Publication No. 5111811
8.1 Initial Preparation
The gas supply, gas type and pressure must be
checked for suitability before connection (see
Section 7.4).
1. After considering the site requirements
(see Section 7.0) position the fixing template on the
wall ensuring it is level both horizontally and
vertically.
2. 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 horizontal fixing slots. For
side flue exit, mark as shown (Fig. 18).
3. Mark the position of the centre of the flue hole
(rear exit). For side flue exit, mark as shown.
4. If required, mark the position of the gas and water
pipes. Remove the template.
5. Cut the hole for the flue (minimum diameter
116mm).
6. Drill the wall as previously marked to accept the
wall plugs supplied. Secure the wall plate using two
of the fixing screws.
7. Using a spirit level ensure that the plate is level
before finally tightening the screws.
8.2 Flushing
1. Connect a tube to the central heating flow or
return pipe (Fig. 19).
2. Flush thoroughly (see System Details, Section
6.2).
8.3 Preparing The Boiler
1. Remove all packaging.
2. Stand the boiler on its base by using the rear
lower edge as a pivot.
NOTE: A small amount of water may drain from
the boiler in the upright position.
