HOW YOUR WATER HEATER WORKS The water heater consists of a gas burner, a combustion chamber lined with refractory tiles and a heat-exchanger made of finned copper tubes. Hot flue gases from the burner pass between the fins on the heat exchanger tubes and heat is transferred first to the fins and then by conduction into the water. Baffles are placed between the tubes to control the flow of the hot flue gases and ensure efficient operation of the water heater. The refractory tiles insulat

HOW YOUR WATER HEATER WORKS 147 MODELS On/Off Operation 147 On/Off models are fitted with an electronic thermostat that operates the gas control by switching its power on and off, so a constant temperature is maintained. The thermostat is mounted on the control panel of the water heater and the protective over temperature cut out is mounted inside the lower front cover of the water heater. There is no need to switch the water heater off when it is not in use. The thermostat is fully auto

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).
