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 5601.1, as applicable under local

regulations, and all local codes and regulatory authority requirements.

In New Zealand the installation must also conform with NZS 5261, as applicable under local regulations, and

the New Zealand Building Code.

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

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.

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.

The 884 series of water heater may be installed as an in-series gas booster to a solar water heater. For

information relating to the function and operation of the solar water heater, refer to the Owner’s Guide and

Installation Instructions supplied with the solar water heater.

Note: The 886 series water heater is marked “THIS APPLIANCE DELIVERS WATER NOT EXCEEDING

50°C IN ACCORDANCE WITH AS 3498” on the front panel. This model;

• must not be installed as an in-series gas booster to a solar water heater, as water temperature greater

than 50°C can be delivered from the water heater contravening its compliance to AS 3498.

• must not be installed with a Water Star water heater as water temperature greater than 50°C can be

delivered from the system.

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

potable water. When this water heater is used as an in-series gas booster to a solar water heater, it can

satisfy this AS 3498 requirement provided it is energised, the booster preset outlet temperature setting is

70°C or higher and a remote temperature controller is not used.
