This would give everything in the ash pan 12 hours to cool. Fly ash will not be traveling on hot therms. And no hot coals to handle. Ash pan will be much cooler in general. In other words, come tending time, the very first thing you do is empty the ash pan.
Thanks! There are times when the shaken down ash is very close to the grates in my stove, which is why I tend to want to remove the ash immediately. To each his own.

The manual pipe damper in the stove restricts the size of the exhaust flue by about 75% in terms of area. In other words, even if the MPD is pushed all the way in, there is still an opening for exhaust that is about 25% of full open.
There is a great deal of controversy here about MPD's. Since we have fireplace insert stoves, this would make it very difficult to use a barometric damper. In this situation, the MPD is very useful. Whether or not you open or close depends upon what you're doing at the time. You should open it when you want to maximize airflow through the coalbed/stove, and close it when you want to minimize that flow.
Here is how I use it.
1) I open
the MPD (and open the ash pan door) completely when I am trying to liven the fire before shakedown
, or if I'm trying to get new coal to catch fire
. I also keep it entirely opened when I am shaking the grates
, when I want as much airflow through the stove as possible to suck fly ash up the chimney.
2) I close
the MPD after new coal has caught fire well
, and leave it closed until I'm ready to shakedown again 12 or so hours later. Closing the MPD tends to minimize airflow through the stove and retain heat in the stove, rather than going up the chimney. If, during an established burn, I need to increase airflow through the coalbed/stove, I do so only by increasing the size of the ash pan vent holes, not through any adjustment of the MPD.
Some people leave the MPD closed throughout the whole process. But one other reason I leave it completely open until new coal catches fire is to reduce the amount of potentially explosive gases retained in the stove. If that gas is not burning yet, I would rather it be drawn up the chimney than retained in the stove, serving as a potential fuel source for an explosion, or "puff back”. Of course, during reload, leaving an area of active fire uncovered from fresh coal until the new coal catches fire will greatly lessen the chances of an explosion, probably even if you leave the MPD closed. Once the fresh coal catches, one scoopful will fill in that area.
