Lennox 93M28 Flue Assembly
The Lennox 93M28 Flue Assembly is a critical OEM replacement component designed for high-efficiency gas furnaces to ensure the safe and effective expulsion of combustion byproducts. As a genuine Lennox repair part, this flue tee exhaust assembly is specifically engineered to handle the thermal demands and corrosive nature of flue gases in condensing systems. It maintains precise furnace venting system integrity, preventing the hazardous accumulation of carbon monoxide within the structure. This assembly features a durable 17.75-inch construction, optimized for a precise fit with Lennox G51MP and G61MP series furnaces. Utilizing an authentic 93M28 exhaust tee ensures that the pressure switch readings remain within factory specifications, avoiding nuisance trips and ensuring consistent ignition cycles. For technicians performing maintenance or emergency repairs, this condensating furnace flue part provides a direct drop-in solution to replace degraded or cracked original housings, restoring the unit to peak operational safety and AHRI-rated efficiency without the need for field modifications.
Key Benefits:
- Direct OEM Compatibility: Engineered as a drop-in replacement for Lennox 93M28, 61M36, LB-100741A, and LB-74816A, ensuring seamless alignment with existing vent piping.
- Enhanced Safety Standards: Critical for the proper venting of combustion gases, maintaining a leak-free seal to protect against carbon monoxide infiltration.
- Optimized Furnace Airflow: Precision-molded flue tee assembly reduces backpressure, supporting stable inducer motor performance and overall system efficiency.
- High-Grade Durability: Constructed from heat-resistant materials designed to withstand the acidic condensate typical in high-efficiency condensing gas furnaces.
Common Questions:
Which Lennox furnace models are compatible with the 93M28 flue assembly?
This assembly is primarily designed for Lennox G51MP, G61MP, and G61MPV series furnaces. It also serves as a cross-reference for various Allied, Armstrong, and Ducane models using the same heat exchanger platform.
Can this flue assembly be used in both vertical and horizontal venting configurations?
Yes, the 93M28 flue assembly is designed to facilitate the transition between the furnace collector box and the external vent termination in multiple orientations, provided standard HVAC venting codes are followed.
Why is it important to use a genuine Lennox 93M28 part instead of a generic alternative?
OEM components like the 93M28 are calibrated for specific static pressure requirements. Using a genuine Lennox replacement part ensures the pressure switch detects the correct vent vacuum, preventing safety shut-offs and irregular burner operation.
