Pool Heating
This water heater must not be used for
pool heating.
Installation Requirements
This water heater must be installed
by a licensed tradesperson, and in
accordance with:
• AS/NZS3500.4 “National Plumbing
and Drainage Code Hot Water
Supply Systems – Acceptable
Solutions”.
• AS5601/AG601 “Gas Installations”.
• Local authority regulations.
• Outside Australia and New Zealand,
please refer to local plumbing and
building codes and regulations.
• 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 certicate, showing
that the work complies with all
the relevant Standards and only a
licensed person will have insurance
protecting their workmanship for 6
years.
Outdoor Tank Installation
The water heater must be installed
outdoors, with the minimum clearances
as shown in the gure below.
A = 500mm B=300mm min
For further details, refer to
AS 5601 – Gas Installation Code
We recommend a re-proof plinth
be installed under the water heater.
Minimum clearance around the windows
and doors must be maintained – refer to
AS 5601.
Location
The water heater should be located as
close as possible to the most frequently
used hot water outlet. Ensure that the
data label is clearly visible and that there
is adequate access for servicing the unit.
Note: All models are equipped with a
sacricial anode, accessible through the
top cover. Allow 50% of the height of

H3958 026271 Rev. A
the water heater for clearance above to
replace the anode.
A properly drained overow tray must
be used where property damage
could occur from water spillage. (See
AS/NZS3500.4.2 for further details).
Warranty does not cover consequential
damage due to heater leakage.
Water Supply Pressure
This water heater is designed for direct
connection to water supply pressures of
no greater than:
All Models – 1120kPa
Where the mains pressure can exceed
or uctuate beyond the pressure
shown above a pressure limiting device
(complying with AS1357) must be
tted in the cold water inlet supply.
This device must be installed after
the isolating valve and set below the
pressure shown above. Note during
periods of lower demand water pressure
may increase.
Pressure & Temperature Relief
Valve
The Pressure & Temperature Relief Valve
is supplied loose with the water heater.
The valve rating is:
All Models – 1400kPa
The PTR valve must be installed directly
into the top socket marked “RELIEF
VALVE”. The drain line from this valve
must run in a continuously downward
direction in a frost-free ambient position
with the discharge end left open to
atmosphere permanently.
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 AS/NZS 3500.4 for guidance on
these types of installations).
Open the PTR Valve for approximately
10 seconds by lifting the lever on the
valve to ensure water is relieved to waste
through the relief drain pipe. Lower lever
gently and check that it closes correctly.
Warning: We recommend that you
open the PTR valve at least once every
6 months. Failure to do this may result in
problems with the water heater.
The PTR 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 for
adequate performance or replaced at
intervals not exceeding 5 years, or less
in areas where local regulations apply.
Important: The PTR Valve and its
drain outlet pipe must not be sealed or
blocked. It is normal for the PTR valve
to leak a small amount of water during
heating cycles.
Plumbing Connections
Owner’s Manual – Gas Storage
4H3958 026271 Rev. A
Cold Water Connection
It is mandatory to t the following items
between the supply main and the
RP¾"/20mm socket in the water heater.
• an isolating valve
• a non return valve
• a line strainer
• a union
All ttings must be approved by the
relevant Authority and in accordance to
the plumbing code.
Note for S.A. and W.A.: It is a state
requirement that a pressure relief
valve be tted on the cold water
supply line between the non re-
turn valve and the water heater.
Hot Water Connection
The hot water line should be connected
to the “OUTLET” socket on the tank.
Insulation of Pipes
All hot water pipes must be insulated
with UV stabilized insulation.
Temperature Protection
All water heaters have the ability to
produce hot water very quickly. To
reduce the risk of scald injury, it is
mandatory under the requirements of
Australian Standard AS/NZS3500.4.2
that a suitably approved temperature
control device, such as a tempering
valve, be tted to the hot water supply
to outlets used primarily for personal
hygiene.
Plumbing Connections
Note: a combined isolating valve/non-return valve/line strainer may be used.

2. Wait 5 minutes so any build-up of
unburnt gas can escape.
3. Turn the knob to the (pilot)
position.
Thermostat and
gas control knob Igniter
4. Depress the knob fully (until
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 ame ignites.
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.
5. Keep the knob depressed for 20
seconds after the pilot ame lights.
The pilot ame can be observed if
a mirror is placed directly below the
pilot assembly.
6. Release the knob and check if the
pilot is still alight.
7. If pilot has failed to light or has not
remained alight, turn gas control
knob to “•” (off). Wait 5 minutes for
the escape of unburnt gas, then
begin again at step 3.
8. When the pilot ame remains alight
with the knob released, turn the
knob anticlockwise to one of the
number settings. A setting of “6” is
recommended and this will give a
water temperature of about 60ºC.
9. Turn the knob to a higher number
for higher water temperatures or
a lower number for lower water
temperatures.
10. Set the test point pressure as
per the instructions on page 8.
11. Replace the access panel and
ensure that it is rmly in position
before operating the appliance.
12. If the burner does not light at
the selected setting, the water

Main Gas Pressure Regulator
Adjustment
The main burner pressure must be
set at installation in accordance
with that marked on the Data
Plate. Adjust the Gas Control as
required to achieve specied gas
test point pressure. If problems are
encountered in this process contact
the Dux Service Department.
Failure to accurately set the pressure can
result in damage to the water heater, and
automatically cancels the Manufacturer’s
Warranty. This water heater is to be
installed only by an Authorised Person.
The pressure is best checked by
connecting a water manometer or
equivalent to the test point nipple. The
test point pressure must comply
with the value on the Data Label.
If adjustment is necessary, follow the
instructions below:
1. Remove the securing screw (1) from
the top of the Gas Control and lift
the plastic cover (2) upwards.
2. Locate the regulator adjustment
screw on the lower left hand side of
the Gas Control (3).
3. Light the burner. Rotate adjustment
screw clockwise to increase, or anti-
clockwise to decrease pressure.
4. Replace the plastic cover and
securing screw.
5. Replace the test point nipple
blanking screw and test for gas
leaks.
