Hello, I recently just purchased a house and in the garage there is a franks piping wood/oil burner, BNH-W model 2-175. If am looking for an installation manual or any info on it would be great. I am mainly looking for the wiring aspect of it. There are two thermostats, 1 for oil 1 for wood. There is a main switch. There is a high low limiter on top of the unit which to me acts as the aquastat for both. Then from there there are two more high/low limit switches, a transformer and an on/off switch for both oil and wood. And also the motor, and ignition unit for the oil side. Any info or diagrams would be greatly appreciated.
