The Cookshack 24 Inch Charbroiler is wood pellet fired and adds smoked flavor to steaks, chops, chicken breasts and grilled salmon, while giving you the temperature control of a gas fired broiler. The double wall construction is insulated with 850 degree F Spin-Glas. The two cast iron grates weigh 30 lbs each and provide 480 square inches of total cooking space. Cookshack CB024 Charbroiler is designed to give the wood-grilled flavor people love featuring an electronically controlled pellet-cooking system. The system is fueled by 100% food-grade wood pellets that are introduced into its fire-pot by an auger requiring a small amount of electricity to operate. Food tastes fabulous when cooked over pellet smoke!
