Lochinvar & A.O. Smith 100276843 Gasket
For high-performance hydronic and domestic hot water systems, the Lochinvar & A.O. Smith 100276843 Gasket is a critical OEM component designed to maintain the integrity of the 2 burner assembly interface. As a veteran technician knows, achieving a precise combustion chamber seal is non-negotiable for system safety and operational efficiency. This high-temp gasket provides a robust barrier between the burner manifold and the heat exchanger, effectively preventing combustion gas leakage and ensuring optimal flame stabilization within the unit. Engineered to meet exact OEM specifications, this part mitigates the risk of bypass air, which can lead to inefficient BTU output or resonance issues. When performing annual maintenance on Lochinvar Knight or A.O. Smith commercial water heaters, replacing a compressed or brittle manifold door gasket is the best practice to prevent carbon monoxide rollout and ensure the unit operates at peak thermal efficiency. This replacement heating part is built for durability, handling the thermal cycling stresses typical of high-demand HVACR equipment.
Key Benefits for the Contractor:
- Precision Fit: Specifically engineered for the Lochinvar 100276843 configuration, ensuring zero-gap contact with the burner assembly.
- Leak Prevention: Acts as a primary combustion seal to block flue gas migration into the mechanical room.
- Thermal Resilience: Fabricated from high-grade materials to withstand consistent high-temperature exposure without degrading or losing compression.
- Direct Compatibility: A genuine A.O. Smith replacement part that eliminates the guesswork associated with universal or after-market seals.
Common Questions:
When should this burner gasket be replaced?
Inspect the gasket during every combustion analysis or internal heat exchanger cleaning. If you notice signs of "cracking," "blow-by," or if the material no longer rebounds after the burner door is removed, immediate replacement is required to maintain the combustion seal.
Is this compatible with both Lochinvar and A.O. Smith units?
Yes. Because these manufacturers share various engineering platforms for commercial boilers and high-efficiency water heaters, part 100276843 is the standardized substitute part for specific 2-burner configurations across both brands.
Can I use RTV or sealant instead of this gasket?
No. Professional standards dictate the use of the OEM burner assembly gasket to ensure the exact spacing and sealing properties required for the combustion chamber. Using unapproved sealants can lead to hazardous gas leaks or component damage.
