INSTALLATION
for any reason. We recommend you provide advice to the system owner about
their needs and building back-up 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 can satisfy this
AS 3498 requirement 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 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 bracket provided using fasteners
"Wall Bracket"
suitable for the wall or screen type and application. Refer to
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.
