INSTALLATION
Note: Australian Standard AS 3498 and New Zealand Building Code
Clause G12 requires that a water heater provides the means to inhibit the growth
of Legionella bacteria in potable water. This water heater can satisfy these
AS 3498 and Clause G12 requirements provided it is operating and the
thermostat setting is 60°C or higher, including when it is used as an in-series
booster water heater for a solar water heater.
WATER HEATER LOCATION
The water heater 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 outlet. The flue terminal must be clear
of obstructions and shrubbery.
Clearance
must
be
allowed
for
servicing of the water heater. The water
heater must be accessible without the
use of a ladder or scaffold. Make sure
the temperature pressure relief valve
lever is accessible and the access
cover, top panel and burner can be
removed for service.
If possible leave headroom of one water
heater height so the anodes can be
inspected or replaced. Remember you
may have to remove the entire water
heater later for servicing.
The water heater is to be installed at ground or floor level on a stable fireproof
base as acceptable to local authorities. The water heater must also stand
vertically upright with the back of the water heater against or within 25 mm of
an external wall or alternatively against a fireproof screen extending at least
500 mm above, below and either side the flue terminal. Failure to observe this
precaution can cause problems in high wind areas.
A secondary flue is not required.
It is recommended to secure the water heater to the wall. The top of the unit is
to be secured to the wall or screen with the wall brackets provided using
"Wall
fasteners suitable for the wall or screen type and application. Refer to
Brackets"
on page 30.
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.
