5 bar. The 1.5 bar high pressure gas line should have a minimum diameter of 15mm. In the high pressure gas line a house pressure regulator must be installed. When tested at the gas valve, the pressure drop from the pressure regulator to the gas valve must not be more than 2.5 mbar.

Page 18

9.4.3 House pressure regulator

A

Each gas appliance which is connected to the propane installation must be provided with its own house pressure regulator. The house pressure regulator is a third party delivery.

The house pressure regulator must have a minimum capacity of 10 kg/h / 37 mbar and a CE certification.

ATAG advices to install the house pressure regulator as close as possible to the boiler. When placing the regulator inside, a discharge drain of ø6mm must be installed. The discharge drain must be directed outdoor. In case of a discharge the gasses will go outside.

If fitting the regulator outside the regulator should be protected against influences of the weather. The (de-) aeration must be positioned downwards (see figure 9.5.3.a).

ATAG advices to install measure points on all gas line parts to have the possibility to check for pressure loss.

Pre-pressure must be adjusted to 37 mbar by means of the house pressure regulator. The maximum permitted closing pressure may be 5 mbar higher than the maximum pre-pressure.

A too high closing pressure in the low pressure gas line can be caused by a high resistance or jam in this gas line. When the closing pressure keeps increasing the valve in the regulator is not closing correctly. In this case the regulator should be replaced.

9.4.4 Dimensioning of the low pressure gas line

The gas line from the house pressure regulator to the boiler must have the dimensions according the table below.

Boiler type i15R i18R i24R i32R i40R
Diameter gas line m m m m m
ø15mm - - - - -
ø22mm 18 18 18 18 18
ø28mm 30 30 30 30 30

9.4.5 De-aerating the LPG tank

When placing a new or revised LPG tank the tank must always be de-aerated.

ATAG advices to inform the gas supplier that a central heating boiler is connected to the LPG tank. For the boiler it is absolutely necessary that the tank is free of air. When not the boiler will give ignition problems and will not function.

ATAG advices to measure the content of O2. This value should be lower than 1.3%. Contact the gas supplier in case of doubt.

Page 19

9.5 Condensation drain pipe

The ATAG condensing boiler has the >88% Efficient SEDBUK 2009 for high energy efficiency in heating and domestic hot water. The ATAG wall hung gas fired condensing boiler contain a siphonic condensate trap to collect and realease condensate. The amount of condensate formed is determind by the type of boiler and the water temperature produced by the boiler.

Condensate pipework.

Use plastic pipework of an internal diameter no less then 19mm ID (typically 22mm OD).

Routing of the pipework,

The condensate pipework must fall at least 45mm per metre away from the boiler, taking the shortest practicle route to the termination point.

Support the pipe at least every 50 cm for near horizontal sections and 1 metre for vertical sections. Wherever possible, the condensate pipework should be routed internally to prevent freezing. In order to minimise the risk of freezing during prolonged very cold spells, one of the following methods of terminating condensate drainage pipe should be adopted.

Internal pipework

Wherever possible, the condensate drainage pipe should be terminated at a suitable internal foul water discharge point such as (a) an internal soil and vent stack or (b) an internal kitchen or bathroom waste pipe, washing machine waste pipe etc. A suitable permanent connection to the foul waste pipe should be used. Figures 9.5.1, 9.5.2(a), 9.5.2(b) show appropriate connection methods.

The possibility of waste pipes freezing downstream of the connection point should be considered when determining a suitable connection point - e.g. a slightly longer pipe run to an internal soil stack may be preferable to a shorter run connecting into a kitchen waste pipe discharging directly through the wall to an external drain.

Where "gravity discharge" to an internal termination is not physically possible (e.g. the discharge point is above the appliance location, or access is obstructed by a doorway), or where very long internal pipe runs would be required to reach a suitable discharge point, the following measures may be adopted.

Use of a condensate pump (to an internal termination):

Condensate can be removed using a proprietary condensate pump (third party delivery), of a specification recommended by the pump manufacturer.

The pump outlet should discharge to a suitable internal foul water discharge point, such as (a) an internal soil and vent stack or (b) an internal kitchen or bathroom waste pipe, washing machine waste pipe etc. Figure 9.5.3 shows a typical connection method.

A suitable permanent connection to the foul waste pipe should be used and the manufacturer's detailed installation instructions for the pump should be followed.

External pipework

The use of an externally-run condensate drainage pipe, terminating at a suitable foul water discharge point or purpose-designed soakaway, may be also be considered; however if this termination method is chosen then the following measures should be adopted

  • The pipe should be run internally as far as possible before going externally and the pipe diameter should be increased to a minimum of 30mm ID (typically 32mm OD) before it passes through the wall.
  • The external run should be kept as short as possible, taking the most direct and "most vertical" route possible to the discharge point, with no horizontal sections in which condensate might collect. Do not exceed 3 metres outside the dwelling.
  • The external pipe should be insulated using suitable waterproof and weatherproof insulation ("Class O" pipe insulation is suitable for this purpose).
  • The use of fittings, elbows etc should be kept to a minimum and any internal "burrs" on cut pipework should be removed so that the internal pipe section is as smooth as possible.

The customer/householder should be advised that even with the above measures this type of installation could freeze, and that if this were to occur then boiler shutdown could result, requiring remedial action - possibly involving a chargeable engineer call-out.

Where there are likely to be extremes of temperature or wind-chill, the use of a proprietary trace-heating system for external condensate drainage pipework, incorporating an external frost thermostat, should therefore be considered. If such a system is used then the installation instructions of the trace heating manufacturer and any specific recommendations regarding pipe diameter, insulation, etc. should be followed. All other relevant guidance on condensate drainage pipe installation should also be followed.

Other cold weather protection methods approved or endorsed by boiler manufacturers and/or service organisations may be adopted if these are considered suitable by the parties involved.

If an external soil/vent stack is used as the external termination then the connection method shown in Figure 9.5.4 should be used, together with the measures on insulation etc. as described above and shown in the diagram.

When a rain water downpipe is used as the termination (NB only permissible if this downpipe passes to a combined foul and rainwater drainage system) an air break must be installed between the condensate drainage pipe and the downpipe to avoid reverse flow of rainwater into the boiler should the downpipe itself become flooded or frozen. Figure 9.5.5 shows a suitable connection method.

Where the condensate drainage pipe is terminated over an open foul drain or gully, the pipe should terminate below the grating level, but above water level, in order to minimise "wind chill" at the open end. Pipe drainage will be improved if the end is cut at 45° as opposed to a straight cut. The use of a drain cover (such as those used to prevent blockage by leaves) may offer further protection from wind chill. Figure 9.5.6 shows a suitable connection method.

Where the condensate drain pipe terminates in a purpose-designed soakaway (see BS 6798:2014 or boiler installation manual for soakaway design requirements) any above-ground section of condensate drainage pipe should be run and insulated as described above. Figure 9.5.7 shows a suitable connection method.

Unheated internal areas:

Internal condensate drainage pipes run in unheated areas such as lofts, basements and garages should be treated as external pipe.

Draining of the condensation water to the external rain guttering is not permitted in view of the danger of freezing.

Before putting the boiler into operation fill the siphon with 150 ml of water.

9.6 Flue gas exhaust system

The flue gas exhaust system and air supply system consists of:

  • Flue gas pipe;
  • Air supply pipe;

- Roof or wall terminal.

The flue gas exhaust system and air supply system must comply with:

The flue gas outlet and air supply installation must comply with the current regulation requirements in accordance with BS:5440 Part 1 and 2.

The ATAG iR boiler as described in this manual is NOT suitable for a combined flue system.

The appliance concentric connection diameter is 60/100 mm, to which the flue gas outlet and air supply system can be fitted, with or without elbow pieces. The maximum permissible pipe length is set out in Table 9.6.2.a.

For further information about the available components of the flue gas and air supply system we recommend you consult the Flue system literature. Combinations with other brands or systems are, without written permission from ATAG Heating, not permitted.

The ATAG flue gas system is meant, and designed, solely for the use on ATAG central heating boilers adjusted to Nat gas or LPG. For this purpose the CE Certificate has been supplemented under the Gastec nr: 0063CQ3634 The maximum flue gas temperatures are below 70°C (full load 80/60°C).

The proper operation may be adversely influenced by changes of or adjustments to the correct set up. Possible warranty claims will not be honoured if incorrect changes result in non compliance with the installation manual or local rules and regulations.

9.6.1 Flue terminal locations

The terminal should be located where dispersal of combustion products is not unimpeded and with due regard for the damage or discolouration that might occur to parts of the building in the vicinity (see fig 9.6.1.c).

In certain weather conditions condensation may also accumulate on the outside of the air inlet pipe. Such conditions must be considered and where necessary insulation of the inlet pipe may be required. In cold and/or humid weather water vapour may condense on leaving the flue terminal. The effect of such 'plumeing' must be considered.

The terminal must not be located in a place where it is likely to cause a nuisance, where the terminal is less than 2m (6.6ft) above a pavement or platform to which people have access (including) any balcony or flat roof. The terminal must be protected by a guard of durable material.

Where a terminal is fitted below a window which is hinged at the top, and where the hinge axis is horizontal, and the window opens outwards, the terminal shall be 1m below the bottom of the window opening.

The flue must be terminated in a place not likely to cause a nuisance.

For horizontal flue terminal direct to the rear or side through the wall (only 1 bend and 1 wall terminal) the terminal should be placed horizontal. The flue pipe inside the terminal is fitted in a 3 degrees angle to ensure the condensation water can run back to the boiler. See figure 9.6.1.a.

For longer horizontal sections, the outlet system should always be fitted on an incline (52 mm/m = 3°) sloping down towards the boiler so that no condensation water is able to accumulate in the outlet system. The chances of icicles forming on the outlet is minimised by causing the condensation water to run back towards the boiler. See figure 9.6.1.b.

Notes:

  • In addition, the terminal should not be nearer than 150mm to the framework of an opening into the building, i.e. a window surround or door surround. This clearance may be reduced to 25mm without effecting the performance of the boiler. However, to ensure the condensate plume does not affect adjacent
  • surfaces a clearance of 300mm is preferable.
  • These clearances may be reduced to 25mm without effecting the performance of the boiler. However, to ensure the condensate plume does not affect adjacent These dealances may be reduced to 25mm without energing the promance of the bolint. However, to ensure the condensate plane does not anect adjace surfaces the terminal can be extended beyond gutters, pipes, eaves, balconies etc. To reduce the possibility of nuisance to neighbouring buildings etc. it is recommended the terminal should not be less than 2500mm from car parking spaces,
  • building boundary walls, fences etc.
  • A terminal must not be sited under a car port roof
  • a comman must not be steed under a car port root. In certain weather conditions the terminal will emit a plume of steam. If possible avoid positioning the terminal where this may cause a nuisance, i.e. positions A, D, G, H, J, or M.
  • The flue terminal must be exposed to the external air and the position must allow the free passage of air across it at all times.
  • A terminal must not be sited below 2m where people have access to, such as public footpaths, access routes, patios etc. However, If the terminal is fitted less than 2m above a surface where there is no public access the terminal must be protected by a terminal guard
Page 26

The appliance produces a white wisp of condensate (plumeing). This wisp of condensation is harmless, but can be unattractive, particularly in the case of outlets in outside walls. For wall terminals a plume management kit is available as an option (see fig. 9.6.1.d).

Plume management kit

3 The flue cannot be lower than 1,000 mm from the top of the light well due to the build up of combustion products.
4 1,200 mm between air intake and facing terminal.
5 Internal/external corners. The air intake clearance can be reduced to 150 mm providing the flue exhaust outlet has a 300 mm clearance.
6 600 mm distance to a boundary or surface facing a boundary, unless it will cause a nuisance.
BS 5440: Part 1 recommends that care is taken when siting terminals in relation to boundaries.

  • See also Notes on previous page. Plume kits running horizontally must have a 10° fall back to the boiler for proper disposal of condensate.
  • For details on specific lengths see relevant chapter Dimensioning of the flue gas and air intake duct.

Page 27

9.6.2 Dimensioning of the flue gas and air intake duct

The total length of the run of the flue is determined by the flue diameter, including for the connection pipe, elbows fittings and terminal covers etc..

An incorrect dimensioned flue system can lead to disorders. Look at table 9.6.2.a for the choice of the boiler and the corresponding maximum equivalent flue length.

Explanation table 9.6.2.a:

Concentric flue gas system:

maximum noted length L = distance between boiler (from elbow or vertical adapter) and the end of terminal

When using bends the noted value behind every bend should be deducted from the maximum straight length.

Dimensions flue gas system and air supply system

Concentric flue system ø60/100 (Horizontal & Vertical)

Maximum equivalent length (L) m 15 ç 9
45° bend resistance length m -1.3 -1 .3
87° bend resistance length m -1.9 -1 .9

Example:

An i24R with a concentric flue gas system ø60/100mm has according to the table a maximum flue straight length of 15m In the system that is going to be put in there are 2 x 45° bends, so the maximum flue gas length is 15 – (2 x -1.3) = 12.4m.

Flue dimensions

Rear Flue L = wall thickness (B) + 150mm

Side Flue

L = wall thickness (B) + distance between boiler and wall (C) + 150mm

If the length L is more than 580mm rear flue or 585mm side flue, then a Horizontal flue fixed length 1000mm (60/100mm) with elbow (FA100205) will need to be used instead, up to 810mm.

Figure 9.6.2.b

Page 28

Fitting the flue

Note : If it is required to cut an extension, DO NOT cut the end of the inner duct that incorporates the seal joint. Ensure the inner duct end without the seal joint is cut so that it is flush with the outer duct.

Ensure that all cuts are square and free from burrs.

Once assembled with the components pushed home, the flue is fully sealed.

Making good the wall with a sealing method such as sand and cement, or an air and watertight grommet seal such as FlueSnug is acceptable and local regulations should always be adhered to. If a grommet seal is to be used, ensure that each flue joint is screwed, and the flue is screwed to the flue elbow. A flue bracket should also be used at each section in accordance with the below guidance to provide stability to the flue. A combination of a grommet seal and making good the wall is also acceptable.

  • 1. Adjust the telescopic flue and secure with sealing tape supplied or cut the fixed length terminal flue to the required length.
  • 2. Fit the flue to the extensions (if required) by locating the inner duct into the seal joint and push fully home the inner and outer duct.
  • 3. When connecting the horizontal flue terminal length ensure the terminal end outlet is at the uppermost part of the flue.
  • 4. Pass the terminal flue assembly through the wall.
  • 5. Fit the bend to the boiler turret.
  • 6. If the inside sealing collar (white) is being used, then it will need to be fitted before assembling the flue and making good the inside wall.
  • 7. Pull the flue assembly towards the bend, locating the inner duct into the seal joint on the bend and secure the flue assembly to the bend by pushing fully home (Outer flue duct must be seen through the small inspection hole to confirm fully home).
  • 8. Make good the outside wall and fit the outside sealing collar onto the location provided immediately behind the flue terminal grille.

Note: The white of the flue can be on show or extended outside the dwelling wall as it is UV protected.

When mounting the flue gas system, pay attention to the flow direction (See figure 9.6.2.b). It is not permitted to mount a system upside down and will lead to complaints. Use the special grease (supplied in the accessory bag with the boiler) to simplify the fitting.

The ATAG flue system used is a push fit flue system, which does not require screws to be fitted at each flue joint, however this should be done if using a grommet to seal the flue on both sides of the wall to ensure the flue is secured. The flue system must be adequately supported at regular intervals between brackets of no more than 1.0 metres for horizontal sections and no more than 2.0 metres for vertical sections.

97 Fitting the boiler onto the boiler frame

After the pipe work of gas, heating installation installation has been fitted to the boiler frame, the boiler can be placed on the boilerframe

Before hanging the boiler to the boiler frame remove first the cover of the boiler first. The cover is also the air cabinet and is attached to the boiler case with 2 fasteners (A and B) (see figure 8.a).

Note that there is an earth cable (when present) to disconnect when removing the cover from the boiler. Free space for removing the connector is 400mm. Remember to connect this earth cable (when present) when replacing the cover.

Always refit and turn the 2 screws tight in the fasteners A and B after replacing the cover.

Remove furthermore the 4 plastic caps from the boiler connections.

When removing the plastic sealing caps from the pipes, contaminated testing water may be released.

Lift the boiler only by the boilers case.

Lifting and carrying precautions:

  • Lift only a manageable weight or ask for help
  • When lifting the boiler, bend the knees, and keep the back straight and feet apart.
  • Do not lift and twist at the same time.
  • Lift and carry the boiler close to the body
  • Wear protective clothing and gloves to protect from any sharp edges.

10 Electrical connection

The appliance complies with the actual directives. The installation must continue to comply with:

  • A 230V -50Hz mains electrical supply is required fused externally at 3A.
  • A deviation on the grid of 230V (+10% or -15%) and 50Hz
  • the national rules for electrical installations.

The appliance must be connected to an earthed socket. This must be visible and within reach.

The following general stipulations also apply:

  • No changes may be made to the wiring of the appliance;
  • All connections should be designed in accordance with the enclosed regulations:

Page 32

10.1 External safety contact (white)

This connection comes with a loop of wire. This loop enables the boiler to work. Removing the loop will stop the boiler from firing up.

The connection can be used to connect a condensate pump safety overflow switch, where this will stop the boiler from firing if the condensate pump cannot get rid of the condensate water and the safety overflow switch is triggered

10.2 DHW sensor connection (yellow)

N/A not applicable.

10.3 OpenTherm BUS & ON / OFF connection (blue)

This PCB will detect if an OpenTherm or an On / Off device is connected to the blue plug on the terminal block.

An OpenTherm compatible device as well as a volt free on / off thermostat or programmable room thermostat can be used to switch on or off the heat demand to the boiler.

10.4 ATAG Zone connection (red)

The ATAG One zone smart room thermostat is the primary candidate for use of the ATAG zone eBus connection. The smart room thermostat can also be substituted by another ATAG zone compatible room controller, this eBus enables the boiler to modulate set point temperatures for optimal efficiency. On top of the thermostats, the connection is used for other ATAG zone compatible devices such as zone management accessories.

10.5 Solar inlet sensor connection (grey)

N/A not applicable.

10.6 ATAG Outside sensor (rose)

When a weather compensation sensor (supplied with the boiler) is used, the two wires from the outside sensor get wired into the plug supplied on the terminal block in the rose connector position.

10.09 230V Control Block (230V live output, aqua blue)

f a live, neutral or earth wire is required for an external clock/programmer these can be taken from the (L) live, (N) Neutral or (E) earth 230V live output aqua blue connections on the 230v control terminal block. If an external 230V clock/programmer is used, then a switched live is required from the control(s) to connect to the 230V control aqua blue connector in position (SwL) Switched live to fire up the boiler.

10.10 230V Control Block (SwL Switched live, aqua blue)

If a 230V room thermostat is used, then a switched live is required from the control(s) to connect to the 230V control aqua blue connector in position (SwL) Switched live to fire up the boiler. This could be in series after the clock/ programmer to the room stat, then to SwL on the 230V control aqua blue connector.

10.11 External pump (230V live output, green)

The system pump MUST be wired directly back to the boiler into the (L) live pump, (N) Neutral pump and (E) earth pump 230V live output to pump connections on the 230V control terminal block. This is so the boiler can control when the pump is operated. This will allow the boiler to run the pump for the pump overrun feature, which will last 60 seconds.

11 Filling system

The central heating installation needs to be filled with potable water according to the requirements in chapter 9.3 'Water quality'. For filling the CH installation, use the the feed and expansion header tank. Use the following procedure:

1 Ensure all system and boiler drain points are closed;
2 Open all isolation and motorised valves;
3 Turn on the water supply to the system header tank
4 Vent all radiators and pipework;
5 Check system for any visable leaks;

When powering up the boiler (described in chapter 13) an automatic air purge program will run to vent the boiler.

The boiler is equipped with self-managing control system. This control system takes over a large part of the manual settings, which simplifies the start-up of the installation considerably.

After filling the installation and switching on the electrical power supply a short start-up program is activated. This shows all digits, boiler type and software version and the automatic air purge program is activated. The automatic air purge program lasts for approx. 7 minutes and stops automatically. Then the boiler will switch on for the enabled program.

CH controls

With a demand from the heating controls, the boiler activates its 1 minute delay period. This is to prevent the heat exchanger from losing its heat too quickly in the event of a hot water demand. Then the pump starts and after 30 seconds the gradient control becomes active. The starting point of the gradient control is the currently existing flow temperature. A Delta-T control (25K) ensures a stable control according to heat request.

If the flow temperature is below the T-set value of 20°C the boiler will immediately start.

If during a demand from the heating the burner switches off, because the desired flow temperature is exceeded, there will be an anti-cycle time in operation for 5 minutes. This means that the burner switches on again after 5 minutes if there is still a demand from the heating.

The ATAG iR is equipped with boiler sensors of 10kOhm. The resistance value and corresponding temperature are shown in the accompanying table.

12.6 Pump function

By default the boiler is set in such a manner that the pump will switch on in case of a heat request for CH or DHW. Switching on and off is managed entirely by the control system.

Danger of frost

If there is danger of frost damage to the CH installation, it is advisable to let the pump run continuously, proceed as follows:

Boiler frost protection

If the (T1) flow sensor registers a temperature of 5°C or below in the boiler, the boiler will fire up. The boiler keeps on firing until the temperature reaches 10°C (measured on the flow sensor) and the boiler switches off again.

Page 44

13 Commissioning the boiler

Make sure before the boiler is put into operation that the boiler and installation have been fully vented. Vent the gas line and open the gas isolation valve to the boiler. The boiler requires no adjustment of the burner pressure and quantity, because it is self-regulatory and has been set in the factory and should not be reset.

  • 1. Turn on the boiler electrical supply;
  • 2. When the boiler starts up for the first time the following screens will be shown:
Device discovery
14.09.18
Initializing
14.09.18
Airpurge active
⊞

  • 3. After filling the 7 minute air purge cycle starts;
  • 4. Vent the entire heating installation starting at the lowest point;

The automatic air purge program will take approx. 7 minutes and will be followed by the home screen.

The iR boilers are supplied with a flow switch. If the external pump starts, the flow switch is made, the burner is set free, if the flow switch is not made the boiler will not fire.

Page 45

Work on the installation and/or boiler should only be carried out by qualified personnel with calibrated equipment.

At the time of commissioning, complete all revelant sections of the Benchmark Checklist located on At the line of commission, ..., the inside back pages of the document.

For maintenance of the boiler the cover has to be removed. Unscrew the 2 locking screws from the fasteners at the top of the boiler, unlock the fasteners and remove the cover in a forward motion. See figure 16.a

Always refit and turn the 2 screws tight in the fasteners A and B.

Changing settings, such as the burner pressure and the amount of air flow, is superfluous. Only in case of a failure or when replacing the gas block, venturi and/or fan, the CO, percentage should be checked.

Always check all gas carrying parts for leaks (with a leak detection spray) after (maintenance) work to the boiler.

Close the relevant commissioning valves during the maintenance activities. See figure 15.a.

Draining the boiler

The heating installation must be provided with a fill and drain valve. Use this feature also for draining the boiler.

Figure 15.a

13.1 Checking the CO,

The CO, check consists of 2 steps or, if necessary, 3 steps:

Step 1:Check on full loadStep 2:Check on low loadStep 3:Adjustment (if necessary).

Step 1: CO, check on full load

The CO2 setting is preset at the factory on all boilers. A calibrated Flue Gas Analyser must be carried out during commissioning.

- Ensure that the boiler is in operation and that the heat, which it produces, can be discharged.

Set the full load

You can set the full load of the boiler as follows:

Measuring point CO, Figure 15.1.a

  • Press the chimney sweep button for 5 seconds:
  • Turn the selector wheel until you reach 100%;
  • Press OK;

The boiler will switch to maximum power output of the boiler: the screen shows 100% (heating capacity)

  • Calibrate the Flue Gas Analyser, and then insert the flue gas probe of the Flue Gas Analyser into the measuring point of the flue gas pipe "a" (see illustration).
  • Wait for one minute and then carry out a combustion analysis.
  • Check whether the CO2 values that are listed below correspond to the measured value.

After this check has been done at full load, the CO2 value at low load need to be tested (see Step 2 on page 47). If there are any deviations in the result, then these must be corrected (see Step 3 on page 48).

CO 2 check on full load (Step 1)
Full load Natural gas (G20) Propane (G31)*
00 Nominal 9.0% Nominal 10.3%
CO 2 Nominal 9.0% Minimum 8.6%, maximum 9.6% Minimum 9.9%, maximum 11.0%

Values are valid with closed cover/air box.

* Only possible if LPG conversion kit is installed!

Page 47

Step 2: CO, check on low load

Set the low load

The low load of the boiler can be set by you as follows:

Measuring point CO2 Figure 15.1.a

  • Turn the selector wheel until you reach 0%;
  • Press OK;

The boiler will switch to minimum power output (low load) of the boiler;

the screen shows 0% (heating capacity).

The CO2 value at low load must be lower than the CO2 value at full load. The measuring procedure must be carried out, until a constant value is achieved. Please contact ATAG, if the values should lie outside of the applicable tolerances.

End of measuring:

- Press the back button for 5 seconds to exit chimney sweep mode.

This completes the procedure.

The maximum duration of the commissioning function, without interruption, is 20 minutes.

CO 2 check on low load (Step 2)
Low load Natural gas (G20) Propan e (G31)*

8.8% 8.5% - 7.5% 10.2% 10.1% - 8.9%
8.7% 8.4% - 7.5% 10.1% 10.0% - 8.9%
8.6% 8.3% - 7.5% 10.0% 9.9% - 8.9%
9.9% 9.8% - 8.9%

Values are valid with closed cover/air box

* Only possible if LPG conversion kit is installed!

Page 48

Step 3: Adjustment on the gas valve

Adjust the gas value only in case the measured values lies out of range of the values mentioned in the table on previous page.

  • Open the boiler as described on page 55;
  • Set the boiler on full load (see Step 1)
  • The CO2 values are set by using an Allen key (2 mm), or a large flat head screwdriver, on the screw "b".

Please observe the following rotating direction:

  • Clockwise means less CO
  • Counterclockwise means more CO

After this setting has been made, once more test the CO2 value at full load and low load. See Step 1 and 2.

Leaend

  • a Measuring point for the flue gas
    • Set screw for CO2
Adjustment of the gas valve in case the measured values lies out of range of the values on full load (Step 3)

13.2 CO and combustion checks

IMPORTANT PRELIMINARY INFORMATION ON CHECKS

NOTE: The air gas ratio valve is factory set and must not be adjusted during commissioning unless this action is recommended following contact with the manufacturer.

If any such adjustment is recommended and further checking of the boiler is required the installer/service engineer must be competent to carry out this work and to use the flue gas analyser accordingly.

If the boiler requires conversion to operate with a different gas family (e.g. conversion from natural gas to LPG) separate guidance will be provided by the boiler manufacturer

PRIOR TO CO LEVEL AND COMBUSTION RATIO CHECK

The boiler manufacturer's installation instructions should have been followed, gas type verified and gas supply pressure/rate checked as required prior to commissioning.

As part of the installation process, especially where a flue has been fitted by persons other than the boiler installer , visually check the integrity of the whole flue system to confirm that all components are correctly assembled, fixed and supported. Check that manufacturer's max. flue lengths have not been exceeded and all guidance has been followed (e.g. Gas Safe Technical Bulletin TB008 where chimney/flues are in voids).

The Flue Gas Analyser should be of the correct type, as specified by BS 7967

Prior to its use, the flue gas analyser should have been maintained and calibrated as specified by the manufacturer. The installer must have the relevant competence for use of the analyser.

Check and zero the analyser IN FRESH AIR as per analyser manufacturer's instructions. Key:

CO = carbon monoxide CO 2 = carbon dioxide O 2 = oxygen ppm = parts per million Combustion ratio = The CO reading measured in ppm divided by the CO2 reading first converted to ppm GU(I&U)R = Gas safety (Installation & use) Regulation.

15 Routine servicing

ATAG Heating Technology advises on an interim service inspection with a flue gas analyser. A full strip down service is recommended at regular intervals or where analyser readings are not within correct safety standards.

Required tools:

  • Cross head screwdriver;
  • T-handle key set with 3 bits (hex key 4mm, hex key 5mm and cross head PZ2);
  • Open end wrench 8mm.

15.1 Interim Service

For reasons of safety and economy, it is recommended that the boiler is serviced annually. Servicing must be performed by a competent person in accordance with BS 7967.

After servicing, complete the relevant Service Interval Record section of the Benchmark Checklist located on the inside back page of this document.

Figure 16.a

In order to perform maintenance, the following actions have to be taken;

  • Switch off the electrical power to the boiler;
  • Remove the screws from the 2 fasteners A and B (see fig. 16.a);
  • Unlock the fasteners A and B and remove the cover in a forward motion.

Always refit and turn the 2 screws tight in the fasteners A and B.

Air box/cover

The cover also doubles as air box:

- Clean the air box/cover with a cloth and a non-abrasive cleaner;

Siphon (see fig. 16.b)

The degree of pollution resedue in the siphon is an important indication for the need of maintenance

  • Turn the control unit towards by moving the handle (C) slightly to the left (see figure 16.a);
  • Turn/pull the sealing ring (1) downwards;
  • Turn the siphon securing clip (2) anti-clockwise;
  • Pull the siphon cup (3) and siphon pipe (4) out of the heat exchanger;
  • Take the siphon cup and pipe out of the boiler by moving it downwards or turn it in forward motion upwards along the heat exchanger;
  • Clean the parts by rinsing them with water;
  • Check the O-ring of the siphon cup and replace it if necessary;
  • Grease the O-ring again with acid-free O-ring grease to simplify the reassembly.

Reassembly takes place in reverse order.

  • fill the siphon with 150 ml of water.
  • If a leakage has occurred to the siphon, replace the entire siphon.

Page 58

If the interior of the boiler looks heavily polluted with dust / dirt, then a full service should be performed even with acceptable combustion readings (CO/CO2 ratio).

Put the boiler back into operation and carry out a flue gas analysis (see page 46).

Always put back the cover after (maintenance) work and secure it with screws A and B. Always refit and turn the 2 screws tight in the fasteners A and B.

Note: During routine servicing, and after any maintenance or change of part of the combustion circuit, the following must be checked:

Checking the CO,

- Check the CO2 readings at full load and low load as described in section 13.1

Checking CO readings and Combustion Performance (CO/CO, ratio)

- Check CO readings and Combustion Performance as described in Section 13.2

The combustion reading (CO/CO2 ratio) must be less than 0.004. If the combustion reading (CO/CO2 ratio) is greater than this, and the integrity of the complete flue system and combustion circuit seals has been verified, and the inlet gas pressure and gas rate are satisfactory either:

  • Perform the 'Full Service'.
  • Perform 'Setting the Gas Valve'.

15.2 Full Service

For reasons of safety and economy, it is recommended that the boiler is serviced annually. Servicing must be performed by a competent person in accordance with BS 7967-4.

After servicing, complete the relevant Service Interval Record section of the Benchmark Checklist located on the inside back page of this document.

Where a full service is required the following steps must be followed:

- Carry out the actions as described in section 15.1 Interim Service.

Page 59

Fan unit and burner cassette (see fig. 13.2.b-f)

  • Remove the velcro from the silencer and remove the silencer (1);
  • Unscrew the coupling (2) of the gas block and the coupling on the venturi (3) and remove the gasline (4):
  • Replace the gaskets of the gasline (O-ring) with new ones;

Disconnect the electrical connections from the fan (5):

  • Turn the left (6) and right (7) clamp bars a guarter turn with the hex key and pull these out in a forward motion. Mind the direction of rotation (red control cams);
  • Now lift the complete fan unit (5) with the upper tray of the heat exchanger and remove it in a forward motion:
  • Turn the unit up side down and remove the burner cassette (8) from the ventilator unit;
  • Check the burner cassette for wear and tear, pollution and any breakages. Clean the burner cassette with a soft brush and vacuum cleaner. In the case of breakages, always replace the complete burner cassette (8);
Page 60

The following operations must be performed carefully in relation to the vulnerability of the non return valve.

- After removing the burner cassette (8) the non return valve (12) becomes visible. Check that the non return valve entire circumference closes / seals completely. The valve should be able to move freely from fully open to fully closed (see fig. 16.e). Replace the non return valve if the valve does not seal properly. Follow the instructions supplied with the new part.

  • Replace the gasket (9) between the burner (8) and upper casing (10);
  • Replace the gasket (11) between the upper casing (10) and exchanger (Note the position in figure 16.f): Check the venturi (13) for pollution and clean them with a soft brush in combination with a vacuum cleaner, if necessary.

If the inside of the boiler casing is heavily polluted with dust, it is likely that the fan impeller is also polluted. To clean the fan, it has to be removed from the upper tray and the venturi. Clean the impeller with a soft brush and a vacuum cleaner. Replace the gasket and take care that the new gasket is installed properly when reassembling the fan parts.

Figure 16.h

Reassembly takes place in reverse order.

Heat exchanger

Check the heat exchanger for pollution. Clean it, if necessary, with a soft brush and a vacuum cleaner. Avoid any pollution falling down.

Benchmark Commissioning & Warranty Validation Service Record

It is a requirement that the boiler is installed and commissioned to the manufacturers' instructions and the data fields on the commissioning checklist completed in full.

To instigate the boiler warranty the boiler needs to be registered with the manufacturer within one month of the installation. The warranty rests with the end-user (consumer), and they should be made aware it is ultimately their responsibility to register with the manufacturer, within the allotted time period.

It is essential that the boiler is serviced in line with the manufacturers' recommendations, at least annually. This must be carried out by a competent Gas Safe registered engineer. The service details should be recorded on the Benchmark Service and Interim Boiler Work Record and left with the householder. Failure to comply with the manufacturers' servicing instructions and requirements will invalidate the warranty.

www.hhic.co.uk

ommissioning Checklist is to be completed in full by the competent person who commissioned the boiler as a means of demonstrating iance with the appropriate Building Regulations and then handed to the customer to keep for future reference.

to install and commission according to the manufacturers' instructions and complete this Benchmark Commissioning Checklist will invalidate the ty. This does not affect the customer's statutory rights.

tions in England and Wales must be notified to Local Authority Building Control (LABC) either directly or through a Persons Scheme. A Building Regulations Compliance Certificate will then be issued to the customer.
