Giersch Electrode 47-90-26037

The Giersch Electrode 47-90-26037 is an ignition electrode set (left and right) for Giersch GU55, GU100, and GU200 burners. Each electrode has a length of 162 mm and a diameter of 3 mm, with ceramic insulation and plugs for high-voltage cables. The body is made of heat-resistant corrosion-resistant alloys, and the insulation is ceramic. This set is designed for ignition in liquid fuel burners, including those operating on waste oil.

When selecting electrodes of this type, confirm that the tip shape, overall reach, and insulator size match the existing part. The spark gap and mounting configuration must be compatible with the burner series. Measure the electrode length, diameter, and insulation dimensions before ordering. Ensure the connection type matches the high-voltage cables.

Common failures include erosion of the spark tip, cracked or sooted ceramic, and a drifting gap that lengthens ignition time. On burners with a pilot flame, unreliable electrode performance can cause intermittent flame signal or delayed ignition. Check for visible damage and measure the spark gap if ignition issues occur.
