Installation Of The Boiler - Keston C90 Installation And Servicing Instrucnion

WD352/0/2003
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 brackets, plug the hole and
fix in position.
c. Using a spirit level make sure
the brackets are completely
level individually and relative to
each
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
suffice).
3.2 MOUNTING THE BOILER - CAUTION MULTI-PERSON LIFT
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 (Part No C.34.0.06.00.0)
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
When installing a replacement boiler, a new flue system must be fitted. DO NOT
RE-USE THE ORIGINAL FLUE SYSTEM.
Remember the flue pipe must slope downwards back towards the boiler and this is best
achieved using 92.5
a. From the two connections on the boiler, mark the positions of the two holes for
the flue and air pipes on the wall(s) or ceiling. To allow access to drill the holes it
may be necessary to temporarily remove the boiler. If the boiler stays put then it is
imperative that the front doors are closed and the two plastic pipes capped off
