Initial Seasoning Process
Before cooking food, the smoker must be seasoned. This process burns off any manufacturing oils and prepares the interior for optimal performance. Refer to the detailed instructions in your product manual for specific temperature and duration settings for seasoning.

Side Wood Chip Loading System
The patented side wood chip loading system allows you to add wood chips without opening the smoker door, maintaining consistent temperature and smoke. Fill the loader with your desired wood chips (e.g., hickory, cherry, mesquite) and insert it into the side of the smoker. Push the handle to drop chips onto the heating element.

Water Pan & Smoking Racks
Fill the water pan with water to add moisture to your smoked foods, preventing them from drying out. The smoker includes four chrome-coated smoking racks, providing ample space for various meats and vegetables. The interior light illuminates food in low light conditions when the door is open.

Maintenance & Cleaning
Regular cleaning ensures the longevity and optimal performance of your smoker. The drip tray and water pan should be emptied and cleaned after each use to prevent grease buildup. The chrome-coated racks are removable for easy cleaning.

Troubleshooting
Bluetooth Connectivity Issues
If experiencing issues with Bluetooth connectivity, ensure your smart device is within range of the smoker. Some users have reported needing to power cycle the smoker (turn off, unplug, wait 5 seconds, plug in, turn on) and re-pair with the app. Ensure the app is updated to the latest version.
Temperature Discrepancies
While the internal thermometer is generally accurate, external probes can be used for verification. Some users note slight discrepancies during the warm-up phase, which typically stabilize once the target temperature is reached. Ensure the meat probe is correctly inserted into the thickest part of the meat, avoiding bone.
