Lightning wrote:I have the stove pipe in the basement from the furnace to the flue all put back together. My 6 inch stove pipe goes into an 8 inch square flue. I sealed around the pipe with tightly packed fiberglass insulation. I didn't know what else to use, and I know that stuff doesn't burn very good lol. Is there something better I can do there??
take a pic. so we can give some advice or idea to fix the problem. You might be able to put thimble in,also the insulation might let extra air up the chimney and effect the draft.
