Chapter 4 : Installation
Read Chapter 3 - Boiler Location and decide upon the position of the boiler.
Installation of the boiler is straightforward but consideration must be given to access to allow flue
and air pipes to be pushed through walls and ceilings. The order in which the components are
installed will depend upon particular site conditions, but in general it will be easiest and most
accurate to install the boiler and then build up the flue outlet and air inlet pipes to the terminal - this
is the sequence described.

If you have purchase the optional pre-installation jig you are now able to connect system
pipework to the pre-installation jig, isolate using the valves supplied as part of the jig and
pressure test the system pipework prior to mounting of the boiler. System flushing and
cleaning should also be carried out at this stage prior to boiler mounting.
4.2
MOUNTING THE BOILER (after system cleaning and testing)
a
Lift and locate the boiler onto the stud and the two locating pegs protruding from
the wall bracket. (lift the boiler via the back frame only)
b
Lower the boiler for hanging on the two pegs.
c
Fix the boiler on the bracket stud using the nut and the washers supplied.
d
Make the gas, DHW, CWS, flow and return connections to the system or, if a
pre-installation jig is being used, the pre-installation jig valves using the swivel nut
connections supplied. Ensure the compound gasket inserts are in place inside the
swivel nut face before tightening. Check all joints for soundness.
