A few weeks ago I picked up a Buck 91 Bay from my chimney sweep guy for $300.00. I have been trying to figure out how to install it while saving the existing damper. I decided to go with a direct connect for now due to cost. I ordered an offset box to move the opening to the side as to clear the damper handle along with 7" oval to round flex pipe. The stove has a 8" flue but there is no way I was going to be able to ovalize an 8" pipe enough to fit through the 5" damper. So instead of choking the stove down with a 6" I opted to go with a 7" pipe. The pipe arrived today and that's were the excitement ended. The pipe ended up not fitting through the damper as originally planned and some tugging, pushing and persuading later I got it to fit through the damper. At least to the point that it hit the back of the chimney, this is where it all came to a stand still. Trying to get the pipe to turn up was just not going to happen so I tried to push it up while my wife tugged, pushed and persuaded it up the damper and then I noticed the hole. :ahhh: Had to get it out to see if I could some how fix it but it only started to unravel like the line on a spinning reel on a long cast. Guess I should have gone with the 6" it would have made it through the damper easier and perhaps made the upturn easier. That retrospect 20/20 thing really sucks! And its expensive. So cut the unraveling pipe and was able to save 3 feet of it. I again tugged, pushed and persuaded it up the damper to the point where the oval meets the round and were done. No more movement allowed. I now have too much round sticking down and with the addition of the offset box and reducer I need to somehow reduce the amount of pipe that is hanging down. I figure it unravels nice and easily so I was going to try and unravel it enough to fit the offset box under it and secure it to the unraveled pipe. This should be interesting considering that the stove weighs 575lbs and I do not have very much wiggle room. I do not want to start the unraveling until I get the stove in place with the offset box so that I can see just how much I need to unravel. I see a lot of heavy moving in my future. In any event here are some pics of the current attempt at install and ruining 5 feet of flex that was too big. I will post more pics of the process as well as pics of the stove, and hopefully some of the first fire. I hope there will be a fire and not just a smoke storm due to a short direct connect, but only time will tell. If anyone has some 6" round to oval sections laying around I would be glad to take it off your hands. haha.
