Installation
Install in accordance with AS5601, AS/NZS3500.4.2,
NZS5261 and all local building, water and gas fitting regu-
lations.
3.1
General Remarks
Any local by-laws and regulations pertaining to installation
and use of gas-heated appliances must be observed.
3.2
Location
The appliance should be installed in a frost-protected, well
ventilated room, as near as possible to the most frequently
used tap. In order to prevent corrosion, make sure that the
combustion air is kept free of aggressive substances.
Substances that especially contribute to corrosion are
halogenated hydrocarbons (e.g chlorine, fluorine), which are
contained in solvents, paint, adhesives, propellant gases,
various household cleaners, etc.
Cupboard-like Enclosures
Note:
Ventilation requirements as per AS5601.

3.3
Connecting Appliance
Secure heater to the wall using the two mounting brackets
supplied.
3.4
Removal of Front Shell
Remove retaining nut (below gas slide). Swing the casing
to the front and push upwards.
3.5
Water Supply
Pipes of suitable bore according to local conditions and in
compliance with pertinent regulations to be used.
Cold water inlet (right) and hot water outlet (left) are marked
by arrows on the water valve housing.
Use only Gate Valve or Full Flow Ball Valve. Non-Return
Valves MUST NOT BE USED.
Cold water - flush all lines prior to connection.
Make sure water filter is fitted to inlet point of water valve.
Fit inline water strainer where appropriate.
3.6
Gas connection
Size gas supply pipe as per AS5601. Note: inadequate pipe
sizing may void the warranty.
3.7
Flue
Use approved single or twin skin flue in accordance with
AS5601.
3.8
Commissioning
Purge gas piping of air. Trapped air can result in the pilot
burner failing to light within 30-40 seconds. In that case,
turn off the hot water tap and then turn it on again. This
restarts the ignition cycle.
3.9
HDG Functioning
HDG is located in the water circuit, between the water valve
and the heat exchanger. The HDG has a turbine, which
turns with the water flow. This movement is transmitted to
an electric generator, which supplies the electronic box.
The electric voltage supplied by the HDG is a value between
1,1 and 1,7 V DC. With the HDG, the use of batteries is no
longer necessary.

Servicing
4.1
Setting Appliance
All heaters are adjusted before leaving the factory. LPG gas
heaters are adjusted for 2,75 kPa and Natural gas heaters

of gas available at the installation.
4.2
Gas adjustments
Gas burner pressure adjustment for maximum
output
1.
Turn off gas supply.
2.
Loosen sealing screw D (diagram 5) and connect U
tube manometer.
3.
Turn on gas supply and start up appliance in accordance
with operating instructions. Fully open a hot water tap.
4.
Check that burner pressure is as stated on the rating
label.
5.
If other than specified test inlet pressure. Turn off gas
supply, remove manometer, tighten sealing screw, turn
on gas supply and test for leaks.
