until black smoke ap pears from burner exhaust vent.
Note air band po si tion. Next, slow ly open the air
shutter until white smoke just starts to appear. Turn
air shutter halfway back to the black smoke position
previously noted. Tight en lock ing 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.

Initial Air Adjustments:

Allow suffi cient air to obtain

a clean burning fl ame by loosening the lock screws
and moving the air shutter and if necessary the bulk

Reduce the air supply until the fl ame tips appear
slight ly smoky, then increase the air just enough to
cause the fl ame tips to appear absolutely clean.

Burner 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 for a #1 or #2

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

CAUTION: If white smoke appears from burner
exhaust vent during start-up or operation,
discontinue use and readjust air bands.

NOTE: If a fl ue is installed, have a professional
serviceman adjust your burner for a #1 or #2

smoke spot on the Bacharach scale.

Removal of Soot and Heating Coil

In the heating process, fuel residue in the form of
soot deposits may develop between the heat ing
coil pipe and block air fl ow which will affect burner
combustion. When soot has been de tect ed on visual
observation, the soot on the coil must be washed off.
Follow these steps to re move the coil.

1. Disconnect hose from pump to inlet side of the coil.

2. Disconnect electrical connection to the ther mo stat.

3. Remove quick coupler from inlet and discharge side

of coil.

4. Re move bur n er as sem bly from combustion

cham ber.

5. Re move the 3-3/8" bolts from each side of coil and

tank as sem bly (these bolts are used to fasten tank
and handles to chassis).

6. Dis con nect 1/2" pipe nipples from inlet and dis charge

side of coil.

7. Re move top tank wrap exposing in su la tion and coil

and fold back in su la tion.
