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%).

WATER HEATER LOCATION

An indoor model must be installed indoors and an outdoor model must be installed outdoors, except where a 631 275 model water heater is installed indoors with a Rheem room sealed installation kit. The water heater should be installed either 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 (particularly children) will not touch the flue outlet. 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. Make sure the temperature pressure relief valve lever is accessible and the front covers or panels, thermostats and burner can be removed for service.

You must be able to read the information on the rating plate. If possible leave headroom of one water heater length so the anode can be inspected or replaced. Remember you may have to take the entire water heater out later for servicing.

The installation must comply with the requirements of AS/NZS 3500.4, AS/NZS 3000, AS 5601 and all local codes and regulatory authority requirements. In New Zealand, the installation must conform with NZS 5261 Code of Practice for Installation of Gas Burning Appliances and the New Zealand Building Code.

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 22 and 23. For multiple water heater installations, follow the instructions on pages 32 to 36.
