My food has been tasting good but my chunks are burning too fast (I think) or too hot. I am using the Brinkmann Gourmet Electric smoker. When I'm done smoking my chunks are all white ash. Is this normal? Also, I recently opened the top and they were on fire in the bottom. I usually place them in the bottom right on the lava rocks beside the element. ANY help would be greatly appreciated. I'm smoking for the family tomorrow!
