Flueing guidelines
Every gas fireplace 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 that the
appliance is provided with an
effective flue. Some guidelines
to assist with flue design are
listed below. These must be
read and modified as necessary
with reference to the particular
installation.
The Rinnai Arriva must be
installed with an approved
Rinnai flue system. Approved
flue components for this
appliance are detailed in this
guide.
Clearance to combustibles
• Flue transition (p. 12) - 5 mm
• Elbow component of
adaption flue kit (ASPKIT03)
- 25 mm
All other Arriva flue
components have zero
clearance.
Flashings
Flashings to top of chimney
structure do not form part
of the flue kit and must be
specified.
Flue support
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.
Vertical terminations: 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 which should be clear of
the ridge line. Lesser clearances
may provide perfectly adequate
flue systems depending on
the installation. Minimum
clearances are shown in
AS/NZS 5601.1.
Minimum clearance
500 mm to nearest
part of roof
Shared flues
Gas appliances must not be
connected to a chimney or flue
serving a separate fuel burning
appliance.
