Does anyone know if you need Battery power for Refrig...

Hi
Does anyone know if you need any power if you have the refrig set for Gas. We have our unit sitting without any power and the battery is not connected so that it will not draw down. We want to turn on the fridge the day before we get ready to head out and were wondering if we need to have the battery on or if it strictly runs on the gas for power. If it does need the battery does any one know if it draws much?
