Here you go:
Call your gas company, many do it for free or a nominal fee as they don't want homeowners blowing themselves up because they made a mistake.
You need to hire a professional certified person to hook up gas to a house stove.
If you need to ask you need a pro. You can call your gas company and in most cases they do it for free. Or you can call a plumber. Maybe there is a handyman in your neighborhood.
Get a pro, you could void your homeowner's insurance if you do it yourself and blow up your house.
