Not if you are going to fill it up. I had some success just filling the outside rows and lighting both ends - side by side the pellets get too hot and burn thru to the next row
In my 6X8 I could get almost 2.5 hours per row - sometimes more sometimes less. The issue is that the older ones are not vented in the same manner as the Pellet version and don't get as much air. A lot depends on how much ventelation you get inside your smoker.
