Gas Conversion and Specifications
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.
On completion of the main and pilot burner adjustments, check all gas connections for leakages.
Turn ‘ON’ to ‘Full’ settings all other gas appliances / equipment supplied from the same gas supply line and
verify the operating pressure remains unaffected by the maximum gas supply demand.
NOTE: Insufficient gas supply line capacity, indicated by the operating pressure drop during the
maximum gas supply demand, is NOT ACCEPTABLE
and may invalidate the manufacturers
warranty for this appliance.
Turn ‘OFF’ the main burners at the gas control knob. Turn ‘OFF’ the main gas supply.
Gas Type Identification Label
On completion of the gas conversion, replace the gas type identification label located at:-
- The rear of the appliance, above the gas connection.
- Beside the rating plate.
