I recently bought a Vermont Castings Defiant Encore stove. It will be put on first level. It will need to exit the interior wall (straight forward). The complication(s) begin from that point on. Attached are two photos showing the porch, and then the side of the house. Does anyone have any advice on how to run the pipe? Do I have to run it through the porch roof/ceiling and then up the side of the house, or do I run it horizontal along porch (6ft span) then up 4 or 5 ft? Once this is explained, any advice on a specific pipe would be great. Thanks.
