ABOUT YOUR WATER HEATER TEMPERATURE ADJUSTMENT The temperature adjusting dial is on the gas valve, located behind the access cover on the lower front of the water heater. A setting of ‘6’ will normally maintain the water temperature at about 60 °C. Each number represents a temperature difference of approximately 6 °C. To increase the water temperature to 65 °C, turn the gas control knob anticlockwise to a setting of ‘7’. Refer to “Hotter Water Increases the Risk of S

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 TEMPERATURE LIMITING VALVE A RheemPlus water heater is fitted with a temperature limiting valve at the hot water outlet. The valve is set to deliver water not exceeding 50 °C. The valve should be checked for performance every twelve months. This can be performed by measuring the water temperature from a hot tap with a thermometer. If the water is being delivered at a temperature exceeding 50 °C, phone your nearest Rheem Service Department or Accredited Service Agent to arr

WATER TEMPERATURE TOO HIGH A RheemPlus water heater is fitted with a temperature limiting valve set to deliver water not exceeding 50 °C. If the water is being delivered at a temperature exceeding 50 °C, phone your nearest Rheem Service Department or Accredited service Agent to arrange for an inspection.

SAVE A SERVICE CALL EXPANSION CONTROL VALVE RUNNING If an expansion control valve is fitted in the cold water line to the water heater (refer to page 22) it may discharge a small quantity of water instead of the temperature pressure relief valve on the water heater. The benefit is that energy is conserved as the discharged water is cooler. 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 norma

INSTALLATION The water heater is to be installed at ground level on a concrete or brick plinth (fire proof base) and must stand vertically upright with the back of the water heater against an external wall or alternatively against a fireproof screen extending at least 500 mm above, below and either side the flue terminal. Failure to observe this precaution can cause problems in high wind areas. The water heater must be secured to the wall or screen using the brackets provided. A secondary

INSTALLATION SADDLING - PIPE WORK To prevent damage to the cylinder when attaching pipe clips or saddles to the water heater jacket, we recommend the use of self-drilling screws with a maximum length of 12 mm. Should pre drilling be required, extreme caution must be observed when penetrating the jacket of the water heater. Note: Damage to the cylinder as a result of saddling to the jacket will void the warranty. 19
