g) The last pipe section may be cut to fit the distance required to reach the water heater
flue connections. If a flue condense tap is specified then install the supplied trap with
crimped end into the gasketed end of the elbow (horizontal flue installations) and clamp
the condensate tee and elbow together. Then 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. Then 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 condense
trap connector and install 40mm OD waste pipe to suitable drain, (see fig.8).
Note: On all flue installations, for distances over 1.5 metres, we recommend that a
condensate trap is fitted.
