Finally installed it this weekend. Break-ins were uneventful, house smelled like curing paint, CAT was active for 4 hours on the last fire. Burn times are impressive so far, with about half the load still going after 12 hrs., but the heat doesn't seem to be there. Fans are on med./high, T-stat at 2-2.5 or so, CAT is active and in the upper 1/3rd. on the guage. Just not putting out the heat I was hoping for. I've played with the T-stat to see if I might have a reverse wound spring, but it seems to work like it should. Wood is last years split Pine, so moisture content shouldn't be a factor. Compared to the Timberline, this thing is pretty anemic. Am I expecting too much? Suggestions? Thanks, JB
