Great unit so far. Fire last 8+ hours so far in 30°f weather. Only cons so far: Not a fan of the wing nuts on the ash pan and upper clean out doors. The Green light button is a bit confusing at times as it seems to indicate no heat when there is a small fire burning (and fan kicks on still when plenum has a call for it to kick on). But not a big deal. One fire brick has cracked but not Drolet’s fault I’d say.
