Just got the smoke vault 24" and I'm having a bit of problem getting it to actually make smoke. I've put in some soaked wood chips and then some non soaked wood chunks. If I crank it to high it'll billow smoke for a while but if I turn it down to low I get nothin. Any idea's? Is it possible it just wasn't enough chips? I didn't put much in because I was just seasoning it not actually cooking. Any help would be great.
