10.0 Installation

10.1 Unpacking & Initial Preparation
The gas supply, gas type and pressure must be checked for
suitability before connection (see Section 7.4).
1. If pre-plumbing is required turn the unopened carton
over and remove the staples. Open the flaps and remove
the cardboard sheet, template and wall plate.
2. The wall plate can then be used to pre-plumb the system,
and the carton turned back over.
3. Alternatively, remove the staples from the top of the
carton, open the flaps and remove the cardboard sheet.
Remove the polystyrene side pieces. Two people can then
lift out the boiler.
Note: A small amount of water may drain from the boiler
in the upright position.
4. After considering the site requirements
(see Section 7.0) position the fixing template on the wall
ensuring it is level both horizontally and vertically.
5. 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.
6. Mark the position of the centre of the flue hole (rear
exit). For side flue exit, mark as shown (Fig. 34).
7. If required, mark the position of the gas and water pipes.
Remove the template.
8. Cut the hole for the flue (minimum diameter 116mm).
9. Drill the wall as previously marked to accept the wall
plugs supplied. Secure the wall plate using the fixing screws.
10. Using a spirit level ensure that the plate is level before
finally tightening the screws.
11. 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.
10.2 Flushing
1. Connect a tube to the central heating flow or return pipe
(Fig. 35).
2. Flush thoroughly (see System Details, Section 6.1).
