Description
The Lennox 17F08 Collector Box Cold End Header is a genuine OEM replacement component engineered specifically for compatible Lennox furnace systems. Designed to seal and direct flue gases at the cold end of the heat exchanger, this collector box header plays a critical role in maintaining proper combustion airflow, system efficiency, and safe venting operation.
Product Overview
The cold end header serves as the termination point for the heat exchanger flue passages, collecting exhaust gases and channeling them toward the inducer or venting system. A damaged or deteriorated collector box can lead to flue gas leaks, pressure switch faults, and reduced heating efficiency — making timely replacement essential for safe system operation.

Why Replace the Collector Box Cold End Header?
Over time, the collector box cold end header can crack, warp, or develop leaks due to repeated thermal expansion and contraction, condensate exposure, or physical damage. Symptoms of a failing header include nuisance pressure switch trips, visible cracks or soot deposits, and reduced heating performance. Replacing with a genuine Lennox OEM part ensures a proper seal and long-term reliability.
