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®continuous flow gas water heater model you have chosen is for outdoor installation only. This
model has an extended manufacturer’s warranty (refer to the Rheem warranty on page 71).
The water heater has a maximum preset outlet temperature setting of:
•884 series 75°C
•886 series 50°C
Notes:
•The 886 series water heater is marked “THIS APPLIANCE DELIVERS WATER NOT EXCEEDING 50°C
IN ACCORDANCE WITH AS 3498” on the front panel. This model;
must not be installed as an in-series gas booster to a solar water heater, as water temperature
greater than 50°C can be delivered from the water heater contravening its compliance to AS 3498.
must not be installed with a Water Star water heater as water
temperature greater than 50°C can be delivered from the system.
•The 884 series water heater may be installed as an in-series gas
booster to a solar water heater. For information relating to the function
and operation of the solar water heater, refer to the Owner’s Guide
and Installation Instructions supplied with the solar water heater.
•When installed as an in-series gas booster to a solar water heater, the
884 series water heater:
can deliver water at temperatures up to 75°C for a Premier Loline
and Loline pumped system and a Hiline thermosiphon system and
possibly higher temperatures from a Premier Hiline thermosiphon
system.
during periods of low solar energy gain, will boost the water
temperature automatically to its preset outlet temperature setting.
WATER HEATER OPERATION
The water heater operates automatically, heating water as it passes through the water heater. When a hot
tap is opened, the gas burners ignite to provide immediate heating of the water. The heat produced by the
burner is transferred to the water through the heat exchanger. The water is heated to a constant temperature
by the automatic adjustment of the gas supply to the burner to suit the water flow rate (refer to “Temperature
Control” on pages 11 to 30). The gas burners extinguish when the hot tap is closed.
Automatic safety controls are fitted to the water heater to provide safe and efficient operation.
GAS BOOSTING FOR A SOLAR WATER HEATER
Water stored in the solar storage tank passes through the in-series gas booster when a hot tap is opened.
The in-series gas booster is for heating water at times of low solar energy gain, such as during cloudy or
rainy weather, or during colder months.
Solar heated water can reach temperatures up to 75°C for a Premier Loline and Loline pumped system and
a Hiline thermosiphon system and possibly higher for a Premier Hiline thermosiphon system. The in-series
gas booster operates automatically. When the solar heated water temperature is 58°C or higher, the flow
passes through the in-series gas booster without boosting. When the solar heated water temperature is
below 58°C, the in-series gas booster heats the water to its preset outlet temperature setting.

MAINS PRESSURE
The water heater is designed for direct connection to the mains water supply. If the mains supply pressure in
your area exceeds that shown on page 37, a pressure limiting valve must be fitted. The supply pressure
should be greater than 140 kPa for the rated flow and performance to be achieved.
HOW HOT SHOULD THE WATER BE?
The water heater may be installed with one or more user adjustable temperature controllers, which allow you
to choose the most suitable temperature for your hot water needs (refer to “Temperature Control” on
page 11).
If a controller is not installed, the water heater heats the water to the preset outlet temperature setting. The
factory preset outlet temperature setting is:
•884 series 60°C – AU 55°C – NZ
•886 series 50°C
Note: The preset outlet temperature setting of this water heater cannot be adjusted by the householder. The
setting can only be adjusted by the installer, Rheem Service or their nearest Accredited Service
Agent / Centre.
Australia New Zealand
Note: Australian Standard AS 3498 requires that a water heater provides the means to inhibit the growth of
Legionella bacteria in potable water. When this water heater is used as an in-series gas booster for a solar
water heater, it can satisfy this AS 3498 requirement provided it is energised, the booster preset outlet
temperature setting is 70°C or higher and a remote temperature controller is not used.
Warning: Temperature controllers must not be fitted to this water heater (884 series) if it is installed as
an in-series gas booster with a solar water heater or if a Water Star water heater is installed, because water
at a temperature much higher than the controller setting can be delivered. If a solar or Water Star water
heater is installed to an existing water heater installation, then all controllers must be disconnected and
removed.
If this water heater is installed as part of a solar water heater system, the system can deliver water at
temperatures from 58°C up to 75°C and possibly higher depending upon the model of solar water heater
installed.

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 be required by regulations that an approved temperature limiting device be fitted
into the hot water piping to the bathroom and ensuite when an 884 series water heater is installed. This will
keep the water temperature below 50°C – AU or 55°C – NZ at the bathroom and ensuite. The risk of scald
injury will be reduced and if no controllers are installed and the preset outlet temperature setting has not
been adjusted below 55°C or if a Kitchen controller is installed, still allow hotter water to the kitchen and
laundry.
An 886 series water heater will not deliver temperatures exceeding 50°C, in accordance with AS 3498. There
is no requirement in AS/NZS 3500.4 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.
EZ-LINK SYSTEM DUAL INSTALLATION
Two continuous flow 884 series gas water heaters installed in an Ez-LinkTM system dual installation
arrangement, when they are part of a circulated hot water flow and return system:
•AU - can only have a Kitchen controller installed, which MUST NOT be below 60°C to meet the
requirements of the Plumbing Standard.
•NZ – can have a Kitchen controller and / or Bathroom controller(s) installed and must also have an
approved UV sterilisation or chlorine disinfection system installed. This is required as the maximum
temperature controller settings are less than 60°C, and the requirements of the Plumbing Standard must
be met.
Warning: The controller must be left on during periods the circulator may operate.
PRECAUTIONS
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.
The water heater must be maintained in accordance with the Owner’s Guide and Installation Instructions.
Refer to “General Maintenance” on page 7, “Minor Six Month Maintenance” on page 7 and “Major Five Year
Service” on page 8.
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 your plumber or specifier about your needs
and building back up redundancy into your hot water supply system.

TEMPERATURE CONTROL
CONTROLLERS
The 884 and 886 series can be installed with Rheem Deluxe controllers to enable the user to control the
temperature of the delivered water from the outlet of the water heater. Rheem standard controllers will not
operate with this water heater and should not be connected.
Deluxe Controllers
There are three types of Deluxe controller. They are the Kitchen Deluxe controller (Rheem AU - Part 299861,
NZ - Part A299861), Bathroom1 Deluxe controller (Rheem AU - Part 299862, NZ - Part A299862) and the
Bathroom2 Deluxe controller (Rheem AU - Part 299863, NZ - Part A299863).
The Deluxe controllers are identified by a ‘K’ (Kitchen Deluxe controller), ‘B1’ (Bathroom1 Deluxe controller)
or ‘B2’ (Bathroom2 Deluxe controller), located under the front panel, to the bottom left hand corner adjacent
to the BATH FILL VOLUME label.
The Deluxe controllers offer additional functions to temperature control. These are:
•An assistance call function, which provides a voice prompt when pressed and will sound on all
controllers. This is useful should a family member require assistance when in the bathroom.
•A Bath Fill mode, which is designed to allow the water heater to deliver a selected volume of water at a
selected temperature. Bath filling takes place when the hot tap is opened. When the set volume has
been delivered, the water flow from the water heater ceases. Refer to “Bath Fill Mode” on page 22.
Note: The bath level should be monitored periodically while this function is in use to avoid the possibility
of the bath overflowing. The Bath Fill mode should also be used with caution until you are familiar with
its operation.
Warning: Baths should not be left unattended whenever young children are present.
Warning: Temperature controllers must not be fitted to this water heater (884 series) if it is installed as
an in-series gas booster with a solar water heater or if a Water Star water heater is installed, because water
at a temperature much higher than the controller setting can be delivered. If a solar or Water Star water
heater is installed to an existing water heater installation, then all controllers must be disconnected and
removed.
Notes:
•One, two or three controllers can be installed. Only one of each type of controller can be connected to
the water heater. Therefore, a maximum of three controllers only can be connected to each water
heater.
•A Bathroom2 Deluxe controller can only be installed if a Bathroom1 Deluxe controller is installed.
•Other manufacturers’ controllers are not suitable to and cannot be installed with this water heater.

Adjusting the Volume of the Voice Prompt and Operating Tone
The volume of the voice prompt and the operating tone can be adjusted to a level comfortable for you. The
volume of the voice prompt and the operating tone can be adjusted independently of each other. The volume
levels on a Deluxe controller are adjusted independently of another Deluxe controller.
The voice prompt and / or operating tone can also be turned off on an individual or all Deluxe controllers so
they do not sound at all.
The factory default volume setting of both the voice prompt and operating tone is medium [med]. If there is
an interruption to the water heater power supply, the volume of both the voice prompt and operating tone
returns to the default setting.
When adjusting the volume levels, the operating tone volume level is indicated by a chime, followed by the
voice prompt volume level which is indicated by two beeps. If during the volume setting procedure only the
chime is audible, this indicates the voice prompt is off. If during the volume setting procedure only the two
beeps is audible, this indicates the operating tone is off.
To adjust or turn off the volume for the voice prompt and operating tone:
•Turn off all Deluxe controllers.
•Press and hold the up (i) button, then within four (4) seconds press the ON / OFF button.
Each press of the ON / OFF button will change the voice prompt and operating tone in the following
sequence:
operating tone [MAX], voice prompt [OFF]
operating tone [MIN], voice prompt [MIN]
operating tone [MIN], voice prompt [OFF]
operating tone [OFF], voice prompt [OFF]
operating tone [MAX], voice prompt [MAX]
operating tone [MED], voice prompt [OFF]
operating tone [MED], voice prompt [MED]
This order then repeats.
Note: If the ON / OFF button is not pressed within four (4) seconds of the up (i) button being pressed,
“CL” will start flashing on the temperature display panel. If this occurs, release the up (i) button and
recommence the procedure.
ASSISTANCE CALL FUNCTION
A Deluxe controller has an assistance call button. Should assistance be required, such as when in the
bathroom, a voice prompt will sound on all Deluxe controllers to notify others that assistance is required.
The Deluxe controller does not have to be on for the assistance call function to be activated and the function
can be activated during any operation.
To Call for Assistance
To operate the assistance call function:
1. Press the green assistance call button.
The voice prompt will sound on all Deluxe controllers,
“assistance required, assistance required”
The red light in the assistance call button will glow on all
Deluxe controllers for the duration of the voice prompt.

The installation of a Bathroom Deluxe controller(s) only (i.e. no Kitchen Deluxe controller) limits the
temperature setting of the water heater to a maximum of:
•884 series 50°C
•886 series 50°C
regardless of the preset outlet temperature setting of the water heater.
The installation of a Kitchen Deluxe controller will allow a maximum temperature setting of:
•884 series 60°C – AU 55°C – NZ
•886 series 50°C
regardless of the preset outlet temperature setting of the water heater.
If a Deluxe controller(s) is not installed, the water heater defaults to the preset outlet temperature setting.
This may be up to:
•884 series 75°C
•886 series 50°C
Refer to “How Hot Should The Water Be?” on page 5.
On a building fitted with a temperature limiting device such as a tempering valve and where an 884 series
water heater is installed without a separate untempered hot water line to the kitchen, laundry or other non-
ablution area, although the Kitchen Deluxe controller will be able to display temperatures above 50°C and
the water leaving the water heater will be at the set temperature, the maximum water temperature which can
be delivered to the hot water outlets in these locations is determined by the temperature setting of the
temperature limiting device. This is usually 50°C.
On a building fitted with a temperature limiting device set to 50°C, enable the delivery of water temperatures
above 50°C to the kitchen, laundry or other non-ablution area, separate untempered pipe work must be
installed from the water heater to the hot water outlets in these locations.
