De Dietrich 83688595 Barre de brûleurs FURIGAS + vis

This De Dietrich code refers to a burner bar with the fixing screws for an atmospheric gas burner. The burner bar is the component that distributes the gas‑air mixture across the burner ports. In an atmospheric (natural‑draft) burner, the bar sits above the gas injector and below the heat exchanger; the inducer or flue draught draws the combustion air through the burner, and the bar’s geometry defines how the flame front develops. Burner bars of this type are specific to the appliance’s firing rate and chamber design. When replacing, check that the bar is not warped or cracked, that the ports are clear, and that the sealing gasket (where fitted) is sound. The supplied screws should be torqued evenly to avoid distortion. Always verify the gas type and supply pressure before reassembly.
