hi, i was thinking about some of the info in my other post, if i run double or triple wall pipe out through the tin roof once i get outside how does it go from double.triple wall back to single wall ??? what keeps the water from running back down between the walls of the pipe??? thanks

Adapters.

Unless money is an issue I would stick with the better pipe after you change over to double or triple wall, how much pipe will you have above the roof line?

Oh, I might have mis-read. On your way up, once you go to triple wall you can't go back. That means if you have triple wall in your house it needs to go all the way to the chimney cap. Single wall pipe is for going from the stove to the chimney as a connector only, it is NOT safe for outside use.

If you are going to stick with the single wall pipe (not recomended as you know from the posts in your other thread) you very well might have to have some thing made for you at a welding shop.
