INSTALLATION – WATER HEATER
47
INSTALLATION WITHIN A COVERED AREA
The water heater must be located such that the installation meets the requirements of either AS 5601 or
AS/NZS 5601.1 as applicable under local regulations. 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.
A Rheem 874 or 876 series 12NF or 16NF model fitted with a Rheem Flue Terminal Diverter (kit number
299881) in accordance with its installation instructions, can be installed to meet this requirement.
A Rheem 874 or 876 series 12NF or 16NF model water heater can also be installed on a side wall within a
covered area (open on one side only), and meet the installation requirements of AS 5601 and
AS/NZS 5601.1, if it is fitted with a Rheem Flue Terminal Diverter (kit number 299281) and positioned so that
the outlet of the Flue Terminal Diverter is level with or beyond the outer edge of the side wall of the covered
area.
A Rheem Flue Terminal Diverter can be fitted to a Rheem 874 or 876 series 12NF or 16NF model installed in
a recess box. Refer to
“Recess Installation” on page 48.
