Just installed an Upland 207, the style that has the outlet on the back of the stove, not the top. So I needed 2 elbows to get to my thimble. Then another strike is that my chimney is outdoors. I measured the interior of the flue and it's 6x6.5. So I guess I should have known that this wouldn't be ideal, but I thought it would work good enough fro my detached workshop building. For the record, the chimney was already there, and the stove was free, so it's not like I went and designed this setup this way, just thought it might work out. Used 7" stove pipe as recommended by upland. Anyway, I got everything hooked up and started up a small fire this evening. The wood wasn't the dryest, but it eventually got burning decent. I checked outside to make sure my thimble connection was sealed properly and everything, saw a nice plume of smoke pouring out of the top of the chimney. Only issue is once it got burning good, I was getting smoke inside the room. One thing I know I need to do is seal the oval connection between stove and pipe, I will do that with some heatstop. I could probably use new gasket on the doors, I was seeing some smoke coming out around the main double doors when they were shut. Also however I was seeing some smoke that seemed to be coming out from the side of the stove.... seemed strange. It was hard to see really, but that's what it looked like. All in all the room was getting pretty dang smoky and I had to take my logs outside and extinguish the fire. All of this burn was done with the damper open, I wasn't snuffing the fire or anything. I figure if I had proper draft flow, small issues like old gasket wouldn't be a big problem. Any chance of making this setup work at all, or should i scrap the whole idea? I feel like the system has too many strikes against it, an outdoor chimney, a smaller flue size, and 2x 90s in the stove pipe....Would looking for a smaller 'box stove' type wood stove or something be more reasonable? Or am I going to need to go a different route if I want to burn wood. I'd love to burn wood up there, but it's just an outbuilding, so if I need to invest much it's just not practical. I know this is a lot of info, but if anyone has any advice I'd like to hear it.
