21 CONDENSATE DRAIN
Refer also to the British Gas document: 'Guidance Notes
for the Installation of Domestic Gas Condensing Boilers'
(1989).
Ensure that the siphon is full of water before
commissioning the boiler . Refer to Frame 24.
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.
All pipework and fittings in the condensate drain system
must be made of plastic. No other materials may be
used. The maximum length of external plastic pipework
is 3m and must be insulated.
The drain outlet on the boiler is standard 21.5mm
overflow pipe and is suitable for either push fit or solvent
weld applications. This size must not be reduced in any
part of its length.
The boiler includes as standard, a 75mm condensate
trap. The condensate trap also includes a siphon to
reduce the possibility of freezing in the drain outlet.
