This Burnham Commercial assembly is a Low Water Cut-Off (LWCO) and Wiring Harness (WRG HRN) combination. The LWCO is a safety device designed to shut off the burner or disable it when the water level in a boiler drops below a certain point. This prevents the boiler from operating without enough water, which could cause significant damage. The WRG HRN, on the other hand, is an integral part of the electrical system of the boiler. It provides a secure and organized method for connecting various electrical components within the system. Together, these two components form an essential part of maintaining safe and efficient boiler operation.
