Keep your Utica-Dunkirk boiler operating safely and efficiently with the genuine OEM 550002586 Replacement High Limit and Low Water Cut-Off (LWCO) Kit. Designed as a direct factory replacement, this kit restores the critical safety control functions that protect your boiler from overheating and low-water damage — two of the most important safeguards in any hydronic heating system.
Product Overview
This kit bundles the high limit control and low water cut-off (LWCO) replacement components into a single, convenient package. The high limit control monitors boiler water temperature and shuts down the burner if temperatures exceed the safe operating threshold, preventing damage to the heat exchanger and associated components. The LWCO device monitors water level within the boiler and interrupts burner operation if water drops below the minimum safe level, protecting the boiler from dry-fire damage.
