Ok 13 is running right now stove top about 550 with air control out about 1/8. We had air control open she went up to about 720 and shut the air dropped down to 650 within a min. Man did I have some secondaries when I pushed the air in at 720. Stove works great. Any tips for a longer burn are greatly appreciated. I get about 5-6 hours although I did load up at 7 am and came home at 630pm stirred around my ash put some kindling and she lit right up
