WARNING: Plumber – Be Aware
Use copper pipe ONLY. Plastic pipe MUST NOT be used.
It is a requirement of a solar water heater installation that all
pipe work be in copper and not plastic, due to the effects of
high water temperatures and pressures.
This water heater must be installed and serviced by an authorised person.
Please leave this guide with the householder.

Notice to Victorian Customers from the
Victorian Plumbing Industry Commission.
This water heater must be installed by a licensed person as required by
the Victorian Building Act 1993.
Only a licensed person will give you a Compliance Certificate, showing that
the work complies with all the relevant standards. Only a licensed person will
have insurance protecting their workmanship for 6 years. Make sure you use
a licensed person to install this water heater and ask for your Compliance
Certificate.

WARNING: Plumber – Be Aware
•

•

Plastic pipe MUST NOT be used, as it will not withstand the temperature
and pressure of the water generated by the solar collectors under
stagnation conditions. The solar collectors can generate extremely high
water temperatures up to 150°C and high water pressure of 1000 kPa.
Plastic pipe cannot withstand these temperatures and pressures and
MUST NOT be used. Failure of plastic pipe can lead to the release of
high temperature water and cause severe water damage and flooding.
Refer to Warning on page 38.

•

A non return valve MUST BE installed on the cold water line to the solar
storage tank AFTER the cold water branch to a temperature limiting
device. Due to the higher water temperatures generated under certain
conditions in the solar collectors of this solar water heater, an additional
effective back-flow prevention device also should be used as an extra
safeguard. Valve manufacturer RMC recommends Dual Check Valve
model N7150, as being suitable for this application.

SOLAR MONITOR
The solar control unit on an electric boosted system may incorporate a solar
monitor. The solar monitor is located on the side of the solar control unit and
houses both a green and a red LED. A gas boosted model may have a solar
monitor located on the left hand side of the air duct.

The green LED, marked “Solar”, indicates the current operational mode of the
solar water heater and the red LED, marked “Attention”, indicates a fault mode.
The green LED will emit either a constant glow or a series of flashes, with a
2 second interval between each series.
The red LED will emit a series of flashes, with a 2 second interval between
each series, only if there is a particular fault condition with the system.

SOLAR CONTROLLER AND SOLAR MONITOR
COMMISSIONING
When the electrical supply is switched on to the solar control unit at start up:
•

If there is no solar gain, the circulator will not activate and the green LED
will emit a slow pulse.
The slow pulse indicates the circulator is not activated and the power to the
solar control unit has been on for less than 48 hours.

•

If there is solar gain, the circulator activates and the green LED will emit a
series of three (3) flashes.
The three (3) flashes indicate the circulator is operating and power to the
solar control unit has been on for less than 48 hours.

•

The circulator will operate at full speed for approximately fifteen (15)
seconds. If the red LED is emitting a rapid pulse, the circulator may operate
at full speed for up to ten (10) minutes.
After fifteen (15) seconds or after the red LED has extinguished, the solar
controller will commence to pulse the circulator to control the flow rate
through the collector circuit and achieve a constant temperature rise across
the collector(s). It is normal operation for the circulator to experience a
pulsing effect.

•

The red LED may emit a rapid pulse for a short period.
This indicates a temperature difference between the hot sensor and cold
sensor of greater than 40°C and does not represent a fault code. This is the
result of a build-up of heat and increase in water temperature in the
collector prior to the switching on of the electrical supply to the solar control
unit.
The rapid pulsing of the red LED will cease as the water circulates and the
heat is dissipated. This should be within four (4) to five (5) minutes of start
up, but may take up to ten (10) minutes.
If the red LED does continue to emit a rapid pulse for longer than ten (10)
minutes, this may indicate water is not circulating through the collectors and
solar circuit:

switch off the electrical supply at the power outlet to the solar control unit

repeat the procedure to bleed the solar collectors

switch on the electrical supply at the power outlet to the solar control unit

The red LED may emit up to six flashes in each series of flashes.
Note: During periods of high solar radiation and if the circulator activates after
having been off, such as during start up, it is possible the red LED may emit a
rapid pulse for a period of up to ten (10) minutes. This does not indicate a fault.
Refer to “Commissioning” on page 2.
If the red LED continues to emit a rapid pulse for longer than ten (10) minutes,
or emits a series of flashes, then count the number of flashes and phone your
nearest Service Department or Accredited Service Agent to arrange for an
inspection.

ABOUT YOUR WATER HEATER
MODEL TYPE
Congratulations for choosing a Rheem® water heater. Your Rheem solar
Loline™ water heater is designed for the solar collectors to be roof mounted
and the solar storage tank to be installed at ground level. The solar storage
tank is suitable for outdoor installation only and can be installed with Rheem
NPT 200 solar collectors. The system is not suitable for installation above
400 metres altitude.
The system when installed in areas subject to freeze conditions must be
installed with the solar hot and solar cold pipes fully insulated with closed cell
polymer insulation (minimum thickness 13 mm) to offer protection against
freeze damage. Freeze conditions occur below 6°C. The system has NO
WARRANTY for freeze damage when installed above 400 metres altitude or if
the solar hot and solar cold pipes are uninsulated (refer to “Warranty
Exclusions” on page 59 and to “Pipe Work and Insulation” on page 8).
HOW HOT SHOULD THE WATER BE?
The solar control unit will circulate
water through the solar collectors until
a temperature of approximately 75°C is
reached. During periods of low solar
energy gain, the water temperature can
be boosted by the thermostatically
controlled gas burner. The boosting is
controlled by both the timer unit and the
gas control thermostat.
The water heater features a user
adjustable thermostat, which allows you
to personally choose the most suitable
boosting temperature for your hot water
“Temperature
needs.
Refer
to
Adjustment” on page 5.
To meet the requirements of the
National Plumbing Standard the
temperature of the stored water must
not
be
below
60°C.
Rheem
recommends the thermostat is set at
60°C to maximise solar contribution.

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 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, behind the access cover on the
lower front of the water heater. A setting of
‘6’ will normally provide a boosted water
temperature of about 60°C. Each number
represents a temperature difference of
approximately 6°C.
To increase the boosted water temperature
to 65°C, turn the gas control knob counterclockwise to a setting of ‘7’. Refer to “Hotter
Water Increases the Risk of Scald Injury”
on page 5.
WARNING
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.
This water heater uses 240 V AC electrical power for operation of the control
systems and the electrically operated components. The removal of the side
access panel will expose 240 V wiring. It must only be removed by an
authorised or qualified person.
Care should be taken not to touch the pipe work connecting the solar storage
tank and the solar collectors. Very high temperature hot water can be
generated by the solar collectors under certain conditions and flow through the
pipe work from the solar collectors to the solar storage tank.

ABOUT YOUR WATER HEATER
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.
If the electrical conduit to the water heater is damaged, it must be replaced by
an authorised person in order to avoid a hazard. Phone your nearest Rheem
Service Department or Accredited Service Agent to arrange for an inspection.
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.
•

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.

ABOUT YOUR 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 51).

•

Close the gas isolation valve at the inlet to the gas control.

•

Switch off the electrical supply at the isolating switch to the water heater
(refer to note below).

•

Close the cold water isolation valve at the inlet to the water heater.

Note: If there is a risk of freezing conditions, the electrical supply to the solar
control unit should not be switched off unless the solar collectors are drained,
otherwise damage could result (refer to “Freeze Protection” on page 10).
TO TURN ON THE WATER HEATER
•

Open the cold water isolation valve fully at the inlet to the water heater.

•

If the solar collectors and solar hot and solar cold pipes have been drained,
it will be necessary to bleed the collector circuit (refer to “Bleeding the Solar
Collectors” on page 9).

•

If the electrical supply to the water heater has been switched off, switch on
the electrical supply at the isolating switch. The isolating switch must be
switched on for the solar control unit to operate and solar gain to be
achieved.

•

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 48).

•

Ensure the timer is programmed (refer to “Timer Operation” on page 16).

HOW DO I KNOW IF THE WATER HEATER IS INSTALLED CORRECTLY?
Installation requirements are shown on page 34. The water heater must be
installed by an authorised person and the installation must comply with National
Standards AS/NZS 3500.4, AS/NZS 3000, 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. The timer is not weatherproof and must
be installed indoors.

ABOUT YOUR WATER HEATER
PIPE WORK AND INSULATION
The solar hot and solar cold pipe work between the solar storage tank and the
solar collectors MUST BE of copper and fully insulated with closed cell polymer
insulation or similar (minimum thickness 13 mm). The insulation must be
weatherproof and UV resistant if exposed. The insulation is essential to assist
in providing freeze protection, will offer corrosion protection to a metal roof
against water runoff over the copper pipe, assist in avoiding accidental contact
with the solar pipe work and also reduce pipe heat losses.
The insulation must be fitted up to the connections on both the solar collectors
and the solar storage tank, as very high temperature water can flow from the
solar collectors to the solar storage tank under certain conditions.
Plastic pipe MUST NOT be used, as it will not withstand the temperature and
pressure of the water generated by the solar collectors under certain conditions
(refer to Warning on page 38).
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, solar collectors
and fittings. If you are in a known harsh water area you must read page 56.
If you are not sure, have your water quality checked against the conditions
described on page 56.
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 60).
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 replacing it if
required.
The suggested time after installation when the anode(s) should be inspected is
8 years.
For softened water supplies or in areas of poor water quality, it is
recommended the anode be inspected 3 years earlier than shown (refer to
“Water Supplies” on page 56).

ABOUT YOUR WATER HEATER
BLEEDING THE SOLAR COLLECTORS
It is necessary to purge air from the collector circuit:
•

When the water heater is to be turned on and the solar collectors and solar
hot and solar cold pipe work have been drained.

•

After maintenance has been conducted on the pipe work and air has
entered the system.

•

If the circulator appears not to be circulating water around the system.

Warning: Bleeding the solar collectors should be conducted in the morning,
within three hours of sunrise, when the water temperature inside the solar
collectors is lower.
To purge air from the collector circuit:
•

Ensure the water heater is full of water and all of the hot taps are turned off.

•

Using a flat blade screwdriver,
open the bleed valve (if it is
not already open) fitted
adjacent to the solar hot
water (from collector) inlet of
the solar storage tank (see
diagram).

•

The mains pressure will force
water to flow from the tank
and through the pipe work,
expelling air from the collector
circuit through the bleed
valve. This is evidenced by
spurting of water from the
drain line connected to the
bleed valve.
Warning: Exercise care to
avoid any splashing of water,
as water discharged from the
solar collectors may be of a
very high temperature.

•

Close the bleed valve when water runs freely from the drain line.

ABOUT YOUR WATER HEATER
FREEZE PROTECTION
The system when installed in areas subject to freeze conditions must be
installed with the solar hot and solar cold pipes fully insulated with closed cell
polymer insulation (minimum thickness 13 mm) to offer protection against
freeze damage. Freeze conditions occur below 6°C. The system has NO
WARRANTY for freeze damage when installed above 400 metres altitude or if
the solar hot and solar cold pipes are uninsulated (refer to “Warranty
Exclusions” on page 59 and to “Pipe Work and Insulation” on page 8).
The anti freeze control is designed to recirculate a small amount of water from
the solar storage tank through the solar pipe work during periods of low
temperatures. This is to prevent the water inside the pipe work from freezing. It
is essential that the electrical circuit to the solar control unit is continually turned
on if there is a risk of freezing. The solar warranty does not cover damage
caused by freeze conditions when the electrical circuit to the solar control unit
is turned off or interrupted.
Notes:
•

If it is necessary to switch the power off to the solar control unit and there is
a risk of freezing, then it is necessary to have your plumber drain the solar
collectors and solar flow and return pipe work.

•

The freeze protection system will be rendered inoperable if electrical power
is not available at the water heater. Damage caused by freezing due to no
power at the water heater, is not covered by warranty.

•

Pipe work between the solar collectors and solar storage tank must be
insulated.

•

The system is not covered for freeze damage above 400 metres altitude.

•

Refer to “Warranty Exclusions” on page 59.

HOW YOUR WATER HEATER WORKS
The Rheem solar Loline system has its vitreous enamel lined solar storage tank
installed at ground level, remotely from the solar collectors. As the sun heats
the water in the solar collectors the increase in temperature activates the
circulator. The circulator then moves the water from the solar collectors through
an insulated copper pipe to the solar storage tank. The circulator switches on
whenever the water leaving the solar collectors is hotter than the water in the
tank. Cooler water from the solar storage tank is circulated to the solar
collectors to be heated by the sun’s energy. This process continues while solar
energy is available and until the water in the solar storage tank reaches a
temperature of approximately 75°C. 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 28, a pressure limiting valve must be fitted. The
supply pressure should be greater than 350 kPa for true mains pressure
operation to be achieved. A minimum water supply pressure of 200 kPa is
required to enable the solar circulator and solar circuit system to operate
effectively.
GAS BOOSTING
Water stored in the solar storage tank can be
heated by a gas burner located under the
cylinder. The gas burner is for heating the
water at times of low solar energy gain, such
as during very cloudy or rainy weather, or
during the winter months. The boost water
temperature is determined by the gas control
thermostat setting.
The gas burner is also controlled via a timer
unit installed inside the house. It is
recommended the timer be set to enable
boosting between 4:00 PM and 6:30 PM. This
will allow boosting of the water temperature
before the main evening hot water usage
period, but after the main solar heating period
of the day. The timer unit has a manual
“OVERRIDE” to allow boosting outside of the
set hours (refer to “Timer Operation” on
page 16).
Note: The gas burner will only light if the temperature of the water in the solar
storage tank is below the gas control thermostat setting.

HOW YOUR WATER HEATER WORKS
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 for
boosting. 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 its lowest setting (‘1’) to conserve energy. Alternatively, the timer can be set
so the burner will not activate during the period you are away (refer to “Timer
Operation” on page 16). If it is necessary to turn off the water heater, refer to
“To Turn Off The Water Heater” on page 7. Also if the system is not used for a
period in excess of two (2) weeks it is recommended the solar collectors be
covered.

REGULAR CARE
TEMPERATURE PRESSURE RELIEF VALVE
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 23).
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.

heater

Warning: 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 of 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 56).

REGULAR CARE
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. The expansion control valve may discharge a small quantity of water
from its drain line during the heating period instead of the temperature pressure
relief valve on the water heater.
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.
COLLECTOR GLASS
Ensure the glass on your solar collectors is free of dust, salt spray or any other
matter, which may reduce the effectiveness of the solar collectors. If the
collector glass becomes dirty, hose down or if the solar collectors are
accessible, wash the collector glass with water and a soft brush when the solar
collectors are cool. Have any trees trimmed which may shade the solar
collectors.

REGULAR CARE
FLUSHING THE SOLAR COLLECTORS
It may be necessary to flush the solar collectors if there is sediment in the water
supply. This should be conducted in the morning, within three hours of sunrise,
when the water temperature inside the solar collector(s) is lower.
•

Open a hot water tap and allow the water to run for five (5) minutes prior to
flushing the solar collector(s).

•

Close the hot tap.

•

Wait a further five (5) minutes before attempting to flush the solar collectors.
This will assist in the transfer of any high temperature water in the solar
collector(s) to the solar storage tank.
Warning: Exercise care, as water discharged from the solar collectors
may be of a very high temperature.

•

To flush the solar collectors, follow the procedure “Bleeding the Solar
Collectors” on page 9, allowing the water to flow from the bleed valve drain
line for five (5) minutes before closing the bleed valve.

It is recommended to flush the solar collectors every five (5) years. This will
assist in keeping the solar collectors, solar cold pipe and solar hot pipe clear of
sediment.

TIMER OPERATION
FUNCTIONS OF THE TIMER
The timer is an accurate, electronic device which allows up to six (6) ON-OFF
periods to be set per day. It is recommended only one (1) period per day be
programmed into the timer. This will be sufficient for most installations. The
timer is not weatherproof and must be installed indoors. It is recommended the
timer be located in the kitchen or laundry or other location easily seen by the
householder.

TIMER OPERATION
The function of the timer is to enable the gas burner to automatically boost the
stored water temperature, if required, due to low solar energy gain during the
day. This will ensure the solar storage tank is full of hot water for the evening
hot water requirements.
Warning: The timer is not waterproof. Do not splash the timer with water.
BATTERY BACKUP
The timer has an inbuilt rechargeable battery. If a power failure occurs, the
rechargeable battery will maintain the memory of the timer, avoiding the loss of
any set programs.
Note: The rechargeable battery may be run down at the time of installation.
Connecting to mains power will recharge the battery.
RECOMMENDED TIMER ON/OFF SETTING
It is recommended the timer be set to enable boosting between
4:00 PM (16:00 Hours) and 6:30 PM (18:30 Hours). Note: The timer uses a
24 hour clock. This two and a half hour boosting period is sufficient to allow the
gas burner to heat up the entire contents of the solar storage tank through a
45°C temperature rise. This may be necessary during periods of very low solar
energy gain through the solar collectors, such as during constant rain or
extremely cloudy weather.
It may be necessary and is recommended to reset the timer during daylight
saving time (in the states where applicable), to enable boosting between
5:00 PM (17:00 Hours) and 7:30 PM (19:30 Hours), to maximise the solar
energy gain during this period.
RESET THE TIMER
It is recommended the timer be reset before commencing the initial
programming. This will delete any set programs.
•

Press the “R” button gently to reset the

SAVE A SERVICE CALL
Check the items below before making a service call. You will be charged for
attending to any condition or fault that is not related to manufacture or failure of
a part.
NOT ENOUGH HOT WATER (OR NO HOT WATER)
This can occur with new installations and is normally related to some
misunderstandings as to the use of the timer and gas booster.
•

Insufficient sunlight
Insufficient sunlight due to cloudy
weather during summer months or
low solar energy contribution in
winter months may mean you will
need to activate the gas boosting
more often (refer to “Manual
Boosting – Override Function” on
page 20).

•

Pilot flame alight?
Check the pilot flame is burning by
removing the access cover. Relight
the pilot flame according to the
lighting
instructions
(refer
to
“Lighting the Water Heater” on
page 48).

•

Gas burner not operating
Inspect the isolating switch (adjacent to the water heater or at the switch
board marked “HOT WATER” or “WATER HEATER”) and ensure it is turned
“ON”.
Note: Check the settings on the TIMER are sufficient to allow a full boosting
cycle (2½ hours, from 4:00 PM to 6:30 PM, is recommended).

•

Collectors shaded
If trees or other objects shade the solar collectors or if the glass is dirty, the
effectiveness of the solar collectors will be greatly reduced. Have the trees
trimmed or the solar collectors relocated if the obstruction is permanent or
clean the collector glass (refer to “Collector Glass” on page 14).

•

Collector area is too small
For most installations, the number of solar collectors recommended in
Rheem literature has been proven to provide the required solar energy to
meet the average family needs. However, in some circumstances, it may be
necessary to install an additional solar collector.

SAVE A SERVICE CALL
•

Air in collectors (No solar gain)
It is possible under certain conditions, such as when the pipe work has been
opened, that air may become trapped in the solar collectors. This will
prevent the circulator from moving water around the collector circuit. The air
will need to be purged from the solar collectors (refer to “Bleeding The Solar
Collectors” on page 9).

•

Are you using more hot water than you think?
Is one outlet (especially the shower) using more hot water than you think?
Very often it is not realised the amount of hot water used, particularly when
showering. Carefully review the family’s hot water usage. As you have
installed an energy saving appliance, energy saving should also be
practised in the home. Adjust your water usage pattern to take advantage of
maximum solar gains. Have your plumber fit a flow control valve to each
shower outlet to reduce water usage.

•

Temperature pressure relief valve running
Is the relief valve discharging too much water? (Refer to “Temperature
Pressure Relief Valve Running” on page 23).

•

Thermostat setting
Ensure the thermostat setting is appropriate. You may choose to adjust the
thermostat upwards to gain additional hot water capacity when boosting.
Warning: Hotter water increases the risk of scald injury.

•

Water heater size
Do you have the correct size water heater for your requirements? The sizing
guide in the sales literature and on the Rheem website
(www.rheem.com.au) suggests average sizes that may be needed.

WATER NOT HOT ENOUGH
You may find that due to heavy hot water usage or low solar energy gain the
water temperature may be lower than normally expected. You will need to
carefully plan your use of the gas burner to boost the water temperature on
such occasions.
A lower water temperature may also be noticed in the morning if the gas
boosting has not been used. This in particular may be experienced during
periods of low solar energy gain, or if there has been heavy hot water usage
the previous night.

SAVE A SERVICE CALL
TEMPERATURE PRESSURE RELIEF VALVE RUNNING
Normal Operation
It is normal and desirable this valve
allows a small quantity of water to
escape during the heating cycle.
However, if it discharges more than
a bucket full of water in 24 hours,
there may be another problem.

•

Continuous dribble
Try gently raising the easing lever
on the relief valve for a few
seconds (refer to “Temperature
Pressure Relief Valve” on page 13).
This may dislodge a small particle
of foreign matter and clear the fault.
Release the lever gently.

•

Steady flows for long period
(often at night)
This may indicate the mains water
pressure sometimes rises above
the designed pressure of the water
heater. Ask your installing plumber
to fit a pressure limiting valve.
Warning: Never replace the relief valve with one of a higher pressure
rating.

•

Heavy flows of hot water until the water heater is cold - then stops
until water reheats
The gas control must be turned off using the knob on top of the gas control
thermostat (refer to “Close Down Procedure” on page 51). Phone your
nearest Rheem Service Department or Accredited Service Agent to arrange
for inspection.

EXPANSION CONTROL VALVE RUNNING
If an expansion control valve is fitted in the cold water line to the water heater
(refer to page 40) it may discharge a small quantity of water instead of the
temperature pressure relief valve on the water heater. The benefit is that
energy is conserved as the discharged water is cooler.

SAVE A SERVICE CALL
TIMER APPEARS TO BE FUNCTIONING INCORRECTLY
Check the following:
•

Has the programming been set correctly? Check the programmed “ON” and
“OFF” times (refer to “Timer Operation” on page 16).

•

Has the “R” (reset) button been inadvertently pressed? Reprogram the
timer.

•

Has the timer been set to the
“RANDOM” function? Deactivate
the “RANDOM” function (refer to
“Caution - Random Function” on
page 20).

CAN’T LIGHT THE PILOT FLAME
•

Is there gas to the water heater?
Check the gas isolation valve on
the gas supply line is open.

•

Is there a normal gas supply to
the rest of the premises?
Try lighting another gas appliance
to check. If there is no gas, call the
gas supplier.

WATER HEATER APPEARS TO BE LEAKING
When the water heater is first lit, or after a large usage of hot water,
condensation may form on the burner of the water heater. This is quite normal,
especially in winter months and will dry off as the water is heated.
COLLECTOR GLASS
Warranty DOES NOT cover breakage of solar collector glass. Check your
household insurance policy covers collector glass breakage.
Warning: Collector glass must not be replaced whilst the solar collector is
on the roof.
The collector glass is not offered as a replacement part and no attempt should
be made to remove it. Should the solar collector require replacement, contact
your nearest Rheem Service Department or Accredited Service Agent.

SAVE A SERVICE CALL
HIGH GAS BILLS
With the installation of your new solar hot water system, maximum gas energy
savings can be achieved with careful planning of hot water usage. Should you
at any time, feel your gas account is too high, we suggest you check the
following points:
•

Is the relief valve running
excessively?
(Refer
to
“Temperature
Pressure
Relief
Valve Running” on page 23).

•

Is one outlet (especially the
shower) using more hot water than
you think? (Refer to “Not Enough
Hot Water” on page 21).

•

Is there a leaking hot water pipe,
dripping hot water tap, etc? Even a
small leak will waste a surprising
quantity of hot water and gas.
Replace faulty tap washers and
have your plumber rectify any
leaking pipe work.

•

Are you using the gas boosting properly? (Refer to “Timer Operation” on
page 16).

•

Consider recent changes to your hot water usage pattern and check if there
has been any increase in tariffs since your previous account.

IF YOU HAVE CHECKED ALL THE FOREGOING AND STILL BELIEVE YOU
NEED ASSISTANCE, CALL YOUR NEAREST RHEEM SERVICE
DEPARTMENT OR ACCREDITED SERVICE AGENT.

INSTALLATION – SOLAR STORAGE TANK
THIS WATER HEATER IS FOR OUTDOOR INSTALLATION ONLY.
THIS WATER HEATER IS NOT SUITABLE FOR POOL HEATING.
Check the water heater is suitable for the gas type available.
(refer to the rating label on the water heater)
The system is suitable for installation with Rheem NPT 200 solar collectors.
The system is not suitable for installation above 400 metres altitude.
The system when installed in areas subject to freeze conditions must be
installed with the solar hot and solar cold pipes fully insulated with closed cell
polymer insulation (minimum thickness 13 mm) to offer protection against
freeze damage. Freeze conditions occur below 6°C. The system has NO
WARRANTY for freeze damage when installed above 400 metres altitude or if
the solar hot and solar cold pipes are uninsulated (refer to “Warranty
Exclusions” on page 59 and to “Warning: Plumber Be Aware” on page 38).
Thicker insulation may be required to comply with the requirements of
AS/NZS 3500.4.
SOLAR WATER HEATER STORAGE TANK LOCATION
The solar storage tank should be installed close to the most frequently used
outlet and its position chosen with safety and service in mind. Make sure
people (particularly children) will not touch the flue outlet. The flue terminal
must be clear of obstructions and shrubbery.
Consideration must also be given to the position of the solar storage tank in
relation to the solar collectors. There are limitations on the maximum length of
the solar hot and solar cold pipes between the solar storage tank and the solar
collectors. Refer to “Solar Collector Location” on page 36 and to “Pipe Lengths”
on page 37.
Clearance must be allowed for
servicing of the solar storage tank. The
solar storage tank must be accessible
without the use of a ladder or scaffold.
Make sure the temperature pressure
relief valve lever is accessible and the
access covers and burner can be
removed for service.
If possible leave headroom of one
water heater length so the anode can
be inspected or replaced. Remember
you may have to remove the entire
solar storage tank later for servicing.

INSTALLATION – SOLAR STORAGE TANK
The installation must comply with the requirements of AS/NZS 3500.4,
AS/NZS 3000, AS 5601 and all local codes and regulatory authority
requirements. In New Zealand, the installation must conform with NZS 5261
Code of Practice for Installation of Gas Burning Appliances and the New
Zealand Building Code.
The water heater must not be installed in an area with a corrosive atmosphere
where chemicals are stored or where aerosol propellants are released.
Remember the air may be safe to breathe, but when it goes through a flame,
chemical changes take place which may attack the water heater.
The solar storage tank is to be installed at ground level on a concrete or brick
plinth (fire proof base) and must stand vertically upright with the back of the
solar storage tank against an external wall or alternatively against a fireproof
screen extending at least 500 mm above, below and either side the flue
terminal. Failure to observe this precaution can cause problems in high wind
areas. A secondary flue is not required.
As a guide the following requirements extracted from the Australian Gas
Installations Standard AS 5601, must be observed:
•

At least 300 mm between the top of
the solar storage tank and the
eaves.

•

At least 500 mm between the solar
storage tank and the edge of any
opening into the building, measured
horizontally and vertically.

•

At least 500 mm between the solar
storage tank and a return wall or
external
corner,
measured
horizontally along the wall.

•

At least 500 mm
openable window.

•

At least 500 mm clear of any combustibles.

TANK WATER SUPPLY
If the water heater is supplied with water from a tank supply and a minimum
water supply pressure of 200 kPa at the water heater cannot be achieved, then
a pressure pump system must be installed to allow the solar circuit system to
operate. Care must be taken to avoid air locks. The cold water line from the
supply tank should be adequately sized and fitted with a full flow gate valve or
ball valve.

INSTALLATION – SOLAR STORAGE TANK
HOT WATER DELIVERY
This water heater can deliver water at temperatures which can cause scalding.
It is necessary and we recommend that a temperature limiting device be fitted
between the water heater and the hot water outlets in any ablution area such
as a bathroom or ensuite, to reduce the risk of scalding. The installing plumber
may have a legal obligation to ensure the installation of this water heater meets
the delivery water temperature requirements of AS/NZS 3500.4 so that scalding
water temperatures are not delivered to a bathroom, ensuite or other ablution
area.
Where a temperature limiting device is installed adjacent to the solar water
heater, the cold water line to the temperature limiting device can be branched
off the cold water line either before or after the isolation valve and pressure
limiting valve to the solar storage tank, but it MUST BE before the non return
valve. If an expansion control valve is required, it must always be installed after
the non return valve and be the last valve prior to the solar storage tank.
Warning: A non return valve MUST BE installed on the cold water line to
the solar storage tank AFTER the cold water branch to a temperature limiting
device. Due to the higher water temperatures generated under certain
conditions in the solar collectors of this solar water heater, an additional
effective back-flow prevention device also should be used as an extra
safeguard. Valve manufacturer RMC recommends Dual Check Valve model
N7150, as being suitable for this application.

Two Temperature Zones Using a Temperature Limiting Device

INSTALLATION – SOLAR STORAGE TANK
If a combination isolation valve and non return valve (duo or trio valve) is
installed on the cold water line to the solar water heater and the cold water line
to the temperature limiting device branches off after this valve, then a second
non return valve must be installed between the cold water branch and the solar
storage tank. Due to the higher water temperatures generated under certain
conditions in the solar collectors of this solar water heater, an effective backflow prevention device should be used as the second non return valve as an
extra safeguard. Valve manufacturer RMC recommends Dual Check Valve
model N7150, as being suitable for this application.
If a pressure limiting valve is installed on the cold water line to the solar water
heater and the cold water line to a temperature limiting device branches off
before this valve or from another cold water line in the premises, then a
pressure limiting valve of an equal pressure setting may be required prior to the
temperature limiting device.
CIRCULATED HOT WATER FLOW AND RETURN SYSTEM
A solar water heater should not be installed as part of a circulated hot water
flow and return system in a building. The benefits of solar gain will be
significantly reduced and energy gained from the sun lost through the pipe
work.
If a circulated flow and return system is required, it is necessary to bypass the
solar water heater and install a secondary water heater connected to the hot
water flow and return line and supplied from the solar water heater. The
secondary water heater must be a storage water heater able to provide a hot
water outlet temperature of at least 60°C. Note: The thermostat must always
be set to at least 60°C. Refer to the diagram on page 31.
Temperature Limiting Device
A temperature limiting device cannot be installed in circulated hot water flow
and return pipe work. The tempered water from a temperature limiting device
cannot be circulated. Where a circulated hot water flow and return system is
required in a building, a temperature limiting device can only be installed on a
dead leg, branching off the circulated hot water flow and return pipe.
If circulated tempered water were to be returned back to the water heater,
depending on the location of the return line connection on the water supply line
to the water heater, then either:

INSTALLATION – SOLAR STORAGE TANK
•

water will be supplied to the cold water inlet of the temperature limiting
device at a temperature exceeding the maximum recommended water
supply temperature, or

•

when the hot taps are closed no water will be supplied to the cold water
inlet of the temperature limiting device whilst hot water will continue to be
supplied to the hot water inlet of the temperature limiting device.

These conditions may result in either water at a temperature exceeding the
requirements of AS/NZS 3500.4 being delivered to the hot water outlets in the
ablution areas, or the device closing completely and not delivering water at all,
or the device failing. Under either condition, the operation and performance of
the device cannot be guaranteed.

Circulated Hot Water Flow and Return System – Solar Water Heater

REDUCING HEAT LOSSES
The cold water line to and the hot water line from the water heater must be
insulated in accordance with the requirements of AS/NZS 3500.4. The
insulation must be weatherproof and UV resistant if exposed.
The pipe work between the solar storage tank and the solar collectors must be
fully insulated with closed cell polymer insulation or similar (minimum thickness
13 mm). Thicker insulation may be required to comply with the requirements of
AS/NZS 3500.4. The insulation must be weatherproof and UV resistant if
exposed. The insulation must be fitted up to the connections on both the solar
storage tank and the solar collectors.

ASSEMBLY OF SOLAR HOT AND SOLAR COLD PIPE CONNECTIONS

•

Use thread sealing tape or approved thread sealant.

•

All olive compression fittings must use brass or copper olives.

•

Ensure air bleed valve is open when filling collectors.

•

Insulate the air bleed valve and 3 way tee assembly connected to the solar
hot pipe with the 150 mm long x 35 mm diam insulation and the solar non
return valve at the solar hot (from collector) inlet of the solar storage tank
with the 50 mm long x 35 mm diam insulation. Secure the insulation with the
cable ties supplied.

INSTALLATION – SOLAR COLLECTORS
SOLAR COLLECTOR LOCATION
Consideration must be given to the position of the solar collectors in relation to
the solar storage tank. There are limitations on the maximum length of the solar
hot and solar cold pipes between the solar storage tank and the solar
collectors. Refer to “Solar Storage Tank Location” on page 26 and to “Pipe
Lengths” on page 37.
•

The solar collectors must be installed in a shade free position.

•

The solar collectors are to be installed
facing toward the equator (i.e. north
facing in the southern hemisphere and
south
facing
in
the
northern
hemisphere). Where this orientation is
not practical, a system facing up to 45°
from the equator will have its efficiency
reduced by approximately 4%.

•

Inclination of the solar collectors should
be approximately equal to 90% of the
local latitude angle. The latitudes of
some Australian cities are listed on
page 37. Solar collectors may be
installed at the roof angle for simplicity
of installation and appearance, but must
never be flat. If the roof angle varies by
15° from the correct angle, efficiency
will be reduced by 10%.

•

For an installation on a roof with a pitch less than 10°, a Variable Pitch
stand is required. Refer to your local Solar Distributor for details.

•

For an installation at right angles to (across) the roof pitch, a Flat Roof stand
and an Across Pitch kit are both required. Refer to your local Solar
Distributor for details.

•

For an installation opposite to (against) the roof pitch, a Flat Roof stand and
an Against Pitch kit are both required. Refer to your local Solar Distributor
for details.

•

The collector kit is suitable for installations with an inclination of up to 30°.
Where the solar collectors are installed at inclinations greater than 30°, a
With Pitch frame is necessary. Refer to your local Solar Distributor for
details.

•

The roof must be suitable to take the mass of the solar collectors. Each
solar collector and its fittings weighs approximately 40 kg when full of water.

INSTALLATION – SOLAR COLLECTORS
•

The installation must comply with the requirements of AS/NZS 3500.4 and
all local codes and regulatory authority requirements.

Note: One 90° elbow is equal to two 90° bends.
NR – not recommended.

The solar hot and solar cold pipes between the solar storage tank and the solar
collectors should be a minimum DN15.
Maximum height to collectors
The maximum height of a solar Loline installation, from the solar controller
(circulator) to the top of the solar collectors, is determined by the maximum
recommended total pipe length for the system and the water supply pressure.
The maximum recommended total pipe length of the solar circuit should not be
exceeded and a minimum water supply pressure of 200 kPa should be
available at the inlet to the system, otherwise the system performance may be
reduced or the solar circuit may not be purged of air during the commissioning
of the system.

INSTALLATION – SOLAR COLLECTORS
WARNING: Plumber – Be Aware
•

The solar hot and solar cold pipes between the solar storage tank and
the solar collectors MUST BE of copper and fully insulated with closed
cell polymer insulation or similar (minimum thickness 13 mm). Thicker
insulation may be required to comply with the requirements of
AS/NZS 3500.4. The insulation must be weatherproof and UV resistant if
exposed. All compression fittings must use brass or copper olives.
Note: Failure to observe this requirement may void the warranty for
freeze damage.
The insulation is essential to assist in providing freeze protection, will
offer corrosion protection to a metal roof against water runoff over the
copper pipe, assist in avoiding accidental contact with the solar pipe work
and also reduce pipe heat losses.

•

The insulation must be fitted up to the connections on both the solar
collectors and the solar storage tank, as very high temperature water
can flow from the solar collectors to the solar storage tank under certain
conditions.

•

There must be a continuous fall in the pipe work between the solar
collectors and solar storage tank. The highest point of the solar cold pipe
and solar hot pipe must be where they connect to the solar collectors, to
avoid the possibility of air locks occurring in the system.

All pipe work must be cleared of foreign matter before connection and purged
before attempting to operate the water heater. All olive compression fittings
must use brass or copper olives. Use thread sealing tape or approved thread
sealant on all fittings.
An isolation valve and non return valve must be used on the cold water line to
the water heater. A non-return valve must be fitted on the cold water supply to
this water heater in compliance with Clause 5.9.1 of AS/NZS 3500.4. Due to
the higher temperatures generated by solar water heaters, an additional
effective back-flow prevention device also should be fitted as an extra
safeguard. Valve manufacturer RMC recommends Dual Check Valve No
N7150, as being suitable for this application.
An acceptable arrangement is shown in the diagram on page 40. Refer also to
“Hot Water Delivery” on page 29 and to “Mains Water Supply” on page 28. The
plumbing arrangements for the solar hot and solar cold pipes are shown on
page 35.

CONNECTIONS – PLUMBING

A disconnection union must always be provided at the cold water inlet, solar
cold water outlet, solar hot water inlet and hot water outlet on the water heater
to allow for disconnection of the water heater.
This water heater has either a
plastic dip tube or fitting liner in
the inlet and outlet fittings (see
diagram). These must be in place
for the water heater to function
properly. Do not remove or
damage them by using heat
nearby. They will be pushed into
the correct position as the fitting
is screwed in.
The solar cold pipe connects to the DN15 pipe protruding from the side of the
air duct on the solar storage tank. Use the compression fitting supplied. The
solar hot pipe connects to the raised inlet located above the cold water inlet
and below the hot water outlet (refer to “Assembly of Solar Hot and Solar Cold
Pipe Connections” diagram on page 35).
PIPE SIZES
To achieve true mains pressure operation, the cold water line to the water
heater should be the same size or bigger than the hot water line from the water
heater.
The pipe sizing for hot water supply systems should be carried out by persons
competent to do so, choosing the most suitable pipe size for each individual
application. Reference to the technical specifications of the water heater and
local regulatory authority requirements must be made.

CONNECTIONS – PLUMBING
RELIEF VALVE
The temperature pressure relief valve is shipped behind the front cover of the
solar storage tank. This valve must be fitted before the water heater is
operated. Before fitting the relief valve, make sure the probe has not been bent.
Seal the thread with Teflon tape - never hemp. Make sure the tape does not
hang over the end of the thread.
Screw the valve into the correct opening (refer to the installation diagram on
page 34) leaving the valve outlet pointing downwards. Do not use a wrench on
the valve body - use the spanner flats provided.
RELIEF VALVE DRAIN
A copper drain line must be fitted to the relief valve to carry the discharge clear
of the water heater. Connect the drain line to the relief valve using a
disconnection union. The pipe work from the relief valve to the drain should be
as short as possible and fall all the way from the water heater with no
restrictions. It should have no more than three right angle bends in it. Use
DN15 pipe.
The outlet of the drain line must be in such a position that flow out of the pipe
can be easily seen (refer to AS/NZS 3500.4) - but arranged so hot water
discharge will not cause injury, damage or nuisance. The drain line must
discharge at an outlet or air break not more than 9 metres from the relief valve.
In locations where water pipes are prone to freezing, the drain line must be
insulated and not exceed 300 mm in length. In this instance, the drain line is to
discharge into a tundish through an air gap of between 75 mm and 150 mm.
Warning: As the function of the temperature pressure relief valve on this
water heater is to discharge high temperature water under certain conditions, it
is strongly recommended the pipe work downstream of the relief valve be
capable of carrying water exceeding 93°C. Failure to observe this precaution
may result in damage to pipe work and property.

CONNECTIONS – PLUMBING
BLEED VALVE DRAIN
A copper drain line must be fitted to the bleed valve to carry the discharge clear
of the water heater and solar controls. Connect the drain line to the bleed valve
using a disconnection union. The pipe work from the bleed valve to the drain
should be as short as possible and fall all the way from the valve with no
restrictions. It should have no more than three right angle bends in it. Use
DN15 pipe.
The outlet of the drain line must be in such a position that flow out of the pipe
can be easily seen (refer to AS/NZS 3500.4) - but arranged so water discharge
will not cause injury, damage, nuisance or splashing. The water discharged
may be of a high temperature under certain conditions. The drain line must be
fully insulated with closed cell polymer insulation or similar (minimum thickness
13 mm). The insulation must be weatherproof and UV resistant if exposed.
EXPANSION CONTROL VALVE
Local regulations may make it mandatory to install an expansion control valve
(ECV) in the cold water line to the water heater. In other areas, an ECV is not
required unless the saturation index is greater than +0.4 (refer to “Water
Supplies” on page 56). However, an ECV may be needed in a corrosive water
area where there are sufficient quantities of silica dissolved in the water.
The expansion control valve must always be installed after the non return valve
and be the last valve installed prior to the water heater (refer to diagrams on
page 40). A copper drain line must be run separately from the drain of the relief
valve.
GAS INLET
The gas connection is made through the grommet in the left hand side panel to
the gas control. The pipe work must be cleared of foreign matter before
connection and purged before attempting to light the water heater. An isolation
valve and disconnection union must be used to allow servicing and removal of
the solar storage tank. Refer to the Gas Installations Standard AS 5601 for the
correct pipe sizing.
Warning: Always isolate the water heater before pressure testing the gas
supply system. Disconnect the water heater after the isolating cock to prevent
the risk of serious damage to the gas control. Warranty does not cover damage
of any nature resulting from failure to observe this precaution. Refer to rating
label for gas types and pressures.
Caution: Care is necessary when tightening fittings into the gas valve. The gas
valve casting may crack if the fittings are over tightened. Cracked valve
castings are not covered under warranty. Damaged valves must be replaced.

CONNECTIONS – ELECTRICAL
The power supply to the water heater must not be switched on until the
water heater is filled with water and a satisfactory megger reading is
obtained.
All electrical work and permanent wiring must be carried out by a qualified
person and in accordance with the Standards Australia Wiring Rules
AS/NZS 3000 and local authority requirements.
The water heater must be directly connected to a 240 V 50 Hz mains power
supply. The continuous power supply to the solar control unit and the timer
must be on the same circuit. A weatherproof double pole isolating switch must
be installed adjacent to and accessible from the solar storage tank in
accordance with AS 5601.
A flexible 20 mm conduit is required for the electrical cable to the solar storage
tank. The conduit is to be connected to the unit with a 20 mm terminator.
Connect the power supply wires directly to the terminal block, ensuring there
are no excess wire loops inside of the cover.
The terminal block on the solar storage tank has two active connections. One
active wire (marked “A”) is required for the operation of the solar control unit
and one active wire (marked “TIMER A”) is required for the operation of the gas
boosting system. The gas boosting system is switched by the timer.
Note:
•

It is essential the active to the solar control unit is not switched by the timer.

•

The timer is not weatherproof and must be installed indoors. It is
recommended the timer be located in the kitchen or laundry or other
location easily seen by the householder.

Connect the hot sensor lead from the solar collectors, through the hole in the
side of the air duct, to the hot sensor cable connector adjacent to the terminal
block. Fit the strain relief grommet over the hot sensor lead and secure at the
hole in the air duct.

COMMISSIONING
TO FILL AND TURN ON THE WATER HEATER
The power supply to the water heater must not be switched on and the
gas pilot or burner must not be lit until the water heater is filled with water
and a satisfactory megger reading is obtained.
•

Open all of the hot water taps in the house (don’t forget the shower).

•

Open the cold water isolation valve fully to the water heater.
Air will be forced out of the taps.

•

Close each tap as water flows freely from it.

•

Check the pipe work for leaks.

•

Bleed the solar collectors (refer to “Bleeding the Solar Collectors” on
page 46).

•

Switch on the electrical supply at the isolating switch to the water heater.
The isolating switch must be switched on for the solar control unit to operate
and solar gain to be achieved.

•

Program the timer (refer to “Timer Operation” on page 16).
Note: It is recommended the timer be set to enable boosting between
4:00 PM and 6:30 PM.

•

If necessary, press the timer “MAN” button to activate the “OVERRIDE”
function of the timer.
This will allow the gas control system to operate.

•

Open the gas isolation valve fully.

•

Check the gas pipe work for leaks.

•

Light the water heater (refer to “Lighting the Water Heater” on page 48).

•

When you are satisfied the main burner is operating correctly, press the
timer “MAN” button to deactivate the timer.
The main burner will extinguish.

COMMISSIONING
GAS INLET PRESSURE
IMPORTANT – CHECK the gas supply pressure at the inlet to the water heater
with the water heater and all other gas burning appliances in the premises
operating (burners alight). The minimum gas supply pressure is:
Natural Gas

1.13 kPa

Propane

2.75 kPa

Butane

2.75 kPa

If this minimum cannot be achieved, it may indicate the meter or the gas line to
the water heater is undersized. It is important to ensure that an adequate gas
supply pressure is available to the water heater when other gas burning
appliances, on the same gas supply, are operating.
BLEEDING THE SOLAR COLLECTORS
Upon completion of the installation, it is necessary to purge the air from the
collector circuit.
To purge air from the collector circuit:
•

Ensure the water heater is full of water and all of the hot taps are turned off.

•

Using a flat blade screwdriver,
open the bleed valve fitted
adjacent to the solar hot water
(from collector) inlet of the
solar storage tank (see
diagram).

•

The mains pressure will force
water to flow from the tank
and through the pipe work,
forcing air from the collector
circuit through the bleed
valve. This is evidenced by
spurting of water from the
drain line connected to the
bleed valve.
Warning: Exercise care to
avoid any splashing of water,
as water discharged from the
solar collectors may be of a
very high temperature.

•

Close the bleed valve when water runs freely from the drain line.

COMMISSIONING
TO TURN OFF THE WATER HEATER
If it is necessary to turn off the water heater on completion of the installation,
such as on a building site or where the premises is vacant, then:
•

Shut down the gas control (refer to “Close Down Procedure” on page 51).

•

Close the gas isolation valve at the inlet to the gas control.

•

Switch off the electrical supply at the isolating switch to the water heater
(refer to note below).

•

Close the cold water isolation valve at the inlet to the water heater.

Note: The freeze protection system will be rendered inoperable if electrical
power is not available. Damage caused by freezing due to the unavailability of
power to the water heater is not covered by warranty (refer to “Warranty
Exclusions” on page 59). If there is a risk of freezing, then it is necessary to
drain the solar collectors and connecting pipe work (refer to “Draining the Solar
Collectors” on page 52).

LIGHTING THE WATER HEATER
FOR YOUR SAFETY READ BEFORE LIGHTING
Warning: This gas water heater is designed to operate reliably and safely
as long as the operating instructions are followed exactly. You must comply
with these lighting instructions at every stage.
Make sure the water heater is filled with water and the water supply is on,
otherwise serious damage to the vitreous enamel cylinder lining and
plastic components may occur.
The installer must check all gas connections for leaks, gas supply pressure and
test point pressure (refer rating label). Remove the access cover at the front of
the water heater to access the gas thermostat.
Note: The main burner will only light when the word “ON” appears on the timer.
SAFETY INFORMATION
A.

This water heater is equipped with an igniter button which lights the pilot.
When lighting the pilot follow these instructions exactly.

Before lighting ensure there is no smell of gas around or in the vicinity of
the water heater and the burner opening. Be sure to smell next to ground
level as some gases can settle there.

What to do if you smell gas.
Do not try to light the water heater.
If the gas smell is throughout the area, turn the gas control knob clockwise
to the “z” (off) position and then turn off the isolation valve on the gas line
to the water heater. Leave the area and call Rheem Service or a qualified
service technician.

Use only your hand to turn the gas control knob, never use tools. If the
control knob will not turn by hand, don’t try to repair it, call a qualified
service technician. Force or attempted repair may cause a fire or
explosion.

Do not attempt to operate this water heater if it has been damaged. Call a
qualified service technician.

LIGHTING THE WATER HEATER
LIGHTING INSTRUCTIONS
Using the gas control light the water heater as follows:
1.

Stop, read the safety information on page 48.

Turn the gas control knob fully clockwise to the “z” (off) position.

Wait five (5) minutes so any build up of unburnt gas can escape. If you
then smell gas, stop and follow “C” in the safety information. If you do not
smell gas, proceed to step 4.

Turn the knob to the “·” (pilot) position.

Depress the knob fully (until star disappears below housing) and after
30 seconds, whilst keeping the knob depressed, repeatedly press the
igniter button (for up to 40 seconds) until the pilot flame ignites.
Warning: Keep your face clear of the combustion chamber opening
while pressing the igniter.
Note: It is not possible to depress the knob fully if the gas control has
activated its safety shut-off feature. In this case, wait 60 seconds for the
gas control to reset.

Keep the knob depressed for 20 seconds after the pilot flame lights. The
pilot can be checked by looking through the large opening below the gas
control.

Release the knob and check the pilot is still alight.

If the pilot has failed to light or has not remained alight, turn the gas control
knob to the "z” (off) position. Wait five (5) minutes for any unburnt gas to
escape and then begin again at step 3.
Warning: Failure to wait five (5) minutes may result in a fire or
explosion.

When the pilot flame remains alight with the gas control knob released,
turn the knob counter-clockwise to the setting of "6". This will give a water
temperature of about 60°C.
Rheem recommends the thermostat is set at 60°C to maximise solar
contribution.

10. Refer to “Temperature Adjustment” on page 5, if further adjustment is
required.
11. Replace the access cover.

LIGHTING THE WATER HEATER
The main burner will now automatically ignite during the set timer period when
heating is required and extinguish when the water has been heated to the set
temperature. If the main burner does not light at the selected setting, the water
may already be at the selected temperature.
Note: Never press the igniter button while the top knob is in a numbered
position.
TEST THE WATER HEATER AFTER INSTALLATION
•

The operation of the water heater must be thoroughly checked by the
installer.

•

The burner flame must light smoothly and quickly from the pilot flame, and
must go out quietly and completely.

•

The main burner flame must be stable, although slight lifting at the front
edge of the burner is acceptable when the burner is cold.

•

The main burner flame should be blue, with a clearly defined inner cone luminous yellow or "floating" flames are not acceptable, and must be
corrected by opening the air shutter (refer to “Air Shutter” on page 50).

•

Check the test point pressure and compare with the rating label. The
pressure regulator is not adjustable and if the test point pressure is not
within 5% of the specified value, refer to Rheem or their Accredited Service
Agent.

•

If unable to get the water heater working properly, contact the nearest
Rheem Service Department or their Accredited Service Agent.

•

When satisfied everything is working properly instruct the user in the correct
method of operation.

AIR SHUTTER
The air shutter is a hinged flap in the burner aeration tube. It may require
adjustment on installation.
•

For a Propane and Butane model, the air shutter should be fully open.

•

The shutter is held in place by a screw on the side of the burner aeration
tube.

Note: A Natural gas model does not have an air shutter.

LIGHTING THE WATER HEATER
CLOSE DOWN PROCEDURE
1.

Turn the gas control knob to the
“·” position (pilot). This setting
will leave the pilot flame alight
however the main burner will not
be able to light.

Turn the gas control knob to the
"z" (off) position. This setting
shuts the gas control down
completely.

DRAINING THE SOLAR COLLECTORS
To drain the solar collectors and the solar hot and solar cold pipes:
•

Open a hot water tap and allow the water to run for five minutes
immediately prior to draining the solar collector(s).
This will assist in the transfer of any high temperature water in the solar
collector(s) to the solar storage tank.

•

Close the hot water tap.
Warning: Exercise care, as water discharged from the solar collectors
may be of a very high temperature.

•

Turn off the water heater (refer to “To Turn Off the Water Heater” on
page 47).

•

Using a flat bladed screw driver, open the bleed valve fitted adjacent to the
solar hot water inlet of the water heater (refer to diagram on page 46).

•

Undo the compression fitting at the side of the air duct of the solar storage
tank and disconnect the solar cold pipe.
Water will now drain from the solar collectors and the solar hot and solar
cold pipes.

•

When water stops flowing from the solar hot and solar cold pipes, reconnect
the cold pipe to the solar storage tank and tighten the compression fitting.

•

Close the bleed valve.

DRAINING THE WATER HEATER
To drain the water heater:
•

Open a hot water tap and allow the water to run for five minutes
immediately prior to draining the solar storage tank.
This will assist in the transfer of any high temperature water in the solar
collector(s) to the solar storage tank.

•

Close the hot water tap.
Warning: Exercise care, as water discharged from the solar storage
tank may be of a very high temperature.

•

Turn off the water heater (refer to “To Turn Off The Water Heater” on
page 47).

•

Operate the relief valve release lever - do not let the lever snap back or you
will damage the valve seat.
Operating the lever will release the pressure in the water heater.

•

Attach a hose to the spout of the drain cock. Let the other end of the hose
go to a drain.

•

Open the drain cock using the handle.

•

Operate the relief valve again.
This will let air into the water heater and allow the water to drain through the
hose.

WATER SUPPLIES
Your water heater is manufactured to suit the water conditions of most
Australian metropolitan supplies. However, there are some known water
supplies which can have detrimental effects on the water heater and its
operation and/or life expectancy. If you are unsure of your water quality, you
can obtain information from your local water supply authority. The water heater
should only be connected to a potable water supply.
ANODE
In areas where the total dissolved solids (TDS) exceeds 600 mg/L it is possible
the black anode, which is the standard anode fitted to the water heater, may be
excessively active. To alleviate this, the black anode should be replaced with
one colour coded blue. Where the TDS of the water is less than 40 mg/L, such
as when the water has been deionised or is from an alpine supply, a high
potential anode, colour coded green, should be used. The changing of anodes
must be carried out by a plumber or authorised service person.
CAUTION
If your water supply has a TDS greater than 600 mg/L and the anode has not
been changed to a blue one, there is the possibility hydrogen gas could
accumulate in the top of the water heater during long periods of no use. In
areas where this is likely to occur, the installer should instruct the householder
on how to dissipate the gas safely.
If, under these conditions, the water heater has not been used for two or more
weeks the following procedure should be carried out before using any electrical
appliances (automatic washing machines and dishwashers) which are
connected to the hot water supply.
The hydrogen, which is highly flammable, should be vented safely by opening a
hot tap and allowing the water to flow. There should be no smoking or naked
flame near the tap whilst it is turned on. Any hydrogen gas will be dissipated.
This is indicated by an unusual spurting of the water from the tap. Once the
water runs freely again, any hydrogen in the system will have been released.

WATER SUPPLIES
SATURATION INDEX
The saturation index is used as a measure of the water’s corrosive or scaling
properties. In a corrosive water supply, the water can attack copper parts and
cause them to fail. Where the saturation index is less than –1.0, the water is
corrosive and warranty does not apply to a solar collector.
In a scaling water supply calcium carbonate is deposited out of the water onto
any hot metallic surface. Where the saturation index exceeds +0.40, the water
is scaling and an expansion control valve* must be fitted on the cold water line
after the non-return valve and the solar collectors should be covered when the
water heater is not intended to be used for more than two weeks. Where the
saturation index exceeds +0.80, warranty does not apply to a solar collector
unless a water softening device is installed.

* Refer to the cold water connection detail on page 40.
WATER HEATERS NOT INSTALLED IN ACCORDANCE WITH THE ABOVE
ADVICE WILL NOT BE COVERED BY THE WARRANTY.
