INSTALLATION – WATER HEATER
This water heater must be installed vertically upright with
the water, gas and power connections on the underside,
pointing toward the ground. The back of the water heater
can be either against a wall or supported by a frame. The
water heater must be secured to the wall or frame using
either the screws provided or other mounting screws
suitable for the application, two each at the top and bottom
of the unit (refer to page
Alternatively the water heater can be recessed into a wall
(refer to "Recess Installation"
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 is not required. The water heater must not be installed indoors or in a confined space.
The water heater must be located to ensure that the location of the flue terminal complies with the
requirements of AS 5601, AS/NZS 5601.1 or NZS 5261, 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 300 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.
SAFE TRAY
Where damage to property can occur in the event of the water heater leaking, the water heater must be
installed over 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.
PIPE COVER
The pipe work to the water heater can be housed within a pipe cover. A pipe cover kit (AU - Part 299848,
NZ - Part 316381) is available for such an installation. Refer to the installation instructions which accompany
the pipe cover kit.
