You guys and gals that say your stove cruises along at 650 stove top temps, are you keeping your damper open a little (epa type stoves)? It seems if I get the top up to 650 I have to leave the air open 1/2 to 3/4 in order to keep it there. Is this true in your experience. I am using very dry maple splits packed about 3/4 full on a 2.3 cu in firebox Drolet Escape.
