Hey Im hoping theirs a Regency guru on here! We have been burning with the F2400 for a little over a month now. I feel like I have the thing pretty dialed in but every now and then it does some funny things. My biggest question is what is a comfortable stove top temp? When I do a full load it seems I can get the stove top well into 600-700 very quickly and as I am cutting the air back there seems to be a big difference from 75% open and 50-25% open. What I mean is at 75% open I have a very robust fire and temps rocking around 700 but when I cut it back to 50% open a lot of times the secondaries stay lit for a few minutes then go out. They will come back but it can take 10-15 mins all with a smokin chimney. I repeat this back and forth till finally I have the air closed, and secondaries burning before I am ready for bed. Im thinking maybe I need to let it cruise hard at 700 at 75% open for a while before I start closing. But I worry about an overfire and thats why I start to cut it back. The dealer said load, bring to temp, then close the air all the way. If I do that secondaries are done in a few minutes. Need some help here!!
