    Flue Access Covers Legal in U.S.?

    I see all kinds of flue access covers being sold in the U.K., but not here. Could it be a code issue? You use a hole saw and then wrap this around it with a high-temp liner. What could go wrong? https://www.stoveindustrysupplies.com/stainless-steel-flue-access-soot-door-cover-6inch
