We want to add a wood burning stove to our bedroom/house wing. My wife
thinks it best to go up from the stove, 90 through the wall, and 90
through the metal awning. I say a straight shot through the roof with a
double walled pipe with no 90's, much less TWO.

Comments from anyone with experience appreciated.

Wall may be less prone to having the flashing leak. Outside in the cold,
more prone to creosote buildup. The 90's may make it easier to open and
clean though.
