Weil-mclain wm383600069 Low Water Cut Off Kit Ulc for WM97 Plus and Slimfit Boilers

Product Description

The Weil-McLain wm383600069 is a Low Water Cut Off Kit designed for use with the WM97 Plus and SlimFit gas-fired water boiler systems. This safety kit meets CSA applicable standards and is a direct-fit replacement for qualified Weil-McLain boiler models including the ULTRA 550, ULTRA 750, and SlimFit series. Low water cut off devices are critical safety components in any hydronic heating system. Their job is to monitor the water level inside the boiler at all times. If the water level drops below a safe threshold, the LWCO automatically shuts down the burner to prevent dry firing, overheating, and potential damage to the heat exchanger. Without a functioning LWCO, a boiler running low on water can suffer catastrophic failure. HVAC technicians and boiler service professionals rely on OEM replacement kits like the wm383600069 to restore proper safety function quickly and with confidence. This kit is engineered specifically for Weil-McLain condensing boiler platforms, so installation fits the existing mounting points and wiring connections without modification. Using the correct OEM part ensures the safety circuit performs as the boiler manufacturer intended and keeps the system within warranty compliance. The ULC designation on this kit confirms it meets Underwriters Laboratories of Canada certification requirements, which is important for installations subject to Canadian safety codes. Whether you are servicing a residential or light commercial heating system, this replacement LWCO kit provides the reliability expected from Weil-McLain boiler components. It comes backed by a 1-year limited warranty, giving contractors and building owners assurance in the quality of the repair.
