Hi folks, new to this forum, and glad to have found it. We've had a small Century wood stove for 7 years now, and we love it. We recently remodeled our home, and that included moving the stove to a new location. Our contractor installed the exterior chimney. We bought a new double wall 6" telescoping black pipe for the interior. However, when I tried to install it, it seems that the connection doesn't work...same diameter, so the male piece won't go in the female piece that the contractor installed. Not sure if it takes additional crimping, or if there's supposed to be an adapter of some sorts?
