Hi, this is my first post....the guys at woodnet.net suggested I ask my question here since it is about a stove. I have a Baby Bear type little freestanding stove. I also have a heartch with a functioning fireplace. I was considering two types of installs. 1. I was going to place the stove on a pad (2x2 frame with plywood, backerboard and ceramic tile) directly in front of the hearth with a pipe exiting the back of the stove and entering the firebox. I was going to have a sheet of metal closing off the firebox so the pipe would go throught the sheet material with an elbow pointing the smoke and let the chimney draw. 2. It was suggested by some on the other site that I run the pipe all the way up the chimney and insulate around the pipe. If so, do I need inuslated pipe? or fireproof insulation around the pipe? Also, the previous owner took the damper from the chimney, so I have a rectangular hole there. If the pipe should go up past that, is it ok to extend the pipe through the rectangular hole and reshape to my needs? The factors for decision making are obviously safety. Both short term and long term. Second is cost. I already have the stove and the sheet metal was free. I appreciate any help. I have made about 6 calls in 2 days to the county/city and I can't get anyone to answer my calls.
