Adjustment
The main burner pressure must be
set at installation in accordance
with that marked on the Data
Plate. Adjust the Gas Control as
required to achieve specified gas
test point pressure. If problems are
encountered in this process contact
the Dux Service Department.
Failure to accurately set the pressure can
result in damage to the water heater, and
automatically cancels the Manufacturer’s
Warranty. This water heater is to be
installed only by an Authorised Person.
The pressure is best checked by
connecting a water manometer or
equivalent to the test point nipple.
The
test point pressure must comply
with the value on the Data Label.
If adjustment is necessary, follow the
instructions below:
1. Remove the securing screw (1) from
the top of the Gas Control and lift
the plastic cover (2) upwards.
2. Locate the regulator adjustment
screw on the lower left hand side of
the Gas Control (3).

screw clockwise to increase, or anti-
clockwise to decrease pressure.
4. Replace the plastic cover and
securing screw.
5. Replace the test point nipple
