Flue terminal locations
Flue terminals must be compliant with the flue
terminal locations shown in AS/NZS 5601.1.
The flue cannot terminate under a floor or in a
roof space.
Self-supporting flue
The weight of the flue system should not be
supported by the appliance—it should be self-
supporting.
Supporting the flue is usually completed
during the framing stage with flue supports
or straps within the cavity. Wall straps have
been included in the Rinnai vertical flue kits.
Elbow straps are also available as a separate
component to prevent excess weight on the
flue elbow.
Horizontal runs of flue pipe
Horizontal runs of flue pipe must be supported
to prevent any downward sags. Horizontal pipe
sections should be supported every 1.2 m. Wall
straps can be used for this purpose.
The horizontal run of flue pipe must
have a 20 mm rise for every 1 m of run
towards the flue termination, NEVER
WARNING
allow the flue pipe to run downwards
towards the horizontal flue terminal.
A downward slope can trap heat and
become a fire hazard.
Shared flues
Gas appliances must not be connected to a
chimney or flue serving a separate fuel burning
appliance.
Flashings
Flashings are not included with the Ember
flue kits, these must be specified. The only
exception is the flashing kit provided in the
horizontal flue kit.
