Experts and people far smarter that me...Please help. I am working on a cold smoker built from a Cres-Cor proofing cabinet. Everything has worked exactly as I had hoped, except for one really important thing...I cannot get it to consistently draw air from the bottom and flow out of the stack on top. Here is a very basic rundown of my design:

1. Two 18 inch smoke tubes at the bottom
2. Two ball valves at the bottom as adjustable air intakes
3. One four inch stack with adjustable damper in the upper right corner.

The thing smokes beautifully and puts out a great product; it just is never consistent in the direction it draws air. Sometimes if draws from the stack and vents smoke from the ball valves, other times it does exactly the opposite. I cannot figure this out!!
