Lennox 32M65 Flue Collar

The Lennox 32M65 Flue Collar is a critical OEM replacement part designed for high-efficiency combustion assembly in residential and commercial Lennox gas furnaces and boilers. This precision-engineered flue collar features an internal diameter (ID) of 2 inches and an overall length (OAL) of 10.148 inches, providing a robust, airtight connection between the furnace's heat exchanger or draft inducer and the exhaust venting system. Fabricated from high-temperature-resistant metal alloys, this vent pipe adapter is built to withstand the rigorous thermal cycling of modern condensed and non-condensed heating equipment. As a veteran-grade HVAC furnace component, it ensures proper flue gas scavenging, preventing carbon monoxide leakage into the mechanical room and ensuring your exhaust venting system remains compliant with local mechanical codes and manufacturer specifications for clearance and airflow efficiency. Rely on this authentic Lennox 32M65 to maintain optimal static pressure within the venting circuit and protect the longevity of the draft inducer motor.

Common Questions:

What are the exact dimensions of the Lennox 32M65 Flue Collar?
This part is specified with a 2-inch inner diameter and a total length of approximately 10.148 inches, making it the standard replacement for various mid-to-high-efficiency Lennox units.

Is this flue collar compatible with other furnace brands?
The 32M65 is a genuine Lennox HVAC part. While it may share dimensions with some Armstrong or AirEase equipment (which fall under the Lennox International umbrella), you must verify the specific model number to ensure a legal and safe vent pipe seal.

When should a technician replace the flue collar?
You should replace the collar if you observe signs of heavy oxidation, pitting, or physical cracking during a heat exchanger inspection, or if the seal to the flue pipe has been compromised by mechanical stress.
