Assembly Practice - Keston HEAT 2 45 Installation & Servicing

2.10 ASSEMBLY PRACTICE

Remove all plastic debris and burrs when installing air intake
piping. Plastic filings 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 a replacement boiler, a new flue
system is recommended.
However re-using the existing boiler flue installation is acceptable
if the installer adheres to Section 2.7 Flue System - Important,
and also checks and confirms the following:
•
Remove the flue adaptor and air spigot from the flue pack
supplied with the boiler.
•
Remove boiler front panel - Refer to 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 6 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). Care must be taken when
applying solvent weld to ensure it does not come into contact
with the sample plug. 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.

Flue Sampling Point
•
Using the same methods drill any further holes (always
covering existing pipework), cut and assemble the pipework.
•
From outside, complete the two terminations - Se
Section 2.7 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.
•
Check Sample plug for free movement and seating.
Note. It is equally important to seal the air inlet with solvent
cement as the flue outlet pipe joints.
