I've used my AMNS in my MES for cold smoking a couple of times now. Some questions just occured to me. Should I leave the chip box in or take it out? How about the "round" thing used to put chips in? When it is in and turned, it does seal that area somewhat against smoke getting out. Should the AMNS be near the bottom or the top? I'd think near the bottom for smoke to rise -- but thought I'd ask anyhow. If using ice to keep cool, near the top or near the bottom? I'd think near the top since hot air rises and cold air falls. Any other hints for this configuration?
