REGULAR CARE

PRESSURE RELIEF VALVE

This valve is located in the in/out header 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 “Pressure Relief Valve Running” on page 10).

WARNING: Never block the outlet of this valve or its drain line for any reason.

Operate the easing lever on the 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 heat exchanger failing.

If water does not flow freely from the drain line when the lever is lifted, then the water heater should be checked by your installing plumber, or phone your nearest Rheem Service Department or Accredited Service Agent.

The 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 39).

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 heating system. The expansion control valve may discharge a small quantity of water from its drain line during the heating period instead of the 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.

STORAGE TANKS (If fitted)

Refer to the owners guide and installation instructions supplied with the storage tank for details on regular care required.

SERVICE

For efficient operation the water heater should be serviced annually by your nearest Rheem Service Department or 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.
