Victorian Installers
Notice to Victorian Installers from the Victorian Plumbing Industry Commission if this solar water heater is
installed in a new Class 1 dwelling in the State of Victoria. The system model number is to be recorded on
the Certificate of Compliance. It is also a requirement to provide the householder with permanent
documentation recording the system model number exactly as it is shown in the „List of systems capable of
complying with the regulations‟ published by Sustainability Victoria (see www.sustainability.vic.gov.au). This
documentation may be in the form of an indelible label adhered to the solar storage tank, or other suitable
form placed in an accessible location, such as the meter box, for later inspection.
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.
This solar water heater is designed to be installed with either a Vulcan continuous flow 244 620 in-series gas
booster mounted onto the storage tank or installed remotely or a Vulcan continuous flow 244 627 in-series
gas booster installed remotely.
Warning: A 627 model in-series gas booster cannot be mounted on the solar storage tank and may only
be installed remotely. The size and weight of the gas booster may cause the solar storage tank to topple
over.
The solar water heater may be installed with another suitable type of remotely installed in-series continuous
flow or storage booster. If the in-series water heater is other than a Vulcan continuous flow 244 620 or
244 627 in-series gas booster, then the references to the in-series gas booster in this guide may not be
applicable to the installation. For information relating to the function and operation of the in-series water
heater, refer to the Owners Guide and Installation Instructions supplied with the water heater.
Note: AS 3498 requires that a water heater provides the means to inhibit the growth of Legionella bacteria in
potable water. If this water heater is installed with an continuous flow in-series gas booster, then this
requirement of AS 3498 can be satisfied provided the booster is energised, its preset outlet temperature
setting is 70°C or higher and a remote temperature controller is not used.
If this water heater is installed with an in-series storage booster, then this requirement of AS 3498 can be
satisfied provided the storage booster is energised and its thermostat setting is 60°C or higher.
SOLAR WATER HEATER STORAGE TANK LOCATION
The solar storage tank is suitable for indoor or outdoor
installation. If an in-series gas booster is mounted onto the
storage tank, then the installation must be outdoors. The solar
storage tank should be installed close to the most frequently used
outlet and its position chosen with safety and service in mind.
Make sure people (particularly children) will not touch the flue
terminal of an in-series gas booster. The flue terminal and air inlet
must be clear of obstructions and shrubbery.
Consideration must also be given to the position of the solar
storage tank in relation to the solar collector. There are limitations
on both the maximum length of the solar hot and solar cold pipes
and the maximum height between the solar storage tank and the
solar collector. Refer to “Solar Collector Location” on page 33 and
to “Pipe Lengths” on page 34.
Clearance must be allowed for servicing of the solar storage tank and in-series gas booster. The solar
storage tank must be accessible without the use of a ladder or scaffold. Make sure the temperature pressure
relief valve lever is accessible and the front panel and front covers can be removed for service.
