Assembly Practice - Keston 30C Installation And Servicing Instructions

16 ASSEMBLY PRACTICE

Remove all plastic debris and burrs when installing air intake
piping. Plastic fillings caused by cutting muPVC 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.
INSTALLING FLUE AND AIR PIPES ONTO
THE TWIN FLUE BOX
Important - When installing the boiler on an existing system a
new flue and air intake system MUST also be installed. You
MUST NOT re-use existing flue or air pipework components.
•
Remove the twin flue box from Pack 2b supplied with
the boiler.
•
Remove boiler front panel - Frame 45
•
Position flue box on top of the boiler (see diagram)
•
Clamp onto boiler using horseshoe clamp provided in
boiler packaging box.
•
Fix box to the boiler top panel using 6 x M5 screws
provided.
•
Measure, cut and check the air and flue pipes to pass to
the exit from the wall(s) or ceiling.
•
Always thoroughly deburr all pipes and most
important, remove shavings from within the pipe.
•
Assemble, using solvent weld cement, the pipework
from the boiler connections to the exit from the first wall/
ceiling, (remount the boiler if removed). When pushing
pipe through walls, ensure grit and dust is not allowed
to enter the pipe.
Ensure pipes are fully engaged into sockets and
solvent welded with no leaks.

INSTALLATION
•
Using the same methods drill any further holes (always
covering existing pipework), cut and assemble the
pipework.
•
From outside, complete the two terminations - See
Frame 9 Flue System and make good all holes. (Wall
sealing collars are available to make good hole areas
on the wall face (part number C.08.0.00.07.0).
•
Support any pipes whose route could be displaced
either of its own accord or by accident. Any horizontal
run over 1m or vertical runs of any length must always
be supported. Brackets should be placed at intervals
of approximately 1m. Brackets should be loose
enough on the pipe to allow thermal expansion and
contraction movement.
•
Flue pipework through walls MUST be sleeved to allow
thermal expansion and contraction movement.
•
Check all connections for security and re-seal any joints
using solvent cement where soundness may be in
doubt.
Note. It is equally important to seal the air inlet with solvent
cement as the flue outlet pipe joints.
