Lennox 39W98 Trap Assembly

The Lennox 39W98 Trap Assembly is a critical genuine OEM replacement for managing condensate drainage in high-efficiency gas furnaces and residential air handlers. As a direct replacement for LB-96382B and 39W9801, this condensate trap assembly is engineered for a precise fit in Lennox G71MPP series furnaces and compatible Allied, Armstrong, or Ducane units. The Lennox 39W98 maintains the pressure seal required for the induction system, preventing flue gas leakage while ensuring the secondary heat exchanger sheds moisture without backup. Built from corrosion-resistant materials, it handles the acidic nature of 90%+ AFUE condensate to prevent heat exchanger damage and pressure switch trips.

• Matches exact specifications for Lennox G71MPP-36B, G71MPP-36C, and G71MPP-60D models.
• Ensures proper condensate management to avoid water overflow into the burner compartment.
• Restores system efficiency by maintaining the required HVAC drainage air seal.
• Compatible with Lennox furnace units requiring LB-96382B or 39W9801 components.
• Durable housing designed to withstand thermal stress and prevent common vacuum leak codes.

Is the 39W98 compatible with all Lennox furnaces?
No, this specific trap assembly is designed for high-efficiency condensing furnaces like the G71MPP series. Verify your model number or cross-reference LB-96382B for compatibility.

Why is my furnace tripping the pressure switch?
A cracked or clogged condensate trap can prevent proper drainage, leading to water backup in the inducer or pressure switch lines. Replacing a worn 39W98 often resolves drainage-related lockout codes.

Does this include the cleanout cap?
This is the main condensate trap assembly. Technicians should verify if existing clamps or caps are reusable or if a full drainage kit is required.
