    A steam boiler electrical runs in series. Not sure voltage of boiler wired. But you can wire #67 line voltage to shut down any just about any unit other then a millivolt gas system. I will wire it line voltage to control the feeder.. With a millivolt system ..Then it will be duel voltage to control the feeder and gas burner. The top two terminals are for the burner. The bottom two are for the feeder. There is a jumper Chanel to bring the line down to the feed switch .. The load will be the other terminals..
