10.0Installation

10.4Fitting 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.

10.5Fitting 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.

10.6Condensate 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 (3/4in) 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.
