4. INSTALLATION OF THE BOILER
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.
4.1
WALL MOUNTING BRACKET
a
Place the bracket on the wall
horizontally
with
the
pre-drilled
holes
at
the
bottom
and
position
as
dictated by the template
supplied within the boiler
packaging.
b
Drill through the centre hole
of the bracket, plug the hole
and fix in position.
c
Using a spirit level make
sure
the
bracket
is
completely level and mark
the position of the other
screw holes.
d
Remove the bracket and drill
the holes in the positions
marked. Plug these holes.
e
Screw the bracket to the wall
using
screws
of
an
appropriate size for the wall
type (No. 12 x 2 inch wood
screws normally suffice).
f
Fix the cross spacer to the
wall bracket locating pegs
and
mark
the
resulting
location for the pre-installation jig dictated by the lower ends of the cross spacer.
g
Drill and plug the holes for the pre-installation jig.
h
Screw the pre-installation jig to the wall using screws of an appropriate size for the wall
type.
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.
