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