We recently acquired this 1940's Cap Cod. It appears there was a gas insert or stove in the fireplace at one time (see gas pipe in pic). The outer brick on the chimney looks good... the inner chimney (see pics) is baaaad and dirty! Notice there is no damper or cap at all. I'm hoping I can slide in a woodburning insert with associated SS liner with insulation. Of course, I'll clean it up first... and I have a couple of family members who can fix up the brick in the fireplace as needed. I'm not so interested in heating (the rest of the house if fairly new and efficient) as I am having an occassional nice fire to relax by. Warnings? Comments? Suggestions? All appreciated! Thanks!
