INSTALLATION
SAFE TRAY
Where damage to property can occur in the event of the water heater leaking, the water heater must be installed in
a safe tray. Construction, installation and draining of a safe tray must comply with AS/NZS 3500.4 and all local
codes and regulatory authority requirements. AS/NZS 3500.4 also has particular requirements when a safe tray
must be installed.
FIRE RESISTANT MATERIALS
Fire resistant materials should comply with the requirements of AS 5601 Appendix C. If in doubt, seek advice from
your material supplier or your local regulator.
INDOOR INSTALLATION
The correct draft diverter must be fixed to the top of the water heater (Refer
to "Hood Conversion" on page 15) and connected to a properly constructed
flue, to discharge the 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 and to enable the water heater
top panel and draft diverter to be removed for servicing. 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.
NOTE: Reduction of the flue diameter or alteration to the draft diverter may
void the water heater warranty.
The water heater is to be installed at ground or floor level and must stand
vertically upright. There are also special requirements in AS 5601 for water
heaters installed in a garage, an enclosed space and other locations.
Remember all local authorities have regulations about putting water heaters
into roof spaces.

COMBUSTION / VENTILATION AIR
Indoor model water heaters must be installed in a protective enclosure or properly constructed plant room with
adequate ventilation in accordance with AS 5601.

level.
