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 coaxial vertical flue kit.
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.
Flue cowl clearance
To ensure products of combustion are cleared, adequate clearance
from 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 where the
flue cowl should be 500 mm clear of the ridge line.
An adequate flow of fresh air must exist around the flue cowl
following installation.
Minimum clearances are shown in AS/NS 5601.1
Shared flues
Gas appliances must not be connected to a chimney or flue serving a separate flue burning
appliance.
