IGNITION ELECTRODE
Blades should be cleaned at least once per heating season, depending
on conditions.
Remove all accumulated dust and dirt with a damp cloth, taking care
not to bend any of the fan blades. Be sure fan blades are restarting the
heater.
Nozzles should be cleaned or replaced at least once per heating season.
Contaminated fuel could make this necessary immediately. To clean
dirt from nozzle, blow compressed air through nozzle front. It may be
necessary to soak nozzle in clean 1-K kerosene to help loosen any
particles.
NOTE: Use of diesel may require additional maintenance. Using this
heater without proper maintenance or with contaminated or old fuel may
lead to improper combustion and possible soot production.
Clean and re-gap every 600 hours of operation, or replace as needed.
After removing the Spark Plug, clean the terminals with a wire brush. Re-
gap the terminals to 3.5mm.
