Hi, I found this forum and thought I would ask. I am getting ready to install a pellet stove using a Duravent AC-3000 3" vent kit. It is going to be a corner install with the stove diagonal. The corner that I am installing it in has a larger than 90 degree angle, so I am trying to find a 3" elbow that is 30 degrees (rather than the 45 degree elbow used in a corner that is 90 degrees). I see a few references to people saying that they used a 30 degree elbow, but I can't seem to track one down anywhere. Any help would be greatly appreciated. Thanks!
