ABOUT YOUR WATER HEATER
10
HOW DO I KNOW IF THE WATER HEATER IS INSTALLED CORRECTLY?
Installation requirements are shown on pages 45 to 56. 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, and either AS 5601 or AS/NZS 5601.1 as applicable
under local regulations, and all local codes and regulatory authority requirements.
The Gas installations Standards AS 5601 and AS/NZS 5601.1 place limitations on the location of a gas
water heater within a covered area. Refer to “Installation within a Covered Area” on page 47.
Warning: Temperature controllers must not be fitted to this water heater (874 series) if it is installed as
an in-series gas booster with a solar water heater system because water at a temperature much higher than
the controller setting can be delivered. If a solar water heater is installed to an existing water heater
installation, then all controllers must be disconnected and removed.
The pipe work between the solar storage tank (if one is installed) and the in-series gas booster has a
minimum recommended pipe size of DN20, MUST BE of copper and be fully insulated in accordance with
the requirements of AS/NZS 3500.4. The insulation must be weatherproof and UV resistant if exposed. The
insulation must be fitted up to the connections on both the solar storage tank and the in-series gas booster.
