ACV Electrode bent 537DX006

The ACV Electrode bent 537DX006 is a replacement ionization and ignition electrode for ACV ALFA sprint M/mv burners. It delivers the ignition spark and, once the flame is established, proves its presence by conducting a small rectified current through the flame. This electrode is resistant to soot, which helps maintain performance in combustion environments. It is designed to fit the specific burner head and pilot burner assembly of the ALFA sprint M/mv series.

Parts of this type are selected by matching the electrode's overall length, bend angle, insulator diameter, spark gap setting, and mounting flange pattern to the burner head and pilot burner assembly. Before ordering, measure these dimensions and compare them with the specifications of the existing electrode. Ensure the spark gap is set correctly and the mounting flange aligns with the burner's fixing points.

Typical failures include a worn or sooted tip, a cracked ceramic insulator, and a drifting gap that lengthens ignition time or weakens the flame signal. When these occur, the burner may fail to ignite or may shut down during operation due to a weak flame signal. Check the electrode for visible damage, clean or replace it if sooted, and verify the spark gap. Also inspect the ignition transformer and burner control, as a failing high-voltage supply or degraded flame-sensing circuit can cause repeat electrode damage.
