f) 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,
Straight end
install the crimped end of the condensate trap directly onto
(ungasketed)
the water heater flue connection.
g) Carefully measure the length of straight flue pipe needed,
allowing for about 50mm (2in) insertion into the elbow. Mark
the un-gasketed 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.
h) Use the clamp supplied in the flue kit with the stepped
gasket to seal the elbow or condensate trap to the concentric
flue connector.
i) 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.15)..
Note
On all flue installations, for distances over 1.5 metres, we
recommend that a condensate trap is fitted.
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.
