10.0Installation

10.1Unpacking & Initial Preparation

The gas supply, gas type and pressure must be checked for suitability before connection (see Section 7.4).

NOTE: A small amount of water may drain from the boiler in the upright position.

1.Remove staples, open flaps and remove the cardboard sheet. Remove the polystyrene side pieces and literature. Two people can then lift out the boiler (Figs. 39 & 40).

2.After considering the site requirements

(see Section 7.0) position the fixing template on the wall ensuring it is level both horizontally and vertically.

3.Mark the position of the two most suitable fixing slots for the wall plate and boiler lower fixing holes. It is preferable to use the vertical fixing slots.

4.Mark the position of the centre of the flue hole (rear exit). For side flue exit, mark as shown (Fig. 41).

5.If required, mark the position of the gas and water pipes. Remove the template.

6.Cut the hole for the flue (minimum diameter 116mm).

7.Drill the wall as previously marked to accept the wall plugs supplied. Secure the wall plate using the fixing screws.

8.Using a spirit level ensure that the plate is level before finally tightening the screws.

9.Connect the gas and water pipes to the valves on the wall plate using the copper tails supplied. Ensure that the sealing washers are fitted between the connections.

IMPORTANT: ONLY on 40 models the Cold Water Inlet tap is fitted with a flow regulator. The copper tail is factory fitted on this model, but must be loosened and turned through 180° to point downwards. Ensure the joint is fully tight (Fig. 42a).

10.Fit the filling loop as described in the instructions supplied with it.

10.2Flushing

1.Connect a tube to the central heating flow or return pipe (Fig. 42).

2.Flush thoroughly (see System Details, Section 6.2).
