Chamber Lining Inspection
After each 200 hours of operation, the chamber lining should be inspected. Remove (8)
burner mount securing bolts (A) and pull out burner and mount. Inspect lining (B) for ex-
cessive cracking. Also check the condition of retainer (C). Lining cracks are acceptable as
long as they are not large enough to allow flame to contact the combustion chamber walls.
Burner Nozzle Replacement
During operation, oil is forced through the
burner nozzle at 140 PSI to permit the fuel
to be atomized for easy ignition. The
nozzle orifice has normal wear due to this
high pressure. Due to the high wear, it is
recommended that the nozzle be replaced
at least once per operating season. To
replace the nozzle, remove the burner from
chamber. Remove the two screws which
secure the burner head (A) to the air tube
(B). Carefully insert a 5/8" deep well
socket over the nozzle (C) and turn it
counterclockwise to remove. Be very
careful not to bend the electrodes (D) while
performing this task. When installing the
new nozzle, do not touch the filter portion
(E) of the nozzle. The filter is so fine that
oil from your skin can clog the filter.
