Kromschroder Spark ignition electrode 74462401

This spark ignition electrode from Kromschroder fits the ZSI-300/50 pilot burner and other burners of the ZSI series. It measures 300 mm in length and uses a special heat-resistant alloy body, providing high heat resistance and excellent corrosion resistance. Its precise geometry supports simple and quick installation. The electrode produces the spark for ignition and delivers fast and stable ignition. The part is manufactured to meet European safety standards.

Parts of this type are selected by electrode length, bend angle, insulator diameter, spark gap, mounting flange profile, and the burner series they were shaped for. Before ordering, confirm that the replacement matches the required physical fit and insertion depth into the combustion head. Inspect the old part for signs of overheating or damage, and cross-check the burner or pilot burner documentation rather than relying only on the part number printed on the old electrode.

Typical failure modes include a worn or eroded tip, a cracked ceramic insulator, and carbon buildup that shorts the spark or the flame signal. A drifting gap can lengthen ignition time or prevent flame establishment. The burner may fail to ignite, ignite late, or lock out after losing the flame signal. Check the electrode gap, insulator condition, and tip wear, and clean off carbon before re-testing.
