When we bought our house there was a stove insert in the fireplace, but it was not up to the current codes, so it had to be removed before the sale could be final.
"John answered them all, saying, “I baptize you with water, but he who is mightier than I is coming, the strap of whose sandals I am not worthy to untie. He will baptize you with the Holy Spirit and with fire." Luke 3:16
Addendum: Somebody wrote and was worried that it was up to code and approved by our insurance company and I wanted to tell you that yes, the stove, the pipes, the fireproof insulation is all up to code, approved by our insurance agent and totally safe. Also, my husband found out what that stuff was that he cleaned out of the chimney, it was fireproof insulation that the previous owners set at the back of the old stove just because they had extra material.
