Thank you everyone, this is my first post but thanks to all your posts I ended up buying a Blaze King, and avoided a few other choices. So far so good. Chimney extended, lined (35’ of draft). I built a support beam in the basement (to support the old log sleepers), but a perfectly fine white oak floor, poured cement, and laid cement tile (and a little marble for the chimney baseboard) for a floor flush hearth.
