Decided to add an exhaust fan to the boiler hoping the Mrs. won't let any smoke escape when loading. Could not find 5" duct at the local Lowes so I went to a heating/plumbing supplier and they said not to use semi rigid aluminum as it will probably melt?
I think the material is rated to 400 degrees, surely the exhaust smoke does not have a temp anywhere near that? Another WG owner uses galvanized duct work but I was thinking the semi rigid stuff would be an easier install.
