And turbulence is bad why? How long have you been running this stove? What does your draft measure at compared to what is specified?Right. Because with the normal lever of air, the fire always has turbulence, (in my case) with normal damper I don't solve, with this valve under the stove the fire is more peaceful, of course I'm monitoring the flue and stove temperatures. Other than that, it seems like I don't have to constantly adjust air, the fire begins to grow but never with turbulence, and the draft starts to decrease automatically after the flames are exhausted, moreover, even with the wind, I have no turbulence
