Ordinarily I burn a load or two in the evening for a little warmth and mood. Today (being a Saturday) I thought I would try ot run it all day without reloading it every 2 hours. I packed it full, let it char the logs a bit, then closed down the primary air control over the course of half an hour. Anything below 25% stops active flames. I thought I'd check out my chimney and see what kind of smoke I was getting (usually it is none). See attached. It looks pretty white to me, slow plumes of white smoke coming out. Do you think this type of smoke promotes creosote buildup? I can open the air supply to 50% and get adequate flames and near zero smoke but then I go through logs every 2 hours. I'm trying to get a project done out in my shop without actively tending the fire all day. The glass door lets me see that the bottom logs are glowing red on the bottom. No visible burning elsewhere and the firebox is fairly packed with an assortment of decent hardwoods.
