Electrodo de ionización De Dietrich 300009732

The De Dietrich 300009732 is an ionisation electrode. In a gas burner, the ionisation electrode performs flame proving: it conducts a small rectified current through the flame, which the burner control detects as a confirmation that the burner has lit. This part sits in the flame zone, often near the pilot burner or main burner. Unlike ignition electrodes, which generate a spark, the ionisation electrode only senses the flame and must remain in the flame for the burner to stay on. Parts of this type are consumable because they are exposed to the combustion flame and heat. Typical signs of wear include a cracked ceramic insulator, a eroded or bent tip, or a sooted surface that prevents the rectified current from passing. When replacing an ionisation electrode, the key selection parameters are the overall length of the electrode, the bend angle of the rod, the diameter of the ceramic insulator, the gap between the tip and the burner metal, and the shape of the mounting flange or bracket. The electrode must match the burner series it was originally designed for, as the flame path and mounting position vary between models. This article is listed under the Ionization & ignition electrodes category. The manufacturer code is 300009732, also referenced as 336.946.046. No further technical specifications are provided in the source data. To ensure correct replacement, confirm the electrode geometry against the original part removed from the appliance. Use the type-specific selection criteria above to identify the correct part from a catalogue or supplier listing.
