FULL SIZE GAS CONVECTION OVENS - SERVICE PROCEDURES AND ADJUSTMENTS

VERIFICATION OF SPARK AT

IGNITOR

WARNING: DISCONNECT THE

ELECTRICAL POWER TO THE

MACHINE AND FOLLOW LOCKOUT /

TAGOUT PROCEDURES.

WARNING: SHUT OFF THE GAS BEFORE SERVICING THE UNIT.

1.Remove the bottom front cover as outlined under COVERS AND PANELS in REMOVAL AND REPLACEMENT OF PARTS.

2.Disconnect the high voltage IGNITION CABLE from the spark ignitor.

WARNING: DO NOT HOLD THE WIRE WITH YOUR HANDS FOR THIS TEST. THE MANUAL GAS VALVE MUST BE CLOSED.

3.Clamp the ignition cable in a manner that will position the end of the cable 3/16" from the oven frame (bare metal surface).

NOTE: It is critical that the cable be held 3/16" away from the surface of the oven frame or sparking may not occur even though the sparking circuit is functioning properly.

4.Plug the oven in and set the temperature control to the maximum setting.

5.Turn the power switch ON.

6.Sparking should occur after a 4 second delay, for a duration of 7 seconds then repeat twice after a 15 second purge time. Arching from the ignition cable to the oven frame should be observed.

DOOR SWITCH ADJUSTMENT

WARNING: DISCONNECT THE

ELECTRICAL POWER TO THE

MACHINE AND FOLLOW LOCKOUT /

TAGOUT PROCEDURES.

1.Remove the top front cover as outlined under

COVERS AND PANELS.

2.Door operation:

A.Independent doors - The switch actuator should be operated by the switch lever when the right door is between 1" and 1 1/2" from being closed.

B.Simultaneous doors - The switch actuator should be operated by the switch lever when the right door is 1/2" from being closed.

3.If adjustment is necessary, bend the switch actuator to obtain the proper setting.

4.Install the top front cover.

5.Apply power to the oven and check for proper operation.
