The above is the end result of all of the recent advice given to me from all of you on this site. I stocked the stove 3/4 full at 11 AM. Cut the air back gradually until only about less than 1/4. Mostly oak and hickory and maple. Lets see how long my blower can stay on for. Im hoping for at least 5-6 hours. I have not been getting the burn times as most of you with similar stoves. Its a work in progress. Thanks all again.
