REGULAR CARE

TEMPERATURE PRESSURE RELIEF VALVE

This valve is near the top of the water heater and is essential for its

safe operation. It is possible for the valve to release a little water

through the drain line during each heating period. This occurs as the

water is heated and expands by approximately 1/50 of its volume.

Continuous leakage of water from the valve and its drain line may

indicate a problem with the water heater (refer to “Temperature

Pressure Relief Valve Running” on page 21).

Warning: Never block the outlet of this valve or its drain line for

any reason.

Operate the easing lever on the temperature pressure relief valve

once every six months. It is very important you raise and lower

the lever gently.

Warning: Failure to do this may result in the water heater

cylinder failing.

If water does not flow freely from the drain line when the lever is

lifted, then the water heater should be checked by Rheem Service

or their nearest Accredited Service Agent.

The temperature pressure relief valve should be checked for

performance or replaced at intervals not exceeding 5 years, or more

frequently in areas where there is a high incidence of water deposits

(refer to “Water Supplies” on page 17).

EXPANSION CONTROL VALVE

In many areas, including South Australia, Western Australia and

scaling water areas, an expansion control valve is fitted to the cold

water line to the water heater. The expansion control valve may

discharge a small quantity of water from its drain line during the

heating period instead of the temperature pressure relief valve on

the water heater.

Operate the easing lever on the expansion control valve once every six months. It is very important you

raise and lower the lever gently. The expansion control valve should be checked for performance or

replaced at intervals not exceeding 5 years, or more frequently in areas where there is a high incidence of

water deposits.

SERVICING

For safe and efficient operation, the water heater should be serviced annually by Rheem Service or their

nearest Accredited Service Agent. Only genuine replacement parts should be used on this water heater.

Warning: Servicing of a gas water heater should only be carried out by authorised personnel.
