Maintenance
Burner Nozzle
Keep the tip free of surface deposits by wiping it with a
clean, solvent saturated cloth, being careful not to plug
or enlarge the nozzle. For maximum efficiency, replace
the nozzle each season.
Burner Air Adjustment
The oil burner on this machine is preset for operation at
altitudes below 1000 feet. If operated at higher alti-
tudes, 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 diesel fuels specified to (ASTM D975) grade #1 or
#2 is being used. Next, 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.
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 Exploded View page. It is recom-
mended that the oil burner be serviced yearly or as
needed. Contact your local service center.
Wayne Burner Air Adjustment
To adjust, start the machine and turn burner ON.
Loosen locking screw 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.
