Here's a pic of my fire pot after about 8 hours of burning....no ash in the pot! With everything else I've tried so far there would have been ash build up right to the end of the pot. Unfortunately I didn't start with a clean ash pan so I don't know how much is blown into there but I assume most of it is going up the chimney.
