INSTALLATION

THIS WATER HEATER IS FOR INDOOR INSTALLATION ONLY.
THIS WATER HEATER IS NOT SUITABLE FOR POOL HEATING.
Check the water heater is suitable for the gas type available
(refer to the rating label on the water heater).
Note: The 620 130 heavy duty water heater is designed for small commercial
applications requiring sanitising temperatures and has a maximum temperature
setting of 80°C. This model should not be installed in a domestic residence.
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.
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 front cover and
burner 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 length so
the anode can be inspected or replaced.
Remember you may have to remove the
entire water heater later for servicing.
The installation must comply with the requirements of AS/NZS 3500.4, AS 5601
and all local codes and regulatory authority requirements. In New Zealand, the
installation must conform with NZS 5261 Code of Practice for Installation of
Gas Burning Appliances and the New Zealand Building Code.
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.
A secondary flue must be installed with an indoor water heater to discharge
combustion products outside the building. The flue must be self supporting and
not impose a load on the water heater. Use a slip joint or similar to allow for
disconnection. There must be a vertical rise of 600 mm from the draught
diverter before changing direction. The flue design and installation must comply
with AS 5601.
