Smoke

[bqpig]

Just bought a 30'' MES gen 3, did the break in the other night. started smoking a 8lb lb B butt today. I don't see much if any smoke coming out the vent. vent I wide open. when I started it out I set it to 275 put some chips in to get it going then turned it to 225. when it first started at 275 it was smoking a lot. another question should the chips burn all gone or do they just get black a you need to dump them out during the cook? got 13 people coming over today don't want to f it up.

Thanks for the help
