(a) To check and/or set the 1/8 (3.175 mm) GAP, use a DSI (Direct Spark Ignition) 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 L.E.D. [light
emitting diode] 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 CLEAR/STOP key.
