Hi David. If this works, here is a link to a thread I started about it.

Currently, I put in some hickory chunks I got from Amazon after foiling a good portion of the smoker box as has been suggested elsewhere. Also, set the temp for 150 for .7 hours (whatever that works out to, since I suck at math) and then to go to 225 for a total of 4 hours. The first .7 hours, it smoked really nice. Had what appeared to be thin blue smoke to thin white smoke. Then I couldn't see any smoke at all just before the .7 hours ended and it ramped up the temp, going to 225. It has now been "puking out" thick white/grey smoke for the last 20 minutes or so. Pretty sure the chunks caught fire. This does not make me want to put any meat in there as expensive as it is. Everyone says there is a learning curve to these things, but I may end up just using my AMNPS.
