Burner 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 for a #1 or #2
smoke spot on the Bacharach scale.
To adjust, start machine and turn burner ON. Loosen
two locking screws found on the air band 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 previously noted position.
Tighten locking screws.
For higher altitudes, the air band opening may need to
be increased; for lower altitude, the .air band may need
to be decreased.
For higher humidity, the air band opening may need to
be increased; for lower relative humidity, the .air band
may need to be decreased.
For higher ambient temperatures the air band opening
may need to be increased; for lower ambient tempera-
tures, the air band opening may need to be decreased.
Adjust to your operating location’s environment as-
needed for best smoke spot and performance
compliant with local, state, and federal regulations.
CAUTION: If white smoke appears from burner
exhaust vent during start-up or operation, discon-
tinue use and readjust air bands.
ATTENTION: Si de la fumée blanche s'échappe de
l'évacuation du brûleur pendant le démarrage ou le
fonctionnement, cesser d'utiliser et réajuster les
bandes d'air.
NOTE: If a flue is installed, have a professional
serviceman adjust your burner for a #1 or #2 smoke
spot on the Bacharach scale.
For additional burner component information, see
Burner Assembly page. It is recommended that the oil
burner be serviced yearly or as needed. Contact your
local service center

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.
