Lennox 25W90 Plate

The Lennox 25W90 Collector Box Plate is a critical replacement component engineered for high-efficiency Lennox G40, G41, G50, G51, and G61 series gas furnaces. This secondary heat exchanger plate acts as the primary interface for managing condensate drainage and flue gas transitions within the condensing furnace collector box assembly. Manufactured with corrosion-resistant materials, the 25W90 provides a precise seal to maintain required static pressure and prevent toxic combustion byproduct leakage into the surrounding blower compartment. When performing a furnace inducer motor replacement or heat exchanger inspection, technicians often identify cracks or gasket failure on the original plate, making this OEM component essential for restoring factory-specified airflow and drainage. This plate ensures the HVAC drainage system functions without backup, protecting the induced draft blower from premature failure caused by moisture accumulation or improper venting pressure.

Technical Specifications & Benefits

  • OEM Compatibility: Exact fit for Lennox 25W90, ensuring seamless integration with existing collector box gaskets.
  • Structural Integrity: Reinforced secondary heat exchanger plate design minimizes thermal warping during high-fire cycles.
  • Pressure Regulation: Facilitates accurate pressure switch readings by maintaining a consistent vacuum seal within the flue assembly.
  • Corrosion Resistance: Engineered to withstand the acidic nature of furnace condensate over extended run times.
  • Contractor Grade: Direct replacement part designed to meet or exceed original equipment performance standards for Lennox HVAC systems.

Common Installation Questions

Is the gasket included with the 25W90 plate?
Standard Lennox collector box plates typically require a separate perimeter gasket or RTV high-temp silicone, depending on the specific furnace model and the revision of the collector box assembly being serviced.

What symptoms indicate a failing collector box plate?
Technicians should look for visible water staining around the inducer housing, localized rust on the furnace floor, or pressure switch lockout codes caused by air leaks through a cracked or warped plate.

Can I use this plate on other furnace brands?
No, the 25W90 is a brand-specific Lennox furnace part. Mounting hole patterns and drainage ports are proprietary to Lennox G series chassis and are not interchangeable with other manufacturers.
