Lochinvar & A.O. Smith 100151693 Frame End 340793-762 5-watt resistor across the "Y"The Lochinvar & A. O. Smith 100151693 Frame End (also identified by part number JKD6187) is a critical structural component engineered specifically for the V baffle assembly in high capacity commercial boilers and water heaters. This heavy duty frame end provides the necessary lateral support to maintain the alignment and stability of the internal baffle system within the heat exchanger. By rigidizing the V baffle runner, it prevents mechanical
