CONDENSATE PIPEWORK:
• The condensate pipe must be a minimum of
21.5mm Ø plastic pipe.
• The condensate pipe work must fall at least
52mm per metre towards the outlet and
should take the shortest practicable route.
• Ensure there are no blockages in the pipe
run.
CONDENSATE PIPEWORK RUN
EXTERNALLY:
• Pipe work length should be kept to a
minimum and the route as vertical as possible.
• Weather proof insulation must be used.
• Care should be taken when siting a
soakaway to avoid obstructing existing
services.
• The condensate pipe work must fall at least
52mm per metre towards the outlet and
should take the shortest practicable route.
• Ensure there are no blockages in the pipe
run.
4 The external run be kept as short as possible
and not exceed three metres.
4 The pipe diameter should be increased to
32mm.
4 The pipe should be insulated using suitable
waterproof and weather resistant insulation.
4 The external pipe should take the shortest
and least exposed route to the discharge
point, and should "fall" as steeply as
possible away from the boiler, with no
horizontal runs in which condensate might
stand.
4 The use of fittings, elbows etc. should be
kept to a minimum and any internal "burrs"
on cut pipe work should be removed so that
the internal pipe section is as smooth as
possible.
