ABOUT YOUR WATER HEATER
WATER HEATER APPLICATION
This water heater is designed for use in a single family domestic dwelling for the
purpose of heating potable water. Its use in an application other than this may
shorten its life.
MODEL TYPE
The Aquamax water heater model you have
chosen is suitable for outdoor installation only.
The model is a G135VE series 4 star gas water
heater.
Water is stored in a vitreous enamel lined steel
cylinder and heated by a gas burner located
under the cylinder. The heat produced by the
burner is transferred to the water through the
base of the cylinder and through the wall of a
flue pipe which passes through the centre of
the cylinder. A flue baffle in this flue ensures
the efficiency of the water heater is correct. The
gas supply to the burner is controlled by the
thermostat so the water is heated to a constant
temperature.
Automatic safety controls are fitted to the water
heater to provide safe and efficient operation.
HOW HOT SHOULD THE WATER BE?
The water heater features a user adjustable
thermostat, which allows you to personally
choose the most suitable temperature for your
hot water needs. Refer to “Temperature
Adjustment” on page 5.
To meet the requirements of the National
Plumbing Standard the temperature of the
stored water must not be below 60°C.
Note: AS 3498 requires that a water heater provides the means to inhibit the
growth of Legionella bacteria in potable water. This water heater can satisfy this
AS 3498 requirement provided it is operating and the thermostat setting is 60°C
or higher, including when it is used as an in-series booster water heater for a
solar water heater.

ABOUT YOUR WATER HEATER
HOTTER WATER INCREASES THE RISK OF SCALD INJURY
This water heater can deliver water at temperatures which can cause scalding.
Check the water temperature before use, such as when entering a shower or
filling a bath or basin, to ensure it is suitable for the application and will not cause
scald injury.
We recommend and it may also be required by regulations that an approved
temperature limiting device be fitted into the hot water pipe work to the bathroom
and ensuite when this water heater is installed. This will keep the water
temperature below 50°C at the bathroom and ensuite. The risk of scald injury will
be reduced and still allow hotter water to the kitchen and laundry.
TEMPERATURE ADJUSTMENT
The temperature adjusting dial is on the gas
valve, located behind the access cover on
the lower front of the water heater. A setting
of ‘5’ will normally maintain the water
temperature at about 60°C. Each number
represents a temperature difference of
approximately 6°C.
To increase the water temperature to 66°C
or 73°C, turn the gas control knob
anticlockwise to a setting of ‘6’ or ‘7’
respectively. Refer to “Hotter Water
Increases the Risk of Scald Injury” on
page 5.
PIEZO IGNITION
The “Piezo” push button igniter makes
lighting the pilot flame of your water heater
very easy. Simply follow the instructions on
the label attached to the back of the access
door. There is no need for matches to light
the water heater.
PILOT IGNITER
A permanent pilot flame burns to ignite the
main burner automatically. Heat from the
pilot is absorbed by the water.

REGULAR CARE
MINOR SIX MONTH MAINTENANCE
It is recommended minor maintenance be performed every six months by the
dwelling occupant.
The minor maintenance includes:
Operate the easing lever on the temperature pressure relief valve. It is very
important you raise and lower the lever gently. Refer to “Temperature
Pressure Relief Valve” on page 12.
Warning: Exercise care to avoid any splashing of water, as water
discharged from the drain line will be hot. Stand clear of the drain line’s point
of discharge when operating the valve’s lever.
Operate the easing lever on the expansion control valve (if fitted). It is very
important you raise and lower the lever gently. Refer to “Expansion Control
Valve” on page 11.
Check the drain line from the safe tray (if one is installed) is not blocked.
EXPANSION CONTROL VALVE
In many areas, including Queensland, South Australia, Western Australia and
scaling water areas, it is mandatory an expansion control valve is fitted to the
cold water line to the water heater. The expansion control valve may discharge
a small quantity of water from its drain line during the heating period instead of
the temperature pressure relief valve on the water heater.
Operate the easing lever on the expansion control valve once every six months.
Refer to “Minor Six Month Maintenance” on page 11. It is very important the
lever is raised and lowered gently. If water does not flow freely from the drain
line when the lever is lifted, then the water heater should be checked by

TEMPERATURE PRESSURE RELIEF VALVE
This valve is near the top of the water
heater and is essential for its safe
operation. It is possible for the valve to
release a little water through the drain
line during each heating period. This
occurs as the water is heated and
expands by approximately 1/50 of its
volume.
Continuous leakage of water from the
valve and its drain line may indicate a
problem with the water heater (refer to
“Temperature Pressure Relief Valve
Running” on page 18).
Warning: Never block the outlet of
this valve or its drain line for any reason.
Operate the easing lever on the
temperature pressure relief valve once
every six months. Refer to “Minor Six
Month Maintenance” on page 11. It is
very important the lever is raised and
lowered gently.
Warning: Failure to do this may
result in the water heater cylinder
failing.
Warning: Exercise care to avoid
any splashing of water, as water
discharged from the drain line will be
hot. Stand clear of the drain line’s point
of discharge when operating the valve’s
lever.
If water does not flow freely from the drain line when the lever is lifted, then the
water heater must be checked. Phone Aquamax Service to arrange for an
inspection.
The temperature pressure relief valve should be replaced at intervals not
exceeding 5 years, or more frequently in areas where there is a high incidence
of water deposits (refer to “Water Supplies” on page 13).
