TRIN, I had a four panel wedge with a 4 foot bell. I ran my pipes as in the bottom photo (second option) in Loyalist Dave's pics. I also had my uprights vary. I had a hinged ridge pole with 2(7') sections and uprights at the ends, without the stove. When I used the stove, I moved the rear upright 2.5' toward the front with a separate pin hole so I had more room in the bell. I was the only occupant in cold weather, which made it simpler for me. More room for the stove, it's fuel and room for me to work thee. Also, the most important tool or using a stove A FIRE EXTINGUISHER!!!! A Must.
