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 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"
"Maximum Height To Collectors"
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.
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 collectors 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 top of the solar storage tank is to be secured to the wall or screen with
the wall brackets provided using fasteners suitable for the wall or screen
type and application. Refer to
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, and apply to the 874820 and 874860 in-series gas boosters.
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 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.
