I just bought it used and am new to smoking. I finally found the instruction manual online but am confused about something. It has both a SMOKE mode and a COOK mode. I thought the smoke was supposed to come from the pellets while cooking so that's my first confusion. I'm able to set the temperature on cook mode but not smoke mode, although there is a button while in smoke mode to set the smoke amount, which also apparently causes the smoking (their words) temperature to be 165-195degrees depending on desired smoke level. How do you use this? A butt would never get done at those temperatures would it and it would take a loooong time too, wouldn't it? Or is it for some meats that have a lower finished temperature than a pork butt? The instructions don't explain why to use this/give suggestions and I can't find a phone number or email address to contact Expert Grill. TIA.
