De Dietrich 85025579 ignition burner supply pipe

De Dietrich 85025579 ignition burner supply pipe, also listed as 336.835.001. This part belongs to the category of boiler pipes, flanges and connections. Parts of this type serve to convey fuel—typically gas—from the main supply line to the ignition burner assembly within a boiler or burner system. The ignition burner is the component that lights the main flame during the start-up sequence, and its supply pipe must deliver a consistent flow of fuel to the ignition electrode or pilot burner. Such pipes are specific to the appliance they are designed for. Selection of a replacement depends on thread type, thread size, material, and sealing method (flat gasket, O-ring, or taper). The orientation and routing of the pipe are fixed by the geometry of the burner or boiler chassis, so manufacturer-specific connection sets rarely have generic equivalents. When sourcing a pipe of this type, confirm that the fittings, bends, and overall length match the original to avoid interference with other components or incorrect alignment.
