Maintenance
Service (Continued):
FAN BLADES:
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 the blades are dry before
re-starting the heater. For fan assembly removal
see Figure 14.
FUEL FILTER:
The fuel filter should be cleaned at least
twice per heating season. Clean the filter by
rinsing it in clean kerosene. Contaminated fuel
could make cleaning the fuel filter necessary
immediately.
NOTE: To remove the filter from models
45 / FF70 turn filter 90º clockwise. To remove
the filter from models 125 / 175 / FF215 turn
filter 90º counter-clockwise. See Figure 15.
SPARK PLUG:
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 0.140” (3.5mm) See Figure 16.
PHOTOCELL:
The photocell should be cleaned using a cotton
swab dipped in alcohol or water at least once
per heating season, or more depending on
conditions. See Figure 17.
