I have the old style Weber Genesis (with 2 rows of "flavorizer" bars). Last
year, I bought the Weber Steam 'N Chips smoker accessory. I've had little
luck, except at pretty high temperatures (350 +) in getting the thing to
emit ANY smoke. And 350 is way higher than the low temp cooking I'm
gravitating towards.

Weber's Hotline advisors have told me everything from "soak the wood chips
in water before putting them in the smoker box," to "don't soak the chips at
all." Neither seems to work at low temps (below 300).

Any suggestions would be appreciated.
