cover panel. See Fig. 8.
f) Remove the governor cap screw on the gas
control valve to gain access to the screw inside
the turret. (See photograph at right)
g) The governor is suitable for both natural and
propane gas.
h) Turn the screw inside the turret clockwise to
increase the pressure, anti-clockwise to reduce
it. Check the burner pressure again after 15
minutes operation, and adjust if necessary.
i) Disconnect the pressure gauge from the test
point. Reseal the test point and test for gas
soundness.
j) Replace governor cap screw, and replace

2.3.3
Checking Performance of Controls
a) Light the unit as described in Paragraph 2.3.1,
above. Check that the controls produce a healthy
spark from the electrode to the earthing post,
and that ignition is smooth and without delay.
b) Turn the thermostat off and then on. Check that
the burners go out when the thermostat is turned
off, and that they reignite smoothly when it is
switched back on. Repeat several times.
c) Fill the pan with unused oil up to the mark in the pan.
WARNING
DO NOT OVERFILL WITH OIL OR FIRE MAY
RESULT!
d) Set the thermostat knob at “10" and allow the oil
to heat up. Immerse a thermometer or
thermocouple 25 mm below the oil surface at the
center of the pan. Check that the temperature
stabilizes at 190ºC, (± 5ºC).
CAUTION
THE TEMPERATURE MUST NOT EXCEED 200ºC
OR THE HIGH LIMIT THERMOSTAT WILL TRIP.
e) If the unit fails to operate as described, the unit
should be serviced by an Engineer.
