b) Connection into the domestic waste water drain
pipe (e.g. a sink or washing machine) with an exter-
nal termination.
The condensate drain pipe should have a minimum
diameter of 22 mm, without length restriction, and
also be fitted with a siphon (3) having a connection
head of 75 mm (fitted within the boiler already).
The connection should be made after the drain
siphon if possible. If the installation is only possible
in front of the siphon, there must be a ventilation
valve between the two siphons. This is normally
provided in a drain.
c) Draining into a gully (5) under the grid (6) and
above the water level. The external piping should
be kept as short as possible to minimise the frost
risk, and should be no longer than 3 m.
d) To the condensate absorption point (drainage
ditch) (7). The external pipe should have a maxi-
mum length of 3 m.
Further information can be obtained from "BS 6798
Specification for installation of gas–fired boilers of rated
input not exceeding 70 kW net". The condense trap (1)
must be filled with water as described in the relevant
chapter before the boiler is commissioned.
