So in the dead of winter last year, I moved into my current house which has this beast sitting ominously in the basement. I'm curious as to what the heck it is? It has no markings what-so-ever anywhere. I can give you some specs about it though! The basement was finished in 1976, so I can only assume this was new around then. This behemoth has a 5.5 cu. ft firebox, the flue is 10" pipe (recently reduced to 8" by myself) and vents to an 11x11 chimney. It's about 3.5' wide x 2.5' deep x 2 feet tall. Any help would be most appreciated, as I'm not sure how much longer the blower in it will last. P.S. - I can't say enough positives about this forum and site!
