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 anode
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 level on a concrete or brick plinth
or other fireproof base as approved by the local authority. The water heater
must also stand vertically upright with the back of the water heater
against or
within 25 mm of an external wall
. Failure to observe this precaution can
cause problems in high wind areas. A secondary flue is not required.
It is a requirement of AS 5601 and AS/NZS 5601.1 to secure the water heater
to the wall. The top of the unit is to be secured to the wall using the wall bracket
and masonry anchor provided, or other suitable fastener. Refer to
on page 25
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.
