ABOUT YOUR WATER HEATER MODEL TYPE ® Congratulations for choosing a Rheem Heavy Duty Gas water heater. The model you have chosen is a quick recovery water heater. HOW HOT SHOULD THE WATER BE? The water heater features a user adjustable thermostat, which allows you to personally choose the most suitable temperature for your hot water needs. maximum thermostat Refer to “Temperature Adjustment” on setting page 4. minimum recommended stored water temperature To meet the requ

ABOUT YOUR WATER HEATER 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 Scald Injury” on page 4. WARNING This water heater is not intended to be operated, adjusted or tampered with by young children or infirm persons. Young children should be supervised to ensure they do not interfere with the water heater. SAFETY This water heater is supplied with a thermostat, an over-temperature

ABOUT YOUR WATER HEATER TO TURN OFF THE WATER HEATER If it is necessary to turn off the water heater: • Shut down the gas control (refer to “Close Down Procedure” on page 36). • Close the gas isolation valve at the inlet to the gas control. • Close the cold water isolation valve at the inlet to the water heater. TO TURN ON THE WATER HEATER • Open the cold water isolation valve fully at the inlet to the water heater. • Open the gas isolation valve fully at the inlet to the gas control.

ABOUT YOUR WATER HEATER ANODE PROTECTION The anode(s) installed in your water heater will slowly dissipate whilst protecting the cylinder. The life of the water heater cylinder may be extended by arranging for an authorised person to inspect the anode(s) and replace if required. The suggested time after installation when the anode(s) should be inspected is: Heavy Duty 7 years For softened water supplies or in areas of poor water quality, it is recommended the anode(s) be inspected

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 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 manufacture or failure of a part. NOT ENOUGH HOT WATER (OR NO HOT WATER) • Are you using more hot water than you think? Is one outlet (especially the shower) using more hot water than you think? Very often it is not realised the amount of hot water used, particularly when showering. Carefully review the family’s hot wate

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. 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 th

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 23) 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. 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 t

INSTALLATION THIS WATER HEATER IS NOT SUITABLE FOR POOL HEATING. Check the water heater is suitable for the gas type available (refer to the rating label on the water heater). WATER HEATER LOCATION An indoor model must be installed indoors and an outdoor model must be installed outdoors. The water heater should be installed close to the most frequently used outlets or with a circulated flow and return system and its position chosen with safety and service in mind. Make sure people

INSTALLATION INDOOR INSTALLATION A secondary flue must be installed with an indoor water heater to discharge combustion products outside the building. The flue must be self supporting and not impose a load on the water heater. Use a slip joint or similar to allow for disconnection. There must be a vertical rise of 600 mm from the draught diverter before changing direction. The flue design and installation must comply with AS 5601. For indoor models the distances set out in the diagram

INSTALLATION OUTDOOR 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 500mm above, below and either side of the flue terminal. Failure to observe this precaution can cause problems in high wind areas. A secondary flue is not required. As a guide the following re

INSTALLATION Two Temperature Zones Using a Temperature Limiting Device CIRCULATED HOT WATER FLOW AND RETURN SYSTEM If a Rheem water heater is to be installed as part of a circulated hot water flow and return system, a storage water heater able to provide a hot water outlet temperature of at least 60 °C must be used. Note: The thermostat must always be set to at least 60 °C. Refer to the diagram on page 19. Temperature Limiting Device A temperature limiting device cannot be instal
