URNER AIR UTTERAD U T ENT

The efficiency of the burner depends on a delicatebalance between the air supply and volume of gas.Whenever this balance is disturbed, poor operatingcharacteristics and excessive gas consumption mayoccur. An air shutter on the front of the burner controlsthe gas mixer balance. A yellow streaming flame onthe burner is an indication of insufficient primary air.

To correct this condition, loosen the shutter screw androtate the air shutter open until the flame begins to liftfrom the burner, then close the shutter slightly andtighten the shutter screw. A proper flame should beblue in color, well-defined and seated on the burnerport. A white-blue flame is a result of excessiveprimary air.

NOTE The factory default air shutter positions arehalf open natural; full open propane.

OThe thermostat-combo valve is self-regulating and thethermostat is internally connected to the valve. When

thermostat dial is set to 350°F and the oven is belowsetpoint, the valve opens to allow gas flow and burnerlights. As the oven temperature rises, the pressurefrom the sensor bulb in the oven increases. Fluid inthe capillary tube expands with the temperatureincrease and presses against a diaphragm in thethermostat. When the oven temperature reachessetpoint, the internal valve closes to stop gas flow toburner.

When the oven temperature decreases belowsetpoint, the pressure is reduced in the capillary whichreduces the force on the diaphragm allowing the valveto open again.

T ER OCOU LE TE T

OThe thermocouple supplies a DC millivolt signal (MV)to the gas safety valve when heated by the pilot flame.The gas safety valve will shut off gas flow to the pilotand main burner in case of a pilot outage. Whenenergized by the thermocouple voltage, the gas safetyvalve is held open to permit gas flow to the pilot andprovide gas for the burner when the oven thermostatcalls for heat. The pilot flame height is controlled byan adjustable needle valve located under a smallcover screw on the gas safety valve.

CIf experiencing pilot outages, perform the following:

Visually check pilot flame for the proper contact onthermocouple and adjust as outlined under PILOTFLAME HEIGHT. If adjustment does not result in apilot flame of proper height, then gas might not beflowing properly to the pilot.

Check for:

• A plugged pilot orifice.

• Kinked or plugged pilot gas tubing.

• Low gas supply pressure.

T CNOTE Tubing connection from the thermocouple tipto gas safety valve is an electrical connection andmust be clean and dry. Do not use any sealingcompound on the threads of thermocouple nut.


Page 27 of 33 F45471 (0913)

Do not overtighten the thermocouple nutor the insulator could be crushed, shorting thethermocouple. Finger tighten the nut plus 1/4 turn witha wrench only.

If pilot flame is correct and there are no excessive airdrafts in the room, then problem is either thethermocouple output voltage or the gas safety valve.

Visually check the thermocouple tip (hot end) and tubelead for:

• Loose thermocouple connection (electrical) atthe safety valve.

• Corrosion or debris on the threaded connector orthermocouple tip causing a poor electricalconnection.

• Kinks or pinches that might cause a shortbetween the tube and the wire inside.

If thermocouple is loose, tighten mounting nut asdescribed above in NOTICE. If thermocoupleconnection shows signs of corrosion or debris thatcannot be cleaned; or damage as described, replaceit and check pilot operation as outlined under PILOTFLAME HEIGHT.

T TCheck the thermocouple output voltage (DC millivolts)with a VOM as outlined in the steps below.

• If thermocouple adaptor (see Tools) is available,check closed circuit voltage as outlined in the testprocedure.

• If thermocouple adaptor is not available, checkopen circuit voltage as outlined in the testprocedure.

• If a VOM is not available, replace thethermocouple with a new one as outlined underSTANDARD OVEN PILOT ASSEMBLY ANDTHERMOCOUPLE or CONVECTION OVENPILOT ASSEMBLY AND THERMOCOUPLE orand check operation GRIDDLE PILOTASSEMBLY AND THERMOCOUPLE.
