Hi Y'all, newbie here. I have read several discussions on people smoking different items at temperatures between 200 and 250 but my question is how do you get smoke at this higher temperatures? Once I set the grill temperature out of the S setting, the smoking seems to quit and all I get is heat. I've been smoking a 4.5 lb brisket flat for an hour and 15 minutes, in the grill section and the grill temperature is only 164 and the internal meat temperature is 147. Do I just smoke for 2 to 3 hours then raise the grill temperature and forget about smoke?
