7.6 Condensate pipe work
INFORMATION
The condensate discharge system MUST be made of plastic, no other materials may
be used. The discharge duct MUST have a minimum gradient of 5~20 mm/m.
Condensate discharge via the gutter is NOT allowed due to risk of frost and the
possible damage to the materials.
7.6.1 Internal connections
If possible, the condensate drain pipe should be routed and terminated so that the
condensate drains away from the boiler under gravity to a suitable internal foul
water discharge point such as an internal soil and vent stack. A suitable permanent
connection to the foul waste pipe should be used.

If the first option is NOT possible, an internal kitchen or bathroom waste pipe,
washing machine pipe can be used. Make sure that the condensate drain pipe is
connected downstream of the waste trap.

Condensate pump
Where gravity discharge to an internal termination is NOT physically possible or
where very long internal runs of drainage pipe would be required to reach a
suitable discharge point, condensate should be removed by using a proprietary
condensate pump (field supply).
