Page 12: Connecting The Boiler
Connecting the boiler The boiler has the following connection pipes, which can be connected left or right to the boiler by means of turning the knee fitting (all connections are positioned to the left from factory); The central heating pipes (See figure 7). These can be connected to the installation by means of the supplied compression fittings(1xT-piece) 28 mm x1"... - Page 13 Cold and hot water pipes (See figure 10). These consist of 22mm copper pipes and can be connected to the installation by means of compression fittings. See further chapter 6.5. Flow to absorber Return from absorber Cold water pipe Hot water pipe Thermomanometer Secondary circulation pipe (only 380 litre)

Page 14: Central Heating System
6.1 Central Heating system Connect the central heating system according to local 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). Install the drain valve with the T-piece in the CH return pipe within reach. It is not necessary to install a heat trap in the central heating pipes. -
Page 15: Expansion Vessel
5 All Q-Solar boilers are provided with an expansion vessel connection. This pipe is connected between the three way valve and boiler pump. This prevents the expansion water produced during heating or hot water operation from being closed off from the expansion vessel, when the thermostatic radiator valves are fully closed. -
Page 16: Underfloor Heating System (Plastic Pipes)
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. -
Page 17: Hot Water Supply
6.5 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 must be provided with the supplied DHW safety group (see figure 13) consisting of (counted in the water flow direction): - Pressure reducing valve with integral strainer - Check valve... -
Page 18: Secondary Dhw Circulation
6.5.1 Secondary DHW Circulation. In case of long DHW pipe runs one can connect a secondary circulation pipe to the Q-Solar. This improves the comfort because the waiting times can be reduced to a few seconds The return of this pipe is connected to position Z on the Q-Solar. -
Page 19: Condensation Drain Pipe
The condensate pipe must be run using suitable corrosion resistant materials (eg. plastic). 6.6.1 Condensate discharge ATAG Condensing boilers have the top SEDBUK 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. - Page 20 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. 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.

Page 21: Flue Gas Exhaust System And Air Supply System
6.7 Flue gas exhaust system and air supply 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: United Kingdom: The flue gas outlet and air supply installation must comply with the current regulation requirements. - Page 22 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 maximum permissible pipe length is set out in Table 8. Boiler conversion from concentric to parallel It is also possible to use a parallel pipe connection of 2x 80mm.
- Page 23 Monopass Flue system literature. The ATAG flue gas system is ment, 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)
- Page 24 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.

Filling and venting the installation Fill the following parts of the installation: cylinder (secondary DHW circuit) solar circuit (see page 21) central heating system (primary circuit) 10.1 Filling the cylinder (secondary DHW circuit) Do not manually open the temperature and pressure relief valve or expansion relief valve for venting purposes (any foreign matter in the pipework may cause damage to the valve seats). -
Page 36: Central Heating System (Primary Circuit)
10.2 Central heating system (primary circuit) Do not use boiler pressure relief valve for venting purposes. The complete primary heating system must be flushed out with cold and hot water. Fill and vent the central heating system as detailed in the boiler installation instructions. -
Page 37: Commissioning The Boiler
Commissioning the boiler Before the boiler is fired, ensure that the boiler and the system are well vented and free of air. Purge the gas line between the gas meter and the boiler and carry out a gas soundness test as specified in the current Gas Safety Installation & Use Regulations. The boiler does not require adjustment of the burner pressure and air quantity because it is self adjusting and is factory set at the correct value. -
Page 38: Adjustments
In certain cases adjustment have to be altered in case of : Lower flow temperature Read through the Parameter chapter to adjust the boiler to its installation. Contact ATAG Heating in case of doubt.

Page 41: Isolating The Boiler
Isolating the boiler In some situations it may be that the entire boiler must be switched off. By switching off the three keys with the lamps for central heating, hot water and pump programme ), the boiler is switched off. Leave the plug in the wall socket, which means the circulation pump and the three-way valve are activated once every 24 hours in order to prevent jamming. -
Page 42: Checking For Contamination
13.1 Checking for contamination In order to be able to check the boiler for contamination in the following years it is advisable to measure the maximum air displacement in the boiler when putting the boiler into operation. This value can be different with each type of boiler. In order to be able to measure this value follow the next procedure: Press the MODE-key for 5 seconds. -
Page 43: Checking The Co2/O2
13.2 Checking the CO The CO percentage is factory-set. This has to be checked at commissioning, maintance and faults. This can be checked by means of the following procedure: Remove the black cover of the gas valve by unscrewing the sealed screw. Put the boiler into operation and take care that it can deliver its heat;... -
