Just an update on the situation.  This morning, nice temps. here, no humidity.  I go out for a nice lunch, go home and BINGO.  The room stinks like fireplace.  It is hotter and more humid here and the ATTIC EXHAUST FAN IS ON.  I should note, it is a small round exhaust fan.  So, since the fan is hardwired, I disconnect it and will see what happens tomorrow.  What is extremely confusing to me is that there is a damper on the flue at the roof and a pillow inside, yet the the room stinks.  So, let's see what happens?  Also, any other advice is appreciated!
