Nti 82763 Llh Kit Composite Flue Box TRX150 199 199C Ftvn

Product Description

The NTI 82763 is a Low Loss Header (LLH) Kit with a composite flue box, designed for use with NTI TRX150, 199, 199C, and FTVN series condensing boilers. NTI is a well-known manufacturer of high-efficiency residential and light commercial heating equipment, and the 82763 is a factory-matched replacement and installation component for their popular TRX and FTV boiler lines. A low loss header is a critical hydraulic component in hydronic heating systems. It acts as a buffer between the primary boiler loop and the secondary distribution loop, allowing both circuits to operate at different flow rates without interfering with each other. This improves system efficiency, protects the heat exchanger, and ensures stable operation across varying load conditions. HVAC technicians and hydronic heating professionals rely on LLH kits when installing, servicing, or upgrading multi-zone or high-efficiency boiler systems. The composite flue box included in this kit is designed to work seamlessly with the venting and combustion components of the listed NTI boiler models. Composite construction offers resistance to condensate and corrosion, which is important in condensing boiler applications where flue gases are cooled to the point of moisture formation. Using the correct OEM-matched flue box ensures proper draft, safe exhaust routing, and compliance with appliance installation standards. This kit is sold individually and is the correct replacement part for technicians working on NTI TRX150, 199, 199C, and FTVN boiler installations. Always verify your model number before ordering to ensure compatibility.
