New to the the site have enjoyed reading everyone’s posts. I have ordered a Blaze King king 40 model. Is it acceptable to have 8” double wall from top of stove to celling ~65” then reduced to triple wall 6”for another ~14f?. This is my current set up with a older Appalachian stove. If left this was what would it hurt if anything ? Attached pictures of current set up. Thanks for everyone help.
