10.4 Fitting The Boiler
1. Lift the boiler using the Lifting Points as shown by the
shaded areas (Fig. 43). The boiler should be lifted by TWO
PEOPLE. Engage the slots at the top rear of the boiler on the
wall plate(see Safe Manual Handling page 5).
2. Pull the lower polystyrene cap off the boiler (where used).
Ease the boiler forwards and remove the sealing caps from the
boiler connections.
NOTE: A small amount of water may drain from the boiler
once the caps are removed.
3. Insert the sealing washers between the valves and pipes on
the wall plate and the boiler connections.
4. Tighten all the connections.
10.5 Fitting the Pressure Relief Discharge Pipe
(Fig. 44)
1. Remove the discharge pipe from the kit.
2. Determine the routing of the discharge pipe in the vicinity of
the boiler. Make up as much of the pipework as is practical,
including the discharge pipe supplied.
3. The pipework must be at least 15mm diameter and run
continuously downwards to a discharge point outside the
building. See section 6.7 for further details.
4. Utilising one of the sealing washers, connect the discharge
pipe to the adaptor and tighten the nut.
5. Complete the discharge pipework and route it to the
outside discharge point.
IMPORTANT: Make all soldered joints before connecting
to the pressure relief valve.
10.6 Condensate Drain (see section 7.7)
1. Connect the condensate drain to the trap outlet pipe.
Ensure the discharge of condensate complies with any
national or local regulations in force (see British Gas
“Guidance Notes for the Installation of Domestic Gas
Condensing Boilers”.
2. The connection will accept 21.5mm (
3
/
4
in) plastic overflow
pipe which should generally discharge internally into the
household drainage system. If this is not possible, discharge into
an outside drain is acceptable.
