We bought a 'through the wall' stovepipe kit and it came with a thimble. The yurt company had already installed a stovejack into the exterior wall, and we are wondering with the stovejack installed already if we need to also use the thimble that came with the stovepipe kit or... can we just exit the yurt through the stovejack using triple wall stovepipe? We've looked online and have both yes and no answers...
