I bought a Masterbuilt 30" a few weeks ago and was getting a lot of creosote build-up, so I found some info here about mailbox mods and cold smoke pellet devices.
I found a few bits and pieces in my garage and bought a 12" tube.
I used a 24" length of 4" round duct with a 3" reducer with a crimped end which fits snugly into the wood chip filler hole. I just light the pellet tube and stick it in the duct. I added some short legs to the tube by using sheet metal screws.
Works great. Burns about 4 hours, which is fine with me since I mostly smoke fish, shrimp, pork belly strips, popcorn and malt. Picture attached. Note the light smoke.
