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 ‘VEET Product Register’ published by the
Essential Services Commission in Victoria (see www.veet.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 backup 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 has an in-series gas booster which can satisfy this AS 3498 requirement
provided the gas booster is energised, the booster preset outlet temperature setting is 70°C or higher and a
remote temperature controller is not used.
SOLAR WATER HEATER STORAGE TANK LOCATION
The solar storage tank is suitable for outdoor installation only. 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. 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 collectors.
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 collectors. Refer to “Solar Collector Location” on page 28,
to “Pipe Lengths” on page 30 and to “Maximum Height To Collectors” on page 32.
Clearance must be allowed for servicing of the solar storage
tank and 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.
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 remove the entire solar storage tank later for
servicing.
The solar storage tank is to be installed at ground or floor
level and must stand vertically upright on a stable base as
acceptable to local authorities.
Note: It is important for the solar storage tank to be orientated vertically upright in order for the falling film of
closed circuit fluid to operate efficiently.
The top of the solar storage tank must be a minimum of 500 mm below the bottom of the solar collectors for
the system to operate correctly.
The water heater must not be installed in an area with a corrosive atmosphere where chemicals are stored or
where aerosol propellants are released. Remember the air may be safe to breathe, but when it goes through
a flame, chemical changes take place which may attack the water heater.
A secondary flue is not required. The water heater must not be installed indoors or in a confined space.
