INDOOR FLUE INSTALLATION
For indoor installations a purpose built indoor model must be used or the outdoor unit converted by an authorised
person. The appliance will be labelled as an indoor model and a 125 mm flue adaptor will be fitted to the
appliance. Flue for indoor units must be purchased through AstralPool and can be run up to 8m in length.
Heater must be installed to AS5601. Access and suitable working areas must be available to the heater.
Flue pipe is supplied with a galvanised sleeved end for the external application and an unsleeved aluminium end
for fitment to appliance. The flue pipe can be cut shorter with a knife / saw.
1/ Pre bend the flue where required.
Bends are made by curving the flue pipe around a gentle radius such as a pipe or knee. Do not over bend and
kink flue pipe. Keep bends to a minimum and use as large as radius as possible. Minimum internal radius is
250mm.
Bends can be restraightened if required.
2/ Fit flue pipe to appliance (unsleeved end of flue). Insert flue connection fully into flue pipe.
Fit hose clamp to connection and tighten.
3/ Form extra bends where required. Care should be taken when forming bends to not create a low point where
condensation may collect. Condensation should be able to drain to the heater or out the flue outlet.
The flue should be bracketed at intervals of 1 M using standard 125 mm standoff brackets available at most
plumbing suppliers.
