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*.
At least 1500 mm between the top of the flue terminal and
the edge of any opening into the building, such as an
openable window, measured vertically.
At least 300 mm between the flue terminal and a return wall
or external corner, measured horizontally*.
At least 1500 mm between the flue terminal and any
opening into a building, in the direction of the flue
discharge.
At least 500 mm between the flue terminal and a fence, wall or other obstruction, in the direction of the
flue discharge.
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.
The water heater can be turned through 60°, either to the left or to the right, with the discharge from the flue
terminal discharging along the wall.
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
Model
270
Relief valve setting
1000 kPa
Expansion control valve setting *
850 kPa
Max. mains supply pressure
With expansion control valve
680 kPa
Without expansion control valve
800 kPa
Min. mains supply pressure
140 kPa
* Expansion control valve not supplied with the water heater.
Notes:
It is not recommended to install this water heater with a low pressure water supply.
This water heater is not suitable for connection to bore water or spring water unless a water treatment
device is fitted.
If sludge or foreign matter is present in the water supply, it is recommended a suitable filter be
incorporated in the cold water line to the water heater.
