You have sent me an answer on the basement exhaust fan. My second part of the question is, can we put the pipe into the chimmney hole? We have a high eff furnace and are not using the chimmney. It is right beside the furnace would that be too close to use to exhaust?
Answer:
No, you cannot. The humidity you're exhausting will create mould and mildew that the chimney (metal or masonry) would never be able to survive.
