Hello.Finally got the supervent chimney install done.Not too bad but fooling around with stovepipe was more work than i thought it would be. OK I have a Fisher papa bear.It has a UL tag on the back of the rear heat shield but it has no baffle.I had read that the UL ones would have a baffle.What can you guys tell me about the stove?Also,If i make a baffle can I use stainless steel?Thanks.
