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 either a Rheemglas
850 series or RheemPlus
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 choose the most
suitable temperature for your hot water needs. Refer
"Temperature Adjustment"
to
A RheemPlus water heater is temperature limited to
supply water not exceeding 50°C directly to fixtures
used primarily for personal hygiene.
To meet the requirements of the National Plumbing
Standard the temperature of the stored water must not
be below 60°C.
Note: AS 3498 requires that a water heater provides
the means to inhibit the growth of Legionella bacteria
in potable water. This water heater can satisfy this
AS 3498 requirement 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.
