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
MHP-135-KFA 5.0 PSI
MHP-190-KFA 7.5 PSI
MHP-215-KFA 9.0 PSI
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
1-K kerosene to loosen any dirt particles.
