Description
The York S1-02920404000 Crossover Tube carries fuel gas between adjacent burner assembly ports to support ignition across the burner section. Installed in HVAC systems heating equipment, it aligns directly with burner openings to channel a portion of the gas mixture during the ignition sequence. The tube transfers gas to ignite subsequent burners from the main pilot flame, establishing a continuous flame pattern across the burner grid. Consistent gas transfer through the tube allows uniform burner firing, complete heat exchanger coverage, and stable overall heating operation throughout repeated firing cycles.
