In a year of reading here, I've not seen this addressed, so here it is: You load the stove full on a good coal bed, and just as it really starts roaring, you're ready to start throttling back the air. Then it happens... the glass breaks, or the door latch fails, or your air control jams wide open... something that causes you to have no control over this now-raging inferno. You have no flue damper to close. What do you do? I figured this might be some handy info to have in the back pocket, for future reference.
