Every three years (or when ignition problems occur)
In addition to the annual maintenance,
•
Remove the spark probes and check them for damage and deposits. They should not be
darker than a light gray or have an excessively rounded tip. If the spark probes are
damaged or excessively rounded, they should be replaced. If the spark probe has deposits
then carefully remove them with a damp rag or abrasive plastic pad. Illustration 3 below
shows the original condition of the spark probe as a reference. When you reinstall the
spark probe always use a high
temperature antiseize compound rated for
at least 1200F on the threads of the
mounting screw and, if necessary, seal
the joint between the spark probe and the
combustion chamber with a high
temperature exhaust or furnace cement
rated to at least 900F. Be careful to avoid
getting any cement on the mounting
screw to allow future removal of the
sparker.
