New Sugar shack smoke stack question

[SRM]

I just built a 16x20 sugar shack with a 4x8 centered cupola. I can't seem to post a picture, but will try to explain the help I need.

I need to put the 10" stove pipe through the 8/12 pitch roof. I am concerned that if I put in between the rafters next to the cupola it will cause issues with the side flashing of the cupola. I also have 1x4 "purlins" nailed across
those rafters to help with nailing the cupola flashing down. If anyone has had a similar situation, please contact me. I can go between the next rafters where there is only metal showing; however, I would need to use elbows and a straight piece of pipe to reach it. Any help would be appreciated.
If you have help with posting pictures I will post a few as well.

Thanks
Scott

Hey Scott...pics always help. But, if you're concerned about the cupola flashing I would just use the next bay of rafters. I wouldn't worry too much about an elbow. If your stack is high enough you'll have plenty of draft.

If you go between the next set of rafters, why do you need elbows? Can you just move the evaporator over some? (I know that is easier said than done sometimes!!) I re-engineered my set up this year to get rid of the elbows. (I also went from a 6 to 8" pipe, put a new roof on and went straight up instead of out the window and up). If you can't move the evaporator, try a slight angle, gradually going from the evaporator and going to where ever it goes through the roof. Just a thought.
