(a)To check and/or set the 1/8” (3.175 mm) GAP, use a Direct Spark Ignition (DSI) GAP Feeler Gauge or similar device to determine GAP size. DO NOT USE FEELER TO SET THE GAP, USE IT ONLY TO DETERMINE THE SIZE OF THE GAP. If an adjustment is necessary, bend the ground rod to achieve the correct GAP, then recheck the 1/8” (3.175 mm) GAP with a feeler gauge.

(b)The ALIGNMENT of the Ignitor/Flame-Probe Assembly in relation to the GAP on the ignitor electrode and ground rod must be maintained in as vertical (straight line) a position as possible (refer to the illustration below) otherwise the DSI module will indicate a system malfunction and go into the “LOCKOUT” mode (the light emitting diode [L.E.D.] indicator will BLINK “GREEN” CONTINUOUSLY).

(c)The POSITIONING of the Ignitor/Flame-Probe Assembly is extremely important because it provides the necessary feedback information to the DSI module. The flame- probe electrode must be POSITIONED 1/4” (6.35 mm) minimum into the flame path (refer to the illustration below) and must be POSITIONED 1-inch (2.54 cm) maximum from the burner tube (refer to the illustration below) otherwise the DSI module will indicate a system malfunction and go into the “LOCKOUT” mode (the L.E.D. indicator will BLINK “GREEN” CONTINUOUSLY).

NOTE: To reset the DSI module if it is in the “LOCKOUT” mode, “Burner Control Fault” will display. To clear this fault code press the “CLEAR/STOP” key.
