Hey guys could use a little advice. I am putting my englander 30 woodstove in my basement and was planning on a class a chimney stainless set up, but starting to think about masonry instead. A little background info..... its going in my basement so it will have a 90 then once outside will have a 18' run. The main reason i'm thinking masonary is for looks, but will a class a insulated system do a better job of drafting since it will be a outside application? Would I be better off going with class a then building a chase around it for looks?
