❤️For best results, we recommend keeping the top vent nearly closed and allowing the Breezo fan to add the necessary air to maintain your desired temperature. Opening the top vent too much can lead to overshooting your target temperature, especially at lower temperatures used for smoking. For higher-temperature grilling, such as searing, you may open the vent slightly more to accommodate the increased airflow needs. These settings work well across various grill sizes.
