Revolutionary Technology


One of the challenges with traditional propane smoking is the need to monitor the temperature and adjust the flame as needed, so you don't over or undercook your food.  With the ThermoTemp smoker, you add your food, set the temperature, and walk away. Our patent pending technology adjusts the flame to maintain consistent temperature, for delicious results every time.

  • What is the best way to clean my smoker?

    When cleaning your smoker, use 50/50 hot water and apple cider vinegar in a spray bottle and shake well. Use a soft sponge. It is very important not to use harsh chemicals to clean your smoker.

  • How do I pre-season my propane smoker before using it for the first time?

    Curing your smoker will rid the unit of manufacturing oils, allowing them to burn off. Pre-season your smoker prior to first use.

    1. Perform soapy water test:
    2. Using a napkin or cloth, rub a light coat of cooking oil on smoker racks and inside smoker door. Make sure water pan is in place with NO WATER.
    3. Fill wood chip tray with up to 1 cup of wood chips and light your smoker. Close door.
    4. Let the smoker burn for about 1 hour. Make sure temperature reaches 350°F (177°C).
    5. Allow unit to cool completely.
    6. Reapply light coat of cooking oil on smoker racks and inside of smoker door.
    7. Re-light smoker and burn for 20 minutes.

    * Cure your smoker periodically to prevent excessive rust.

  • Can I use natural gas instead of LP for my gas smoker?

    No. Masterbuilt smokers are not designed to be used with natural gas. Our gas smokers are designed for propane use only.
