ABOUT YOUR WATER HEATER
MODEL TYPE
Congratulations for choosing a Rheem
®
water heater. The model you have
chosen is suitable for outdoor installation only. The model is either a 311 series
Rheemglas
®
, 314 series RheemPlus™ or 811 series Optima™ water heater.
Optima models have an extended warranty (refer to the warranty on page 32).
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 5.
A RheemPlus water heater is temperature
limited to deliver water not exceeding
50°C.
To meet the requirements of the National
Plumbing Standard the temperature of the
stored water must not be below 60°C.
HOTTER WATER INCREASES THE RISK
OF SCALD INJURY
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 a Rheemglas or Optima 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.
A RheemPlus water heater will not deliver temperatures exceeding 50°C, in
accordance with AS 3498. There is no statutory requirement to fit a
temperature limiting device if this water heater is installed in other than an early
childhood centre, school, nursing home or a facility for young, aged, sick or
disabled people.

TEMPERATURE ADJUSTMENT
The temperature adjusting dial is on the
gas valve, located behind the access
cover on the lower front of the water
heater. A setting of ‘6’ will normally
maintain the water temperature at about
60°C. Each number represents a
temperature difference of approximately
6°C.
To increase the water temperature to
65°C, turn the gas control knob
anticlockwise to a setting of ‘7’. Refer to
“Hotter Water Increases the Risk of
Scald Injury” on page 4.
A RheemPlus water heater is
temperature limited to 50°C at the hot
water outlet. Increasing the thermostat
setting will not increase the outlet
temperature but will provide more hot
water capacity.
WARNING
This water heater is not intended to be operated, adjusted or tampered with by
young children or infirm persons. Young children should be supervised to
ensure they do not interfere with the water heater.
SAFETY
This water heater is supplied with a thermostat, an over-temperature cut-out,
and a combination temperature pressure relief valve. In addition, a RheemPlus
water heater has a temperature limiting valve. These devices must not be
tampered with or removed. The water heater must not be operated unless each
of these devices is fitted and is in working order.
The warranty can become void if relief valves or other safety devices are
tampered with or if the installation is not in accordance with these
instructions.
ABOUT YOUR WATER HEATER

• Do not store flammable or
combustible materials near the
water heater. Flammable liquids
(such as petrol), newspapers and
similar articles must be kept well
away from the water heater and the
flue terminal.
• Do not use aerosols, stain
removers and household
chemicals near the water heater
whilst it is working. Gases from
some aerosol sprays, stain
removers and household chemicals
become corrosive when drawn into a
flame.
• Do not store swimming pool
chemicals, household cleaners,
etc., near the water heater.
• Do not place anything on top of the water heater or in contact with the flue
terminal. Ensure the flue terminal is not obstructed in any way at any time.
• Do not use Propane / Butane gas mixtures in a Propane model. A Propane
model is designed to operate on Propane only. The use of
Propane / Butane mixture, such as automotive LPG fuel, in a Propane
model is unsafe and can cause damage to the water heater.
TO TURN OFF THE WATER HEATER
If it is necessary to turn off the water heater:
• Shut down the gas control (refer to “Close Down Procedure” on page 29).
• Close the gas isolation valve at the inlet to the gas control.
• Close the cold water isolation valve at the inlet to the water heater.
TO TURN ON THE WATER HEATER
• Open the cold water isolation valve fully at the inlet to the water heater.
• Open the gas isolation valve fully at the inlet to the gas control.
• Light the water heater (refer to “Lighting the Water Heater” on page 26).

HOW DO I KNOW IF THE WATER HEATER IS INSTALLED CORRECTLY?
Installation requirements are shown on page 20. The water heater must be
installed by an authorised person and the installation must comply with National
Standards AS/NZS 3500.4, AS 5601 and all local codes and regulatory
authority requirements. In New Zealand, the installation must conform with the
Code of Practice for installation of Gas Appliances NZS 5261 and the New
Zealand Building Code.
DOES THE WATER QUALITY AFFECT THE WATER HEATER?
The water heater is suitable for most public water supplies, however some
water qualities may have detrimental effects on the cylinder and fittings. If you
are in a known harsh water area you must read page 30. If you are not sure,
have your water quality checked against the conditions described on page 30.
HOW LONG WILL THE WATER HEATER LAST?
There are a number of factors that will affect the length of service the water
heater will provide. These include the water quality, the water pressure,
temperature (inlet and outlet) and the water usage pattern. However, your
water heater is supported by a comprehensive warranty (refer to page 32).
ANODE PROTECTION
The anode(s) installed in your water heater will slowly dissipate whilst
protecting the cylinder. The life of the water heater cylinder may be extended
by arranging for an authorised person to inspect the anode(s) and replace if
required.
The suggested time after installation when the anode(s) should be inspected is:
Rheemglas 8 years
RheemPlus 8 years
Optima 10 years
For softened water supplies or in areas of poor water quality, it is
recommended the anode(s) be inspected 3 years earlier than shown (refer to
“Water Supplies” on page 30).

HOW YOUR WATER HEATER WORKS
Water is stored in a vitreous enamel lined 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 of the cylinder and through the wall of
a flue pipe which passes through the centre of the cylinder. A flue baffle in this
flue ensures the efficiency of the water heater is correct. 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.
MAINS PRESSURE
The water heater is designed to operate at
mains pressure by connecting directly to
the mains water supply. If the mains supply
pressure in your area exceeds that shown
on page 15, a pressure limiting valve must
be fitted. The supply pressure should be
greater than 350 kPa for true mains
pressure operation to be achieved.
PIEZO IGNITION
The “Piezo” push button igniter makes
lighting the pilot flame of your water heater
very easy. Simply follow the instructions on
the label attached to the back of the access
door. There is no need for matches to light
the water heater.
PILOT IGNITER
A permanent pilot flame burns to ignite the
main burner automatically. Heat from the
pilot is absorbed by the water.
GOING ON HOLIDAYS
If you are going on holiday for more than a
few days the thermostat can be set to the
“·” (pilot) position to conserve energy
(refer to point 1 of “Close Down Procedure”
on page 29). If it is necessary to turn off the
water heater, refer to “To Turn Off The
Water Heater” on page 6.

REGULAR CARE
TEMPERATURE PRESSURE RELIEF VAL VE
This valve is near the top of the water
heater and is essential for its safe
operation. It is possible for the valve to
release a little water through the drain
line during each heating period. This
occurs as the water is heated and
expands by approximately 1/50 of its
volume.
Continuous leakage of water from the
valve and its drain line may indicate a
problem with the water heater (refer to
“Temperature Pressure Relief Valve
Running” on page 12).
WARNING: Never block the outlet of
this valve or its drain line for any
reason.
Operate the easing lever on the
temperature pressure relief valve once
every six months. It is very important
you raise and lower the lever gently.
DANGER – Failure to do this 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 should be checked by
the Rheem Service Department or their
Accredited Service Agent.
The temperature pressure relief valve should be checked for performance or
replaced at intervals not exceeding 5 years, or more frequently in areas where
there is a high incidence of water deposits (refer to “Water Supplies” on
page 30).

TEMPERATURE LIMITING VALVE
A RheemPlus water heater is fitted with a temperature limiting valve at the hot
water outlet. The valve is set to deliver water not exceeding 50°C.
The valve should be checked for performance every twelve months. This can
be performed by measuring the water temperature from a hot tap with a
thermometer. If the water is being delivered at a temperature exceeding 50°C,
phone your nearest Rheem Service Department or Accredited Service Agent to
arrange for an inspection.
The valve should be replaced at intervals not exceeding 5 years, or more
frequently in areas where there is a high incidence of water deposits (refer to
“Water Supplies” on page 30). Failure to do this may result in water at a
temperature up to 70°C being delivered at the hot tap, increasing the risk of
scald injury.
EXPANSION CONTROL VALVE
In many areas, including South Australia, Western Australia and scaling water
areas, an expansion control valve is fitted to the cold water line to the water
heater. Water will flow from its drain line during the heating period.
Operate the easing lever on the expansion control valve once every six
months. It is very important you raise and lower the lever gently. The
expansion control valve should be checked for performance or replaced at
intervals not exceeding 5 years, or more frequently in areas where there is a
high incidence of water deposits.
SERVICING
For safe and efficient operation, the water heater should be serviced annually
by your nearest Rheem Service Department or their Accredited Service Agent.
Only genuine replacement parts should be used on this water heater.
Warning: Servicing of a gas water heater should only be carried out by
authorised personnel.
