CONDENSATE DRAINAGE

Connect the condensate drainage system to the boiler. It is advisable to use a detachable
fitting at connection to the boiler to enable easy removal for servicing.
Fill the condensate trap by pouring water into the boiler flue spigot until water is seen to
flow freely from the condensate drainage system. Make the final connection of flue pipe to
the boiler using the push on coupling supplied.

Installation & Servicing Instructions
Measure, cut and check the air and flue pipes to pass to the exit from the
wall(s) or ceiling.
Assemble, using adhesive, 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.
Connect the condensate drainage system and fill the condensate trap by
pouring water down the boiler flue spigot ( See Section 3.5 Condensate
Drainage).
Make the final connection of flue and
air pipe to the boiler using push on, or
plastic compression couplings. Ensure
that the connectors are set vertically
otherwise leakage of condensate may
occur which will corrode the casing. Do
not use adhesive on the 'push on' end
of the connecting couplings.
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 2.8 Flue
System and make good all holes.
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.
Check all connections for security and re-seal any joints using sovent
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.
