Metal Like Asbestos Chimney
This is the second time I have run into this type of furnace chimney. The previous time was about 10 years ago in upstate New York.
It appears to be asbestos. When I look at the pipe from the end, I see layers of material. When I tap it it rings almost like cast iron pipe. It has the visible connector here and another in the attic. I cannot determine how they are connected; not with screws though. The rest of the chimney is behind the interior walls. On the roof it has a b-vent style metal boot, storm collar and rain cap. There are no labels or imprints on the pipe that I can see.
Has anybody got any experience with this material?
