BURNER ADJUSTMENTS

Leak Test
1) Ensure that all control valves are in the OFF position.
2) Turn on the main gas supply valve.
3) Light all pilots.
4) Leak test all valves and fittings using approved methods.
5) Correct any leaks as required and re-check.
6) Shut off all valves and set the control knobs to "OFF" position.
Test Point Pressure
The pressure test point is located on the gas manifold. The gas manifold and
pressure test point is accessed by opening the fryer door. The test point
pressure is shown in the 'Nominal Gas Consumption Table' and is set with the
burners operating at maximum setting.
Pilot Burner Adjustment
Set all pilots so that the flame envelops the tip of the thermocouple by
adjusting the pilot flame adjusting screw on the gas valve - clockwise to
decrease, or anti-clockwise to increase.
Service adjustment should not be necessary unless changing the gas valve or
performing a gas conversion.
Burner Adjustment
The burner orifices are fixed as specified and cannot be adjusted. The
specified gas rate will be achieved if the gas supply pressure and test point
pressure is correct.
A distinct blue flame over the entire port area of the burner will be achieved at
full rate when the air supply is correct and the injector and burner are properly
aligned.
If the flame is yellow and wavy, the cause needs to be established.
WARNING: If you are not competent in performing any service task or require
assistance, please contact your local service agent.
