Kromschroder Ignition electrode rod (spark / ignition electrode) ZKIH L500 74450304

Kromschroder ignition electrode rod (spark / ignition electrode) ZKIH L500, SKU 74450304, is a high-voltage electrode with a length of 500 mm. It operates at an ignition voltage of 5 kV and is designed for use with Kromschroder ZKIH L500 pilot burners. The electrode is heat-resistant and suitable for demanding combustion environments.

When selecting a replacement electrode of this type, match the overall length, bend angle of the tip, diameter and material of the ceramic insulator, spark gap (typically 2-4 mm for gas burners), and mounting flange dimensions to the specific burner series. Ensure the electrode is compatible with the pilot burner model and that the ignition transformer provides the required voltage.

Common failure modes include cracked or sooted ceramic, worn or rounded tips that increase the spark gap, and carbon bridges that short the spark to earth. Symptoms may include failure to ignite, intermittent ignition, or burner lockout. Inspect the electrode for damage and replace it according to the manufacturer's service schedule.
