Diesel Burner - Electric Eye Inspection
The diesel burner is equipped with an electronic eye which detects the pres-
ence of a flame. If the eye does not detect a flame after ignition, it will shut
down the burner.
Periodically this eye will get covered
with soot or dirt from the burner. If your
burner lights and then shuts down im-
mediately, you can normally expect the
problem to be a dirty electric eye. To
clean the eye, simply loosen the two
retaining clip screws (A) and rotate the
clips which hold the hinged spark box
(B) to the burner. Gently wipe the eye
(C) with a soft cloth and reattach the
spark box.
After cleaning the eye, if the burner will not stay ignited after initial firing,
check fuse located inside the primary control box. You can open the box by
loosening the two screws (D) and removing the box.
Burner Motor Brush Inspection
Due to the high current draw of the burner motor, it is advised to inspect the
brushes for excessive wear every 100 hours of operation. If the brushes are
worn out completely it will stop the motor and typically damage or destroy the
ignition transformer assembly.
The brushes can be inspected and installed in a matter of minutes as follows:
1)
Remove the brush caps (A) with a standard straight slot screw driver.
2)
Remove the brushes (B) and inspect. If there is less than 1/8" of brush
remaining, replace it imme-
diately. If not, reinstall exist-
ing brush.
3)
Be sure the radius (C) of the
brush follows the curvature
of the motor as shown be-
low.
4)
When the brushes are worn
close to 1/8", check fre-
quently to avoid failure.
