Condensate discharge
Where possible the condensate should discharge into an internal soil pipe or waste system. The
minimum pipe diameter required is 22 mm, a trap has already been fitted to the appliance with a flexible
tail to facilitate the connection to the condensate discharge pipe.
The pipe should be a solvent weld plastic, not copper, as the condensate has a ph value of
4 (slightly acidic).
Where it is not possible to terminate internally, the condensate discharge pipe may be run
outside (see below drawing).
Any external run is subjet to freezing, in severe weather conditions. To avoid this the pipework
should be installed to dispose of the condensate quickly, with as much as possible run internally,
before passing through the wall.
Pipework external to the building should be increased in diameter to 32 or 40 mm solvent weld. It should
be run to a external drain or soakaway, with a maximum lenth of 3 metres.
If a soakaway (condensate absorption point) is used, it should be constructs as shown below.
