INSTALLATION – WATER HEATER
51
INSTALLATION WITHIN A COVERED AREA
The water heater must be located such that the installation meets the requirements of AS/NZS 5601.1. There
must be sufficient ventilation so the water heater has an adequate supply of combustion air and the flue
products are dispersed safely. It is the licensed installer’s responsibility to ensure the installation complies with
the relevant sections of the prevailing Gas installations Standard.
Installation of this water heater is permitted within a covered area open on at least two sides, if its flue terminal
is located to ensure a free flow of air across it is achieved.
AS/NZS 5601.1 also allows the installation of
a continuous flow gas water heater within a
covered area open on one side only if the flue
terminal is within 500 mm of the opening, is
discharging in the direction of the opening,
there are no openings into the building along
the wall within the 500 mm distance and the
terminal is located to ensure a free flow of air
across it is achieved.

826NF or T26NF model (AU only) fitted with a
Rheem Flue Terminal Diverter (kit number
299287) in accordance with its installation
instructions, can be installed to meet this
requirement.
