Round Gas Fire Pit Kits

Simplify your custom project with a round gas fire pit kit from Firepits Direct, which bundles high-performance burners and precision-engineered pans into one pre-calibrated assembly. These all-in-one kits ensure 360 degrees of reliable warmth and optimal airflow, making them the perfect functional core for any circular outdoor feature.

How To Optimize Your Circular Fire Feature

Why Choose A Circular Burner Kit?

Round fire pits remain the most popular choice for social outdoor spaces because they facilitate a communal, "campfire" seating arrangement. A dedicated round kit ensures that the flame remains centered and balanced, preventing the heat from drifting toward one side of the enclosure. For the professional contractor, these kits provide:

  • Even Flame Distribution: Our round burners use concentric rings or "spoke" patterns. This fills the center of the pit and eliminates "dark spots."
  • Strong Pan Support: Circular pans (flat or drop-in) provide a stable base for heavy fire media. They also protect gas lines and valves from the weight of stone or glass.
  • Simple Gas Plumbing: Every kit includes a pre-assembled manifold. These are leak-tested and matched to the correct BTU output for the burner size.

How To Select The Optimal Round Kit

Burner Style: Choose Your Flame Impact

Standard stainless steel rings are reliable, but premium projects often need a bigger "wow" factor.

  • HPC Penta Burner: A popular upgrade. Its five-lobed design creates a full, natural flame that looks much thicker than a standard ring.
  • High-Output Brass: The "commercial-grade" choice. These use venturi-jet technology to create a large, roaring fire that mimics a real wood-burning pit.
  • The Bottom Line: Both penta and brass options offer better performance and a cleaner look for high-end custom builds.

Pan Design: Drop-In Vs. Flat Plate

The pan choice usually depends on how much time you have for the install.

  • Drop-In Pans: These have a lip that hangs from a ledge inside the pit. They are the easiest to install and the simplest to pull out for future maintenance.
  • Flat Plates: These sit on a hidden ledge. Choose these for a flush-mount appearance where the pan is completely hidden by the coping.

Ignition Options: Safety And Ease Of Use

Match your ignition system to the job site and local laws.

  • Match-Lit: Simple and virtually maintenance-free. These are great for standard residential homes.
  • Electronic (110V or Battery): These include auto-relight features. Use these for windy coastal areas or commercial jobs where safety codes require automatic shut-offs.

Proper Sizing For Custom Enclosures

Precision sizing prevents the masonry from cracking or the metal from warping.

  • Flat Pans: Size these 1/2 inch to 1 inch smaller than the pit opening. This allows the metal to expand when it gets hot without damaging the stone.
  • Drop-In Pans: These need a nearly exact fit so the lip sits securely on the interior ledge.
  • The 3-Inch Rule: The burner itself should be at least 6 inches smaller than the pan. This leaves a 3-inch buffer of fire media (lava rock or glass) between the flame and the enclosure wall.
    Note: Always consult with a product specialist before ordering custom enclosures.

Round Fire Pit Kit FAQs

  • What is the best size burner for a 36-inch round fire pit?

    To determine the best burner, you must account for wall thickness (typically 4" to 8"); for example, a 48" overall enclosure with 6" walls results in a 36" interior opening. For a 36" opening, we recommend a 35" to 36" pan paired with a 24" to 30" burner, depending on the manufacturer’s specific clearance requirements. This configuration maintains a 3" to 4" "buffer zone" of fire media to protect the masonry from heat while ensuring a centered, realistic flame. This sizing strategy accounts for thermal expansion and ensures a safe, professional-grade installation.

  • Can I use a round kit for a propane fire pit?

    Yes, but it is critical to select a propane-specific kit. Propane kits include a specialized air mixer and are designed to prevent gas from "pooling" at the bottom of the pan. Because propane is heavier than air, using a natural gas kit with propane fuel can lead to dangerous soot buildup and potential combustion issues.

  • How much fire glass do I need for a round kit?

    Media volume depends on the diameter and depth of your pan. For a 24-inch round pan with a standard 2-inch depth, you will generally need 50 to 60 pounds of fire glass. If you are using lava rock as a base to save on costs, you can reduce the glass requirement to roughly 20 to 30 pounds for the top layer.
