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
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.

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
