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 311 series

Rheemglas

, 314 series RheemPlus™ or 811 series

Optima™ water heater. Optima models have an extended

manufacturer‟s warranty (refer to page 41).

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 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 to “Temperature Adjustment” on page 5.

A RheemPlus water heater is temperature limited to

deliver water not exceeding 50°C.

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.
