g) The last pipe section may be cut to fit the distance
required to reach the water heater flue connections.
If a flue condensate trap is specified, install the
supplied tap with crimped end into the gasketed end
of the elbow (horizontal flue installations) and clamp
the condensate tee and elbow together. Install the
crimped end of the elbow into the flue connection of
the water heater. On vertical installations, install the
crimped end of the condensate trap directly onto the
water heater flue connection.
IMPORTANT! In order for the condensate trap to
collect and dispose of the condensate from the flue
pipe, the flue system must have a downward slope
of 21mm per metre (0.25in/ft) towards the
condensate trap. The condensate trap must be
installed as close as possible to the flue adaptor to
prevent condensate from accumulating and
draining back into the base of the water heater.

h) Carefully measure the length of straight flue pipe
needed, allowing for about 50mm (2in) insertion into
the elbow. Mark the ungasketed end of the pipe to be
cut and carefully make a straight cut on the outside
pipe to the desired length. Make sure the inside tube is
not cut. Cut the inside flue pipe about 50mm (2in)
more than the outside pipe so that the flue pipe
protrudes slightly beyond the outside pipe. Connect
the flue pipe and clamp at each end.
i) Use the clamp supplied in the flue kit with the stepped
gasket to seal the elbow or condensate trap to the
concentric flue connector.
j) Condensate disposal: Connect syphon (part no. E211)
to the 32mm slip joint condensate trap connector and
install 40mm OD waste pipe suitable drain, (see fig.8).
Note: On all flue installations, for distances over
1.5 metres, we recommend that a condensate trap
is fitted.
