HOW YOUR WATER HEATER WORKS 11 MAINS PRESSURE The water heater is designed to op erate at mains pressure by connec ting directly to the mains water supply. If the mains supply pressu re in your area exceeds that shown on page 19, a pr essure limiting valve must be fitted. The supply pressure should be greater than 3 50 kPa for true mains pressure o[...]

12 REGULAR CARE TEMPERATURE PRESSURE RELIEF VALVE This valve is near the top of the wa ter 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 approxim ately 1/50 of its volume. Continuous leakage o[...]

13 SAVE A SERVICE CALL Check the items below before making a service call. You will be charged for attending t o any condition or fault that is not related to manufacture or failure of a part.
