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).
