burner air adjustment: The oil burner on this machine
is preset for operation at altitudes below 3000 feet. If
operated at higher altitudes, it may be necessary to adjust
the air shutter and air band setting. Adjust the air shutter
for a #1 or #2 smoke spot on the Bacharach scale.
To adjust, start machine and turn burner ON (refer
to operation for details). Loosen two locking screws
found in the air shutter openings (refer to Figure 5) and
close air shutter until black smoke appears from burner
exhaust vent. Note air shutter 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.
CAUTION: If white smoke appears from burner
exhaust vent during start-up or operation, discontinue
use and readjust air bands.
NOTE: If a flue is installed, have a professional ser-
viceman adjust your burner for a #1 or #2 smoke spot
on the Bacharach scale.
