Électrode d'allumage De Dietrich 97955319

This is an ignition electrode for a De Dietrich burner or boiler. An ignition electrode delivers a high-voltage spark from the ignition transformer to light the fuel-air mixture during the start sequence. The spark is generated at the electrode tip, and the gap between the tip and a grounded surface (often the burner head or a dedicated pin) must be set correctly for reliable ignition. Parts of this type are selected by their physical dimensions—electrode length, bend, insulator diameter, and the shape of the mounting flange—because the electrode must reach the correct position in the combustion head without touching the burner body. The ceramic insulator must withstand flame temperature and prevent flashover. When replacing an ignition electrode, check for cracks in the ceramic, erosion of the tip, or carbon build-up that can shorten the gap or cause tracking. The electrode works together with the ignition transformer and the burner control. During the ignition phase, the control energises the transformer, which sends a high voltage to the electrode. If the electrode is damaged or the gap is wrong, ignition may fail and the burner will lock out. The part number 97955319 (also listed as 336.946.035) is the De Dietrich reference. Always compare the electrode shape and mounting arrangement with the original before fitting.
