I will admit I have never seen this so any information about this will be greatly appreciated.
Thank you,

Thank you,
Haha! That’s old, no model number visible anywhere?
It looks like an old coal burning furnace, commonly known as an octopus, that was converted to burn gas. It is probably about 55% efficient, which means that for every dollar spent, $.45 goes wasted up the chimney. It is gravity heating…no fan that I see added. An upgrade would pay for itself in short order.
