INSTALLATION

THIS WATER HEATER IS NOT SUITABLE FOR POOL HEATING

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/NZS 3000 and all local codes and regulatory authority

requirements.

In New Zealand the installation must also conform with the New Zealand Building Code.

All packaging materials must be removed from the water heater prior to its installation. This includes the

removal of the cardboard base of the carton from the underside of the water heater.

WATER HEATER APPLICATION

This water heater is designed for the purpose of heating potable water. Its use in an application other than

this may shorten its life.

If this water heater is to be used where an uninterrupted hot water supply is necessary for the application or

business, then there should be redundancy within the hot water system design. This should ensure the

continuity of hot water supply in the event that this water heater was to become inoperable for any reason.

We recommend you provide advice to the system owner about their needs and building backup redundancy

into the hot water supply system.

Note: AS 3498 requires that a water heater provides the means to inhibit the growth of Legionella bacteria in

potable water. This water heater can satisfy this AS 3498 requirement provided it is energised and the

thermostat setting is 60°C or higher, including when it is used as an in-series booster water heater for a solar

water heater.

WATER HEATER LOCATION

This water heater is suitable for either outdoor or indoor installation. Whether located outdoor or indoor, 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.

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 cover,

thermostats and heating units 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 height so the anode can be inspected or replaced. Remember

you may have to take the entire water heater out later for servicing.

The water heater is to be installed at ground or floor level and must stand

vertically upright on a stable base as acceptable to local authorities. The base

of the water heater is made of corrosion resistant material, and it may be

placed directly in contact with the supporting surface. It is not necessary to

allow for free air circulation under the base of the water heater.

Note: The water heater should not be placed in direct contact with a concrete surface that is less than two

months old and not fully cured as this may attack the metal coating of the water heater base. A moisture

barrier should be used between the two surfaces in this instance.

Alternatively, an 050 model may be hung on a wall capable of taking the weight of the filled water heater. A

bracket kit is available from Rheem. Refer to the instructions supplied with the kit.

Remember all local authorities have regulations about putting water heaters into roof spaces.

For a single water heater installation, follow the diagram on page 19. For multiple water heater installations,

follow the instructions on pages 24 to 27.
