How to Convert a Wood-Burning Fire Pit to Gas

You've got a fire pit you love—maybe it's built into your patio, maybe it's a stone ring with a grate. But every time you use it, you're dealing with smoke, ashes, cleanup that takes forever, and the constant battle against wind killing your fire. You're thinking: what if I could have all the ambiance with none of the hassle?

Gas conversion is absolutely possible. I've retrofitted dozens of existing wood-burning pits into clean, easy-to-use gas features. It's one of the best upgrades you can make if you love fire but hate the maintenance.

Let's walk through how it works, what it costs, and what you need to know before you commit.

Why Convert to Gas: The Real Reasons

Before we get into the how, let's talk about the why—because conversion isn't always the right choice, and you should understand what you're getting.

You get convenience. Push a button, flame appears. No gathering wood, no fighting with starter kindling, no waiting for coals. You want fire on demand; gas delivers that.

You lose the wood smell. Some people consider this a loss. I'm realistic: if you love the smell of real wood smoke, gas conversion might feel like a compromise. You get clean, smoke-free flame in exchange.

You reduce smoke and emissions. If you live in an area with air quality concerns or burn bans, gas is the future-proof choice. No smoke means no regulatory issues.

You simplify cleanup. No ashes to spread across the patio, no soot on furniture nearby, no residual smoke smell in your clothes. Your outdoor space stays cleaner.

You improve safety in some ways, complicate it in others. Gas doesn't throw embers. Gas also requires a gas line and demands respect for a different set of hazards. Net safety benefit depends on your specific situation.

If you use your fire pit 3+ times a week, gas conversion is probably worth it. If you use it occasionally and love the traditional experience, keep it wood-burning. If you're somewhere in the middle, gas is usually the practical winner.

Conversion Kits: What You're Actually Installing

A gas conversion kit is essentially a complete burner assembly that fits inside your existing fire pit enclosure. It includes:

The burner itself: A metal grate or ring with multiple ports or a linear flame presentation. The burner is where the gas ignites and creates the visible flame.

Gas inlet assembly: The connection point where your gas line attaches. This is usually a 3/8-inch female adapter sized for your fuel type.

Ignition system: Piezo ignition (manual button), electronic ignition (push and hold), or manual (match or lighter). Most modern kits use electronic ignition—reliable and easy.

Control valve: Allows you to adjust flame height and shut off the gas. The control might be manual (twist knob) or equipped with a remote control for convenience.

Decorative media: Glass beads, lava rock, ceramic logs, or stones that sit on or around the burner. These conceal the burner and radiate heat.

Premium kits like those from Summerset, Fire Magic, and Blaze include thoughtfully designed burners with even flame distribution and aesthetics that actually look intentional in your pit. Budget kits exist but often produce uneven flame and feel obviously retrofitted.

Kit Sizing and Compatibility

Conversion kits aren't universal. You need to match the kit to your pit's dimensions:

Pit diameter or length: A kit designed for a 24-inch diameter pit won't work well in a 36-inch pit. The flame will look small and off-center. Get the dimensions of your pit opening and choose a kit rated for that size.

Pit depth: Some kits need a minimum depth to sit properly and allow heat dissipation. Shallow pits may not accommodate standard kits. Check the kit specs against your pit design.

Existing grate or structure: If you have an existing metal grate or structure inside the pit, the kit needs to work with or replace it. Some conversions mean removing everything and starting fresh.

Measure your pit carefully. Take photos. Get the exact dimensions. When you contact us or a manufacturer, provide these details so we can recommend a kit that actually fits.

Gas Supply: Natural Gas vs. Propane

This is the decision that determines your installation complexity and long-term convenience.

Natural Gas Conversion

Natural gas means running a line from your home's gas meter or an interior gas line to the pit location. This is a permanent installation that requires permits and professional installation.

Advantages: Unlimited fuel. No tank management, no refills, no storage. Lowest long-term operating cost. Most reliable fuel source.

Disadvantages: Professional installation required (and that's not cheap). Permits and inspection necessary. Digging and running line costs money—potentially $500-2000+ depending on distance and site conditions. Not reversible—you're committing to this installation.

Good fit: You're doing a major patio renovation anyway. Your pit is close to the house or existing gas infrastructure. You plan to stay in your home for years.

Propane Conversion

Propane uses a tank connection, just like a grill. You place a standard 20-pound propane tank nearby (or smaller portable canisters), connect the kit to the tank with a regulator and line, and you're done.

Advantages: Simple installation—no digging, no permits, no professional needed (though having a professional verify the connection is smart). Portable—you can move the setup if you rearrange your patio. Easy fuel: propane is available everywhere. No long-term infrastructure commitment.

Disadvantages: Tank management—you need to monitor propane levels and arrange refills. Tank visibility (you're managing a large cylinder in your outdoor space). Higher long-term fuel costs compared to natural gas, though still economical.

Good fit: You want simplicity. You're renting or might relocate. You don't have gas infrastructure nearby. You want to try gas before committing to permanent installation.

Conversion Kit Specifications: Fuel Type

Here's the important detail: many kits work with either fuel, but the burner orifice (the opening where gas enters) is different for propane vs. natural gas. The molecular properties mean propane and natural gas flow differently.

When you order a kit, you specify your fuel type. The manufacturer sets it up with the correct orifice. If you order a natural gas kit and try to use propane, the burner won't perform correctly—either too much or too little flame. Order the right fuel type from the start.

Installation: What's Actually Involved

This varies significantly based on fuel choice, kit complexity, and your pit design. Let me walk through a typical propane conversion (simpler) and a natural gas setup (more involved).

Propane Conversion Installation

Here's a basic process for retrofitting an existing wood-burning pit with a propane conversion kit:

Step 1: Clean and prepare the pit. Remove any remaining wood, ash, and debris. Clean the pit interior thoroughly. You want a clean base for the new burner.

Step 2: Position the burner kit. Center the kit in the pit. Ensure it's level—this matters for proper flame distribution. If your pit has an existing grate, you might remove it or position the kit on top of it depending on the kit design.

Step 3: Connect the gas line. Run the propane hose from the tank to the gas inlet on the burner. Use proper fittings and a regulator rated for your kit's BTU output. Check for leaks using soapy water—bubbles indicate a leak. Tighten connections if you see bubbles.

Step 4: Test the ignition and flame. Turn on the tank valve, press the ignition button, and test the flame. Check that ignition is reliable, flame is even, and the control valve adjusts flame height properly.

Step 5: Add decorative media. Place your chosen media (glass, lava rock, ceramic logs) around and on the burner grate. This conceals the burner and improves the aesthetic. Make sure media doesn't block the flame or airflow.

Step 6: Run a final test. Let it run for a few minutes, check for any irregularities, ensure safety controls work.

Total time: 2-4 hours for an experienced person. Cost: kit ($200-800) plus propane ($50-100 for initial fill).

Natural Gas Conversion Installation

This is more complex because it involves running gas line infrastructure.

Step 1: Plan the gas line route. Determine where your nearest gas source is (meter, exterior connection, existing line) and the path to the pit. The line typically needs to be buried or protected in conduit.

Step 2: Obtain permits. Most municipalities require permits for new gas line installation. Contact your local building department. Plan for inspection before and after the work.

Step 3: Run the gas line. This should be done by a licensed gas fitter or plumber certified for gas work. They'll run the line, bury or protect it properly, connect it to your gas source or meter, and pressure-test the entire system.

Step 4-6: Same as propane (install burner, test, add media).

Total time: 1-3 days depending on line routing and inspection schedules. Cost: gas line installation ($500-2000+) plus kit ($200-800).

Key Installation Considerations

Gas line sizing: The line diameter must match the burner's gas demand. A 20,000 BTU burner and a 50,000 BTU burner need different line sizes. The installer or kit manufacturer will specify the required line diameter.

Pressure and regulation: Propane uses higher pressure than natural gas. Your regulator must be matched to your fuel type and burner specs. This isn't something to improvise—wrong regulation means poor performance or safety hazards.

Shutoff valve: Install a shutoff valve accessible near the pit so you can quickly shut off gas if needed. This is a safety essential, not optional.

Inspection: For natural gas, a professional inspector will check the installation. Even for propane, having a professional verify your connections is smart.

Conversion Media: Making It Look Right

The decorative media sitting on your burner makes the difference between "this looks like a burner" and "this looks intentional."

Lava rock: Classic choice. Retains heat beautifully, creating radiant warmth that extends long after the burner cools. More rustic aesthetic. Can harbor mineral buildup over time.

Glass beads: Modern, clean look. Glimmer and reflect light beautifully. Don't retain heat (the flame is the heat source). Less maintenance—they don't break down like lava rock eventually does.

Ceramic logs: Mimic traditional wood, which appeals to people still emotionally attached to the wood-burning experience. Moderate heat retention. Good middle ground between rustic and modern.

Stones: River rocks, decorative stones, or landscape rocks work. Function depends on the stone type, but mostly they're visual. Moderate heat retention.

Choose media based on the aesthetic you want and the heat experience you're targeting. If you want maximum radiant warmth, lava rock wins. If you want clean, contemporary aesthetics, glass wins. Either way, refresh the media annually to keep it looking intentional.

Safety Considerations for Conversion Pits

Clearance and sightlines: Your converted pit still needs 3+ feet of clearance around it from flammable materials. Keep it away from structures, dry vegetation, and lightweight items.

Ventilation: Gas burners consume oxygen and produce CO2. If your pit is in a completely enclosed space (which wouldn't be typical for an outdoor pit), ventilation matters. For outdoor patios, this is not a concern.

Gas leak detection: After installation, inspect connections regularly. If you ever smell gas near the pit, immediately turn off the valve and don't use the pit until a professional has inspected it. Trust your nose.

Burner maintenance: Periodically clean the burner ports with a fine brush to ensure even flame distribution. Mineral deposits can clog ports. A clean burner performs better and looks better.

Flame safety: The burner will be hot. The rim of the pit will be hot. Keep children and pets supervised and aware of the hazard, just as you would with any fire feature.

Quality Conversion Kit Brands

Fire Magic makes conversion kits that feel integrated into high-end outdoor design. Excellent burner quality and aesthetics.

Summerset offers accessible conversion kits that work well in existing pit structures. Good value without sacrificing quality.

Blaze provides solid conversion options with reliable ignition and good flame distribution.

TrueFlame specializes in conversion systems designed for various pit sizes and configurations.

Avoid ultra-cheap kits from big-box retailers. They typically have unreliable ignition, uneven flame, and burners that feel obviously retrofitted. Spend the extra $200-300 on a quality kit—you'll use it dozens of times a year, and reliability matters.

FAQ

Can I convert any wood-burning pit to gas?

Most, yes. The pit needs to be structurally sound and sized to accommodate a conversion kit. Very small pits or pits with unusual geometry might not work. Measure your pit and check with the kit manufacturer before assuming compatibility.

Will my converted pit still look natural, or will it look obviously retrofitted?

With quality media and a good kit, it looks completely intentional. Poor kit selection and cheap media make the retrofit obvious. Invest in aesthetics, and it will look like you designed it that way from the start.

How much does a complete conversion cost?

Propane: $250-1000 total (kit + initial fuel). Natural gas: $700-2500+ (line installation + kit). Varies significantly based on pit size, fuel choice, and installation complexity.

Can I convert back to wood-burning if I change my mind?

Technically yes, but practically no. Once you've adapted the pit for gas, using wood becomes awkward and potentially unsafe. Think of gas conversion as permanent. Make sure you want it before you commit.

What maintenance does a converted pit require?

Minimal. Clean the burner ports seasonally. Check connections annually. Refresh media if it looks dingy. That's it. Gas is low-maintenance compared to wood.

Is natural gas or propane better for a conversion?

Propane if you want simplicity and portability. Natural gas if you want unlimited fuel and lowest long-term operating cost. Both work great; the choice is about your situation and priorities.

Final Thoughts

Converting a wood-burning fire pit to gas is one of the best quality-of-life upgrades you can make for your outdoor space. You get all the ambiance and presence of fire with none of the hassle—no wood gathering, no smoke, no endless cleanup.

Choose your fuel type based on your situation. Choose your kit based on quality and aesthetics. Get professional help if you're running natural gas. And enjoy the simplicity of push-button fire whenever you want it.
