You can maneuver your gas grill into place, but you cannot connect the grill to your gas source yourself. All municipalities mandate that a certified plumber carry out this work, so you’ll have to reach out to a plumber or a gas grill installation company in your area. Given how dangerous a gas leak can be, gas lines and connections are highly regulated, so you’ll need a professional’s help and a permit to install a gas grill.

On average, a gas grill can last from five to 15 years. The exact lifespan depends on several factors, including the brand and quality of the grill, frequency of use, and whether the gas line is buried or above ground. With proper maintenance and care, such as regular deep cleanings to remove food, grease, and carbon deposits, a grill's life can be extended. Protecting the grill from the elements with a cover can also prevent rust and reduce the need for repairs. Most grill manufacturers also offer extended warranties, which vary in coverage and terms.

A few potential problems can cause your gas grill to stop working:

• Burners aren’t properly aligned.

• Food debris is clogging the burners.

• Hose connections may be blocked.

• Burners may not be getting enough gas.

• Gas valve is not working properly. 

If you’re experiencing any of those problems with your gas grill, hire a local grill repair professional to inspect your grill for issues and implement a plan to resolve them.

While it’s possible to repair minor grill issues like replacing a burner, more serious issues are clear indicators that you need to replace the entire unit. A few signs that your gas grill may be at the end of its life span and it’s time to consider replacing it include:

• Rusty or cracked firebox

• Weak, yellow, or uneven flames 

• Flaking, cracking grates 

• Leaking or cracked propane hoses 

• Failing igniter 

• Heavy buildup of grease
