Gentlemen, I'm in desperate need of help completing my stove pipe install. I have 2ea 3' sections and 1ea 2' section of pipe. That leaves me 18" to tie into the 8" ceiling box. I have an offset to cope with also. I have my 8x3 adapter which takes up 7" leaving me 11" to be able to connect my pipe. A adjustable slip connector doesn't work and neither does 2ea 8" 45 degree ells. I'm at a loss what to do. Can someone please give me some in site on how to proceed? Any help would be greatly appreciated. I've attached 2 photos showing my condition.
