Rosso and Gusto units must go through a seasoning process before being used for the first time, or you’ll risk damaging the powder coat paint on the oven. To do this, simply build a small fire and slowly add larger pieces of wood to bring the oven to at least 500 degrees. Don’t exceed 600 degrees and let the fire burn for about two hours before cooling completely. Also keep in mind that wood-fired ovens require more attention than gas-fueled alternatives.
