4 ABOUT YOUR WATER HEATER MODEL TYPE Congratulations for choosing a Rheem ® Heavy Duty Gas water heater. The model you have chosen is either a 265 litre or 275 litre indoor or outdoor quick recovery water heater. HOW HOT SHOULD THE WATER BE? The water heater has a maximum temperature setting of 82 ° C and a minimum temperature setting of 60 ° C.
ABOUT YOUR WATER HEATER 5 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. The removal of the access cover(s) will expose 240 V wiring.
ABOUT YOUR WATER HEATER 6 This water heater is supplied with a thermostat, an over-temperature cut-out, and a combination temperature pressure relief valve. These devices must not be tampered with or removed. The water heater must not be operated unless each of these devices is fitted and is in working order.
ABOUT YOUR WATER HEATER 7 DOES THE WATER QUALITY AFFECT THE WATER HEATER? The water heater is suitable for most public water supplies, however some water qualities may have detrimental effect s on the cylinder and fittings. If you are in a known harsh water area you must read page 46 .
8 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 cylin der.
9 REGULAR CARE TEMPERATURE PRE SSU RE R ELIEF VAL VE 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.
REGULAR CARE 10 SERVICING For efficient operation the water heater should be serviced annually by your nearest Rheem Service Department or their Accredited Service Agent. Only genuine replacement parts should be used on this water heater. Warning : Servicing of a gas water heater should only be carried out by authorised personnel.
11 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 n ot related to manufacture or failure of a part.
SAVE A SERVICE CALL 12 WATER HEATER NOT OPERATING The ignition system may have ‘locked out’. To reset the water heater, switch the electrical supply off at the isolating switch, wait ten seconds then switch on again.
SAVE A SERVICE CALL 13 TEMPERATURE PRES SU RE RELI EF VAL VE RUN NI NG • Normal Operation It is normal and desirable that this valve allows a small quantity of water to escape during the heating cycle. However, if the discharge is deemed excessive (more than 2% of hot water used), there may be another problem.
SAVE A SERVICE CALL 14 WATER HEATER APPEARS TO BE L EAKING When the water heater is first lit or after a large usage of hot water, condensation may form on the burner of the water heater. This is quite normal, especially in winter months and will dry off as the water is heated.
15 INSTALLATION THIS WATER HEATER I S 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) Note: In Australia, natural gas models can be connected to SNG, however the hourly gas consumption may be reduced (typically by 10%).
INSTALLATION 16 INDOOR INSTALLATION A secondary flue must be installed with an indoor water heater to d ischarge 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.
INSTALLATION 17 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.
INSTALLATION 18 MAINS WATER SUPPLY Where the mains water supply pressure exceeds that shown in the table below, an approved pressure limiting valve is required and should be fitted as shown in the installation diagram (refer to installation diagram on page 25 ) .
INSTALLATION 19 Two Temperature Zon es Using a Temperature Limiting De vice CIRCULATED HOT WATER FLOW AND RETUR N SYSTEM If a Rheem water heater is to be insta lled as part of a circulated hot water flo w and return system, a storage water heater able to provide a hot w ater outlet temperature of at least 60 ° C must be used.
INSTALLATION 20 These conditions may result in either water at a temperature exceeding the requirements of AS/NZS 35 00.4 being delivered to the hot water outlets in the ablution areas, or the device closing completely and not delivering water at all, or the device failing.
INSTALLATION 21 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.
