Connect the flexible tube (where applicable with the overflow
pipe from the pressure relief valve) to the drain via an open
connection.
WARNING
▪ ALWAYS fill the condensate trap with water and place
it on the boiler before powering up the boiler. See
illustration below.
▪ NOT placing or filling up the condensate trap may
cause flue gases to come into the installation room and
can lead to dangerous situations!
▪ In order to place the condensate trap, the front cover
MUST be pulled forward or removed entirely.
NOTICE
It is recommended that any external condensate pipe is
insulated and increased to Ø32 mm in order to prevent the
condensate from freezing.
7.3 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.
7.3.1 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

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).
The pump outlet pipe should discharge to a suitable internal foul
water discharge point such as an internal soil and vent stack,
internal kitchen, bathroom waste pipe, or washing machine waste
pipe. A suitable permanent connection to the foul waste pipe should
be used.
