New member here so it might take a while to get the hang of this thing. I got a Regency I3100 insert new this winter and have been very careful about buring it. So far so good but this morning (5 am) I loaded it up and opened the damper all the way, closed the door and forgot to close the damper before I went to work. So it ran all morning with the damper wide open. I called the wife who was gone to take the kids to school and ask her to check it for me. She did around 10:00 am and said there were some red coals in a semi-log shape that broke apart when she reloaded it. My question is did I overfire it? I got a 32 foot 6" ss liner from stove to top of chimney with a cap. There is a plate welded right inside the door that hangs down about 1 1/4 inch, it runs from one side to the other and it was warpped ever so slightly. the tubes look fine and I can't see any visible signs of bent metal anywhere else. What do you think?
