Should the supplied air vent be placed with a cooker?

With a gas-ventilated oven, the air vent should always be placed. This ensures that the burner in the oven receives sufficient oxygen and the surface will not go out during use. With an electric oven, we also recommend installing the air vent. This is because this air vent can provide extra protection when using larger pans in front of the burners. This prevents any discolouration on the back wall.
