Air Adjustment

The oil burner on this machine is preset for operation at
altitudes below 500 feet. If operated at higher altitudes,
it may be necessary to adjust the air band setting.
Adjust air band for a #1 or #2 smoke spot on the
Bacharach scale. If a smoky or eye-burning exhaust is
being emitted from the stack, two things should be
checked. First, check the air adjustment on the burner.
An oily, smoky fire indicates a lack of air and the air
band should be moved to allow the air to flow through
the burner. Sharp eye-burning fumes indicate too much
air flowing through the combustion chamber. The air
band should be readjusted to allow less air to flow
through the burner.
To adjust, start the machine and turn burner ON.
Loosen two locking screws found in the air shutter
openings (see illustration) and close air shutter until
black smoke appears from burner exhaust vent. Note
air band position. 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.
