Removing the Nozzle for Cleaning:
NOTE: Due to swivel fittings on the air and oil lines, it is not necessary to disconnect these lines
when swinging the burner open.
1. Remove the lock-down nut on the mounting flange bolt.
2. Disconnect the burner power cable.
3. Carefully swing the burner open to its maintenance position.
4. Remove the nozzle from the nozzle adapter with a 5/8" socket.

Cleaning the Nozzle:

1. Unscrew the stem from the nozzle head.
2. Spray WD-40 or equivalent through the orifice to thoroughly remove any blockage.
CAUTION: DO NOT damage or deform the nozzle orifice; DO NOT use a torch tip
cleaner or other inappropriate device to clean the orifice. If the blockage is a "tarry"
material or a hard, black material, call your Clean Burn dealer for service.
3. Flush all components with WD-40 to remove oil residues.
4. Reassemble the nozzle components. When tightening the stem, just barely "snug" it down.
DO NOT overtighten.
5. Check the O-ring on the nozzle stem. Replace the O-ring if it is in the least bit cut or
deformed.
6. Lubricate the O-ring on the nozzle stem with a couple of drops of new motor oil, then re-
install the nozzle.
7. Check the electrodes for proper gap and clearances. (Figure A3)
8. Re-install the burner and adjust for optimal performance as described in Section 6.
NOTE: If the nozzle plugs within a few days after cleaning, call your Clean Burn Dealer for
service.
