A magnet sticks to the ash door and can block the air nicely. I don't want it to suck to hard could it break the glass with a lot of draft??
Is 350 -400 to warm is that what you mean buy YOU SHOULD BE ABLE TO COOL YOUR FIRE DOWN MORE
Have you replaced the Gaskets on both doors If it is getting Air in with all of the air vents blocked then either The door's gaskets are no good or The doors or warped or you might have a crack in the stove some where First replace the door's gaskets That might be your problem if it works Then I would use the second dairy air source that is what you are blocking
off in the back it is a Bi Metal Thermostat You would set that so when the fire starts to die down it would open to let more air in to help keep the fire going with that set right you should get much longer burn time with a full load of coal
