NOTE:
Periodic inspection to insure that the fuel sole-
noid valve functions properly is recommended. This can
be done by operating the machine and checking to see
that when the spray gun is in the off position, the burner
is not firing.
Fuel Pressure Adjustment
To adjust fuel pressure, turn the adjusting screw clock-
wise to increase, counterclockwise to decrease. Do not
exceed 200 PSI.
NOTE:
When changing fuel pump, a
bypass plug must be installed in return port or fuel pump
will not prime.
Burner Nozzle
Keep tip free of surface deposits by wiping it with a clean,
solvent-saturated cloth, being careful not to plug or en-
large nozzle. For maximum efficiency, replace nozzle
each season.

Air Adjustment
Machines are preset and performance tested at the fac-
tory — elevation 100'. A one-time initial correction for
your location will pay off in economy, performance, and
extended service life. If a smoky or eye-burning exhaust
is being emitted from the stack, two things should be
checked. First, check the fuel to be certain that kero-
sene or No. 1 home heating fuel is being used. Next,
check the air adjustment on the burner.
Air Band Adjustment:
To adjust:
start machine and turn burner ON. Loosen
two locking screws found in the air shutter openings (re-
fer to illustration) and close air shutter until black smoke
appears from burner exhaust vent. Note air band posi-
tion. Next, slowly open the air shutter until white smoke
just starts to appear. Turn air shutter halfway back to the
black smoke position previously noted. Tighten locking
screws.
If the desired position cannot be obtained using only the
air shutter, lock the air shutter in as close a position as
can be obtained, then repeat the above procedure on
the air band setting.
