Gas Conversion and Specifications
Main Burner Injectors
1. Unscrew and remove the main burner injectors (12.7 mm
A/F) located in front of main burner venturi openings.
2. Determine the correct injectors for the corresponding gas
from the ‘Gas Specifications Table’ at the end of this
section.
3. Screw in the correct sized injectors. Refer to the ‘Gas
Specifications Table’ at the end of this section.
Pilot Burner Injectors
1. To prevent damage to the 2 piezo ignition electrodes,
unscrew and remove the electrodes from the mounting
brackets.
2. Unscrew the pilot supply tubes from both pilot burners
and remove the pilot injectors.
3. Determine the correct sized pilot injectors for the
corresponding gas from the table below.
4. Fit the correct sized injectors into the pilot burners and
re-connect the gas supply tubes to both pilot burners.
5. Refit the 2 piezo ignition electrodes to the mounting
brackets and tighten hand tight.
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.
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 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. (Refer to Fig 12).
c. Adjust this screw so that the flame impingement on the 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. (Refer to Fig 12).
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.
