Functionally my woodstove works great. I'm using durablack stovepipe into a duravent triple wall that is run inside my old brick chimney. Now I'm going to do some aesthetic upgrades to the mantle and fireplace area, and I'd like to properly center my woodstove in the fireplace space. A straight run from my chimney to my stove via the stovepipe puts me a couple of inches off center. Is there one six inch fitting that can do this or do i need to get two 45 degree fittings?
