Using this Nella conveyor oven is easy. First, plug it into a 240V/60 Hz power source with the 6 - 20P plug. Then, set your desired temperature within the range of 70 - 260°C / 158 - 500°F using the adjustable top and bottom heat controls. You can also adjust the conveyor speed according to your needs with the variable speed control. Place your food, like bread, bagels, or pizza, on the 14-inch conveyor belt and let the infrared heaters do their job. Remember to keep the oven in a well - ventilated area, even though it's ventless. When cleaning, use a soft, damp cloth to wipe the stainless - steel surface. Avoid using abrasive cleaners that could scratch the surface. Periodically check the conveyor belt for any signs of wear and tear. If you notice any issues, stop using the oven and contact customer service.
