SAFETY, WARNINGS, INSTALLATION NOTES
It is important you read the following safety and warnings information.
SAFETY AND WARNINGS
This water heater is only intended to be operated by persons who have the
experience or the knowledge and the capabilities to do so.
This water heater is not intended to be operated by persons with reduced
physical, sensory or mental capabilities i.e. the infirm, or by children. Children
should be supervised to ensure they do not interfere with the water heater.
If the power supply cord, plug or electrical conduit to the water heater is
damaged, it must be replaced by a qualified person in order to avoid a hazard.
The power supply cord and plug must be replaced with a genuine
replacement part available from Rheem. Phone Rheem Service or their
nearest Accredited Service Agent to arrange for an inspection.
Take care not to touch the power plug, on a water heater fitted with a power
supply cord and plug, with wet hands.
This water heater uses 220 V – 240 V a.c. power for the electrically operated
components. The removal of the front cover will expose 220 V – 240 V a.c.
wiring. It must only be removed by a qualified person.
This water heater is supplied with a thermostat, an over-temperature cut-out
and a combination temperature pressure relief 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 Rheem warranty may not cover faults if relief valves or other safety
devices are tampered with or if the installation is not in accordance with
these instructions.
DANGER: The operation of the over-temperature cut-out on a thermostat
indicates a possibly dangerous situation. If the over-temperature cut-out
operates, it must not be reset and the water heater must be serviced by a
qualified person.
The water heater will operate until a water temperature of 60°C to 70°C for
025 models or 60°C to 75°C for 045 and 050 models is reached, depending
upon the thermostat setting.
Refer to “How Hot Should The Water Be?” on page 12 and “Temperature
Adjustment” on page 13.

SAFETY, WARNINGS, INSTALLATION NOTES
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 17.
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.
Do not modify this water heater.
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, Western 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 23.

SAFETY, WARNINGS, INSTALLATION NOTES
lift until water
flows from the
drain line –
lower gently
drain
line
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 17.
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
easing lever.
DANGER: Failure to operate the easing lever on the relief valve once every
six (6) months may result in the water heater cylinder failing, or under certain
circumstances, exploding.
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 five (5) years and the expansion control valve should be checked for
performance or replaced at intervals not exceeding five (5) 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
page 18.
INSTALLATION NOTES
This water heater must be installed:

ABOUT YOUR WATER HEATER
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 Rheemglas® 111 or 191 series water
heater you have chosen has a single
heating unit and is suitable for connection to
a continuous power supply. The water
heater is suitable for either indoor or outdoor
installation, except a water heater supplied
with a power supply cord and plug is
suitable for indoor installation only.
Water is stored in a vitreous enamel lined
steel cylinder and heated by the electric
immersion heating unit. The thermostat
controls the temperature. Automatic safety
controls are fitted to the water heater to
provide safe and efficient operation.
A 191 series water heater has caps covering
brass plugs on one side of the tank. The
plugs and caps block off alternative
connection points and are not to be
HOW HOT SHOULD THE WATER BE?
The water heater features a tradesperson
adjustable thermostat, which allows you to
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.
tampered with or removed.

ABOUT YOUR WATER HEATER
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 111 or 191 series 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.
THERMOSTAT
The thermostat automatically controls the electricity supply to the heating unit so
a constant temperature is maintained. The thermostat and its protective over
temperature cut out is mounted inside the front cover of the water heater. There
is no need to switch the water heater off when it is not in use, except when you
are on an extended holiday. The thermostat is fully automatic and power is only
used when heating is required.
TEMPERATURE ADJUSTMENT
A Rheemglas 111 series 025 model and 191 series 025 to 050 model water
heater feature a tradesperson adjustable thermostat. This requires a licensed
electrical worker to make any temperature adjustments. The thermostat has a
maximum temperature setting of 70°C for 025 models and 75°C for 045 and
050 models. The minimum temperature setting is 60°C.
We advise you to have a licensed electrical worker adjust the thermostat to the
lowest temperature setting that meets your needs, especially if there are young
children or elderly people in your home. Refer to “Hotter Water Increases The
Risk of Scald Injury” on page 13.
13
ABOUT YOUR WATER HEATER
PRECAUTIONS
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.
The water heater must be maintained in accordance with the Owner’s Guide and
Installation Instructions. Refer to “Maintenance Requirements” on page 16 and
to “Anode Inspection and Replacement” on page 19.
If this water heater is to be used where an uninterrupted hot water supply is
necessary for your application or business you should ensure that you have
back-up redundancy within the hot water system design. This should ensure the
continuity of hot water supply in the event that this water heater were to become
inoperable for any reason. We recommend you seek advice from a plumber or
specifier about your needs and building back-up redundancy into your hot water
supply system.
TO TURN OFF THE WATER HEATER
If you plan to be away from home for only a few nights, we suggest you leave
the water heater switched on.
If it is necessary to turn off the water heater:
