Operating Instructions
The appliance is not intended for use
by young children or infirm persons
without supervision. Young children
should be supervised to ensure that
they do not play with the appliance.
Warning:
it is essential for the safe
operation of this gas heater that clothing
or any other flammable material should
not be placed against or on top of the
water heater. In addition, do not store
flammable or corrosive materials, such
as dry cleaning fluids, pool chemicals,
etc., in close proximity to the heater.
The use of aerosol sprays in the vicinity
of the heater should be avoided. The
propellant gases used in these devices,
e.g. fly-spray, hair-spray and laundry
aids, can break down in the flames of the
burner and produce corrosive agents.
Caution: If the water heater is left in
an operating condition and unused
for two weeks or more, a quantity of
hydrogen (which is highly flammable)
may accumulate in the top of the water
cylinder. To dissipate this gas safely it is
recommended that a hot tap be turned
on for several minutes at a sink, basin
or bath, but not a dishwasher, clothes
washer or other appliance. During this
procedure there must be no smoking,
open flame or any other electrical
appliance operating nearby. If hydrogen
is discharged through the tap it will
probably make an unusual sound as
with air escaping.
Water Quality
Your Dux water heater has been
manufactured to suit water conditions of
most Australian metropolitan supplies.
Please note that harsh water supplies
can have a detrimental effect on the
water heater and its life expectancy. If
you are unsure about your water quality
you can obtain information from your
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. In areas where the
TDS exceeds 600mg/L the magnesium
alloy anode (supplied in the heater) may
become over reactive. To alleviate this,
the anode should be replaced with an
aluminium alloy anode, available from
your local Dux supplier.
Water can also be very corrosive,
measured by the saturation index. If the
water saturation index is greater than
0.40 an expansion control valve should
be fitted and where the index is greater
than 0.80 the water heater installed
should be a Hard Water Model. Please
consult our Service Department for
advice if required.
