Update. Just wanted to let you gentlemen know, I finally got her STUFFED full of wood the other night. One BIG round, didn't measure, but lets just say I had to persuade it through the front opening . Another large round (crotch)a lil smaller than the first but wider. But these two ate up the width of the Summit. And I squeaked a wide flatter 1/4 round on top. Box was FULLLLLLL. LOL I got her up, shut the air down, and was good to go. Later, early morning, when the wood was all glowing, temp rose to about 700-maybe 750 at one point. But that lasted an hr I guess and then it leveled off about 600 maybe a tad lower. Glass although not sparkling clean, is getting cleaned by the hotter loads. The creosote formation where the door was leaking is staying fairly well clean. I will be cutting all my wood to 16" lengths for now on. Anything longer is too close to glass and fogging it up with lite buildup. I have her down pretty well, not fudging with the thermometer, not messing with the air intake, Just get her hot, cut her back, shut air down, let her burn. Check the temp once in a while. I have come to grips that when the load of wood hits the full glowing coal log stage, its going to spike up some, nothing like the high temps I had before. I can live with that, just wear less while sleeping thats all .
