SECTION 2 - INSTALLATION
2.10 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
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 flue adaptor and air spigot from the flue pack
supplied with the boiler.
•
Remove boiler front panel - Section 3.2.
•
Remove air intake blanking plate by unscrewing 4 x M5
screws and put to one side, leaving sponge gasket in place.
•
Fix air spigot to boiler using the 4 M5 screws, see diag.
below. Ensure sponge gasket is in place and not damaged.
•
Insert the flue adaptor into the flue manifold on the top
of the boiler and secure using the clamp provided in
the packaging box, see diagram below. Ensure the
condensate trap/siphon is filled with water.
•
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.
•
Using the same methods drill any further holes (always
covering existing pipework), cut and assemble the
pipework.
•
From outside, complete the two terminations - See
Section 2.1 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.
