De Dietrich 83858935 Brûleur FURIGAS 8 sections

This is a De Dietrich FURIGAS burner of 8 sections, catalogue article 169.205.003, listed under boiler housing parts. Such burners are integral to the appliance housing: they carry the combustion components and seal the chamber. Selection is by exact boiler model and mounting position, not by a generic performance rating. When replacing a burner of this class, confirm that the flange pattern, blast tube length and section geometry match the original assembly. The sections in a burner of this type define the combustion head length and air/fuel mixing path, so any deviation from the factory dimensions can affect flame shape and heat transfer. Because housing parts are model-specific, always verify the appliance serial number or technical data plate before ordering. The burner itself does not include control components or ignition electrodes; those are supplied separately and must be compatible with the burner control system. For installation, follow the manufacturer’s manual to ensure correct alignment and sealing of the combustion chamber.
