A:Answer Greetings!
Thank you for reaching out and we hope you are in good health. We appreciate your interest in Samsung home appliances, specifically with Samsung - 5.8 Cu. Ft. Freestanding Gas Convection Range with Self-High Heat Cleaning - Black stainless steel.
All ranges are setup for natural gas at our factories. For your range to utilize LP gas, the installer must replace the 5 surface burner orifices and 2 oven orifices with the provided LP orifice set, and reverse the GPR adapter.
I have shared the installation guide below. Please access the guide and turn to page 18 for gas requirements.
