I had something happen earlier that is new for me. I lit my stove up as usual and a few minutes later a bunch of smoke started pouring out of the top eyelets into the room. I immediately checked to make sure I had everything opened up and I did. I then quickly closed the air regulator and reopened it. I kept an eye on it and everything corrected itself. Could it be I just had no draft and a smoldering start up that didn't make enought heat to start the draft?
