LIGHTING AND SHUTTING DOWN

GAS IGNITION SYSTEM

1.Turn machine disconnect switch, located on rear of tumbler, to the “on” position.

2.Turn gas shut-off valve, located on rear of tumbler, to the “on” position (gas valve handle should be parallel with gas line).

3.Start tumbler, following operating instructions which accompanied it.

NOTE: Ignition control circuitry will verify airflow switch, located on rear of tumbler, is open before starting cylinder motor. Once cylinder motor is started, air flowing through tumbler will cause airflow switch to close. Tumbler will purge air from tumbler for 18 seconds. Ignition will start by a three second release of gas from gas valve and sparking of ignitor. If ignition does not occur

during first three seconds ignition control will “lockout” causing gas valve to close and a red button on ignition control to illuminate.

To reset ignition system , open access door and press red button on ignition control. Close and lock access door, verify that gas shut-off valve is in the “on” position and return to step three.

4.If tumbler will not start, remove it from service by turning machine disconnect switch, located on rear of tumbler, to the “off” position and turn the gas shut-off valve, located on rear of tumbler, to the “off” position (gas valve handle should be at a right angle to gas line).
