Re: How to demolish a brick chimney
Those type of chimneys are easy to tear down and require no more than a hammer and masonry chisel. You start at the top and tap the chisel into the mortar between the bricks to release the bricks. You will need a cleared area and container to through the bricks as they are removed. If the fire box is in good shape you would only need to remove the chimney down to the fire box. Once removed the top of the fire box would need to be sealed (fireproof) and a gas log set can be installed to the fire box. You can install a direct vent unit or a vent-less set. If the fire box is unsafe you will need to rebuild it. If you install a vent-less set, while generally safe, it is recommended the a CO monitor be installed in the cabin.
I tore down one of the chimneys in my home in 2 days working by myself, but I did use a compressor and air chisel.
