Page 4: About Your Water Heater
® The Rheem Heavy Duty Gas water heater model you have chosen is either a 265 litre or 275 litre indoor or outdoor quick recovery water heater. Water is stored in a vitreous enamel lined steel cylinder and heated by a gas burner located under the cylinder. - Page 5 Warning: For continued safety of this water heater it must be installed, operated and maintained in accordance with the Owner‟s Guide and Installation Instructions. The Rheem warranty may not cover faults if relief valves or other safety devices are tampered with or if the installation is not in accordance with these instructions.
- Page 6 ABOUT YOUR WATER HEATER Do not store flammable or combustible materials near the water heater. Flammable liquids (such as petrol), newspapers and similar articles must be kept well away from the water heater and the draught diverter or flue terminal. Gases from some aerosol sprays, stain removers and household chemicals become corrosive when drawn into a flame.
- Page 7 ABOUT YOUR WATER HEATER HOW DO I KNOW THE WATER HEATER IS INSTALLED CORRECTLY? Installation requirements are shown on pages 24. The water heater must be installed: by a qualified person, and in accordance the installation instructions, and in compliance with Standards AS/NZS 3500.4, AS 5601 or AS/NZS 5601.1, as applicable under local regulations, and all local codes and regulatory authority requirements.

Page 17: Installation
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) Note: In Australia, natural gas models can be connected to SNG, however the hourly gas consumption may be reduced (typically by 10%). - Page 18 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. For a single water heater installation, follow the diagrams on pages 24.
- Page 19 INSTALLATION OUTDOOR INSTALLATION The water heater is to be installed at ground level on a concrete or brick plinth or other fireproof base as approved by the local authority. The water heater must also stand vertically upright with the back of the water heater against or within 25 mm of an external wall or alternatively against a fireproof screen extending at least 500 mm above, below and either side the flue terminal.
- Page 20 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 bathrooms, ensuites or public amenities, to reduce the risk of scalding.
- Page 21 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.
- Page 22 ANODE The vitreous enamel lined 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 2500 mg/L and when the correct colour coded anode is used.
