I've got a PE vista, its got a smaller firebox. I put what I believe to be a piece of oak (not big, bout 2x4 and 16 long) and some other piece of wood in for reloading. After a bit the stove is just over 600 on the Rutland thermometer. Air was down, and I've got newbie wood. How would I go about loading for the night, if that's happening with a small load? Tthanks!
