Description of the boiler

Operating Instructions ATAG QR-Series

Room sealed boiler The boiler retreives its combustion air from outside then discharges the flue gasses to the outside.
Condensing Retrieves heat from the flue gasses. Water condensates on the heat exchanger.
Modulating Higher or lower burning according to the heat demand.
Stainless steel Super solid kind of steel which keeps its quality for life. It will not rust or erode in contrast to composition materials, like aluminium.

The ATAG QR boiler is a room sealed, condensing and modulating central heating boiler, with or without an integrated hot water facility. This boiler is also approved for use as an open flued boiler according to flue category B23 and B33.
The boiler is provided with a compact stainless steel heat exchanger with smooth tubes. A well thought out principal using durable materials. The boiler burns gas for supplying warmth. The heat is transferred in the heat exchanger to the water in the central heating system. By cooling down the flue gasses condensate is formed. This results in high efficiency. The condensate, which has no effect on the heat exchanger and the function of the boiler, is drained through an internal siphon.
The boiler is provided with an intelligent control system (CMS Control Management System). The boiler anticipates the heat demand of the central heating system or the hot water facility.
When an outside sensor is connected to the boiler, the boiler works weather dependantly. This means that the boiler control measures the outside temperature and flow temperature. With this data the boiler calculates the optimal flow temperature for the installation.

Operating Instructions ATAG QR-Series

Filling and de-aeration of the ATAG QR and the heating installation The heating installation is filled according to the standard method. The installation must have been deaerated, both on the heating and the warm water side. The water pressure can be read off in bar, either on the analog pressure indicator or via the Info button. As soon as the heating installation has been filled and de-aerated, the boiler will be ready for operation.
During the initial commissioning or after a power failure, the control system starts the automatic de-aeration program. This function runs for approximately 16 minutes and stops automatically.

5 Replenishing the central heating system

3 sec.

The central heating installation needs to be filled with potable (drinking) water. For topping up the installation you use the filling loop according to the following procedure: (If in any doubt please contact your dealer)
1 Connect the filling loop to the cold water tap; 2 Slowly open the filling loop; 3 Open the cold water tap; 4 Fill up slowly to 1.5 to 1.7 bar:
Press I key and turn the knob to “water pressure”. Value on the display increases; 5 Close cold water tap; 6 Check whether the automatic de-aeration program has been running. If not yet de-aerated: Hold down the E button for more than 3 seconds. This function runs for approximately 16 minutes; 7 De- aerate the complete installation, start at the lowest point; 8 Check the waterpressure and if necessary top it up to 1,5 to 1,7 bar; 0 Close the filling loop.

After completion of the de-aeration program, the boiler will operate again.
Check the water pressure regularly and top up the installation when necessary. The working pressure of the installation should be between 1.5 and 1.7 bar when the installation is cold. (Note: Before topping up the pressure, first fill the hose with water, which prevents the entry of air into the heating system).
It can take a while before all air has dis-appeared from a filled installation. Especially in the first week noises can be heard which indicate the presence of air. The de-aeration of the boiler will make this air disappear, which means the water pressure will reduce during this period and therefore topping up with water will be necessary to adjust the flow water temperature.

DHW (Hot water) Switch off DHW program: Press the DHW function button (M) until the lowest value is reached. The beam (bar) under the tap disappears. Switching on works in reverse order.
Heating (Only works in combination with QAA55, NOT with OT/On-Off) Switch off the heating program: Press the heating mode key (I) until the bar is at the far right of the display = frost protection Switching on works in reverse order.
In case of work on the central heating system: Make sure there is no heat demand: no open hot water tap and room thermostat low. Set the main switch to 0 and pull the plug out of the wall socket. When the boiler is being drained one should take into account that a part of the heating water will remain in the boiler. When risk of frost arises one should take care that the remaining central heating water in the boiler does not freeze.

Description of the boiler

Room sealed boiler The boiler retreives its combustion air to outside then discharges the flue gasses to the outside.
Condensing Retrieves heat from the flue gasses. Water condensates on the heat exchanger.
Modulating Higher or lower burning according to the heat demand.
Stainless Super solid kind of steel which keeps its quality for life. It will not rust or erode in contrast to composition materials, like aluminium.

The ATAG QR boiler is a room sealed, condensing and modulating central heating boiler, with or without an integrated hot water facility.
The boiler is provided with a compact stainless steel heat exchanger with smooth tubes. A well thought out principal using durable materials. The boiler burns gas for supplying warmth. The heat is transferred in the heat exchanger to the water in the central heating system. By cooling down the flue gasses condensate is formed. This results in high efficiency. The condensate, which has no effect on the heat exchanger and the function of the boiler, is drained through an internal siphon.
The boiler is provided with an intelligent control system (CMS Control Management System). The boiler anticipates the heat demand of the central heating system or the hot water facility.
When an outside sensor is connected to the boiler works weather dependantly. This means that the boiler control measures the outside temperature and flow temperature. With this data the boiler calculates the optimal flow temperature for the installation.

Explanation of the type indication: Q = Type 51 = Nominal load in kW C = Combi (S = Solo)
R = Refresh

5 Mounting the boiler
Install the boiler in a well-ventilated boiler room in accordance to the actual local regulations BS5440-2:2000. The room where the boiler will be placed must always be frost free. 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 BS 6798, Clause 12, and BS5440:2 may be disregarded. The boiler can be mounted practically to any wall with the suspension bracket 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 250 mm working space in order to be able to fit a coaxial flue system or a twin supply. On the left side of the boiler at least 50 mm and on the right side 10 mm must be reserved to allow fitting or removing of casing. The location of the boiler can be determined by using the template located inside the boiler packaging. Lift the boiler only by the boilers rear wall plate.
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.

Connecting the boiler

The boiler has the following connection pipes; – The central heating pipes.
These can be connected to the installation by means of compression fittings; – The gas pipe.
It is provided with a female thread into which the tail piece of the supplied gas isolation valve can be screwed; – The condensation drain pipe. It consists of an oval 24 mm plastic pipe. The drain pipe can be connected to this by means of an open connection. If the open connection is fitted in a different location, then the pipe can be lengthened by means of a 32 mm PVC sleeve; – The flue gas exhaust system and air supply system. It consists of a concentric connection 80/125 mm. The Q51SR and Q60SR are supplied with this feature for converting from the standard 2x 80 mm to concentric 80/125 mm. – Cold and hot water pipes. Only Combi boilers: These consist of 15 mm copper pipe and can be connected to the installation by means of compression fittings.
It is recommended that isolation valves are fitted to all heating and hot water connections to facilitate ease of future maintenance.
It is advisable to spray-clean all of the unit’s connecting pipes and/or to sprayclean/blow-clean the installation before connecting it to the unit.

6.1 Central heating system

Connect the central heating system according to the actual regulations.

The boiler pipes can be connected to the installation by means of compression fittings. Reducers should be used for connecting to thick-walled pipe (welded or threaded).

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

The boiler has a self-adjusting and self-protecting control system for the load and the pump capacity. This means the temperature difference between the flow and return water is checked. Table 6.1.a shows the water displacement which supplies the circulation pump at certain installation resistance.

Installation & Servicing Instructions ATAG QR-Series

A low velocity header must be connected to the Q51CR, Q51SR and Q60SR to prevent flow problems over the boiler.
ATAG can supply the AA1OV09U Low velocity header for 1 boiler. This can be connected directly under the boiler on the flow and return pipe.

22

external installation pump with low velocity header
figure 6.1.a

If the installation resistance is higher than the stated value the pump will rotate at maximum pump capacity and the load will be adjusted until an acceptable temperature difference between flow and return water has been obtained. If, after this, the temperature difference remains to much then the boiler will switch itself off and wait until an acceptable temperature has arisen (T 20°C). If an unacceptable temperature is detected, then the control will repeatedly try to achieve water flow, and if this does not work then the boiler will switch off. If the capacity of the boiler pump is insufficient, an extra external pump can be installed in combination with a low velocity header in series with the boiler. The electrical side of this external circulation pump can be connected in the Control Panel, which means this pump switches at the same times as the boiler pump. The maximum absorbed current consumption of the external circulation pump may be 230 W (1 Amp). The extra external pump must be selected according the installation resistance and required flow.
As standard the boiler is provided with a water filter in the return pipe of the boiler. With this, possible contamination of the central heating water is prevented from ending up in the boiler. The boiler is also provided with an internal safety valve set at 3 bar. This is connected to the waste discharge together with the condensation discharge.
If all, or a substantial part of the radiators have thermostatic radiator valves or if 2-port zone valve are installed, an automatic by-pass valve must be used to prevent flow rate problems. The automatic by-pass valve used should have the same diameter as the connecting diameter of the supply and return pipe of the boiler. A decrease of pipe diameter between boiler and by-pass is not allowed. See also Annex C.
The boiler is designed to be used on sealed system only.
Additives in the installation water are only permitted in consultation with the country distributor. See chapter 6.4.
When using more than one boiler in an installation please refer to the cascade installation instructions.

6.2 Expansion vessel

The central heating system must be provided with an expansion vessel. The expansion vessel which is used should be geared to the water content of the installation. The precharge pressure depends on the installation height above the mounted expansion vessel. See table 6.2.a.

table 6.2.a

The Q51CR Combi boiler is provided with an expansion vessel connection. This pipe is connected between the three way valve and boiler pump. This prevents the expanding water, during hot water production, from being closed off from the expansion vessel, when the thermostatic radiator valves are fully closed. A second expansion vessel in the installation is not a problem. The Solo boilers Q25SR and Q38SR are provided with an expansion vessel connection. When this boiler is combined with a cylinder, the expansion vessel connection is included in the internal piping of the cylinder circuit, to which the expansion vessel can be connected.
In connection with correct functioning of the boiler it is necessary for the expansion vessel to be connected to the expansion vessel pipe of the boiler.
The Solo boilers Q51SR and Q60SR are not provided with an expansion vessel connection. When one of these Solo boilers is combined with a cylinder then one has to take into account that the expansion vessel should be connected between the three-way valve and the boiler circulation pump.

Installation & Servicing Instructions ATAG QR-Series

6.3 Underfloor heating system (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 is BS7291-1: 1990 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.
6.4 Water quality
Fill the installation with drinking 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 6.4.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 has not been flushed and/or the quality of the filling water does not meet the specifications recommended by ATAG Commercial UK Always contact ATAG Commercial UK 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 drinking water quality meets the specifications mentioned in table 6.5.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 Commercial UK 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 Frost Protection 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 afterATAG Commercial UK 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 Commercial UK expires, if the water quality does not meet ATAG Heating’s specifications or the chemical additives have not been approved by ATAG Commercial UK. – On installation and during additions or changes at a later stage, ATAG Commercial UK 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 (see Annex B – System water addetives on page 78.

6.5 Gas connection
The appliance pipe is fitted with an internal thread, into which the tail piece of the gas isolation valve can be screwed. United Kingdom: The gas supply must comply to the current Gas Safety Regulations. The connection to the appliance must include a suitable method of disconnection and a gas control cock must be installed adjacent to the appliance for isolation purposes. The nominal inlet working gas pressure measured at the appliance should be 20 mbar for Nat gas (G20). Make sure that the gas pipe work does not contain dirt, particularly with new pipes. When the boiler has to be converted from natural gas to LPG, ATAG provides special kits for this purpose. Special instructions are supplied with the kit. Always check the installation of all of the parts through which gas flows using leak detection fluid (LDF).
6.6 Hot water supply
Connection of the drinking water installation should be done according to the national water laws. The sanitary water pipes can be connected to the installation by means of compression fittings. The cold water inlet on the Combi boilers must be provided with the following (counted in the water flow direction): Flow restrictor (supplied), Safety group, Expansion vessel 6bar (potable water, blue). A flow restrictor must be fitted in the cold water pipe. The flow restrictor ensures that a quantity of water is supplied which has a guaranteed outlet temperature of 60°C (assuming a cold water temperature of 10°C). The quantity of water is virtually unaffected by the water pressure. With a water pressure lower than 1.5 bar it is advisable to remove the inside mechanism of the flow restrictor.

6.7 Condensation drain pipe
ATAG Condensing boilers have the top ErP & Energy Labelling EU 813/2013 & EU 1369/2017 band A Classification for high energy efficiency in heating and domestic hot water.
All ATAG wall hung gas fired condensing boilers contain a syphonic condensate trap to collect and realease condensate.
The amount of condensate formed is determind by the type of boilers and the water temperature produced by the boiler.
Condensate pipework.
Use plastic pipework of a diameter no less than 25mm.
Routing of the pipework,
Wherever possible, the condensate pipework should be routed internally to prevent freezing. The condensate pipework must fall at least 50mm per metre towards the outlet and take the shortest possible route Support the pipe at least every 50 cm for near horizontal sections and 1 metre for vertical sections
External pipework
The pipework should be kept to a minimum and the route as vertical as possible. Do not exceed 3 metres outside the dwelling.
The condensate pipe must be run using suitable corrosion resistant materials (eg. plastic).
Terminate as close to the ground or drain as possible (below the grating and above the water level) while still allowing for safe dispersal of the condensate. Connection of a condensate drainage pipe to a drain may be subject to local building controls.
Pipework subjected to extreme cold or wind chill conditions should be in a 40mm diameter pipe.
Protect all external pipework with weather resistant insulation and, if necessary, box in, to reduce the risk of freezing.
Making it safe.
Condensate pipework must not leak, freeze or block up. Condensate traps must be filled before firing the boiler to prevent the possibility of potential harmfull flue products evacuating via the condensate route. Do not dispose condensate into a water recovery system where it is recaimed for reuse.
Condensate can be discharged into a rainwater hopper which is part of a sewer carrying both rain water and foul water.
28

Installation & Servicing Instructions ATAG QR-Series

Final discharge options.

The appliance connection diameter is 80/125 mm, to which the flue gas outlet and air supply system can be fitted, with or without elbow pieces. The next page descibes the conversion from concentric to parallal. The Q51SR and Q60SR boiler has a connection of 2x 80mm from factory. The boiler is supplied with a flue adapter 80/125 mm to convert the boiler from parallel to a concentric connection.
The maximum permissible pipe length is set out in Table 6.8.1.a. (see page 35)
Boiler conversion from concentric to parallel It is also possible to use a parallel pipe connection of 2x 80mm. In this case a conversion kit ‘concentric to parallel’ should be ordered. Art.nr. S4440520.

All flue gas parts, which are outside the fire resistant cover, need to be in stainless steel.

We suggest you design a simple flue gas system and air supply system using table 6.8.a For further information about the available components of the flue gas and air supply system we recommend you consult the Duopass Flue system literature.
The ATAG flue gas system is meant, and designed, solely for the use on ATAG central heating boilers adjusted to Nat gas or LPG. 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.
The flue gas systems described in this document are solely suited for ATAG central heating boilers of the ATAG boiler range. For this purpose the CE Certificate has been supplemented under the Gastec nr: 0063BR3405, 0063BQ3021, 0063AS3538 and 0063AU3110. 0063BQ3021, 0063BT3195 en 0063CM3648 The flue gas system should be built up using only ATAG program products. Combinations with other brands or systems, without written permission from ATAG Commercial UK, are not permitted.
Horizontal flue system should always be installed with a 3 degree drop sloping towards the boiler, in order to avoid condensate lying in the flue system. The minimum gradient is 50mm/Mtr. With the condensate running back to the boiler the risk of ice forming at the terminal is reduced.
The terminal should be located where dispersal of combustion products is not impeded and with due regard for the damage or discolouration that might occur to building products in the vicinity (see fig 6.8.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. For protection of combustibles, refer to IS 813 section 9.10.1. 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. A suitable guard is available from the country distributor.

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.

If the boiler is to be located under stairs, a smoke alarm meeting the requirements of I.S. 409 or equivalent must be fitted.

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

For horizontal sections, the outlet system should always be fitted on an incline (50 mm/m) sloping down towards the appliance so that no condensation water is able to accumulate in the outlet system. The chances of icicles forming on the roof outlet is minimised by causing the condensation water to run back towards the appliance. In the case of horizontal outlets the inlet system should be fitted on an incline sloping down towards the outside to prevent rainwater from coming in.

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.

Installation height

Cutting the pipe goes as follows: Figure 6.8.d – Cut just as much from the air intake part as from the flue gas part using a hand saw;
– Take off the burrs from the cutting edge to prevent cutting the seals;

When mounting the flue gas system, pay attention to the flow direction (See figue 6.8.e). It is not permitted to mount a system upside down and will lead to complaints.

Use a soap solvent or special grease to simplify the fitting.

6.8.1

Dimensioning of the flue gas and air intake duct

Example: A 25kW with a concentric flue gas system ø80/125mm has according to the table a maximum flue straight length of 31m In the system that is going to be put in there are 2 x 45° bends, so the maximum flue gas length is 31 ­ ( 2 x 1.9 ) = 27.2 meters.

The flue diameter is determined by the total length of the run, including for the connection pipe, elbows fittings and terminal covers etc and the type and number of boilers installed into the system.
An undersized flue pipe can lead to disorders. Look at table 6.8.1.a for the choice of the system and the correct diameter. The table below shows the maximum flue lengths with the different boiler outputs. A longer flue gas length can be achieved by increasing the diameter to ø 100mm.
Explanation table 6.8.1.a: Two pipe flue gas system: maximum noted length = distance between boiler and roof terminal A Concentric flue gas system: maximum noted length = distance between boiler and roof terminal B
When using bends the noted value behind every bend should be deducted from the maximum straight length.

3 sec.

After switching on and with sufficient heating pressure (> 1.0 bar), the automatic heating-side de-aeration program is executed, e.g. after filling the installation for the first time. The system is then switched to safe mode (circle symbol with dash). The display shows “De-aeration program on”. The pump (s) are switched off / on a number of times. The 3-way valve, if present, is switched to the hot water position and the pump (s) are switched off / on again a number of times. At the end of the de-aeration program, which lasts approx. 16 minutes, the boiler switches back to normal operation
The venting program can also be started manually by pressing button E for more than 3 seconds. This function runs for approximately 16 minutes.
On a call for Central Heating (DHW program is switched OFF as factory setting), a water temperature will be calculated. This calculated water temperature is called the T-set value and with this the boiler output will be controlled. On a call for central heating the boiler ignites first at low input. The input is then changed slowly to match the load required. The boiler operates in this way to avoid excessive water noises and temperature overshoot.
On a call for hot water supply the T-set value of central heating return water temperature is monitored. Depending on the amount of sanitary water which is withdrawn from the DHW cylinder, the central heating return water temperature, from which the input is adjusted, will vary.
