Lochinvar & A.O. Smith 100208085 Burner Gasket

The Lochinvar & A.O. Smith 100208085 Burner Gasket is a critical high-temperature seal engineered for professional-grade HVACR combustion systems. As a direct OEM replacement part, this component ensures a gas-tight interface between the burner and the air manifold, preventing hazardous leaks and maintaining precise combustion efficiency. Fully interchangeable with part numbers GKT2451 and GKT2451K, it is designed to withstand the thermal cycling and high-stress environments typical of Lochinvar Knight boilers and A.O. Smith commercial water heaters. Using high-grade, heat-resistant materials, this burner gasket prevents air bypass, ensuring the flame signal remains stable and the 100208085 burner assembly operates within manufacturer specifications. For field technicians performing annual maintenance or boiler repairs, installing a fresh Lochinvar 100208085 gasket is a standard protocol to avoid ignition failure or CO risks associated with worn seals. Verify your specific model's bolt pattern and gas/air manifold orientation during installation to ensure a positive mechanical seal.

Common Questions

Is the 100208085 compatible with both Lochinvar and A.O. Smith units?
Yes, this burner gasket is a cross-functional OEM part utilized across various residential and commercial heating platforms from both Lochinvar and A.O. Smith, particularly within the Knight and Armor series.

When should a burner gasket be replaced?
Industry best practice for HVACR maintenance requires inspecting the gasket whenever the burner is pulled for cleaning. If the material shows signs of compression set, cracking, or discoloration, it must be replaced to maintain combustion efficiency.

Does this gasket require additional sealants?
No, the Lochinvar 100208085 is designed to provide a dry mechanical seal. Using unapproved petroleum-based sealants can damage the gasket material and compromise the burner system.
