reached, depending upon the thermostat setting.
Refer to “How Hot Should The Water Be?” on page 12 and “Temperature
Adjustment” on page 13.
• The lever on the temperature pressure relief valve and expansion control
valve (if fitted) requires to be operated every six (6) months to clear any
deposits and to ensure the valve and its drain line are not blocked.
Refer to “Relief Valves” on page 9 and “Minor Maintenance Every Six Months”
on page 16.
• For continued safety of this water heater it must be installed, operated and
maintained in accordance with the Owner’s Guide and Installation
Instructions.
• Servicing of a water heater must only be carried out by qualified personnel.
Phone Rheem Service or their nearest Accredited Service Agent.
• Only a person qualified to install or service a water heater can drain the water
heater, if this is required.
RELIEF VALVES
Temperature Pressure Relief Valve
This water heater incorporates a temperature
pressure relief valve located near the top of the
water heater. This valve is essential for the
water heater’s safe operation.
It is possible for the valve to discharge a
quantity of water through the drain line during
each heating period. This quantity should be
equal to approximately 1/50 of the hot water
used, as water expands by this volume when
heated.
Expansion Control Valve
In many areas, including South Australia and
scaling water areas, it is mandatory an
expansion control valve is fitted to the cold
water line to the water heater.
The expansion control valve will discharge the quantity of water from its drain
line during the heating period instead of the temperature pressure relief valve as
it has a lower pressure rating.

Valve Operation
Continuous leakage of water from either valve and its drain line may indicate a
problem with the water heater. Refer to “Temperature Pressure Relief Valve or
Expansion Control Valve Running” on page 24.
Warning: Never block the outlet of either valve or their drain lines for any
reason. A relief valve drain must be left open to atmosphere, and be installed in
a continuously downward direction.
In locations where water pipes are prone to freezing, the relief valve drain line
must be insulated and not exceed 300 mm in length before discharging into a
tundish through an air gap.
Operate the easing lever on the temperature
pressure relief valve and expansion control
valve once every six (6) months to clear any
deposits and ensure the valve and its drain line
are not blocked. It is very important the lever
is raised and lowered gently. Refer to “Minor
Maintenance Every Six Months” on page 16.
Warning: Water discharged from the
temperature pressure relief valve drain line will
be hot. Exercise care to avoid any splashing of
water by standing clear of the drain line’s point
of discharge when operating either valve’s
flows from the
drain line –

Warning: Failure to operate the easing lever on the relief valve once every
six (6) months may result in the water heater cylinder failing.
If water does not flow freely from the drain line when the lever is lifted, then the
water heater must be checked. Phone Rheem Service or their nearest Accredited
Service Agent to arrange for an inspection.
The temperature pressure relief valve should be replaced at intervals not
exceeding six (6) years and the expansion control valve should be checked for
performance or replaced at intervals not exceeding six (6) years. The checking
of the valves performance or replacement should occur more frequently in areas
where there is a high incidence of water deposits. Refer to “Water Supplies” on

SAFETY, WARNINGS, INSTALLATION NOTES
INSTALLATION NOTES
This water heater must be installed:
• by a qualified person,
• in accordance with the installation instructions,
• in compliance with the Plumbing Standard AS/NZS 3500.4,
This water heater is suitable for outdoor installation only.
This water heater is intended to be permanently connected to the water
mains and not connected by a hose-set. A braided flexible hose or semiflexible connector may be used for connection to the water heater, where
permitted by AS/NZS 3500.4.
• in compliance with the Gas Installations Standard AS/NZS 5601.1, and
• in compliance with all local codes and regulatory authority requirements.
Installation and commissioning requirements and details for the installing
plumber are contained on pages 26 to 47.
Mains pressure water supply
The water heater is designed to operate at mains pressure by connecting directly
to the mains water supply.
The water heater is supplied with a temperature pressure relief valve with a
pressure rating of 1400 kPa. If an expansion control valve has been installed on
the cold water line to the water heater, this should have a pressure rating of
1200 kPa.
The maximum mains water supply pressure for the water heater is 1120 kPa if
an expansion control valve is not installed, or 960 kPa if an expansion control
valve is installed. If the mains supply pressure in your area exceeds these values,
a pressure limiting valve must be installed.
The supply pressure should be greater than 350 kPa for true mains pressure
operation to be achieved.
Securing of the water heater
It is recommended the top of the water heater be secured to the wall or screen
with the wall brackets provided using fasteners suitable for the wall or screen

WATER HEATER APPLICATION
This water heater is designed for use in a single family domestic dwelling for the
purpose of heating potable water. Its use in an application other than this may
shorten its life.
MODEL TYPE
The Rheem® water heater model you have
chosen is suitable for outdoor installation only. It
is a five star high efficiency, quick recovery
Rheem 8A0340 model stainless steel water
heater.
Water is stored in a stainless steel cylinder and
heated by a gas burner located under the
cylinder. The heat produced by the burner is
transferred to the water through the base, top
and side walls of the storage cylinder with flue
baffle rings capturing heat to improve efficiency.
The gas supply to the burner is controlled by the
thermostat so the water is heated to a constant
temperature.
Automatic safety controls are fitted to the water heater to provide safe and
efficient operation.
HOW HOT SHOULD THE WATER BE?
The water heater features a user adjustable
thermostat, which allows you to personally
choose the most suitable temperature for your
hot water needs. Refer to “Temperature
Adjustment” on page 13.
To meet the requirements of the National
Plumbing Standard the temperature of the
stored water must not be below 60°C.
Note: AS 3498 requires that a water heater
provides the means to inhibit the growth of
Legionella bacteria in potable water. This water
heater can satisfy this AS 3498 requirement
provided it is operating and the thermostat
setting is 60°C or higher, including when it is
used as an in-series booster water heater for a
solar water heater.

HOTTER WATER INCREASES THE RISK OF SCALD INJURY
temperature dial position indicator
This water heater can deliver water at temperatures which can cause scalding.
Check the water temperature before use, such as when entering a shower or
filling a bath or basin, to ensure it is suitable for the application and will not cause
scald injury.
We recommend and it may also be required by regulations that an approved
temperature limiting device be fitted into the hot water pipe work to the bathroom
and ensuite when this water heater is installed. This will keep the water
temperature below 50°C at the bathroom and ensuite. The risk of scald injury will
be reduced and still allow hotter water to the kitchen and laundry.
TEMPERATURE ADJUSTMENT
Gas Control Temperature Dial
This water heater features a user adjustable thermostat (gas control) which
controls the stored water temperature. This is located behind the front access
cover on the lower front of the water heater. The temperature dial on the gas
control is used to control the water temperature inside of the storage cylinder.
The thermostat automatically controls the gas supply to the burner so a constant
water temperature is maintained within the storage cylinder. The thermostat is
fully automatic and the burner only operates when the water in the storage
cylinder requires heating. There is no need to switch the water heater off when it
is not in use, except perhaps when you are going away for an extended period.
The thermostat is adjustable up to
approximately 75°C. The temperature dial is
marked with numerals and each number
represents a temperature difference of
approximately 10°C. When aligned with the
temperature dial position indicator on the gas
control body, a setting of mid way between ‘3’
and ‘4’ will normally maintain the water
temperature at about 60°C.
To increase the water temperature to 75°C,
turn the temperature dial anticlockwise to a
setting of ‘5’. Refer to “Hotter Water Increases
the Risk of Scald Injury” on page 13.
