You would be pretty thin if 2" was roomy! you have 2' correct?
Yes, I was saying 2" from the stove MFG to what ever space would be comfortable to work around it.
Check with MFG on chimney total height they usually say min 15 feet.
I don't see where you come up with a min of 15' chimney height? From reading the mfg requirements they all seem to go by the min of 3' above the roof and two feet above the ten foot reference line. Which it seems 4' would be high enough for my chimney going up through my flat rubber roof.
Baro can be put in a tee with double wall pipe, that is what I did.I can provide a picture.
Newbie question, they don't come already installed in a tee you have to put them in there yourself?
