PUMP PRESSURE:
While heater is operating, turn adjusting screw
clockwise to increase, counter-clockwise to
decrease pressure (see Figure 11). Correct pump
pressure is as follows:
Model Number
Pump Pressure
MHP-135-KFA
5.5 PSI (0.38 BAR)
MHP-190-KFA
8.5 PSI (0.59 BAR)
MHP-215-KFA
9.0 PSI (0.62 BAR)
Tolerance ± 10%
NOZZLES:
Nozzles should be cleaned or replaced at
least once per heating season (see Figure 12).
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.
