Well, I went ahead and bought my wood stove. After months of research I decided on an Osburn 2400 with 20' of 6" 316ti flex pipe through my existing masonry chimney. First off thanks to all those who gave me advice on this board and thru PM's. It was all very helpful. Over the last 2 days I've managed to scavenge up aver 2 cords of wood. Not bad for my first 2 days. The flex pipe showed up the day after i ordered it. Unfortunately they forgot the directions, but are sending them out in ther mail. Flex liners are all pretty much installed the same, right? Use high-temp silicone on the top cap, keep at least 1 inch clearance between the pipe and the masonry. My other question is do I need to use hign temp silicone on the flex connections to the stove and at the top where the cap meets the top plate? They have quick connections (pipe clamp style). Any other advice anyone has would be great. Thanks again to all. I'll let you know how it works out.
