Mark the position of the grounding rod
on the
new spark igniter, using a felt tip marker. This index mark
must end up 180˚ away from the burner surface when the
spark igniter is inserted and tightened. The electrode
should be closest to the burner surface.
Coat the threads of the igniter
with a high-temper-
ature conductive anti-seize compound.
Carefully insert the igniter into GasTrac.
Insert the igniter straight into the threaded fitting. Do not
bend the electrode, and do not allow the spark igniter to
touch the burner surface.
Screw the igniter into the threaded fitting.
Tighten by hand
first. Then use a
socket and ratchet
to tighten the
igniter one turn or
a partial turn until
the index mark on
the igniter is 180˚
away from the
burner surface.
Push the boot and wire onto the spark igniter.
Push until you feel the boot snap into place.
