Burner Components
Ignition Electrodes
The diesel burner’s ignition coil produces a high voltage ignition
spark (approximately 8000 volts) across the ignition electrodes,
which ignites the incoming air/fuel mixture.
Cleaning & Maintenance:
1. Polish away any carbon deposits that may have baked
onto the metal tips of the ignition electrodes with a coarse
sponge.
2. If the ignition electrode’s electrical insulator is cracked or
damaged, the ignition electrode must be replaced.
NOTE: In order to perform the following procedures, it is
necessary to detach and reattach the diesel burner head.
Be sure to review the detaching/reattaching procedure
starting on Page 47.
Ignition Electrode Adjustment Procedure:
1. Follow the directions for detaching/reattaching the diesel
burner on Page 47.
2. Using a 10mm socket, lightly loosen the retaining clamp
bolt.
3. Place the electrode adjustment gauge on the fuel nozzle
manifold hex and insert the metal tips of the ignition
electrodes into the appropriate notches of the electrode
adjustment gauge.
4. Using a 10mm socket, tighten the retaining clamp bolt.
5. Remove the electrode adjustment gauge and reattach to
the diesel burner head.

of the electrodes should be perfectly lined up in the notches.
