Installation

Install only on an external wall, as close as possible to the most frequently used hot
tap. Use a heat shield (accessory item part number 9 708 061 400) if the unit is to be installed
on a combustible surface. Allow minimum air gap of 10 mm between the flue and the heat
shield, (refer figure 2).

Ensure that the flue terminal is clear of any combustible material, and avoid
installation in a marine environment.

Install the appliance such that the base of the appliance is not more than 1.3 metres
and not less than 0.5 meters from the ground, and allow for easy access to service heater.

Secure heater to wall using two 10g X 5/16 hex head wood screws
Locate head of screw in the key hole of the top mounting bracket.

Pip e Connections

Hot and Cold water ½" male
Natural gas ¾" female
L.P. gas ½" male

A gas cock must be installed in the gas supply line with provision to disconnect the
appliance. Install gate valve or full flow ball valve (fixed mechanism type) in cold water supply.

Refer to Fig. 1 for locations

A non return val ve m ust not be fitted. Example duo valve

We recommend that all hot water pipes be lagged if the runs are long or exposed, and
water-proof lagging should be used on all external hot water pipes. If the water supply
pressure exceeds 80% of the specified maximum, install a pressure limiting valve.
If installing a pressure limiting valve fit a cold expansion valve between the limiting valve and
the appliance. PLV = 500kPa Cold expansion = 700kPa

Refer to AG 601 and AS3500.1 for the relevant pipe size.

NOTE:

Service calls for incorrect pipe sizing will NOT be covered under warranty.

Water Filter

If sludge or foreign matter is or may be present in the water supply, it is recommended
that a suitable filter be incorporated in the water supply line to the heater. All pipes should be
well flushed before connection is made.
A water filter/strainer is installed in the inlet of the brass water valve inside the appliance.

Water Temperature Adjustment

Located inside the water heater, immediately below the gas controls, is a water
temperature selector knob.
To increase the water temperature ( decrease water flow ) turn the knob clockwise. To reduce
water temperature ( increase water flow ) turn the knob anti clockwise.

Refer to rating label located on the bottom right hand corner of the back panel for additional
data.

Freezing

Weather

In areas where the atmospheric temperature may drop below 0°C,
the heater must be drained to prevent damage by expansion of freezing
water. For appliances installed in locations where the temperature falls
below 0° C for brief periods , the installation of an EXOGEL expansion
valve, (part number H 707 060 151), will minimise the possibility of damage
to the appliance.

Hot Water

This water heater MUST NOT be installed in areas where the
temperature remains below 0°C for extended periods.

Conversion and Spare Parts

For spare parts or conversion of the heater to operate on a different gas that for which it was
originally manufactured, please contact your local gas authority, authorised service agent or
the manufacturer
