Hey, Im new here. I just bought a used fisher teddy bear (yes a teddy bear, not a baby bear. I checked the tag on the back.) and the only place that I can install it in my house is in the living room in the dead center of the house so if I exist the pipe straight up (which I want to because it will draft better) It will exist right through the ridge. The house has trusses so there is no ridge beam, but I'm wondering if they make a pre fab flashing for the pipe that will fit over the ridge? Can help would be appreciated. Thanks in advance.
