All gas ranges come from the manufacturer set up to burn Natural Gas (NG). If you’re set up to burn Liquid Propane (LP) in your house, you’ll need to convert the range for this. Most gas ranges come with instructions for doing this but sometimes they get lost or “borrowed” by a sticky-fingered tech who worked on your range.
These instructions below are for a Frigidaire gas range, FPDF4085KF, but the same idea applies to all gas ranges. If you have some other model, you can use this as a guide for the general concept of converting your gas range to burn a different fuel.
