Thanks for the reply. I like how the doors are hinged. Do you have any photos of the stack and roof jack. I’m thinking I want to go out through the peak and want to see how it is on the inside and up on the roof.

Due to the fact that we do not have a ridge beam - rafters are connected at the top with wood pegged mortise and tenons - installing the stack was pretty straight forward.
I just cut out the 2X8 roof decking between rafters and ran it up through the opening and into the roof jack.
The roof jack was from Leader and matched the 12/12 pitch of the roof.

First picture shows the stack going up through the roof and into the roof jack.
Second shows the ceramic blanket with a metal cover to protect the roof area.
Third is a picture of what our roof jack looks like from Leader's site.

Hope this is helpful. John

Are my eyes playing a trick on me, or do you have an offset just before entering the roof jack?

He had to get between the beams.

Yes I do Dave. I had Leader fab the last pc of stack so I could clear the rafters. Nice catch

I would of needed an offset too, but when I was building my sugarhouse I planned where the smoke stack would be and moved 1 truss over 6" so the stack goes straight up thru.
Then I later got new pans and it came with a SS hood. One of the steam stacks was "in the wrong place" so I had them make a SS offset for that steam stack.
