If an external pipe run is unavoidable then the run should
be insulated with water proof insulation limited to 3 m in
length. Should this be exceeded then the pipework
diameter should be increased to 32mm and the
pipework insulated using weather proof materials.
It should be noted that the connection of a condensate
pipe to a drain may be subject to local building controls.
Material for condensate
The condensate drainage pipe should be run in a
standard drain pipe material, e.g. PVC (polyvinyl
chloride), PVC-U (unplasticized polyvinyl chloride),
BS (acrylonitrile-butadienestyrene), PP (polypropylene
polyprolene) or PVC-C (cross-linked polyvinyl chloride).
The condensate drain can be attached to the syphon
(fig. 5).
Any internal pipework should be of a diameter to match
the requirements of the condensate exit pipe on the
appliance.
Internal termination to internal stack
The condensate drainage pipe should have a minimum
outside diameter of 1" with no length restriction. It should
incorporate a trap with a 75 mm condensate seal and be
connected to the stack at a point at least 450 mm above
the invert of the stack.
The trap built into the boiler will
provide this 75 mm (fig. 6)
condensate seal
.
WARNING!
WARNING!
Any external run must be insulated with
water proof insulation.
