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
sacricial anode, accessible through the
top cover. Allow 50% of the height of
the water heater for clearance above to
replace the anode.

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, 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.
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.
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).
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.
Danger: Failure to operate the relief
valve easing lever at least once every six
(6) months may result in a problem with
the water heater and in some cases the
tank may explode.
Warning: A separate drain line must be
run for this relief valve. It is not permitted
to couple drain lines from relief valves
into a single common drain line.
Cold Water Connection
An approved isolating valve, non
return valve, line strainer (optional but
recommended), and union must be
tted between the supply main and
either of the RP¾/20 sockets marked
“INLET” at the bottom of the water
heater. All ttings must be approved by
the relevant Authority. See the diagram
on page 5 for details.
Note: Brass plugs are supplied with
the water heater to plug off the unused
ttings. Ensure that a sealing material is
applied to the plugs to prevent leaking.
Note for S.A. and W.A.: It is a state
requirement that a Expansion Control
Valve be tted on the cold water supply
line between the non return valve and
the water heater. See the diagram on
page 6 for details.

Hot Water Connection
The hot water pipe should be connected
to either of the RP¾/20 sockets marked
"OUTLET" at the top of the unit. Please
check local regulations regarding the
use of hot water supply pipework that is
not made of copper.
Insulation of Pipes
For the most economical operation of
the water heater, it is recommended
that all hot water lines are insulated.
Where the hot water pipes are installed
outdoors, the insulation should be UV
stabilised.
Note: a combined isolating valve/non-return valve/line strainer may be used.
Expansion Control Valve only required where local regulations demand although it is
recommended in areas where the water saturation index is above 0.40 (see page 11).

Temperature Protection
Water heaters can produce very hot
water. 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 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.
