How to Choose the Right Gas Fire Pit Insert for Your Backyard Setup


Transforming your backyard into a cozy, inviting space starts with one key feature: the fire pit. If you're going the gas route, choosing the right fire pit insert can make all the difference in performance, safety, and style. In this guide, we’ll walk you through everything you need to know to choose the perfect gas fire pit insert for your outdoor living area.

What is a Gas Fire Pit Insert?

A gas fire pit insert is the functional component of a fire pit that houses the burner, connects to the gas source, and distributes flames evenly. These inserts come in various shapes, sizes, and ignition types, allowing you to build a custom fire pit or upgrade an existing one.

Key Factors to Consider

1. Fuel Type: Natural Gas vs. Propane

  • Natural Gas is best for permanent installations with an existing gas line.

  • Propane (LP) is ideal for portable or remote setups where gas lines aren't accessible.

Tip: Always choose an insert that matches your fuel source to avoid compatibility issues.

2. Shape & Size of the Insert

  • Round Inserts – Best for circular or bowl-style fire pits.

  • Square or Rectangular Inserts – Ideal for modern or linear fire pit designs.

  • Custom Sizes – Great for unique installations.

Measure your fire pit enclosure to choose the right insert size. Allow at least 3–6 inches of clearance on each side.

3. Ignition Options

  • Match Lit – Simple, budget-friendly, manual ignition.

  • Spark Ignition – Adds a push-button start for convenience.

  • Electronic Ignition (AWEIS) – Premium, remote or app-controlled options with auto safety shutoff.

For homes with children or high wind areas, consider the electronic ignition with built-in safety features.

4. Burner Material

  • Stainless Steel Burners – Rust-resistant and durable, perfect for outdoor use.

  • Brass Burners – Higher-end, corrosion-resistant, and offer even flame distribution.

 Avoid lower-grade metals that may corrode quickly when exposed to outdoor elements.

5. Fire Media Compatibility

  • Choose inserts compatible with your desired fire media: lava rock, fire glass, or ceramic logs.

  • Ensure the pan depth supports your media to cover the burner evenly without choking the flame.

Pro Tip: Fire glass offers a vibrant, modern aesthetic and reflects heat beautifully.

6. Ventilation & Safety Requirements

  • Proper ventilation is critical to prevent gas buildup.

  • Inserts should be installed with vent blocks or vents in the fire pit enclosure.

  • Always follow local building codes and use a certified installer if unsure.

Additional Features to Look For

  • CSA Certified Inserts for added safety and code compliance.

  • Drop-in pans with weep holes for water drainage.

  • Adjustable flame controls.
