The LOCHINVAR L100208560 is a sensor inlet kit designed for monitoring inlet water temperature in high-efficiency condensing boiler systems. The kit provides the sensing assembly needed to accurately read incoming water temperature, allowing the boiler control system to modulate output and maintain efficient operation. It is a direct-fit OEM-style component installed by licensed plumbers, hydronic heating technicians, or mechanical contractors during scheduled maintenance or sensor replacement service calls.
This sensor inlet kit is rated for use with the Knight Model WH series wall mount boilers, covering the 56 through 400 MBH output range. These wall mount boilers are commonly installed in residential and light commercial hydronic heating applications. The kit addresses inlet-side sensing, making it relevant for service calls where the inlet temperature sensor has failed, drifted out of calibration, or been damaged during routine system service.
Designed for use with the Lochinvar Knight Model WH 56 to 400 Wall Mount Boiler series.
Installation should be performed by a licensed plumber or qualified hydronic heating technician. Before servicing, shut down the boiler, isolate the system, and allow it to cool to a safe handling temperature before removing any sensors or fittings. Follow all applicable local mechanical codes and the boiler manufacturer's service documentation when replacing inlet sensing components.
