De Dietrich 83758549, rura zasilająca palnik pilotowy, odcinki 3

This is a pilot burner supply pipe, that is, the gas line between the gas valve and the pilot burner. On burners that use a separate pilot flame for ignition and flame supervision, this pipe delivers gas to the pilot injector. The pipe is supplied in three sections, which allows the installer to adjust its length and routing to match the physical layout of the burner. When replacing a pilot supply pipe, check that the end fittings match the gas valve outlet and the pilot burner inlet, both in thread type and size. Also confirm that the pipe is long enough to reach without straining the connections, and that it clears the combustion head and any moving parts on the burner. A damaged or blocked pilot supply pipe will starve the pilot burner and prevent the main burner from lighting.
