Ensure the discharge of condensate complies with any
national or local regulations (BS 6798).
Condensate discharge pipe must be PVC, PVC-U, PVC-
C or PP. Metal pipe work is not suitable.

external termination with sink, to drain or gully
A boiler discharge pump must be used
if there is no drain or sink nearby that
the condensate can be discharged into.
Condensate discharge pump is not
standard part of the boiler. Further
information must be followed supplied
with the pump.
Condensate discharge must be installed
correctly, otherwise operation of the
boiler will
be affected negatively.
It is recommended to make condensate
discharge internally into the household
drainage
system. If it is not possible,
needed precaution must be taken to
prevent freezing.

Boiler
CAUTION:
Disconnect power supply to
prevent electrical shock before
connecting the electrical supply.
CAUTION:
If the supply cord is
damaged, it must be replaced by the gas
safe engineer in order to avoid a hazard.
CAUTION:
The
≤ 3 A
bipolar fuse (BS
1362) with a minimum contact opening of
3 mm must be used in the electrical
connection of the boiler.
CAUTION:
The
cable
diameter
(including insulation) of the electrical
installation to be installed must be at
least 14 mm and the pipe diameter
used must be at least 16 mm.
