Fired up the bull the first time with a small handful of pellets in the fire box and more in the hopper and did the burn-in @ 400F for an hour. During this time I saw no smoke. After I ran the power down I pulled the guts and looked in the firebox and there were pellets in there but also some ash. Not considerable...maybe a tablespoon or two. How would I know if I had a problem in this scenario. I did not smell any discernible smoke but did smell maybe a whisper of smoke along with probably some of the new grill smell. I'm planning a cook in two or three days but don't want to just use the grill as an oven. The directions say I should see smoke but I saw nothing. Any thoughts? Thanks for any comments.
