Do NOT use this cooktop as space heater to warm a room, as this
may cause carbon monoxide poisoning and overheating the cooktop.
Never cover the rack completely with materials like aluminum foil or
any other flammable objects. Doing this can cause an air flow block;
carbon monoxide poisoning, fire, or explosions may occur as a result.
