I know hindsight is 20/20 but why did you put your thimble so low? Even with a rear exhaust stove you could have elbowed up and out. Now you're kinda stuck if you ever change stoves for some reason.
Well, I didn't have much wall to work with... short walls. Mostly t&g roof. If I ever have to change this stove out, the new stove will go against the wall in front of the window and vent through the roof... where begreen suggested a while back
I was almost to the point of just relocating it to that spot... but I've already done so much work. Though... I enjoy the work.
See... short walls
