INSTALLATION – SOLAR STORAGE TANK
23
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. The top of the solar storage tank must be a
minimum of 500 mm below the bottom of the solar collector for
the system to operate correctly.
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 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.
If an in-series gas booster is mounted to the solar storage tank, the water heater must not be installed
indoors or in a confined space. A secondary flue is not required.
The water heater must be located to ensure that the location of
the flue terminal complies with the requirements of AS 5601 or
AS/NZS 5601.1, as applicable under local regulations. As a guide
the following requirements are extracted from the Gas
Installations Standard. The distances are measured along the
wall behind the water heater.
At least 300 mm between the top of the flue terminal and the
eaves.
At least 300 mm (20 litre models) or 500 mm (27 litre
models) between the flue terminal and the edge of any
opening into the building, such as an openable door or
window, measured horizontally*.
At least 1500 mm between the top of the flue terminal and
the edge of any opening into the building, such as an
openable window, measured vertically.
At least 300 mm between the flue terminal and a return wall
or external corner, measured horizontally*.
At least 1500 mm between the flue terminal and any opening
into a building, in the direction of the flue discharge.
At least 500 mm between the flue terminal and a fence, wall
or other obstruction, in the direction of the flue discharge.
Note: * If these horizontal distances cannot be achieved, AS/NZS 5601.1 states an equivalent horizontal
distance measured diagonally from the nearest discharge point of the flue terminal to the opening may be
deemed to comply. Check with the local regulator.
SAFE TRAY
Where damage to property can occur in the event of the water heater leaking, the water heater must be
installed in a safe tray. Construction, installation and draining of a safe tray must comply with AS/NZS 3500.4
and all local codes and regulatory authority requirements.
