If you haven't found a solution to the smoking issue, let me relate my story. My Basement wood stove had a drafting issue and was very difficult to get started and had back draft problems and smoking whenever the fire got low. One day when trying to get the fire going and having a tough time of it, I stepped outside and noted a surge in the fire. Wow, what a difference. Thereafter, I opened the door whenever I had to start the fire or reload the stove when the fire was low. But, unless I wanted to leave the door open there was still smoke issues if the fire was not roaring away. I attached remake air from outside which did not seem to make a lot of difference, but the line was only 1 1/4 inch, I think now double that at least would be notable. Then one day I read about a draft assist fan. It cost around $140.00 bucks and I read some negative reviews regarding the not air tight fit, and when it arrived I noted it said not to place within 2 feet of heat source or let it get over 90 degrees F. So I talked to the company tech who advised "do not put it close to a bend but that I could place it outside in the horizontal section. So I placed it outside where a little smoke leaking is no issue and there is no chance of it getting to hot. It has a reostat which I wired to the inside of the house (no problem) and set it on high sometimes to start the fire if I don't have pine kindling around, and otherwise leave it on low. Wow, no more smoke issues. I could almost dance a jig. One problem I had was if I turned it off and it set awhile the fan would stick and I would have to reach the stem with long nose pliers and turn it to free it up. After doing this twice I elected to just let it run on low all the time, Electric use is not notable and because I had run in remake air from outside, it doesn't pull heat from inside. In reflection I wonder if I could of got off cheaper by buying a heating duck assist fan which is the same size and looks exactly the same only it is silver vice black. Because It is located outside in a low heat area I think I could have, and they run about $60.00 bucks. I have run this unit all winter from November and even still when it gets cold. Life is great without smoke in your face. Just look up draft assist fan on amazon and it should bring it up. You cut a rectangle slot in the side of the pipe and attach with 4 screws. The paddle wheel fan dipps inside the pipe and helps to pull the draft from the stove on out. The pull is strong enough that when you take the ash out of your stove if you keep the can or box tilted in the door it will such all the airborn ash up and out the chimney. Good Luck.
