Holy Crap...Batman... my temp(stove top) got to 650 today... the installers said that I probably got ash stuck in between the trap door & the stove. So I'm watching my temp maintain 650 and wondering if it was going to come down or not. Took my ash pan out...tapped on the bottom of the trap door to make sure it was shut. Temp started going down...in all honesty...can't tell if it was going down cause I tapped on that door or the wood started to burn out on it's own... Whew! What really bothered me is is I just got this thing yesterday! The guy who installed it...the owner of the store said that temp is up there...but not to be alarmed yet!
