Installation Requirements
Water Heater Support:
The water heater must be installed on a
flat, solid, non-combustible supporting
surface. The weight of the water heater
should not cause deformation to any
part of the building structure.
It is recommended that a plinth is
installed under the water heater.
The water heater must be installed
plumb and level.
The water heater must also be secured
to a durable structure using the wall
brackets supplied loose with the water
heater. Note the gas or water pipework
must not be used to support the water
heater.
The wall brackets are designed to be
installed on each side of the water
heater with the long leg against the side
of the water heater and the short leg
against the wall. The brackets should
be located near the top of the water
heater, approximately in line with the
Outlet and Relief Valve sockets. Note
once installed, the brackets should not
obscure any labels on the water heater.
The brackets should be fixed to the wall
with suitable fasteners and fixed to the
water heater with the self drilling screws
provided.
Water Supply:
This water heater has been
manufactured to suit the water
conditions of most Australian
metropolitan supplies.
Please note certain water supplies can
have a detrimental effect on the water
heater and its life expectancy. If you are
unsure about the water supply you can
obtain information from the local water
supply authority.
The water heater is designed for use in
areas where the Total Dissolved Solids
(TDS) content of the water supply is
less than 2500 mg/L. The Tank Failure
Warranty does not apply in areas where
the TDS exceeds 2500 mg/L.
In areas where the TDS exceeds
600mg/L it is possible the magnesium
alloy anode (supplied in standard water
heaters) may become over-reactive.
To alleviate this, the magnesium anode
should be replaced with an aluminium
alloy anode. Aluminium alloy anodes are
available from your local Dux Supplier.
Water can also be very corrosive, the
measure of this is the saturation index.
If the water saturation index is greater
than 0.40, an expansion control valve
should be fitted. Please consult Dux
After Sales and Service for advice if
required.
