FLUE INSTALLATION
FLUE INSTALLATION OPTIONS
These instructions ONLY apply to the Rinnai 650FS gas fire coaxial flueing system. This flue
system utilises pipe components with an aluminium inner pipe, a white plastic outer pipe and
powder coated dress pipe.
WARNING
Before commencing installation, please read the Installation Instructions located with the engine.
All Rinnai products must only be installed with Rinnai flueing as referred to in their instructions.
Rinnai appliance warranty conditions may be voided if non Rinnai Flue Components are fitted.
A Rinnai 650FS gas fire is room sealed as defined in AS/NZS 5601.
The outer plastic section of the coaxial flue complies with temperature hazard requirements and
can be installed with zero clearance to combustible material.
CUTTING THE FLUE COMPONENTS
Using the dimensions shown on page 8, calculate
the required number and type of flue components that
are needed to reach from the heater to the flue terminal.
When cutting components the outer flue pipe should be
cut to the required length plus 37mm and the inner flue
pipe should be cut to the required length plus 47mm,
this will ensure that the correct penetration is provided
for joining of components.
When inner and outer pipes are re-assembled after
cutting the inner pipe should extend 10mm beyond the
end of the outer pipe. See Fig. 1.
Cutting flue components can create sharp edges, care must be taken to avoid injury, use a file to
remove debris, burrs and sharp edges from cut ends.
IMPORTANT
Ends that are left unfinished can damage the flue seals and result in the flue components no
longer being air or weather tight.
The ONLY COMPONENTS that can be cut are as follows: 650FS - PIPE1000,
650FSROOFCOWL and 13999015 PC TUBE SWAGE X 1.
Ensure all ends are cut square (the use of a mitre box will ensure a clean square cut).
