Lochinvar & A.O. Smith 100278095 Gasket Set

Lochinvar & A.O. Smith 100278095 Gasket Set

Maintaining a combustion seal is critical for high-efficiency hydronic systems. The Lochinvar & A.O. Smith 100278095 Gasket Set is a comprehensive OEM solution designed to restore the airtight integrity of your burner assembly. This kit is the direct replacement for 100146371, as well as obsolete part numbers GKT20050 and GKT20050K. Specifically engineered for Lochinvar Knight wall-mount boilers, it includes the essential components for the burner heat exchanger and the lower sight glass. Precision-cut for high-temperature resilience, these OEM boiler gaskets ensure that flue gases are contained and combustion remains stable. Using the correct boiler maintenance kit is vital for preventing CO leakage and maintaining strict thermal efficiency in commercial and residential heating applications. When you pull the burner for a heat exchanger cleaning, replacing these seals with the 100278095 replacement gasket is standard protocol to avoid nuisance lockouts and dangerous exhaust recirculation.

Key Benefits
  • Ensures a gas-tight seal between the burner plate and heat exchanger to maximize combustion safety.
  • Includes a dedicated gasket for the lower sight glass for clear and safe flame monitoring.
  • Directly replaces legacy part 100146371, ensuring a perfect fit without field modifications.
  • Engineered specifically for Knight series models including WH399, WHB399N, and WHN400.
  • Prevents thermal degradation of external components by containing radiant heat within the combustion chamber.
Common Questions
  • Which boiler models are compatible with this gasket set? This kit is specifically sized for larger Knight units, primarily the WH399, WHB399, and WHN400 series. Always verify your specific serial number for exact fitment.
  • Is the blower gasket included in the 100278095? This set focuses on the burner-to-heat exchanger interface and the sight glass. For a complete teardown, check the manufacturer's parts list for the separate fan/blower gasket if required.
  • Can I reuse the old gaskets if they look intact? No. High-efficiency boiler gaskets are often compressed upon installation. Reusing them increases the risk of exhaust leaks and improper air-to-gas ratios.
