We are in midst of remodeling my late uncles 1800's farmhouse. There is a Rumford Brick fireplace in the middle parlor.Built in the mid 1800's. In good shape, but all brick and no flu liner. To renovate it to burn wood ( and meet codes) I was told the whole chimney would have to be dismanteled down to the firebox, a flue liner and damper put in and the brick replaced. At a cost of aproximately $ 4,000! Can I put a gas log insert in with just the existing brick?Or can I put an insulated steel pipe up through for gas logs? Anyone else have a brick fireplace that is similar? I did have a block chimney with tile liner built on end of house for a kitchen wood cookstove so will have some wood heat. But I would love to use the original one too ( and not burn down the house in the process.
