Novo flueing
Every gas fire requires a flue system that will draw effectively and clear
flue products safely under all potential wind and climatic conditions. It is
the responsibility of the installer to ensure the appliance is provided with
an effective flue.
Some guidelines to assist with flue design are detailed in this guide.
These must be read and modified as necessary depending on the
installation. The Novo must be installed with an approved flue system,
approved components are shown in this guide.
General flueing guidelines
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.
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.
Shared flues
Gas appliances must not be connected to a chimney or flue serving a separate flue burning
appliance.
Flashings
Flashings are not included in the flue kits. Flashings
must comply with E2, this is the responsibility of the
installer.
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
