Running my new Harman P35i insert on day 3. I'm burning Barefoots; I have an OAK. The installer did not do the draft test because he didn't have the tool, but will come back next week. Anyways, I get a good flame but my pellets are not near the 1 inch front of the burn pot. That is, they're burning well with a high, clear flame about 3 inches from the front -- further down the neck of the pot. Should I be concerned I'm not getting the best efficiency from the stove? I can't find anything in the manual that will help me. Is this a feed rate issue? Any help appreciated.
