De Dietrich 83688722 FURIGAS burner

This is a De Dietrich FURIGAS burner, catalogue article 169.205.004, manufacturer codes 83688722 and 169.205.004. It is listed under boiler housing parts. As a burner, it is the component that generates the flame inside the boiler. In a typical system, the burner receives fuel and air, ignites the mixture, and modulates its output to meet heat demand. The burner control (flame safeguard) manages the ignition sequence, flame monitoring, and safety lockout. Parts of this class include the combustion head, fan, gas valve or oil pump, ignition electrodes, and flame sensor. Selection is by boiler model, output range, fuel type, and mounting flange dimensions. When replacing a burner, confirm that the blast tube length and flange pattern match the boiler front plate and that the control box wiring is compatible with the existing controller. Inspect any insulation or gaskets on the burner mounting to avoid heat leakage. No specific technical ratings for this article are stated; refer to the appliance documentation to verify suitability.
