No, you don't need a plumber to install a gas stove. You can do it yourself if you're comfortable with DIY projects. All you need is the right tools and a little bit of know-how. First, make sure that your gas line is properly installed by a professional. Then, follow the manufacturer's instructions to install your new stove. It should be pretty straightforward - just make sure that everything is securely attached and that all the connections are tight. If you have any questions, don't hesitate to ask a friend or family member for help. Good luck!

It depends on your local codes. In some cases, you may need a licensed plumber to install a gas stove, while in other cases it may be something that a qualified handyman can do. Be sure to check with your local building department to find out what is required in your area.
