8.0.2. Excessive Smoke Coming Out of Exhaust Stack
Step Smoke Coming Out of the Exhaust Stack
1 White smoke indicates that there is too much air being forced though the burner. Loosen the
Air Shutter screw and rotate the Air Shutter counter clockwise to reduce air. Refer to
Figure
8.3 Diesel Burner Air Settings , for the proper air settings and diagram.
2 Black smoke indicates that there is not enough air being forced through the burner. First
check the air settings, if more air is required rotate Air Shutter clockwise. Refer to
Figure 8.3
Diesel Burner Air Settings.
3 Refer to Figure 8.3 Diesel Burner Air Settings to locate the following components. Using a
7/16" wrench, remove the copper fuel line nut attached to the nozzle line. Next remove the
locking nut for the nozzle tube. Then loosen the locking tabs on the ignition coil and open the
ignition coil. Remove the nozzle line assembly.
4 Using Figure 8.2 Diesel Burner Electrode Adjustment , make sure the electrodes are in the
correct position. Loosen the clamp holding the electrodes in place so they can be adjusted.
Inspect the porcelain ceramic insulator for any cracks. Also check the tip of each of the
electrodes to make sure they still have a sharp point and are not rounded off.
5 If it has been longer than 500 hours since the last time the burner nozzle was replaced,
Crafco recommends replacing the burner nozzle at this time.
6 Reassemble the burner, using the reverse order in Step 3.
7 Remove the burner box assembly by removing the four (4) 1/2" bolts, flat washer, lock
washer, and nuts holding the burner box onto the trailer.
7a Make sure the insulation inside the burner box is not soaked with diesel fuel.
7b If the insulation is soaked with diesel fuel, you will need to replace the insulation.
7c Reassemble the burner box.

1 Remove cord set from fuel solenoid.
2 Check the ohms between the terminals of fuel solenoid.
3 If the reading is between 15-25 ohms the coil is good.
4 If the reading is outside the above range or the meter indicates an open circuit, replace the
fuel solenoid.
