im still trying to fine tune my burning habits in my lopi freedom insert. im trying to burn down my coals and bring my stove temp down before a reload. ive been bringing my coals to the front and opening the air control all the way. im getting an extra hour or so heat off the coals. seems to be working. my question is, should i open the draft control all the way too?? or would that burn up the coals to quick??
