Installation Requirements
Water Heater Support:
The water heater must be installed on a
at, solid, non-combustible supporting
surface. The weight of the water heater
should not cause deformation to any
part of the building structure.
It is recommended that a plinth is
installed under the water heater.
The water heater must be installed
plumb and level.
The water heater must also be secured
to a durable structure using the wall
brackets supplied loose with the water
heater. Note that the gas or water
pipework must not be used to support
the water heater.
The wall brackets are designed to be
installed on each side of the water
heater with the long leg against the side
of the water heater and the short leg
against the wall. The brackets should be
located near the top of the water heater,
approximately in line with the Outlet
and Relief Valve sockets. Note that
once installed, the brackets should not
obscure any labels on the water heater.
The brackets should be xed to the wall
with suitable fasteners and xed to the
water heater with the self drilling screws
provided.
Water Supply:
This water heater has been
manufactured to suit the water
conditions of most Australian
metropolitan supplies.
Please note that certain water supplies
can have a detrimental effect on the
water heater and its life expectancy. If
you are unsure about the water supply
you can obtain information from the
local water supply authority.
The water heater is designed for use in
areas where the Total Dissolved Solids
(TDS) content of the water supply is
less than 2500 mg/L. The Tank Failure
Warranty does not apply in areas where
the TDS exceeds 2500 mg/L.
In areas where the TDS exceeds
600mg/L it is possible that the
magnesium alloy anode (supplied in
standard water heaters) may become
overreactive. To alleviate this, the
magnesium anode should be replaced
with an aluminium alloy anode.
Aluminium alloy anodes are available
from your local Dux Supplier.
Water can also be very corrosive, the
measure of this is the saturation index.
If the water saturation index is greater
than 0.40, an expansion control valve
should be tted. Please consult Dux
After Sales and Service for advice if
required.

Relief Valve:
The Pressure & Temperature Relief (PTR)
Valve is supplied loose with the water
heater.
The PTR Valve rating is 1400 kPa.
The PTR Valve rating is also shown
on the compliance plate. The PTR
Valve must be installed directly into the
RP½”(DN15) socket marked “RELIEF
VALVE” at the top of the water heater on
the right hand side.
Ensure that a sealing material is applied
to the PTR Valve to prevent water leaks.
The drain line from this valve must be
made of copper and run in
accordance with the requirements of
AS/NZS 3500.4.
The PTR Valve and its drain outlet
pipe must not be sealed or blocked.
A separate drain line must be run for
the valve. It is not permitted to couple
drain lines from relief valves into a single
common drain line.
It is normal for the valve to leak a small
amount of water during heating cycles.
The PTR Valve is not intended to enable
connection of the water heater to
supplementary energy sources such as
solar panels or slow combustion stoves.
Refer to AS/NZS 3500.4 for guidance
on these types of installations.
Caution:
Care must be taken when attaching
pipe saddles to the water heater. We
recommend the use of self drilling
screws no longer than 12 mm.
Hot Water Connection:
The hot water pipe is to be connected
into the RP¾”(DN20) socket marked
“OUTLET” at the top of the water heater
on the left hand side.
It is recommended that all hot water
pipes are insulated. Hot water pipes
installed outdoors should be insulated
with UV stabilised insulation.
Plastic pipes or ttings shall not be used
within 1 metre of the outlet although
they may be used downstream of a
temperature control valve. Refer to
AS/NZS 3500.4 for further details.
Temperature Protection:
Water heaters can produce very hot
water. To reduce the risk of scald injury,
it is mandatory under the requirements
of AS/NZS 3500.4 that an approved
temperature control device be tted to
the hot water supply to outlets used
primarily for personal hygiene. This valve
should be checked at regular intervals to
ensure its operation and settings remain
correct.

Plumbing Connections
Cold Water Connection:
The water heater is intended to be
permanently connected to the water
supply main.
An approved isolating valve, non-
return valve, line strainer (optional but
recommended) and union must be tted
between the water supply main and the
RP¾”(DN20) socket marked “INLET” at
the bottom of the water heater on the
left hand side.
All ttings must be approved by the
relevant Authority. Plastic pipes or
ttings shall not be used between the
isolating valve and the inlet.
See the diagram below for details.
Water Supply Pressure:
This water heater is designed for direct
connection to water supply pressures of
up to 1120 kPa.
Where the mains pressure can exceed
or uctuate beyond the pressure shown
above, a pressure reducing valve must
be tted in the cold water inlet supply.
Note for New Zealand, South
Australia and Western Australia:
It is a requirement in these locations that
an expansion control valve be tted on
the cold water supply line between the
non-return valve and the water heater.
Note: a combined isolating valve/non-return valve/line strainer may be used.
The expansion control valve is only required where local regulations demand,
although it is recommended in areas where the water saturation index is greater
than 0.40.

Gas Connection:
Ensure that the gas type to be
connected matches the gas type
marked on the compliance plate of the
water heater.
The gas pipe should be sized in
accordance with AS/NZS 5601.1.
An isolation valve must be installed in
the gas pipe before it enters the water
heater.
The gas pipe must be connected via the
gas entry hole on the left hand side of
the water heater. See Specications on
page 4 for the location of the entry hole.
Ensure that the black plastic grommet,
supplied loose with the water heater,
is slid over the gas pipe before the
connections are completed. The
grommet must then be clipped into the
case.
A union should be used to connect the
gas pipe to the RP½” (DN15) socket on
the gas control valve. Ensure that the
union is not over-tightened in the gas
control valve.
The water heater must be lled with
water before lighting the gas.
Filling the Water Heater:
1. Open all hot water taps.
2. Open the isolating valve at the cold
water inlet slowly and allow the
water heater to ll until water ows
through the system.
3. Close each hot water tap after the
air is expelled from its line.
4. Open the Pressure & Temperature
Relief Valve for approximately
10 seconds by lifting the easing
lever on the valve. Conrm that
water drains to waste through the
relief valve drain pipe.
5. Lower the lever gently and check
that it closes correctly.

H3071 3071 Rev. K
Caution:
Do not light the water heater until it has
been lled with water (see Filling the
Water Heater on page 7).
Do not attempt to light the water heater
if the pilot is out and the knob is in
the “ON” position (one of the number
settings). Follow the steps below.
Lighting Procedure:
The diagram on the next page shows
the location of the control knob and the
igniter button on the gas control valve.
1. Remove the access cover. (A copy of
the lighting procedure can also be
found on the inside of the access
cover).
2. Turn the control knob fully clockwise to
the “•” (off) position.
3. Wait ve (5) minutes so any build up of
unburnt gas can escape.
4. Turn the control knob to the (pilot)
position.
5. Depress the control knob fully (until
disappears below housing) and after
thirty (30) seconds, whilst keeping the
control knob depressed, repeatedly
press the igniter button (for up to 40
seconds) until the pilot ame ignites.
Note - it is not possible to depress the
control knob fully if the gas control valve
has activated its safety shutoff feature.
In this case, wait sixty (60) seconds for
the gas control valve to reset.
6. Keep the control knob depressed for
twenty (20) seconds after the pilot
ame lights. The pilot ame can be
observed if a mirror is placed directly
below the pilot assembly.
7. Release the control knob and check
that the pilot is still alight.
8. If the pilot has failed to light or has not
remained alight, turn the control knob
to “•” (off). Wait ve (5) minutes for the
escape of unburnt gas, then begin
again at step 4.
9. When the pilot ame remains alight
with the control knob released, turn
the control knob anticlockwise to one
of the number settings. A minimum
setting of “6” is recommended and
this will give a water temperature of
about 60°C.
10. Turn the control knob to a
higher number for higher water
temperatures.
11. If the main burner does not light
at the selected setting, the water
may already be at the selected
temperature.

The operation of the water heater
must be tested by the installer. This
work must only be done by a licensed
tradesperson.
Test for Leaks:
Check the water inlet, water outlet and
gas inlet pipe work and connections for
leaks.
Test the Gas Inlet Pressure:
For correct operation of the water
heater, the gas inlet pressure must be at
least:
Natural Gas 1.13 kPa
Propane 2.75 kPa
To test the gas inlet pressure, follow the
procedure below. If the pressure is less
than the above value, there could be a
problem with the gas meter or supply
pipe size.
1. Ensure that the water heater has
been lled with water and that the
gas isolation valve is turned off.
2. Remove the lower of the two hex
head screws on the right hand side
of the gas control valve and t a
manometer to the spigot.
3. Turn on the gas isolation valve and
light the water heater. See Lighting
the Water Heater on page 8.
4. If necessary, adjust the control knob
until the main burner lights.
5. With the main burner alight,
measure the pressure.
6. Turn the thermostat knob to the “•”
(off) position and turn off the gas
isolation valve.
7. Disconnect the manometer and
replace the hex head screw
removed at step 2.
Test the Gas Test Point Pressure:
For correct operation of the water
heater, the gas test point pressure must
be within 5% of the value marked on the
compliance plate.
To test the gas test point pressure,
follow the same procedure used for the
gas inlet pressure except that the upper
of the two hex head screws is to be
removed at step 2.
If the pressure is not within 5% of the
marked value, contact Dux After Sales
and Service for advice.
Final Checks:
• Turn on the gas isolation valve and
light the water heater.
• Make sure that there are no gas
leaks from either of the two hex
head screws.
• Set the gas control knob to position
“6” unless hot water is not required.
• Replace the access cover.
• Hand this manual to the occupier of
the premises and explain the lighting
procedure if required.

Owner’s Information
Safety:
This water heater is not intended for
use by persons (including children) with
reduced physical, sensory or mental
capabilities, or lack of experience and
knowledge, unless they have been given
supervision or instruction concerning
use of the water heater by a person
responsible for their safety.
Children and animals should be
supervised to ensure that they do not
interfere with the water heater.
DO NOT spray aerosols in the vicinity of
this water heater while it is operating.
DO NOT use or store ammable
materials or chemicals in or near this
water heater.
DO NOT place articles on or against this
water heater.
DO NOT modify this water heater.
DO NOT operate the water heater with
any panels or covers removed.
Relief Valve:
The Pressure & Temperature Relief (PTR)
Valve must be installed directly into the
top socket marked “RELIEF VALVE”.
The PTR Valve rating is shown on the
compliance plate. The valve must not be
tampered with or removed. The water
heater must not be operated unless this
valve is tted and in working order.
The PTR Valve should be checked by
a licensed tradesperson for adequate
performance, or replaced at intervals
not exceeding 5 years, or less in areas
where local regulations apply.
The PTR Valve is to be operated
regularly to remove lime deposits and to
verify that it is not blocked. It is normal
for the valve to leak a small amount of
water during heating cycles.
Danger:
Failure to operate the PTR Valve easing
lever at least once every six months may
result in the water heater failing.
Continuous leakage of water from the
PTR Valve may indicate a problem with
the water heater. This may be caused
by excessive water supply pressure, a
faulty PTR Valve or a faulty Gas Control
Valve.
Shut down the water heater and contact
Dux After Sales and Service.

Owner’s Information
Gas Control Valve:
As well as acting as a thermostat, the
gas control valve is tted with over
temperature energy cut-outs.
The gas control valve must not be
tampered with or bypassed.
Replacement of the gas control valve
must only be carried out by a licensed
tradesperson or the manufacturer.
The water heater must not be operated
unless the gas control valve is tted and
in working order.
Temperature Protection:
Water heaters can produce very hot
water. To reduce the risk of scald
injury, it is mandatory that an approved
temperature control device be tted to
the hot water supply to outlets used
primarily for personal hygiene. This
device should be checked at regular
intervals to ensure its operation and
settings remain correct.
Not Using Hot Water?
If you are not expecting to need hot
water for more than a few days, the
control knob on the gas control valve
thermostat can be set to the (pilot)
position to conserve energy. Alternatively,
the water heater can be shut down.
If the water heater is not used for two
weeks or more, a quantity of hydrogen
(which is highly ammable) may
accumulate inside the water heater tank.
To dissipate this gas safely it is
recommended that a hot tap be turned
on for several minutes at a sink, basin
or bath, but not a dishwasher, clothes
washer or other appliance.
During this procedure there must be
no smoking, open ame or any other
electrical appliance operating nearby. If
hydrogen is discharged through the tap
it will probably make a sound similar to
that of air escaping.
Water Heater Appears to be
Leaking:
If the water heater is heating a large
quantity of cold water, condensation
may form inside the water heater and
drip down onto the burner.
This is NOT an indication that the water
heater is leaking, but is the result of an
efcient gas combustion process.

System Maintenance
Regular servicing will help to keep
the water heater operating safely and
efciently.
Six Month Service:
This service may be carried out by the
owner.
1. Stand clear of the Pressure &
Temperature Relief (PTR) Valve drain
pipe outlet.
2. Open the PTR Valve for
approximately 10 seconds by
lifting the easing lever on the valve.
Conrm that water discharges to
waste through the drain pipe.
3. Lower the easing lever gently and
check that it closes correctly.
4. Repeat the above process for the
expansion control valve (if installed).
Other than this, personally inspecting or
servicing any part of the water heater is
not recommended.
Annual Service:
This service should only be carried
out by a licensed tradesperson. We
recommend your local Dux Service
Agent.
The service should include the following:
• Inspect and ush PTR Valve and
expansion control valve (if installed).
• Check the spark gap, gas control
valve and thermocouple.
• Check and if necessary adjust the
main burner pressure.
• Clean and check the main burner
and the pilot light.
Five Year Service:
This service should only be carried
out by a licensed tradesperson. We
recommend your local Dux Service
Agent.
In locations where the water has Total
Dissolved Solids (TDS) exceeding 600
mg/L, this service is recommended
every 3 years.
In addition to the items listed in the
Annual Service, this service should
include the following:
• Replace the PTR Valve.
• Replace the anode.
• Drain and ush the water heater.

Owner’s Manual – Prodigy 4

H3071 3071 Rev. K
Considering a Service Call?
It is recommended that the following
points be reviewed before making a
service call:
No Hot Water:
Conrm the pilot is alight. If it is not, see
Lighting the Water Heater on page 8.
High Gas Bills or Insufcient Hot
Water:
• Consider that often the hot water
usage of showers, washing
machines and dishwashers can
be under estimated. Review these
appliances to determine if the daily
usage is greater than the capability
of the water heater.
• If necessary check the shower ow
rates with a bucket, measuring
the amount of water used over a
period of time. If it is not possible
to adjust water usage patterns, an
inexpensive ow control valve can
easily be tted to the shower outlet.
• Is the water heater the correct size
for the requirements? Sizing details
are available from your Dux supplier.
• Is there a leaking hot water pipe or
dripping hot water tap? A small leak
can waste a large quantity of hot
water. Replace faulty tap washers
and arrange for your plumber to
rectify any leaking pipe work.
• Is the Pressure & Temperature Relief
Valve discharging too much water?
See below.
Continuous Trickle of Water from
Pressure & Temperature Relief (PTR)
Valve:
This is most likely due to a build up of
foreign matter. In this case, try gently
raising the easing lever on the PTR Valve
for a few seconds, then release gently.
This may dislodge a small particle of
foreign matter and rectify the fault.
Water Discharge from PTR Valve:
It is not unusual for a small quantity of
water to discharge during the heating of
water in the storage tank. The amount
of discharge will depend on hot water
usage and the size of the storage tank.
As a guide, it will discharge about 2% of
the volume of the water heated.
Continuous leakage of water from the
PTR Valve may indicate a problem with
the water heater. Shut down the water
heater and contact Dux After Sales and
Service.
If after checking the above points,
the problem has not been identied,
please contact Dux After Sales and
Service.

Consequential Losses:
Claims for damage to furniture,
carpets, walls, foundations or any other
consequential loss either directly or
indirectly due to defects of any kind in
the water heater will only be met by Dux
where the damage could be considered
reasonably foreseeable and the water
heater was installed in accordance
with the installation instructions and all
relevant statutory requirements.
The Australian Consumer Law
(“ACL”):
Our goods come with guarantees that
cannot be excluded under the Australian
Consumer Law. You are entitled to
a replacement or refund for a major
failure and compensation for any other
reasonably foreseeable loss or damage.
You are also entitled to have the goods
repaired or replaced if the goods fail to
be of acceptable quality and the failure
does not amount to a major failure.
If Dux fails to meet a guarantee under
the ACL, your remedy for such failure
may be limited to any one or more of the
following:
• replacement of the water heater;
• repair of the water heater;
• refunding the cost of the water
heater;
• payment of the reasonable costs of
having the water heater repaired;
• payment in respect of the reduced
value of the water heater.
