Kromschroder Spark electrode rod 74462403

Kromschroder spark electrode rod 74462403 is a 500 mm long ignition electrode made of a special heat-resistant alloy. It is designed for direct ignition of the pilot burner in Kromschroder ZSI-500/50 burners. This 100% original German part is resistant to soot and offers high heat resistance.

When selecting a replacement electrode of this kind, verify the electrode length, bend, insulator diameter, spark gap, and mounting flange geometry to match the original part. Ensure the electrode extends correctly into the flame zone and that the ceramic insulator is intact. Set the spark gap to the manufacturer's specification, typically the same as the original.

Common failure modes include a worn or eroded tip, cracked ceramic tube, sooting that bridges the gap, or a drifting gap that weakens the spark. These issues can cause unreliable ignition, leading to burner lockouts. Check the electrode for damage and clean or replace it as needed.
