I was observing my burn, when I noticed that my front secondary tube and the underside of my baffle were literally glowing red! Is this normal? My surface temperature was only 450 degrees, but my water kettle on top was at a rapid boil. I thought I read in the manual that no part of the stove was supposed to get red hot...Was it possible that I loaded the stove too high? Or maybe it got too hot, too fast? HELP!
