I watched every video I could find on the Amazing Tube Smoker before I ended up purchasing one, and everyone seems to put their smoker on the grill grates. I wasn't getting very good smoke dispersion when I did this, so on my last cook I actually lit the Tube Smoker underneath the heat shield. Once it was burning good, I fired up the grill and put the internals back inside. Wow, awesome smoke dispersion through the smoker. I haven't seen or heard of anyone doing this, but it works great and can't believe I am the first person to think of this.
