Feeling the Heat
I had only used the ash door for a couple of minutes
Couple of minutes!?! I think you're lucky nothing worse happened. Someone mentioned a forge & that's exactly what these things are with the ashdoor open. I used to open mine for a max of 4-5 seconds just to get a flame started but beyond that it gets scary pretty quick. I won't even empty the ashpan without moving all the coals off the grate for the same reason.
