Planning an Outdoor Gas Line for a Grill or Fire Feature
What running gas out to a backyard grill or fire feature actually involves, and why it isn't a do-it-yourself project.

Running a gas line out to a grill or a fire feature sounds like a small project until you start planning it, at which point it becomes clear how many decisions are involved before anyone even picks up a wrench. Here's what's generally worth thinking through if you're considering an outdoor gas line for your backyard.
What the project generally involves
At a planning level, an outdoor gas line involves running a dedicated line from your existing gas supply out to the new fixture, whether that's a built-in grill, a fire pit, or another fire feature in the yard. That usually means deciding on a route for the line, accounting for how far it needs to travel, and figuring out how it will be protected once it's buried or run along an exterior wall.
Questions worth having answers to before you call
- Where exactly the grill or fire feature will be located
- How far that location is from your existing gas supply
- Whether the run will be underground, along a wall, or a combination
- What fuel your home already runs on, natural gas or propane
- Any gas appliances you plan to add later, and which ones
Why it's a licensed job
Gas work isn't a place to guess. A line that's sized wrong, routed poorly, or connected incorrectly is a safety issue, not just a performance one, which is why it's handled by licensed plumbers rather than treated as a general handyman project. At Martin McManus Plumbing & Heating, all work is completed to current code requirements and safety standards. If the grill is part of a bigger project, such as a new kitchen range or an extension of an existing line, mention every appliance when you call so all of the gas work can be planned together.
New lines, extensions, and finding existing leaks
Beyond new grill and fire feature installations, gas piping work can also mean extending an existing line, adding a hookup for a kitchen appliance like a gas stove or range, or finding and repairing a leak in a line that's already in the ground. Complete gas piping installations, gas lines for furnaces and boilers, and gas line extensions all fall under the same kind of planning as a grill line: figure out the run, size it correctly, and connect it to code. Any of those is worth having assessed by the same licensed team rather than treated as a separate problem.
What the process generally looks like
At a high level, a project like this tends to move through the same broad stages: someone looks at where the fixture will sit and where the existing gas supply is, a route gets planned between the two points, the line itself gets run and connected, and the whole thing gets checked before it's considered finished. Knowing that shape ahead of time makes it easier to have a productive conversation on the phone, since you can describe your yard and your goal instead of trying to guess at technical details yourself.
Thinking beyond just the grill
Once a gas line reaches the backyard, it's worth thinking about whether you want to plan for more than one fixture at the same time. A grill and a fire pit or other fire feature often get added separately, months or years apart, when planning both at once during the same project can mean less digging and disruption to the yard overall. It's a reasonable question to raise when you first call, even if you only want the grill hooked up right now.
