Nti 82769 Ceramic Burner Door Disc Ti Series

Product Description

The NTI 82769 is a ceramic burner door disc designed as a combustion-side replacement component for the Ti Series condensing gas boiler line. This disc seats at the burner door assembly and serves as a thermal barrier and sealing element between the burner and the heat exchanger enclosure. Its ceramic construction withstands the high-temperature cycling inherent to condensing boiler operation. Installation is typically performed by a licensed heating contractor or plumber during a burner service, combustion chamber inspection, or heat exchanger access procedure.

This component is matched to the Ts80 and Trinity Ti Series condensing gas boilers. It is a direct OEM-style replacement part intended for residential and light commercial hydronic heating applications where the original disc shows cracking, erosion, or deterioration from thermal stress. Replacing a damaged burner door disc restores proper combustion geometry and prevents uncontrolled flue gas migration at the burner assembly.

Key Features

• Ceramic construction rated for sustained high-temperature exposure in condensing boiler combustion chambers
• OEM-matched fitment for Ts80 and Trinity Ti Series boiler models
• Serves as a thermal barrier and sealing disc at the burner door assembly
• Direct replacement part minimizes downtime during boiler service calls

Compatibility

Designed for use with the NTI Ts80 and Trinity Ti Series condensing gas boilers.

Installation Notes

This part should be installed by a licensed HVAC technician or plumber qualified to service gas-fired hydronic boilers. Before accessing the burner door assembly, shut off gas supply to the appliance and allow all components to cool completely. Follow the boiler manufacturer's service documentation for proper disassembly sequence and torque requirements. Verify combustion integrity and check for flue gas leaks after reassembly before returning the system to service.
