ABOUT YOUR WATER HEATER WATER HEATER APPLICATION This water heater is designed for use in a single family domestic dwelling for the purpose of heating potable water. Its use in an application other than this may shorten its life. MODEL TYPE The Rheem® water heater model you have chosen is suitable for outdoor installation only. The model is a high efficiency, quick recovery 8A0 series Rheem Stellar™ 330 stainless steel water heater.
ABOUT YOUR WATER HEATER HOTTER WATER INCREASES THE RISK OF SCALD INJURY This water heater can deliver water at temperatures which can cause scalding. Check the water temperature before use, such as when entering a shower or filling a bath or basin, to ensure it is suitable for the application and will not cause scald injury.
ABOUT YOUR WATER HEATER WARNING This water heater is only intended to be operated by persons who have the experience or the knowledge and the capabilities to do so. This water heater is not intended to be operated by persons with reduced physical, sensory or mental capabilities i.e. the infirm, or by children. Children should be supervised to ensure they do not interfere with the water heater.
ABOUT YOUR WATER HEATER TEMPERATURE ADJUSTMENT This water heater has two forms of water temperature adjustment: A temperature dial on the gas control (thermostat) – this controls the water temperature inside of the storage cylinder. An adjustable water mixing valve – this controls the delivered water temperature from the water heater. Gas Control Temperature Dial The temperature dial is on the gas control, located behind the access cover on the lower front of the water heater.
ABOUT YOUR WATER HEATER Note: When a temperature limiting device is fitted to the hot water pipe work downstream of a Rheem Stellar 330 stainless steel model or if the water heater is installed as part of a circulated flow and return system, the dial of the water heater‟s adjustable water mixing valve must be set on position „5‟. Setting the Adjustable Dial To set the adjustable dial: 1. Ensure the water in the storage cylinder is at the thermostat‟s selected temperature.
ABOUT YOUR WATER HEATER Notes If the adjustable water mixing valve is set on the lowest setting (position „1‟) and the delivered water temperature is still too hot, then reduce the thermostat setting on the gas control and wait twenty four (24) hours before repeating the procedure above. Refer to “Gas Control Temperature Dial” on page 7 for information on adjusting the thermostat setting. The delivered water temperature should be checked periodically at a hot water tap.
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 43). 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 DOES THE WATER CHEMISTRY AFFECT THE WATER HEATER? The water heater is suitable for most public water supplies, however some water chemistries may have detrimental effects on the water heater, its components and fittings. Refer to “Water Supplies” on page 15. If you are in a known harsh water area or you are not sure of your water chemistry, have your water checked against the conditions described on pages 15 to 18.
REGULAR CARE MINOR SIX MONTH MAINTENANCE It is recommended minor maintenance be performed every six (6) months by the dwelling occupant. The minor maintenance includes: Operate the easing lever on the temperature pressure relief valve. It is very important you raise and lower the lever gently. Refer to “Temperature Pressure Relief Valve” on page 14. Warning: Exercise care to avoid any splashing of water, as water discharged from the drain line will be hot.
REGULAR CARE MAJOR FIVE YEAR SERVICE It is recommended a major five (5) year service be conducted on the water heater. Warning: Servicing of a gas water heater must only be carried out by qualified personnel. Phone Rheem Service or their nearest Accredited Service Agent. Note: The five (5) year service and routine replacement of any components, such as the relief valve(s), are not included in the Rheem warranty. A charge will be made for this work.
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 Running” on page 20).
WATER SUPPLIES This water heater must be installed in accordance with this advice to be covered by the Rheem warranty. This water heater is manufactured to suit the water conditions of most public reticulated water supplies. However, there are some known water chemistries which can have detrimental effects on the water heater and its operation and / or life expectancy. A list of postcodes is available on the Rheem website (www.rheem.com.
WATER SUPPLIES CHLORIDE AND PH In a high chloride water supply, the water can corrode stainless steel parts and cause them to fail. Where the chloride level exceeds 250 mg / L the Rheem warranty does not apply to a stainless steel cylinder. pH is a measure of whether the water is alkaline or acid. In an acidic or very alkaline water supply, the water can attack stainless steel parts and cause them to fail. Where the pH is less than 6.0 or greater than 9.
WATER SUPPLIES SATURATION INDEX The saturation index (SI) is used as a measure of the water‟s corrosive or scaling properties. In a corrosive water supply, the water can attack copper parts and cause them to fail. In a scaling water supply calcium carbonate is deposited out of the water onto any hot metallic surface. Where the saturation index exceeds +0.40, the water is very scaling.
WATER SUPPLIES TOTAL DISSOLVED SOLIDS The stainless steel cylinder of the water heater is only covered by the Rheem warranty when the total dissolved solids (TDS) content in the water is less than 600 mg / L. Note: Some water analysis reports may state the conductivity of the water rather than the level of total dissolved solids. Conductivity, measured in microsiemens per centimetre (µS / cm), is directly proportional to the TDS content of the water.
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 water usage.
SAVE A SERVICE CALL WATER NOT HOT ENOUGH Has your hot water usage increased? You may find that due to heavy hot water usage the water temperature may be lower than normally expected. Is the adjustable water mixing valve setting correct? Check the setting of the adjustable water mixing valve. If the temperature of the water being delivered is too low for your requirements, then adjust the setting to a higher number. Refer to “Adjustable Water Mixing Valve” on page 7.
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 32) 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.
SAVE A SERVICE CALL HIGHER THAN EXPECTED GAS BILLS Should you at any time, feel your gas bill is higher than expected, we suggest you check the following points: Is the relief valve running excessively? Refer to “Temperature Pressure Relief Valve Running” on page 20. Is one outlet (especially the shower) using more hot water than you think? Refer to “Not Enough Hot Water (or No Hot Water)” on page 19.
INSTALLATION THIS WATER HEATER IS FOR OUTDOOR INSTALLATION ONLY. 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 affixed behind the access cover on the water heater). INSTALLATION STANDARDS The water heater must be installed: by a qualified person, and in accordance with the installation instructions, and in compliance with Standards AS/NZS 3500.4, AS 5601 or AS/NZS 5601.
INSTALLATION WATER HEATER LOCATION The water heater should be installed close to the most frequently used outlet and its position chosen with safety and service in mind. Make sure people (particularly children) will not touch the flue terminal. The flue terminal must be clear of obstructions and shrubbery. Clearance must be allowed for servicing of the water heater. The water heater must be accessible without the use of a ladder or scaffold.
INSTALLATION The water heater must not be installed in an area with a corrosive atmosphere where chemicals are stored or where aerosol propellants are released. Remember the air may be safe to breathe, but when it goes through a flame, chemical changes take place which may attack the water heater. The water heater must be located to ensure that the location of the flue terminal complies with the requirements of AS 5601 or AS/NZS 5601.1, as applicable under local regulations.
INSTALLATION 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 cold water connection diagram on page 32. 330 Model Relief valve setting 1400 kPa Expansion control valve setting * 1200 kPa Max. mains supply pressure With expansion control valve 960 kPa Without expansion control valve 1120 kPa * Expansion control valve not supplied with the water heater.
INSTALLATION FLASHING KIT A Flashing Kit (PN AQ1064105) for a recessed installation is available from Rheem. It is sold separately to the water heater. The Flashing Kit must not be installed within a 100 mm wide vertical strip either side of the cold water inlet, hot water outlet and temperature pressure relief valve. When attaching a Flashing Kit to the water heater jacket, use of self-drilling screws with a maximum length of 13 mm.
INSTALLATION HOT WATER DELIVERY This water heater can deliver water at temperatures which can cause scalding. It is necessary and we recommend that a temperature limiting device be fitted between the water heater and the hot water outlets in any ablution and public areas such as a bathroom, ensuite or public amenities, to reduce the risk of scalding.
INSTALLATION 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 29. The dial of the Rheem Stellar 330 stainless steel water heater‟s adjustable water mixing valve must be set on position „5‟.

CONNECTIONS – PLUMBING GAS INLET The gas connection is made through the left hand side near the access cover to the gas control. The pipe work must be cleared of foreign matter before connection and purged before attempting to light the water heater. An isolation valve and disconnection union must be installed to allow servicing and removal of the water heater. Remove the yellow warning label from the gas control after connecting the gas supply pipe.
COMMISSIONING TO FILL AND TURN ON THE WATER HEATER The gas pilot or burner must not be lit until the water heater is filled with water. Open all of the hot water taps in the house (don‟t forget the shower). Open the cold water isolation valve fully to the water heater. Air will be forced out of the taps. Close each tap as water flows freely from it. Check the pipe work for leaks. Open the gas isolation valve fully. Check the gas pipe work for leaks. Test the gas supply pressure to the water heater.
COMMISSIONING GAS INLET PRESSURE IMPORTANT – CHECK the gas supply pressure at the inlet to the water heater with the water heater and all other gas burning appliances in the premises operating (burners alight). The minimum gas supply pressure for Natural Gas is 1.13 kPa. If this minimum cannot be achieved, it may indicate the meter or the gas line to the water heater is undersized.
COMMISSIONING BURNER GAS PRESSURE TESTING AND ADJUSTMENT The burner gas pressure must be checked and adjusted (if required) as part of the commissioning procedure. Refer to Gas Details in the table on page 31 or check the rating label of the water heater for the burner test point pressure with the burner operating. To check and adjust the burner gas pressure of the water heater: 1. Remove the access cover. 2.
COMMISSIONING 8. Natural gas model: Remove the temperature dial from the front of the gas control by using a small flat bladed screwdriver to carefully lever the dial and pull away from the gas control. Using a small flat bladed screwdriver, rotate the burner pressure adjustment screw (P.R.ADJ) clockwise to increase the burner pressure or anticlockwise to decrease the burner pressure until the manometer reads 1.0 kPa. After adjusting the burner gas pressure refit the temperature dial.
LIGHTING THE WATER HEATER FOR YOUR SAFETY READ BEFORE LIGHTING Warning: This gas water heater is designed to operate reliably and safely as long as the operating instructions are followed exactly. You must comply with these lighting instructions at every stage. Make sure the water heater is filled with water and the water supply is on, otherwise serious damage to the stainless steel cylinder and plastic components may occur.
