Description
The NTI Boiler 6000083808 Door Ceramic Disc seals combustion chambers on LX150 and LX200 boiler models, creating a heat-resistant barrier that contains flames and exhaust gases during firing cycles in HVAC systems. It withstand extreme temperatures while maintaining dimensional stability that prevents warping or degradation under thermal stress. Placed between door assemblies and firebox openings where proper sealing ensures efficient combustion and prevents heat loss to surrounding areas. High-density material resists cracking from rapid temperature changes during startup and shutdown sequences. Precision-cut edges provide consistent contact surfaces for leak-free operation.
