OK, I've been studing all the replies to my 2 posts. At first I thought maybe it was a negative pressure problem. But after I started a new fire twice with the window cracked I didn't see any difference with my smoke problem. Its really cold out today so the difference between inside and outside temp is great. But I was still thinking I had a draft problem because when I try to start a fire smoke just pours into my house. But I went outside when I was having this crazy smoke inside and smoke was coming out the chimney too. So, I'm wondering if this wood is new could that be my only problem? My neighber uses this same wood and doesn't seem to have a problem. But I have a Osburn 1800 insert and she has a huge stand alone oven. Does that make a difference?
