Alpha InTec 40GS2 - Installation
5.4 FIT THE BOILER - Refer to Fig. 5.2
Lift the boiler and locate it on the mounting bracket - the boiler should be lifted by
two
persons.
Note:
When handling or lifting always use safe techniques - keep your back straight, bend your knees,
don't twist - move your feet, avoid bending forwards and sideways and keep the load as close to your
body as possible.
Where possible transport the boiler using a sack truck or other suitable trolley.
Always grip the boiler firmly, and before lifting feel where the weight is concentrated to establish the centre
of gravity, repositioning yourself as necessary.
5.5 CONNECT THE PIPEWORK - Fig. 5.3
There is sufficient space between the boiler chassis and the wall to run
pipework vertically behind the boiler if required.
1. Thoroughly flush out all the water pipework. Refer to Section 4.9.
2. The valves/fittings have been factory fitted, however, check that all the connections underneath the boiler have been
tightened, especially the union bends.
The heating union bends supplied have been designed to enable the heating pipes to be routed from above and/or
below using the same fitting.
Note:
When soldering to the boiler union bends, ensure the bends are not connected to the valves, otherwise the
internal seals may be damaged.
3. Connect the system pipework to the boiler. One metre of copper pipe must be fitted to the boiler before connecting to
any plastic pipework.
Note:
Do not forget that the pressure relief valve discharge pipe must be routed clear of the boiler to a drain in such a
manner that it may be seen, but cannot cause injury to persons or property.
4. Connect the 22 mm condensate trap drain pipe to the condensate discharge pipe using the clip supplied.
Ensure that the condensate discharge pipe is as required in Section 4.10.

5. The flue gas heat recovery unit relies on a store of water/condensate
to deliver maximum benefit, and must be primed prior to first use.
When the installation of the pipework is completed, fill the unit by
carefully pouring 6 litres of clean, cold water into the top central flue
spigot as shown in Fig. 5.4. Care should be taken to ensure that no
water is allowed to spill or enter the outer air duct.
Note:
It is normal for some water to run into the boiler heat
exchanger and out the condensate drain whilst filling.
6. Ensure that all the valves are closed (spindle flats at right angles to
valve) and do not turn on the water or gas supplies at this stage.
