3. INSTALLATION OF THE BOILER
Read Chapter 2 - 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.
3.1
WALL MOUNTING BRACKET
a
Place the bracket on the wall
horizontally with the pre-drilled
holes at the bottom.
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).
3.2
MOUNTING THE BOILER
a
Using the detachable side lift
handles supplied or via winch, lift and locate the upper rear lip on the boiler to the
boiler wall bracket.
b
Move the boiler sideways to centralise the boiler on the bracket.
3.3
FLOOR STANDING FRAME - OPTIONAL
If the optional floor standing frame is selected the frame should first be assemble and
secured firmly to the plant room floor. Suitable assembly instructions are included with the
floor standing frame pack.
Lift the boiler and lower into position onto the frame.
3.4
ASSEMBLY PRACTICE
Remove all plastic debris and burrs when installing air intake piping. Plastic filings caused
by cutting Keston Composite plastic pipe must not be allowed to be drawn into the
combustion air blower. Prevent dust entering the air intake when cutting on building sites.
Blower failure which is determined to be caused by plastic filings or other debris will not be
covered by guarantee.
3.5
INSTALLING FLUE AND AIR PIPES
Remember the flue pipe must slope downwards back towards the boiler and this is best
achieved using 92.5
