2. Direct Spark Ignition (DSI) System
a. Upon completing installation of the replacement
Direct Spark Ignition (DSI) module, reestablish power

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 lock out with the DSI module's 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
pre-purge, with the indicator light "red", the ignition
trial time of approximately 8 seconds, with the
indicator light "green", and then proceed to lock out
with the indicator light "red".
i. Functional check of the Direct Spark Ignition (DSI) Module is complete.
