air adjustment
The oil burner on this machine is preset for operation at
altitudes below 1000 ft. 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 fuel to be certain that kerosene or No.
1 home heating fuel is being used.
Next, check the air adjustment on the burner. An oily,
black, 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 white fumes indicate
too much air flowing through the combustion chamber.
The air band should be moved to allow less air to flow
through the burner.
To adjust: start machine and turn burner ON. Loosen
the two locking screws found on the air band openings
(refer to illustrations) and close air band until black
smoke appears from burner exhaust vent. Note air
band position. Next, 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 screws.
