3. For Direct Spark Ignition (DSI) System Models Manufactured With ADC Module Part No. 880815
a. Upon completing installation of the
replacement DSI module, reestablish power
to the dryer.
b. Starting the drying cycle.
c. The ignition DSI modules light emitting diode
(L.E.D.) indicator will light red for up to
approximately 1.5-seconds (prepurge time).
d. The modules indicator light will then turn
green. The gas valve will be energized and
the ignitor probe will spark for approximately
8-seconds. The burner flame should now
be established.
e. With the burner flame on, remove the flame
sensor wire from the FS terminal of the DSI
module.
f. The burner flame must shut off and the ignition
module must lockout with the DSI modules
indicator light red.
g. Stop the drying cycle, with the flame sensor wire still removed, restart the drying cycle.
h. The ignition module must proceed through the prepurge, with the indicator light red, the ignition trial
time of approximately 8-seconds, with the indicator light green, and then proceed to lockout with the
indicator light red.
i. Functional check of the DSI module is complete.
1) Replace the flame sensor wire from the FS terminal to the DSI module.
