Why Replace Your Collector Box Gasket?
Over time, gaskets can deteriorate due to repeated thermal cycling, exposure to combustion byproducts, and general wear. A failed collector box gasket may result in flue gas leaks, pressure switch faults, or reduced heating efficiency. Replacing it with the correct OEM part restores proper system function and helps ensure safe operation.
