Thanks Guys. The dealer sent the installers out to check on the stove. They went over everything - the stove is exactly what it should be. Damper closes as it should and that was a concern of mine. They looked at the wood and thought is wasn't as good as it could be….not too wet…too small! I hand split a bunch of wood because I wanted it to dry out. I don't know. I added 1 bio brick to the stove wand it didn't do much. I guess i will try 2 bricks. They noticed a draft in the stove room, and this might have an effect. I would write more, but I'm off to find a draft.
