What is the top end cruising temp on these? This is my 3rd season with this beast. 1st year was typical learning, got seasoned wood that was not, bad draft through clay chimney. 2nd season, wood was dryer, SS insulated liner installed, stove would cruise ~450 to 475. 3rd season, wood is really dry, over 1 1/2 years out in backyard, in direct sun all summer (for 2 summers). What a difference, the beast has now been cruising ~550 and wants to creep up to 600, never really had secondaries before, now they last along time and boy does that jack the stove top temp up. There is definitely something to be said for truly dry wood.
