Check Site Requirements (section 7.0) before
commencing.
8.1 Initial Preparation
The gas supply, gas type and pressure must be checked
for suitability before connection (see Section 7.6).
NOTE: If the boiler is to be pre-plumbed, follow both
these instructions and those on the boiler pack.
1. Remove the fixing template (Fig. 20) from the fixing
carton.
2. After considering the site requirements (see Section 7.0)
position the template on the wall ensuring it is level both
horizontally and vertically.
3. Mark the position of the top centre hole for the wallplate.
4. Mark the condensate discharge pipe area.
5. Mark the centre of the flue hole (rear exit). For side exit,
mark as shown. If required, mark the position of the gas and
water pipes. Remove the template.
6. Cut the hole for the flue (minimum diameter 125mm) (see
table opposite for wall thickness flue diameter's).
7. Drill and plug the wall as previously marked. Secure the
wallplate to the wall by the top centre hole.
8. Ensuring the wallplate is level both horizontally and
vertically, drill and plug the remaining 4 securing positions at
the top and bottom through the wallplate. Utilising the slots
available ensure the wallplate is square and secure to the
wall.
9. Connect the gas, water and the pressure relief discharge
pipes to the valves on the support bracket using the copper
tails supplied. Ensure the sealing washers are fitted correctly
to the water connections.
10. Loosely route the condensate discharge pipe to the area
previously marked.
8.2 Flushing
1. Insert a tube into the valve outlet furthest from the filling
loop (Fig. 21).
2. Flush thoroughly (see System Details, Section 6.0).
