Lennox 58W08 Header Box
The Lennox 58W08 is a critical OEM replacement part designed specifically for the secondary heat exchanger assembly in high-efficiency furnaces. This plastic header box—often referred to as a collector box or cold end header box—serves as the moisture-collecting transition point between the secondary heat exchanger coils and the condensate drain system. Engineered with high-grade, corrosion-resistant polyethylene construction, it is built to withstand the acidic nature of furnace condensate, ensuring long-term structural integrity within the HVAC vestibule panel. For contractors performing a secondary heat exchanger repair, this component is essential for maintaining proper airflow distribution and preventing leaks that can lead to pressure switch trips or internal corrosion. The Lennox 58W08 features a lightweight, one-piece construction with a 1-inch depth for optimal clearance and a top flange for secure mounting, making it a direct-fit solution for compatible Lennox residential heating units.
Key Benefits- OEM Precision: Guaranteed direct-fit compatibility with Lennox furnaces, eliminating the need for field modifications.
- Corrosion Resistance: Heavy-duty plastic header box design resists the corrosive effects of flue gas condensate.
- Enhanced Efficiency: Restores the airtight seal at the heat exchanger junction, maintaining system static pressure.
- Simplified Installation: Features locking handles and pre-molded mounting points to reduce labor time for HVAC technicians.
What is the function of the Lennox 58W08 header box?
This part acts as a manifold at the "cold end" of the secondary heat exchanger, collecting condensed water vapor and directing it into the drain lines while maintaining the combustion air seal.
Why is my furnace header box leaking?
Over time, constant exposure to acidic condensate or thermal stress can cause cracks in the polyethylene plastic or failure of the mounting gasket. Replacing a damaged Lennox 58W08 prevents water from damaging the inducer motor or furnace cabinet.
Is this part compatible with my Lennox furnace?
The Lennox 58W08 is used in various 90%+ AFUE models. Verify the OEM part number and check the vestibule layout to ensure this replacement plastic header box matches your specific unit’s heat exchanger assembly.
