ABOUT YOUR WATER HEATER

WATER HEATER APPLICATION
This water heater is designed for use in a single family domestic dwelling for the
purpose of heating potable water. Its use in an application other than this may
shorten its life.
MODEL TYPE
®
The Rheem water heater model you have chosen is
suitable for outdoor installation only. The model is a high
efficiency, quick recovery 850 series Stellar™ natural
gas water heater.
Water is stored in a vitreous enamel lined steel cylinder
and heated by a gas burner located under the cylinder.
The heat produced by the burner is transferred to the
water through the base, top and wall of the cylinder and
through the wall of a flue pipe which passes through the
centre of the cylinder. A flue baffle in this flue ensures the
efficiency of the water heater is correct. The gas supply
to the burner is controlled by the thermostat so the water
is heated to a constant temperature. Automatic safety
controls are fitted to the water heater to provide safe and
efficient operation.
HOW HOT SHOULD THE WATER BE?
The water heater features a user adjustable
thermostat, which allows you to personally
choose the most suitable temperature for your
hot water needs. Refer to
Adjustment"
on page 14.
To meet the requirements of the National
Plumbing Standard the temperature of the
stored water must not be below 60°C.
Note: Australian Standard AS 3498 and New
Zealand Building Code Clause G12 requires
that a water heater provides the means to
inhibit the growth of Legionella bacteria in
potable water. This water heater can satisfy
these AS 3498 and Clause G12 requirements
provided it is operating and the thermostat
setting is 60°C or higher, including when it is
used as an in-series booster water heater for a
solar water heater.
