Hello have a few questions, I got a little wood burning stove TMS 2346 works great burns hot I was thinking of installing it in a small 10x12 cabin, I was going to modify the pipe to go into the stove 2 3/4 collar fully aware of creosote build up, I also plan on setting it on 3x5 wonderboard + tiles on the floor and on the rear + a pipe shield I was going to keep it 18 to 24" from rear and from ceiling, using 34" single wall 2 3/4 pipe that came with it, then use the Duravent ac 3100 4" kit, adapt the 2 3/4 stove pipe to 3 to 4 connecter to the 4" double sided elbow from 3100 kit and add double sided 4" Duravent to AC3100 kit through thimble attach to the T and up the roof add more 4" double sided Duravent to reach the roof, I like the 3" clearance from wall. I asked Home Depot as I was getting ready to buy the AC3000 229 + tax Its 3" double sided, the guy asked where I was installing Its going to Cloudcroft NM 8600 ft elevation then he suggested the 4" AC 3100 kit its for higher elevations and vents better I mentioned the 6" and they said it would overdraft and would probably require a damper to adjust the vent. They think the 4" kit is perfect for a tiny stove with a tiny 2 3/4 collar. I think 6" would be expensive and a bit overkill for a tiny stove, but still consider it. Its a secluded small 10x12 cabin and space is really tight that little stove measures 10W x 18L x 11H it measures 26H with the legs installed it heats up great, cooks, and would fit just right. Also sadly there are no kits for that specific stove and it came with no instructions or clearance recommendation but it works great thinking of getting another for my 18 x 20 sheet metal garage. My question is can I use the pellet stove AC 3100 horizontal kit for a small wood burning stove? I think this kit would get me going in the right direction with a few additions or is 6" A class chimney pipe a code requirement regardless of stove size? Thanks for all the info. have a great weakened and wish you all happy holidays. -sd
