INSTALLATION – WATER HEATER
46
This water heater must be installed vertically upright with
the water, gas and power connections on the underside,
pointing toward the floor. The back of the water heater can
be either against a wall or supported by a frame.
Note: The water heater must be well secured to the wall or
frame using two fasteners each at the top and bottom of
the unit (refer to page 53 for mounting hole positions and
weight of the water heater). Use the screws provided only
if they are suitable for the wall or frame type. Otherwise
select and use alternative fasteners suitable for the
application. The fasteners must be capable of bearing the
full weight of the water heater so it may not work loose nor
impose any load on the gas and water pipe work
connected to the water heater. Refer to the fastener
manufacturer‟s information and recommendations for the
type of fastener to use for the wall or frame type and load
bearing requirements.
For a single water heater installation, refer to the typical installation diagram on page 56.
For a dual water heater installation using the Ez-Link system, refer to “Ez-Link System Dual Installation” on
page 77 and the typical installation diagram on page 81.
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.
VENTILATION
This water heater is to be installed with a Rheem coaxial flue system. The kit enables a room sealed
installation, drawing air for combustion from outside of the building.
The ventilation of a room or an enclosure such as a cupboard, where the water heater is installed must
comply with the requirements of AS 5601 or AS/NZS 5601.1, as applicable under local regulations.
SECONDARY FLUE
A secondary flue must be installed with an indoor water heater to discharge combustion products to outside
the building. The water heater MUST ONLY be installed with a certified Rheem coaxial flue system.
Where more than one water heater is installed, each water heater must be individually flued using a certified
Rheem coaxial flue system. A common flue system MUST NOT be used.
Refer to “Flueing” on page 59 for details on the flue requirements and installation details.
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 (PN 299848) is
available for such an installation. Refer to the installation instructions which accompany the pipe cover kit.
