Revision 1/
Gas Controller
NOTE: For Twin Tank Fryers only, the units will be fitted with 2 gas controllers. These controllers
operate independently of each other. The gas regulators and pilot adjustment will need to
be carried out separately for each gas controller.
Main Burner Operating Pressure Adjustment
a. Connect a manometer to the lower test point (Burner Pressure) on the gas control valve located
through the access hole in the control panel.
b. Remove the slotted cap located directly below the main gas control knob on the gas control
valve, this will reveal an operating pressure adjusting screw.
c. Light the main burners and adjust the adjusting screw to obtain the correct burner pressure for
the type of gas being used. Refer to the specification table shown at the end of this section.
d. Refit the slotted cap to the screw adjustment point.
NOTE: For GT46 - twin tank fryer, repeat Items a) to d) to adjust the main burner controlled by the
second gas control valve.
Pilot Burner Flame Adjustment
a. Once the main burner operating pressure
has been set, the pilot burner supply can be
adjusted so that impingement of the pilot
flame on the thermocouple and thermopile
is correct and the main burner pilot flame
ignites the main burners satisfactorily.
b. Adjust the pilot flame size by adjusting the
pilot burner adjusting screw on the lower
right side of the gas control valve, below
the gas control knob.
c. Adjust this screw so that the flame
impingement on the thermopile and
thermocouple is correct and that the flame
of the pilot burner is approximately 1" long
for main burner ignition.
Anti-clockwise rotation of the adjustment
screw will increase the size of the pilot
flame.
NOTE: (For GT46 - twin tank fryer, repeat Items a) to c) to adjust the pilot burner controlled by the
second gas control valve).
On completion of the main and pilot burner adjustments, check all gas connections for leakages and then
turn off the main burners at the gas control knob. Turn off the main gas supply.
