Installation Instructions
3. Before Installation
Do Not Use Equipment for Purposes Other Than Those Specified
•Do not use for other than increasing the temperature of the water supply, as unexpected accidents
may occur as a result.
Check Water Supply Quality
•If the water supply is hard, acidic or otherwise impure, treat the water with approved methods in
order to ensure full warranty coverage.
WARNING
CAUTION
Check the Gas
•Check that the data plate (located inside of front cover) or
a temporary label (located on the front cover)
indicates the correct type of gas.
•Check that the gas supply line is sized for
217 MJ/hr for this unit.
• DO NOT OPERATE WITH ANY OTHER GAS TYPE.
Check the Power
•The power supply required is 230/240VAC, at 50Hz.
Using the incorrect voltage may result in fire or
electric shock.
Warning labels
•Located on the right side of the casing -PLEASE READ THESE LABELS CAREFULLY!
Use Extreme Caution if Using With a Solar Pre-Heater
• Using this unit with a solar pre-heater can lead to unpredictable output temperatures and
possibly scalding. If absolutely necessary, use mixing valves to ensure output temperatures do
not get to scalding levels.

Installation Instructions
4. Choosing Installation Site
* Locate the appliance in an area where water leakage from the unit or connections will not result in
damage to the area adjacent to the appliance or to the lower floors of the structure. When such
locations cannot be avoided, it is recommended that a suitable drain pan, adequately drained, be
installed under the appliance. The pan must not restrict combustion air flow.
DANGER
• Avoid places where fires are common, such as those where petrol,
benzene and adhesives are handled, or places in which corrosive gases
(ammonia, chlorine, sulfur, ethylene compounds, acids) are present.
May result in fire.
•Avoid installation in places where dust or debris will accumulate.
Dust may block the air-supply opening, causing the performance of the
device fan to drop and incomplete combustion to occur as a result.
•Avoid installation in places where special chemical agents
(e.g., hair spray or spray detergent) are used.
Ignition failures and malfunction may occur as a result.
• Carbon Monoxide Poisoning Hazard. Do not install this water heater in a
mobile home, recreation vehicle or on a boat.
WARNING
• Install the exhaust vent so that there are no obstacles around the termination and so that exhaust
can't accumulate. Do not enclose the termination with corrugated metal or other materials.

5. Installation Clearances
Before installing, check for the following:
The location of the flue terminal must comply with the clearances shown on this page. If you are
unsure about clearances not indicated here, in general refer to AS5601, or your local authority. In
Western Australia refer to the WA Office of Energy rules and regulations.
Flue outlet must be free from any combustible material.
WARNING
•Install the water heater in a location where it is free from obstacles and
stagnant air.
•Consult with the customer concerning the location of installation.
•Do not install the water heater near staircases or emergency exits.
•Do not install the water heater where the exhaust will blow on outer
walls or material not resistant to heat. Also consider the surrounding
trees and animals.
The heat and moisture from the water heater may cause discoloration
of walls and resinous materials, or corrosion of aluminium materials.
•Do not locate the vent termination directed towards a window or any
other structure which has glass or wired glass facing the termination.
•Avoid installation above gas ranges or stoves.
• Avoid installation between the kitchen fan and stove. If oily fumes or a large
amount of steam are present in the installation location, take measures to
prevent the fumes and steam from entering into the equipment.
•Install in a location where the exhaust gas flow will not be affected by
fans or range hoods. See AS5601.
• Take care that noise and exhaust gas will not affect neighbours.
• Make sure that the location allows installation of the exhaust vent as
specified.
•For outdoor installation, use the outdoor vent cap.
•Avoid installation where the unit will be exposed to excessive winds.
•Before installing, make sure that the vent termination will have the
proper clearances according to AS5601, or your local authority.
•On combustible surfaces e.g. weatherboards etc. it is not required to
install a fire proof back board.
CAUTION

Installation Instructions
Item
Distance from combustibles
• Maintain the following clearances
from both combustible and
non-combustible materials.
• If the unit will be installed in the vicinity of
a permanent kitchen range or stove that
has the possibility of generating steam
that contains fats or oils, use a dividing
plate or other measure to ensure that the
unit is not exposed to air containing such
impurities.
* The dividing plate should be noncombus-
tible and the width must exceed that of
the device.
* Do not remove mounting brackets to
reduce air gap at rear.
In Accordance with AS5601
•Maintain the following clearances to any
opening in any building:
1.5m below and 500mm horizontally from
any door, window or gravity air inlet. 1m
above any forced air inlet.
500mm below an overhang.
In accordance with AS5601

4. Drill holes for the remaining four screws.
5. Hang the unit again by the first screw, and then
insert and tighten the remaining four screws.
6. Take waterproofing measures so that water does
not enter the building from screws mounting the
device.
•Make sure the unit is installed securely so that it will
not fall or move due to vibrations or earthquakes.
Securing to the wall
1. Drill a single screw hole, making sure to hit a stud.
2. Insert and tighten the screw and hang the unit by
the upper wall mounting bracket.
3. Determine the positions for the remaining four screws
(two for the top bracket and two for the bottom), and
remove the unit.
•Installation must conform with all local building, water or Gas Regulations or AS5601.
• The weight of the device will be applied to the wall. If the strength of the wall is not suffi-
cient, reinforcement must be installed to prevent the transfer of vibration.
•Do not drop or apply unnecessary force to the device when installing. Internal parts may
be damaged and may become highly dangerous.
• Install the unit on a vertical wall and ensure that it is level.

Installation Instructions
Filling the neutralizer unit with water
The neutralizer unit must be filled before connecting the vent pipe.
Filling the neutralizer unit before vent pipe installation.
DANGER
Prior to initial start up, make sure that you fill the neutralizer unit with water.
This is to prevent dangerous exhaust gases from entering the building.
Failure to fill the neutralizer unit could result in severe personal injury or death.
Please follow one of the procedures described below to ensure that the neutralizer unit is filled with water.
1) Fill the neutralizer unit by pouring approx. 500ml of water into the
exhaust accessory on the top of the appliance as illustrated below.
Or, if the vent pipe has already been installed:
2) After installing the drain pipe, make sure that the area around the
appliance is well ventilated; open a window or a door if necessary.
Then, operate the unit and verify that condensate is coming out of
the drain pipe.
(During normal use of the water heater, condensate will begin to
discharge from the drain pipe within 15 minutes of use. However,
depending on the season and/or installation site conditions, it may
take longer.)
