I discovered this furnace in a home I inspected this afternoon. Anyone have an age? My preston’s guide goes back to 1965 and is not listed.
There was a hole in the vent pipe that looked like it was designed to be there. Very odd to me. It was open to the basement with a peice similar to a damper in the middle. Any ideas of what this is? Is it safe?
Also, this was the first time I have encountered a furnace this old. Tried to explain it was old but I really did not know much about it. I think I did ok BSing my way out. Any tips for future encounters.
