Burner Air Adjustment:
The oil bur ner 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 band setting. Adjust the air band for a #1
or #2 smoke spot on the Bacharach scale.
To adjust, start machine and turn burner ON (refer to

slowly open the air band until white smoke just starts to
appear. Turn air band halfway back to the black smoke
position previously noted. Tighten locking screw.
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.
