HOW YOUR WATER HEATER WORKS 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

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 Run

REGULAR CARE 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. Water will flow from its drain line during the heating period. 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

SAVE A SERVICE CALL TEMPERATURE PRESSURE RELIEF VALVE RUNNING • Normal Operation It is normal and desirable this valve allows a small quantity of water to escape during the heating cycle. However, if it discharges more than a bucket full of water in 24 hours, there may be another problem. • Continuous dribble Try gently raising the easing lever on the relief valve for a few seconds (refer to “Temperature Pressure Relief Valve” on page 8). This may dislodge a small particle of

SAVE A SERVICE CALL CAN’T LIGHT THE PILOT FLAME • Is there gas to the water heater? Check the gas isolation valve on the gas supply line is open. • Is there a normal gas supply to the rest of the premises? Try lighting another gas appliance to check. If there is no gas, call the gas supplier. WATER HEATER APPEARS TO BE LEAKING When the water heater is first lit, or after a large usage of hot water, condensation may form on the burner of the water heater. This is quite normal, e
