With the charcoal insert and smoking device from Napoleon, you can transform your Napoleon gas grills into a charcoal grill and smoker. Enjoy the aroma of charcoal with your favorite smoking chips directly from your gas grill. Simply remove the grill grates and flame tamers, place the charcoal tray on the burners, add charcoal, and reinsert the grill grates. Heat the burners until the charcoal glows red. Then turn off the burners and grill the modern way with charcoal.
