Nti 82770 Ti Burner Door Fkm Gasket for Lx150-500 M100V Ti100-400 Ts80 Condensing Gas Boiler

Product Description

The NTI 82770 is a burner door FKM gasket designed for use with NTI condensing gas boilers. It is a direct replacement seal that maintains a proper combustion chamber closure at the burner door. Condensing boilers operate at high efficiency by extracting additional heat from flue gases, which means the burner door seal is exposed to elevated temperatures, moisture, and combustion byproducts over time. A compromised gasket can allow flue gas to leak into the surrounding area, reduce combustion efficiency, and create unsafe operating conditions. The NTI 82770 uses FKM material, which is a fluoroelastomer known for its excellent resistance to high heat, fuels, and chemical exposure. This makes it well suited for the demanding environment found at the burner door interface of a condensing gas boiler. HVAC technicians performing routine maintenance, combustion tune-ups, or burner door service will recognize the importance of replacing this gasket whenever the burner door is removed and reinstalled. Installing a fresh gasket ensures a proper airtight seal is restored and that the boiler returns to safe, efficient operation. This part is compatible with a broad range of NTI boiler models including the Lx150, Lx200, Lx250, Lx300, Lx400, Lx500, M100V, Ti100, Ti150, Ti200, Ti250, Ti300, Ti400, and Ts80. Having the correct OEM replacement gasket on hand reduces callback risk and keeps service visits efficient. This is a genuine NTI replacement part, sourced for professional HVAC installers and service technicians who work on residential and light commercial hydronic heating systems.
