Convert a propane grill to natural gas

I converted my propane gas grill to natural gas and I’ve never looked back. I didn’t base the decision on cost. I did it so I’d never run out of fuel in the middle of a barbecue. If that sounds like a winning strategy, check to see if you can convert yours.

First, contact the grill manufacturer to see if it offers a conversion kit for your model (some companies refuse to sell conversion kits). The conversion kit includes new gas jets, a flexible gas hose, quick-disconnect gas fittings and gas valve limiter stops. If you can get a conversion kit for yours, great. If not, you’re out of luck. Do NOT follow the “jet-drilling” instructions on the Internet. It’s just plain dangerous.

Next, check with your local plumbing inspector to see if you’ll be allowed to use flexible gas hoses. Some inspectors require a more permanent installation.

If you’re good to go, run a gas line to the grill and install a shutoff valve at the end of the run. Secure the valve to either the building or your deck, according to local code. Then install the quick-disconnect fitting that comes with the conversion kit. Remove the grates and burner assemblies and change out the jets (Photo 1). Install the limiter stop (Photo 2). Finally, remove the propane pressure regulator and hose and install the new hose.

Buy a Conversion Kit

You’ll save money by buying a complete conversion kit rather than buying the parts separately.

You’ll probably need tools to extend the existing natural gas line, usually pipe wrenches or adjustable wrenches.
