8.0 Installation

8.4 Fitting The Boiler

1. Lift the boiler using the lower edges. Engage

the slots at the top rear of the boiler on the wall

plate hooks (Fig. 23).

2. Ensure that the boiler is level and sits against

the wall.

3. Take the two steel washers and remaining

screws. Using the previously drilled and plugged

holes, secure the bottom of the boiler to the wall

(Fig. 24).

4. Remove the elbows, valves and sealing

washers from the packaging. The

/4 in valve with

internal filter must be fitted to the central heating

return. The filter is visible through the branch

connection of the valve.

5. Using the sealing washers provided connect

the valves to the heating flow and return, and the

cold water inlet.

6. Connect the elbows to the gas service cock

and hot water outlet pipe, and then connect the

elbows to the boiler. Connect the elbows with

flared ends to the valves.

7. Ensure that the sealing washers are used on

all connections. The rubber washers must be

used on the gas connections.

8. The gas and water supplies, central heating

flow and return and domestic hot water flow can

now be connected.

8.5 Fitting the Pressure Relief

Discharge Pipe (Fig. 25)

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 (Fig. 26). 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.
