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.

Fit the insulation supplied with the water

heater to the PTR Valve, after the PTR

is installed. Ensure the PTR lever is not

obstructed by the tment of the insulation.

See below.

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.

Plumbing Connections

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.

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 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 and Filling

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.

Owner’s Manual – Prodigy 4 & 5

8H3109 3109 Rev. L

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.

Important Safety Note:

Do not look directly into the

burner area. Keep your head above the

top of the access cover opening. Use a

mirror to observe the ame.

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. Use a mirror to observe

the pilot ame. Do not attempt to

observe the ame directly.

7. Release the control knob and check

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.

12. Replace the access cover and ensure

it is rmly in position.
