Firomatic Fusible Oil Valves
I am doing some research for a paper on oil heating. I live in Massachusetts where they use a thermal cut-off switch above the oil burner that will disconnect the power to the burner should the temperature reach 165 degrees. They also use an oil safety valve that stops the flow of oil should the same condition occur. I believe this is part of the Massachusetts code. Does anyone know if other states require the use of such devices?
