27 CONDENSATE DRAIN

Refer also to the British Gas document: 'Guidance
Notes for the Installation of Domestic Gas
Condensing Boilers' (1989).
The boiler comes with an integral 100mm
condensate trap. The boiler condensate drain
must be connected to a drainage point, preferably
within the building. This condensate drainage
should be run in standard 21.5mm overflow pipe.
Before fitting drain pipe remove plastic plug from
connection. Connection to the boiler is by push fit
into the rubber collar protruding from the boiler.
Ensure that the condensate trap is full of water
before commissioning the boiler . Refer to Frame
30.
The routing of the drain must be made to allow a
minimum fall of 1 in 20 away from the boiler,
throughout its length.
The drainage pipework must be arranged so that
obstruction (e.g. through freezing) of external
drainage pipe does not give rise to spillage within
the dwelling.
IMPORTANT.
If excessive external pipework cannot be avoided
an additional siphon kit or a condensate removal
pump (both available as an option) and insulation
are recommended to prevent possible freezing.
All pipework and fittings in the condensate drain
system must be made of plastic. No other
materials may be used.
The drain outlet on the boiler is standard 21.5mm
overflow pipe. This size must not be reduced in
any part of its length.
