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
Flueing for the Novo, depending on the
installation:
•
Mock chimney coaxial flueing
•
Masonry colinear flueing
Flexible aluminium flues that come straight
off the fire.
Self-supporting flue - mock chimney
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.
Elbow straps are also available as a separate
component to prevent excess weight on the
flue elbow (if used).
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.

Coaxial flue
25 mm from the outer flue to a
combustible surface to allow
for expansion and contraction
of the outer flue components.
Ember adaptor (transition)
25 mm clearance to a
combustible surface―the
underside of the adaptor has
zero clearance and can be
installed straight into wooden
support joists.
Ø 100 mm exhaust flexi flue
Requires a 50 mm clearance to
