Service (Continued):
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 5.
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 6.
PUMP PRESSURE:
While heater is operating, turn adjusting screw
clockwise to increase, counter-clockwise to
decrease pressure. Correct pump pressure is as
follows:
Model Number Pump Pressure
45-KFA 3.0 PSI (0.21 BAR)
80T-KFA 3.8 PSI (0.26 BAR)
140T-KFA 6.6 PSI (0.41 BAR)
190T-KFA 8.5 PSI (0.59 BAR)
215T-KFA 9.0 PSI (0.62 BAR)
Tolerance ± 10%
NOZZLES:
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 the nozzle in K-1 kerosene to
loosen any dirt particles.
