INSTALLATION
22
The water heater must be located to ensure that the location of the flue terminal
complies with the requirements of AS 5601 or AS/NZS 5601.1, as applicable
under local regulations. As a guide the following requirements are extracted from
the Gas Installations Standard. The distances are measured along the wall
behind the water heater.

At least 300 mm between the top of
the flue terminal and the eaves.

At least 500 mm between the flue
terminal and the edge of any
opening into the building, such as an
openable
door or window,
measured horizontally* and
vertically.

At least 500 mm between the flue
terminal and a return wall or external
corner, measured horizontally*.

At least 500 mm clear of any
combustibles.
Note: * If these horizontal distances cannot be achieved, AS/NZS 5601.1 states
an equivalent horizontal distance measured diagonally from the nearest
discharge point of the flue terminal to the opening may be deemed to comply.
Check with the local regulator.
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.
MAINS WATER SUPPLY
Where the mains water supply pressure exceeds that shown in the table below,
an approved pressure limiting valve is required and should be fitted as shown in
the installation diagram
(refer to diagram on page 29 ) .
Model 135
Relief valve setting 1400 kPa
Expansion control valve setting * 1200 kPa
Max. mains supply pressure
With expansion control valve 960 kPa
Without expansion control valve 1120 kPa
* Expansion control valve not supplied with the water heater.
