I built a cedar smoke house. My project progress is under My cedar smokehouse build under the smokehouse build thread. This thing isn't working like it should. Roaring fire in the firebox and only 85-100 in the smoke house. And it's not consistent. Seems like it's not drafting right. More smoke coming out of the stove door than the smoke house. Also, if I close the stove door, the fire dies fairly quickly. I am thinking that I didn't use a large enough diameter stove pipe. I have a 6 inch diameter pipe but it's an insulated pipe so only 4 inches is exposed. Any help would be greatly appreciated. Thanks
