Before mounting the boiler on the wall, the condensate
drain (provided in the h/ware pack) must be connected
from the boiler 'S' trap to a drainage point, preferably
within the building.
Ensure that the condensate trap is full of water before
commissioning the boiler. Refer to Frame 25.
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 and insulation are recommended,
in order 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 21.5 mm
overflow pipe. This size must not be reduced in any part
of its length.
If external condensate pipe run is greater than 3m then
pipe must be 32mm nominal diameter. Consideration
must be given to insulating external condensate pipe
runs.
