So, this'll be the first full season with the 30, and I THINK I've gotten the hang of it. Boy, she sure does love that dry wood... one improperly-seasoned split and the cops show up to the party. Anyhow, the question is this: the photos show my 30- - packed full with 2-year seasoned BL - primary air shut down fully - outside temp about 45 or so. I hope the photos show that there is no visible flame, in that I can't "see" the wood burning, but there are very active secondaries filling the entire top of the firebox. What I can see is a jet of air coming from the doghouse straight to the back of the box that looks like a blowtorch is attached to the doghouse. There is no visible smoke coming from my chimney. So, the questions are: - Is this normal? We're certainly warm... am I doing it right? - Mrs. Blue is concerned that the primary is completely closed, insisting we'll choke down the fire and smolder ourselves to death. Yes/no?
