2. Remove the igniter from the heater. Clean the ignitor
rod with steel wool or emery cloth.
3. The rod and its insulating ceramic body must be rigid
within its mounting bracket. If either are capable of
movement, the igniter will not be properly positioned to
the combustion cone. The igniter must then be
replaced.
Adjusting Ignitor Gap
Gap may need to be adjusted if spark is weak or non-existent
after the ignitor has been either cleaned or replaced. Refer to
the following instructions.
a. Ensure the three burner plate nuts are snuggly
tightened. See Fig 14.
b. To properly check gap, insert gapping tool part # 23967
at opening between inner and outer combustion cone
tips. Position the thickest section of tool between ignitor
tip and inner cone. Adjust gap if needed. See Fig. 15,
shown without outer cone.
Fig. 15
c. If necessary, adjust the gap:
-- loosen igniter mounting screws.
-- reposition the igniter until the gap is
within the proper tolerances.
d. Tighten the igniter mounting screws, and remove gauge.
