Janitrol Automatic pilot

DPeak Member Posts: 3
Our very old hot water system has a pilot control made by Janitrol/Surface Combustion. It sends an electrical signal to a controller that opens the gas valve. The type designation is X O. It has apparently died, as bypassing it allows the boiler to fire. See picture attached.

Anybody know if there is a modern replacement part available? Or if there are any originals floating around?

    You should move this over to the"Gas Heating" forum and post it there. If anyone knows the answer to your question, it would be Tim McElwain.
