Lennox 96L77 Heat Exchanger
The Lennox 96L77 Heat Exchanger (Catalog Number 96L77, superseding LB-58087BT) is a critical OEM replacement part engineered for high-efficiency gas furnaces. This 125SS Heat Exchanger assembly is constructed from stainless steel to withstand high-combustion temperatures and prevent premature thermal stress fracturing. Designed for large-scale residential and light commercial Lennox units, it arrives as a robust assembly with a gross weight of 151 lbs. This specific configuration is a 125SS HtExch, No ColBx, BaffBrkt, meaning it includes the baffle bracket but is supplied without the collector box. For contractors performing a furnace heat exchanger replacement, this genuine Lennox HVAC component ensures precise fitment, maintaining the original AFUE rating and combustion safety of the appliance while eliminating the risks associated with universal after-market alternatives.
Key Benefits
- OEM Precision: Direct Lennox 96L77 replacement ensures exact alignment with burners and inducer housings, reducing labor time during HVAC repair.
- High-Grade Construction: The stainless steel heat exchanger design provides superior corrosion resistance against acidic condensate found in high-efficiency systems.
- Updated Performance: As the official successor to the Lennox LB-58087BT, this part incorporates the latest engineering refinements for improved thermal transfer.
- Professional Grade: Built to meet rigorous industrial standards for HVAC professionals and contractors managing critical heating infrastructure.
Common Questions
Is the collector box included with the 96L77?
No, this specific part number is a 125SS HtExch, No ColBx. You must retain the existing collector box or source it separately if the original is cracked or compromised.
Which models are compatible with this heat exchanger?
The Lennox 96L77 is typically found in G-series and high-capacity Lennox furnaces. You should verify compatibility using the 11-digit serial number of the unit to ensure the 125SS configuration matches the cabinet width and BTU output.
Does this assembly include the baffle bracket?
Yes, this unit includes the BaffBrkt (Baffle Bracket) as specified in the technical data, ensuring proper airflow distribution across the heat exchanger cells.
