Welcome aboard, Newbie. I'm with Oldschool on this one. You have too much fan and are blowing your ash out of the pot. Try reducing the air gradually, a half point at a time, and wait and watch for a few hours until you find the sweet spot. Reduce the feed commensurately if needed to keep the fire going. There's info here in the WIKI on trim pot adjustment.

Also, pardon the stupid question, but your fuel switch is set to wood, right?
Once you get the hang of it, you'll like your stove.
