8.8 — Gas Burner Maintenance
8.7.4 — Ignition System
For best results, maintain the proper gap and dimensions for the ignition electrode(s).
Inspect the electrode tip for signs of pitting or combustion deposits and dress as required with a fine file. Inspect
the porcelain insulator (s) for any cracks that might be present. If there are cracks, replace the electrode since
they can cause grounding of the ignition voltage. Since carbon is an electrical conductor, it is necessary to keep
the insulating portion of electrode(s) wiped clean if any carbon is present. Ammonia will aid in removing carbon
or soot.
Check ignition cables for cracks in the insulation. Also see that
all connections between the transformer and the electrodes are
tight. Periodically remove the access plug from the gas pilot
aspirator and clean out any accumulated lint or other foreign
material.

8.8 — Gas Burner Maintenance
The gas burner components should be inspected for evidence of damage due to improperly adjusted combustion.
Combustion adjustments should be checked monthly.
Check periodically for a proper seal between the end of the burner housing and boiler refractory. Any deterioration
of the seal should be corrected, as an improper or poor seal allows air leaks, which can cause overheating or
burning of the burner housing.
Whenever the burner is removed, the diffuser, gas housing and gas spuds should be checked for any deteriora-
tion. Verify that the diffuser skirt conforms to the bore of the burner housing so as to minimize the amount of
combustion air which bypasses the diffuser. Check to see that the diffuser is properly located in reference to the
gas spuds. There should be 1/4” between the edge of the diffuser fins and the gas spuds when the burner is
installed. Check to see that the diffuser fins do not interfere with the gas ports or gas spuds in the burner hous-
ing.
