The NTI 82659 is a manifold limit device designed for use with NTI Ti100-200 series condensing gas boilers. This component plays a critical role in the safe and reliable operation of high-efficiency condensing boiler systems. The manifold limit functions as a safety control that monitors temperatures within the boiler manifold. When temperatures exceed a set threshold, the limit interrupts operation to prevent overheating, heat exchanger damage, or unsafe conditions. This makes it an essential part of the boiler safety circuit and a key component for HVAC technicians performing service, maintenance, or repair on NTI Ti-series equipment. The 82659 features a 1/8 inch BSP threaded connection, which is a standard British Standard Pipe fitting size commonly found on European-origin and Canadian-manufactured heating equipment. NTI boilers are well known in the hydronic heating industry for their compact design, high efficiency ratings, and reliable performance in residential and light commercial applications. The Ti100-200 series covers a range of condensing gas boilers from 100 to 200 MBH output, making them a popular choice for forced hot water heating systems. When the manifold limit fails or trips without resetting, replacing it with the correct OEM part like the NTI 82659 ensures the boiler returns to proper operation without compromising system safety. HVAC technicians and boiler service professionals should verify compatibility with the specific Ti-series model on site before installation. Using the correct replacement limit control maintains the integrity of the boiler safety system and supports proper certification and warranty compliance. This is a direct OEM replacement part sourced for trade professionals who work on NTI hydronic heating systems regularly.
The NTI 82659 manifold limit is a direct OEM replacement safety component for Ti100-200 series condensing gas boilers. It provides reliable temperature-based protection for the boiler manifold and is a critical part for HVAC technicians servicing NTI hydronic heating systems.
