Like others indicated, you have to light the pilot, then it ignites the oven burner as needed for temperature settings. To prevent gas leaking when the pilot is not lit, there is a thermocouple that allows the pilot gas to flow only when it us warm from the pilot light being on. You have to hold the lighter on the pilot until it gets warm enough to allow gas flow and then it's will light and stay on.
