I am trying to install a restored antique wood cook stove and the township inspector is giving us a hard time. We were told by him that we cant install an old stove. But I read online that If a stove is manufactured before 1981 it will not be UL Listed and it is grandfathered in. I found this information on a website but PA uses the UCC and I am unable to find anything online. Any information would be greatly appreciated!! Thank you all.
