You may use dry or pre-soaked wood chips in your smoker. Dry chips will burn faster and produce more intense smoke. Chips pre-soaked in water (for approximately 30 minutes) will burn slower and produce a less intense smoke.
No. Masterbuilt smokers are not designed to be used with natural gas. Our gas smokers are designed for propane use only.
