My sister just bought a big old Victorian. Her chimney inspector told her not to burn a duralog in the living room fireplace. Instead he said to build a small fire with wood and add to it. I'm thinking this was said to "force" her to warm the chimney up with a small fire. It seems to me she could warm the chimney with a section of newspaper and then light a duralog. I don't have a whole lot of confidence in their ability to get a fire going and she is too far away for me to go over and do it myself. Can anyone explain what the reasoning would be behind NOT using a duralog?
