Lochinvar & A.O. Smith 100208086 Ignitor Gasket Kit

The Lochinvar & A.O. Smith 100208086 Ignitor Gasket Kit is a critical OEM replacement part engineered for high-temperature sealing in gas-fired combustion systems. As a direct replacement for legacy part numbers GKT2449 and GKT2449K (also cross-referenced as 100146549), this kit is essential for preventing combustion gas leakage and maintaining the atmospheric integrity of the burner assembly. This high-density, heat-resistant ignitor gasket ensures that the ignition electrode remains properly seated and sealed within the combustion chamber, preventing erratic flame signals and potential safety lockouts. It is extensively used in Lochinvar Armor water heaters and Knight heating boilers, including models KBN, AWN, WB, and SNR/SNA/SBN. When performing routine teardowns or replacing a hot surface ignitor, installing a fresh Lochinvar 100208086 gasket is standard best practice to prevent air-fuel ratio imbalances or localized overheating. This precision-cut gasket kit provides the reliable seal necessary for high-efficiency condensing applications where moisture and thermal cycling demand durable, specification-grade materials.

• Direct OEM Replacement: Fully compatible with Lochinvar and A.O. Smith units, ensuring an exact fit for GKT2449K and GKT2449.
• Application Versatility: Fits a broad range of high-efficiency equipment, including Armor (AWN) wall-mount water heaters and Knight (KBN) boilers.
• High-Temperature Durability: Engineered to withstand the intense thermal stress found in modern gas-fired combustion chambers without degradation.
• Enhanced Combustion Safety: Provides an airtight seal around the ignitor assembly to prevent hazardous exhaust gas leaks into the mechanical room.
• Maintains Signal Integrity: Ensures stable ignitor positioning, which is vital for consistent ignition and accurate flame sensing during the startup cycle.

• Is the 100208086 a direct replacement for GKT2449? Yes, this is the current manufacturer-authorized replacement for original part numbers GKT2449, GKT2449K, and 100146549.
• Does this gasket kit work with Lochinvar Armor wall-mount units? Absolutely. It is the standard ignitor gasket for all Armor wall-mount water heater series and Knight series boilers.
• Why should I replace the gasket instead of reusing the old one? Combustion gaskets compress and harden over time; reusing a worn gasket risks gas leaks and "rumbling" combustion due to air infiltration.
