Lennox 17F45 Collector Box Replacement Kit

The Lennox 17F45 Collector Box Replacement Kit is an OEM-quality replacement designed to restore the integrity of the collector box assembly on compatible Lennox furnaces. The collector box plays a critical role in the furnace’s venting system — it collects flue gases from the heat exchanger and channels them into the inducer assembly for proper exhaust. A damaged or deteriorated collector box can lead to flue gas leaks, pressure switch faults, and reduced system efficiency, making timely replacement essential.

Application

This replacement kit is intended for use on compatible Lennox furnace models. Always verify compatibility with your specific furnace model number before installation. Refer to the Lennox product documentation or contact your Lennox distributor for model applicability details.

Why Replace the Collector Box?

Over time, collector boxes can crack, warp, or develop failed gaskets due to thermal cycling and condensate exposure. Symptoms of a failing collector box include pressure switch lockouts, visible cracks or deterioration around the inducer mount, and unusual furnace odors. Replacing the collector box with a genuine Lennox kit ensures a proper seal and restores safe, reliable furnace performance.
