upwards flue diverter
installation guide
The upwards flue diverter is an accessory that can be fitted to an external Rinnai continuous
flow water heater. It is designed to expel combustion products in an upwards direction. The flue
diverter is fitted with screws to the flue terminal
Important
: The flue diverter MUST remain as a permanent fixture as removal could mean the
water heater position no longer complies with AS/NZS 5601.1. All clearances must conform with
AS/NZS 5601.1.
Suitability
•
Externally mounted Rinnai INFINITY water
heaters NOT installed into a recess box.
•
Balconies, patios, or other enclosed areas
where products of combustion can be
rapidly dispersed into the open-air.

Specific applications
Noise reduction, in particular with larger
INFINITY models where the unit is positioned
close to a neighbouring property.
Where there may be an obstruction such
as a tree, fence, wall or other structure, that
even though an INFINITY is installed with
the required clearances, will perform more
efficiently if the flue gases are cleared away
from the obstruction.
Where there are multiple units installed that are
positioned facing each other—there is potential
for other units to suffocate from flue gases of
the unit directly opposite. With an upwards
flue diverter the flue gases can be expelled
upwards and away from the units.
Installation
Installation of the upwards flue diverter varies
depending on the model, this is due to the
different sizes of flue terminal.
Ensure the gas and electricity are turned off
before starting the installation.
Installation of the FDU16, FDU20, and FDU24
1. Remove the INFINITY front cover.
2. Remove and discard the existing foam
housing around the outside of the flue
terminal.
3. Remove the inside three screws from the
flue terminal and set aside.
4. Install the diverter onto the flue terminal,
reinsert screws and tighten.
