Hello all! i have a few questions... I was given an electric smoker, a medium sized can shaped one. I put it together and read the instructions but they are very vague on how the wood chips are used. there is the electric element in the bottom surrounded by lava rocks, and a water pan. Where do i put the chips? in an aluminum pie pan directly on the element, under the water pan? please enlighten the NewBie on how to get the smoker smokin' !
