Sorry for the lack of getting you up to speed before sending you out on the turnpike to play.....First, I see you just joined, so WELCOME, second sorry I missed it. You are among friends her, so the learning curve will be a little steeper.
I am off to a jobsite, but I promise to be back later. You are in good hands for now, just don't lose you patience, however, I do think you need to get a 't' and a barometric damper before you go too far. The big box guys should have both.
I wouldn't burn without it. You apparently have a good draft.......keep asking, and you will learn quickly.
