Kromschroder Ionisation electrode rod ZSI-600/50 74462424

Kromschroder Ionisation electrode rod ZSI-600/50 (SKU 74462424) is a 600 mm electrode made of a special heat-resistant alloy, designed for direct ignition of pilot burners in Kromschroder ZSI series. It operates on the flame rectification principle, sitting in the flame zone to verify burner ignition. The electrode provides a lockout safety feature if no flame signal is detected, ensuring safe operation. It is 100% original and meets German quality standards.

Parts of this type are selected by electrode length, bend, insulator diameter, spark gap, and mounting flange geometry, as well as the burner series they are shaped for. Before ordering, measure the electrode length and compare the mounting configuration to the existing part. Ensure the electrode is positioned correctly relative to the burner head or pilot burner, and that the mounting gasket seals properly. The connection cable and ignition transformer must be in good condition for the flame signal to reach the control.

Common failure modes include an eroded tip, cracked ceramic insulation, sooting that shorts the signal, and a drifting gap that makes ignition unreliable. When these occur, the burner may fail to ignite or lock out due to no flame signal. Check the electrode for damage, clean or replace it if necessary, and verify the ceramic insulation is intact and the gap is correct.
