Hello all I have a little avalon pedelton insert. This was my first year burning and fir the most part I only would burn one load a night. Never really burned all day. Well now that I'm at home I have been burning all day and I noticed a few things. I let the first load burn down and almost all coals gone before I relaod. Once its lit it burns good up until I open the door to shift a log or something like that then I turns into a rapid out gas inferno.what am.i doing wrong
