I made a barrel stove.

So the plan is to make a waist high wall of cinder blocks around my patio, excluding an area in opposing corners where the doorways are. Currently the patio is covered with corrugated plastic roofing, like so, that is being held up by an aluminum frame.


I'm planning to trade the plastic for metal.


Now stay with me here. The patio is backed by two brick walls on my house, and two open sides. I'll be putting up the waist high cinder block wall on the two open sides, leaving a door way at each end where the wall would meet the house. The stove will go in the corner where the cinder block walls meet. I want the cinder block wall to go to the ceiling in the corner where the stove is. I'm thinking maybe 2-3' out from the corner on each side. The plan is to run stove pipe up that corner, and instead of cutting through the roof, dog leg the chimney through the cinder block wall through the second to top row of blocks. Then I'll run it slightly over the patio roof and put a rain cover on it. I was thinking that since all this will be outdoors, only partially enclosed, and not near any combustable material, I could get away with using cheaper single wall chimney pipe that I wouldn't use inside of a structure. However, looking at this picture, I wonder if single wall will be an issue. Thoughts? This patio I described is approximately 8' x 14'.
