Always had a little dirty glass on the lower left corner of my insert,didn`t really think anything of it. Sat. morning closed the door, and I could pull five one dollar bills out easily. The bracket that the door latch fastens to had come down about a quarter inch. (maybe a large piece of wood dropped on it,, don`t know.) Well I fixed it,nice and tight now. Figure that my inattention has probably cost me an extra cord of wood up to this date. I say this because of the longer burn time the past 2 days,just a totally different fire. Live And Learn!!
