9.0 Installation

9.1 Unpacking & Initial Preparation
IMPORTANT
RISK ASSESSMENT - Before commencing the installation
it is recommended that the 'Five Steps to Risk
Assessment' document published by the HSE is
consulted, and an assessment performed as described.
GAS SUPPLY - 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. If pre-plumbing it will be necessary
to turn the carton over to access the wall plate first.
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 (Fig. 17). Disengage the wall
plate from the boiler.
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.
4. Mark the position of the centre of the flue hole (rear exit).
For side flue exit, mark as shown (Fig. 18).
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.
NOTE: 40kW models ONLY - ensure the flow restrictor is
inserted in cold water inlet connection (Fig. 19). On other
models the restrictor is factory fitted internally.
10. Fit the filling loop as described in the instructions supplied
with it.
9.2 Flushing
1. Connect a tube to the heating flow or return pipe (Fig. 20).
2. Flush thoroughly (see System Details, Section 6.2).
