Reply to "Fire in the Hole"

This past weekend I watched flames from my firepot ignite the pellets in the front of my auger tube. I had the door open for an extended period of time when it happened. I think the key is to keep the door shut. What's happening is the temperature is dropping so the pellets keep dropping into the firepot. This makes the fire bigger which eventually gets tall enough to reach the auger tube and the fan, for some reason, blows the flame back into the tube.

It could just be timing too, say the temperuture in the cooker is dropping so the pellets are being added at a faster rate so the fire is getting bigger, maybe even to the point where it's now overshot the temp a bit, so you already have a decent size flame in there. Then you open the door, what's going to happen?, temp is going to drop, and more pellets are going to be added to make an even bigger flame, that is now getting all the oxygen it wants.

A Simple solution to stop this would be a small square of steel tacked vertically 1/4 to 1/2 way down the ramp, I would think.

Or keep the door shut.
