SAVE A SERVICE CALL Check the items below before making a service call. You will be charged for attending to any condition or fault that is not related to the manufacture or failure of a part. NOT ENOUGH HOT WATER (OR NO HOT WATER) •... - Page 23 SAVE A SERVICE CALL TEMPERATURE PRESSURE RELIEF VALVE OR EXPANSION CONTROL VALVE RUNNING • Normal Operation It is normal and desirable the temperature pressure relief valve or expansion control valve (if fitted) allows a quantity of water to escape during the heating cycle. This quantity should be equal to approximately 1/50 of the hot water used, as water expands by this volume when heated.
- Page 24 SAVE A SERVICE CALL 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 and grille at the front of the water heater. This is quite normal, especially in winter months and will dry off as the water is heated.
