Lennox 16U11 Collector Box Replacement Kit Overview
The Lennox 16U11 Collector Box Replacement Kit is an OEM-quality solution designed to restore the collector box assembly on compatible Lennox furnaces. The collector box plays a critical role in the furnace’s venting system, channeling flue gases from the heat exchanger to the draft inducer — making proper fit and function essential for safe, efficient operation.
Why Replace the Collector Box?
Over time, collector boxes can crack, warp, or develop leaks due to thermal cycling and condensate exposure. A compromised collector box can result in flue gas spillage, pressure switch faults, and reduced heating efficiency. Replacing it with a genuine Lennox kit ensures the system returns to factory specifications.
