We just bought a used 1986 Vermont Castings Defiant Encore but now are wondering if we made a bad purchase based on how the pipe lines up, or rather, won't line up. Do they make oval to round elbows? We need a pipe that takes it from 10 1/2" wide oval to 8" round. Is this possible? We paid $325 for the stove and it reportedly was barely used. It was in a nice island home that was only used as a summer house before the current owners bought it and they replaced it with a gas stove. We have been trying for weeks to try to figure out how to hook it up and are really needing help. Thank you.
