Need Help. Started my first smoke about 45 mins ago and I can no longer see the smoke coming from the chimney. Im using a 44" Smoke Hollow which is a dual burner propane smoker. Running one burner/smoke box im sitting right at 240 to 250 degrees which im happy about however 45 mins passed and no more smoke! Im staying at temp but there is no smoke coming from the chimney. This is not normal im assuming? I switched to the other burner/smoke box and am at temp and have smoke again, not sure for how long. Im using apple.wood chunks and cooking ribs. Im looking for a 5 to 6 hour smoke at the 225 to 240 range. Anyway, is it normal to burn through the wood so fast? I did not soak the wood which I am doing now so hopefully that helps. Just checking to see if this is what to expect or im doing something wrong. Thanks and sorry for the long winded explanation, rather give too much information than not enough.
