Installing the stove in the finished basement. Currently the wall is studded out and drywalled, but I plan to remove, re-do, the area behind the stove. It'll likely be steel studs and stone veneer. I'll insulate that area as well. The issue I'm having is what to use to run through the poured wall. The "through wall kits, give you a thimble and class A pipe to use when running through a framed wall. Since I'm going through a hole in the concrete, do I really need all the thimble stuff. Couldn't I just run a section of class A through the hole and mortar around it, add an adapter and run the stove pipe down to the stove? I guess the thimble trim would dress it up, I'm just not sure if there is a way to do it so I'm not buying pieces I don't need.
I am just finishing this exact setup. Some manufacturers caution against no thimble because hot spots could develop inside the pipe. I ultimately chose to use a thimble. The Selkirk wall thimbles are the one piece that doesn't feel too overpriced. You would probably be fine without one in the end.
The hard part with this setup is the long horizontal run. I'm not too thrilled about it. Are you going to offset any overhang?
I don't have any overhang on the side of the house it exits. I need to figure out how thick the wall is. I have glass block in the windows, so I'm struggling to figure it out without drilling a hole. I'll have to guess on the dimensions I know for now. I know the outside offset from the glass block face to the outside of the wall is 3.5". The inside offset is 2". If the block is 4" I should be between 9"-10" thick.
Poured walls are either 8 inch or 12 inch normally. I like skeeters solution above, clay? pipe sleeve. I cored out thru poured wall and then used hydroment to seal instead of mortar.
thats single wall 8" but i used to have class A double wall 6" going thru it....it fits almost prefect. when i originally did it i brought a section of class A with me to the lumber yard to make sure it fit the clay thimble.
I contacted Selkirk with this question before my build. I was told that no thimble is required... Since you'll be going through your wall, then through a studded wall, you'd have to make sure the entire path of the class A maintains clearances. A thimble could be used here and gives a finished look. I really need to get that build thread on here, don't I? Lol
The studded wall I go through will either be steel studs with concrete board and stone veneer, or just stone right on the concrete. I won't have to worry about combustibles except the ceiling area.
