Hello Outlet,
This gas range only needs a standard 120V outlet, and a 15-amp or 20-amp circuit will work.
Your current 20-amp setup is perfectly fine, no need to increase it.
If you’re moving the outlet lower, just keep the same setup and make sure it’s a grounded 3-prong outlet.
For safety and to meet local codes, we highly recommend having a licensed electrician or professional installer handle the outlet relocation.
Here’s the Installation Guide: (Page 16)

Delighted to have you as part of the Samsung family.
