just as the title says, an adventure ends, I've tried everything, it seems impossible, despite the draft of the stove, and the air exchange, to have an impeccable air quality, I should accept 6-10 ppm carbon monoxide (without cooking) I think that the heat, the fire, expands, and somehow, comes out in small doses from the joints of jotul, maybe a steel stove is better because it has fewer joints, anyway. Maybe I'll sell this piece of cast iron or put a fire effect lamp inside, with some pieces of wood! Thanks for all the support provided.
