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 Rheem®water heater model you have
chosen is suitable for indoor installation only.
The model is an 800 series Rheemglas®water
heater.
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.
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 9.
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
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
The temperature adjusting dial is on the gas
valve, located at 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 9.
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 front of the water
heater. 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.

SAFETY
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.
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.
For continued safety of this water heater it must be installed, operated and
maintained in accordance with the Owner’s Guide and Installation
Instructions.
Do not modify this water heater.
Do not use or store flammable materials in
or near this water heater. Flammable liquids
(such as petrol), combustible materials
(such as newspapers) and similar articles
must be kept well away from the water
heater and the draught diverter.
Do not spray aerosols in the vicinity of this
water heater while it is in operation. Gases
from many aerosol sprays are flammable,
or may become corrosive when drawn into
a flame.
Do not store swimming pool chemicals, household cleaners, etc., near
the water heater.
Do not place articles on or against this water heater, or in contact with the
draught diverter. Ensure the draught diverter 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 LP gas fuel, in a Propane model is unsafe and
can cause damage to the water heater.
