If you are burning wood and/or charcoal, you can adjust the temperature by adding more or less wood/charcoal. It is much easier to control the temperature with the (optional add-on) propane burner because it has a dial you can turn to adjust the flame. These multi-fuel ovens are not like indoor ovens. There is no dial to change the temperatures. The temperature is dependent upon the type of fuel you use. We’ve used wood and charcoal. Charcoal keeps an even temperature. If you want a burst of heat, add small pieces of wood such as oak. The chimney also helps with adjusting the temperature. If the chimney is fully open, you will raise the temperature. We also strongly recommend using an infrared thermometer to know the exact temperature of the oven and the stone. It will probably take some practice before you can bake the perfect pizza. The trick is to keep rotating the pizza 90 degrees every 15 seconds.  Check our article on 9 Tactics for Ooni ovens for more tricks and tips.
