How to Build a Gas Fire Pit (The Smart Way to Do It Right)

Build it yourself—with professional-grade components designed to last

Whether you’re planning a DIY backyard build or designing an outdoor living space for a client, building your own gas fire pit can be simple, safe, and stunning—if you start with the right components.

In this guide, we’ll walk you through how to build a gas fire pit using professional-grade kits and accessories trusted by contractors, designers, and homeowners across the country.

Why Build Your Own Gas Fire Pit?

There’s pride in creating something yourself. But more than that, a custom fire pit lets you design the exact look and experience you want—without being limited by cookie-cutter kits.

Whether you’re a homeowner creating your dream patio or a contractor building for a client, your goal is the same:

A reliable fire feature that looks great, performs flawlessly, and lasts for years.

That’s where professional-grade components make all the difference.

Step 1: Choose Your All‑in‑One DIY Fire Pit Kit

Why pick separate parts and guess what fits?

With American Fire Products DIY Fire Pit Kits, you get:

• A pre-matched burner + pan + ignition system

• No mismatched components

• Premium 304 stainless steel

• Options for every design, fuel type, and budget

This is the heart of your fire pit. Most bad DIY builds start with incorrect burners, wrong orifice sizing, or ignition systems that aren’t rated for outdoor conditions.

What to Consider When Choosing Your Kit Components:

• Shape & Size – Round, square, rectangular, or linear

• Fuel Type – Propane or natural gas

• Ignition Style – Match-lit (budget), Spark (push-button convenience), or All-Weather Electronic (premium remote-ready)

Pro Tip: Even though the enclosure is technically built in Step 2, selecting your kit first ensures you build the enclosure to the correct cut-out dimensions.

Step 2: Build the Enclosure

Now that you’ve selected your kit, you can build your structure to the exact dimensions required.

Your enclosure defines your fire pit’s shape, height, and style — and determines how well the components fit.

The easiest DIY approach:

Use pavers, retaining wall blocks, or stone veneer available at any major retailer.
Then pair them with an American Fire Products kit for a professional-grade finish.

Design Tips:

• Keep your enclosure at least 18" tall for comfortable viewing and safety.

• Leave access points for gas shutoff valves and vents.

• Choose materials rated for high temperatures

• If using propane, ensure space for tank placement and ventilation.

Once your enclosure is built and measured, you can drop in your fire pit kit.

Step 3: Add Proper Ventilation

Safety first. Ventilation is what separates a fire pit that performs from one that puts your home at risk.

Without proper airflow, gas can build up inside the enclosure and create potential issues—leading to delayed ignition or worse.

What you need:

• At least 36 square inches of airflow on opposite sides of your enclosure

• Durable, aesthetic vent covers like our 12" x 6" Slotted Steel Fire Pit Vent (2-pack)

Ventilation isn’t optional. It’s protection for your project, your property, and your peace of mind.

Step 4: Add Fire Media That Fits Your Style

Once your burner is installed, it’s time for the finishing touch: fire media.

This is where design meets performance. The fire media you choose affects flame visibility, heat efficiency, and overall aesthetic.

Step 6: Connect, Test, and Enjoy

Now for the final step—bringing the heat.

But first, test everything properly. If you’re not comfortable or unfamiliar with gas components, hire a professional. It’s not worth the risk.

• Connect your gas line

• Check all fittings for leaks

• Verify the ignition system

• Add your media and light it up

Your fire pit should be safe, clean-burning, and beautiful. When done right, it feels like a professional installation—because it is.
