Installation Details
Outdoor Tank Installation
The water heater must be installed
outdoors, with the minimum clearances
as shown in the gure below.
We recommend a plinth be installed
under the water heater where the
water heater is subjected to wet
conditions.
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
sacricial anode, accessible through the
top cover. Allow 50% of the height of
the water heater for clearance above to
replace the anode.
A properly drained overow tray must
be used where property damage could
occur from water spillage. (See
AS/NZS3500.4 for further details).
Warranty does not cover consequential
damage due to heater leakage.
Safety
This appliance 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 appliance by a person
responsible for their safety.
Children and animals should be
supervised to ensure that they do not
interfere with the appliance.

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 certicate, showing
that the work complies with all
the relevant Standards and only a
licensed person will have insurance
protecting their workmanship for 6
years.
Water Supply Pressure
This water heater is designed for direct
connection to water supply pressures of
no greater than:
All Litre 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.
Pool Heating
This water heater must not be used for
pool heating.

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
six (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.
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 return 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 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.

Lighting the Water Heater
The water heater must be lled with
water before lighting. Instructions for
lighting procedure are on the inside of
the access cover and shown below:
1. Turn the knob fully clockwise to the
“•” (off) position.
2. Wait ve (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
thirty (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
twenty (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 ve (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.
