what is recommended setting? finally starting to get tanks warm (just in time for the end of the heating season!) so i have been playing around with some fires. making adjustments to the air settings doesnt seem to change anything. i am burning 18-20% MC oak with 20-22% ash and maple. flame is really kicking ( i think? see pic, in actuality it is slightly more blue in color) and i am happy with it but i was just curious how everybody else manages air control. stack temp about 200-225C. 12' of 6" vertical class A. have all the turbs in. 55F water coming from storage, 160F water going back to storage. just got the temp gauge at the bottom of the tanks to jump to 135 last night. lot of water and steel to get warm. thanks!
