Flueing guidelines
Inner flue: Clearance to combustibles
Clearance from the inner flue to a combustible material must be greater than 25 mm.
Flue cowl clearance
To ensure products of combustion are cleared, adequate clearance for the building is required.
The flue cowl should have a 500 mm clearance from any part of the building. This also applies to
steeped and pitched roofs which should be clear of the ridge line as shown. Lesser clearances
may provide perfectly adequate flue systems depending on the installation. Minimum
clearances are shown in AS/NZS 5601.1.
Flue terminal locations
Must be compliant with ‘Clearances Required for Flue Terminals’ from AS/NZS 5601.1. The flue is
not to terminate under floors 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.
Shared flues
Gas appliances must not be connected to a chimney or flue serving a separate fuel burning
appliance.
Flashings to to the top of the chimney structure do not form part of the flue kit and
must be specified.
