Right now I am trying to cure my new double barrel smoker and I am having a problem. The fire. I am having a hard time getting enough air to the fire. I am having to open up the bottom dampaner to get enough air in. I am just wondering am I trying to make the fire to large? I have about 4 logs in there. When I close the dampaner on the door I get a lower temp and more of a white smoke. When I open the door to let more air in I get more of a blue smoke. Thanks for any help on this. It took me a little to get lump coal down now I am having to learn all over again. This is the first time I am using wood for the main fuel.
