INSTALLATION – WATER HEATER
THIS WATER HEATER IS FOR INDOOR 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 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 5601.1, as applicable under local
regulations, and all local codes and regulatory authority requirements.
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 862 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: 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 booster for 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 that a remote temperature controller is not used.
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. If this water heater is part of a solar water
heater system, it should also be installed close to the solar
storage tank. Make sure people (particularly children) will not
touch the flue outlet. The flue outlet and air inlet must be
clear of obstructions.
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 entire front panel can be
removed for service. You must be able to read the
information on the rating plate. Remember you may have to
take the entire water heater out later for servicing.
There are also special requirements in AS 5601 and AS/NZS 5601.1 for water heaters installed in a garage,
an enclosed space and other locations. Remember all local authorities have regulations about putting water
heaters into roof spaces.
