MAINTENANCE & SERVICE
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.
Air Adjustment
The oil burner on this machine is preset for operation
at altitudes below 1000 feet. If operated at higher
altitudes, it may be necessary to adjust the air band
setting. Adjust air band for #1 or # 2 smoke spot on
the Bacharach scale. A one-time initial correction for
your location will pay off in economy, performance,
and extended service life. 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.
Adjustment
To adjust: start machine and turn burner ON. Loosen
two locking screws found in the air shutter openings
(refer to 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.
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.
Coil Removal
Coil removal, because of freeze breakage or to clean
soot from it, can be done quickly and easily.
1. Disconnect hose from pump to inlet side
of the coil.
2. Carefully disconnect the thermostat sensor making
sure you do not crimp the capillary tube.
3. Remove burner assembly from combustion
chamber.
4. Remove the 3-3/8" bolts from each side of coil and
tank assembly (these bolts are used to fasten tank

5. Remove fittings connected to the 1/2" pipe nipples
from inlet and discharge sides of coil.
6. Remove top tank wrap, bend back insulation tabs
and fold back blanket.
7. R e m o v e b o l t s t h a t h o l d d o w n c o i l t o
