I have removed an old Franklin stove and stovepipe but the chimney and ceiling hardware are still in place and I'd like to remove the ceiling connection (I assume the chimney pipe may come out with it unfortunately). I can't figure out how the hardware that supports the chimney pipe is installed in the ceiling. I've looked at it in the attic and I don't see anything to unscrew. I've posted a photo and illustration at

Thanks for any advice.
