Why Replace Your Firebox Gasket?
Over time, firebox gaskets can degrade due to repeated thermal cycling, exposure to combustion gases, and general wear. A compromised gasket can result in flue gas leakage, reduced combustion efficiency, and potential safety hazards. Replacing the firebox gasket as part of routine boiler maintenance ensures your NTI system continues to operate safely and efficiently.
