The genuine OEM Lennox 96M82 heat exchanger assembly with vest panel is a factory-matched replacement for your Lennox gas furnace, combining the heat exchanger with its integrated vest panel — the front bulkhead that seals the combustion area and supports the exchanger cells. Together they transfer heat into your home's air while safely isolating flue gases from the blower stream.
Common failure symptoms: Cracked or rusted exchanger cells, flame distortion or roll-out when the blower engages, soot deposits, combustion odors, or a carbon monoxide detector alarm all indicate the assembly needs replacement. A damaged vest panel can also create air leaks that hurt efficiency and flame stability.
Why OEM matters: The 96M82 is dimensioned to bolt directly into your Lennox furnace with the vest panel already sealed to spec, saving installation time and guaranteeing the correct combustion geometry. Non-OEM substitutes risk improper sealing, poor flame patterns, and CO exposure. This factory assembly protects both the safety certification and rated efficiency of your Lennox equipment.
