PILOT BURNER MALFUNCTION
Pilot will not ignite; no evidence of gas at the pilot burner.
•
Check that the gas valve is open and gas is present at the valve.
•
Check pilot burner adjustment. Adjust the pilot flame to extend above the top of the pilot. Pilot adjust screw is located
beneath cover screw.
•
Remove pilot gas supply line and check for dirt. Blow out if necessary and reinstall.
•
Check pilot burner orifice for dirt.
Pilot burner ignites but will not remain lit when gas cock dial is released.
•
Check that the thermopile lead is firmly into the safety valve.
•
Remove end of thermopile lead from safety valve and clean with fine sandpaper.
•
If thermopile is defective replace it.
•
Check connection of the lead from safety valve to hi-limit, if defective replace it.
•
Pilot flame may be too high or too low. Adjust flame by turning pilot flow adjustment screw.
•
Check the hi-limit wire connection between the safety valve and the thermopile.
•
Check hi-limit safety switch, if defective replace it.
Pilot flame of proper size but unstable. Flame wavers and does not envelope the thermopile.
•
Check for drafts, which might be caused by air conditioning equipment or make-up air apparatus. Turn these OFF and
recheck the pilot.
MAIN BURNER MALFUNCTIONS
Main burner will not come ON; no gas present at main burner.
•
Check that the gas valve is open.
•
Check that pilot is ignited and is operating properly.
•
The combination control may be defective. Replace it if necessary.
Main burner appears small and lazy; fryer is not heating up quickly.
•
Check gas pressure at the pressure tap on the manifold pipe located behind the door panel. Use a standard water type U-
gauge manometer. With the burners in operation, the manifold pressure should be 4” WC natural gas and 10” WC on
propane gas. If not, unscrew the cover of the pressure regulator. Use a screwdriver to turn adjusting screw clockwise to
increase gas pressure to burner, counterclockwise to decrease pressure to the burner. Replace cover and plug.
Signs of excessive temperature; frying compound scorches and quickly becomes discolored.
•
Check operating thermostat. May be out of calibration; recalibrate.
