Before the oven is officially used, it should be baked at a high temperature to expel the odor of the heating of the new oven. Before using a clean damp cloth to wipe the oven inside and outside once, the oven door half open, the upper and lower fire will be turned on, the temperature is adjusted to the highest temperature (250 ℃) air bake 10 minutes.
After 10 minutes, you can open the door fully to accelerate the heat dissipation, and then you can use it according to the normal program. For smaller ovens, simply wipe the interior and exterior of the oven clean, preheat the oven with the door open (the same way you would for smoke or odors), and turn the power off when smoking. The heater will alternate between light and dark.
