I own a breckwell p23. 4 times this winter I have looked over and noticed my flame went out and smoke is pouring into my house. I have to open up windows and turn fans in. It happened tonight and I'm not sure why it happens. Happened last weekend and then today. Both the blowers work. Barely any soot on the glass and was running fine today for 5hrs and then smoke came pouring in. I had it in 3 and damper was a good ways out and flame was good. Ran fine until about 10pm. I'm not sure what it is. I just fully cleaned the stove behind the small doors and the outside vent pipe.
