in THE MAIN WALL
I noticed it has a. vacuum / pressure gauge. I could see a call for heat , the vacuum pump turns on until the control sensors a vacuum. The shut off closes the pump from the system . Then the damper opens up to bring up the fire. The tank condenses any steam taking in between cycles. I only seen one remnent of a steam system vacuum pump. It pumped water though a fujiring. Sure there were many ideas back then

    Thank you all for your replies.

    On the top, behind the compound guage,there appears to be a B&G motorized valve, which is wired to a Penn thermal actuated switch on the side of the device.

    There are no numbers on the unit itself and all but one of the pipes have been removed. The one remaining pipe come from the top of the boiler to the motorized vavle.


    Here's a few more pics. Sorry for the poor quality.

    Thanks,

    my guess and only a guess

    it is the control and connection to a vacuum pump. What is the cut in and cut out read on that Penn control ?

    From the other post...

    I think you may be on to something, Ed.

    It has heat sink fins apparently. If so it must give up heat to ambient which in a steam system causes condensing/collapse, which creates a vacuum.... Maybe a way to lift condensate or speed up steam delivery?

    When we find out, there will be "ooooh!"s and "aaaaahhhh!"s and the occasional, "I knew that all along". I will not be in the latter category, I will say that right here.

    I think you're right

    it's too high above the waterline to be a side-arm heater. The motorized valve was made by Bell & Gossett.

    I sure hope you're planning to restore this system, with maybe a new boiler.
