Unpacking & Initial Preparation
The gas supply, gas type and pressure must be checked for
suitability before connection (see Section 7.4).
1. Remove staples, open flaps and remove cardboard sheet.
Remove the polystyrene side pieces and literature. Two
people can then lift out the boiler (Fig. 39).
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. 40).
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.
