I have never raked the coals, so maybe that has been my issue. I have always just placed the new splits right on top, with an alternating pattern for staking them. The wood has never hissed/bubbled out or anything to indicate that it wasn't dry. I do have an outside air kit. And I've always opened the air up all the way on reload. I have about 1/3 of the wood from my neighbor left, so I need to get some new wood as even now with most of the wood around here being oak, it probably won't be dry for this next winter.
