Thanks for the answers. I don't get smoke in the house. Normally get no smell at all. The fire had been going for a couple hours and it was very hot.

It was just this one piece that produced that smell.

After that piece burned for a while, it quit producing a smell. It's not that cold out so that was the last piece of wood I used for the night. I'm gonna use some wood out of that same cord tonight and see what happens.

Oh, and it was cleaned at the end of last season and this is only about one week into using it.
