Électrode Weishaupt 27770514082

This electrode, listed under the Weishaupt brand, belongs to the group of ignition and ionisation electrodes used in gas burners. Ignition electrodes deliver the spark that lights the fuel-air mixture; ionisation electrodes prove the presence of flame by conducting a small rectified current through the ionised gases. Both types live directly in the flame zone and are classed as consumable wear parts. They are typically mounted near the combustion head or on a pilot burner assembly, and they work in conjunction with the ignition transformer and the burner control (flame safeguard). When selecting a replacement electrode of this type, the key parameters are the length and bend of the rod, the diameter and material of the ceramic insulator, the electrode gap, the style of mounting flange, and the specific burner series for which the electrode was originally shaped. Failure to match these geometry details can misplace the spark or the flame-proving path, leading to unreliable ignition or nuisance lockouts. Common failure modes include a worn or eroded tip, cracked ceramic insulation, soot deposits that bridge the gap, and a drifting gap that lengthens ignition time. On burners that use a pilot burner, the pilot carries a small permanent or intermittent flame that both lights the main burner and holds the flame signal; the electrode in that circuit must be inspected regularly. Because the manufacturer codes provided (27770514082, WE2777051408-2) are the reference for ordering, always verify the physical appearance and dimensions against the original part before fitting. No further compatibility or rating data is available for this specific article beyond its name and codes.
