Fire Pit Burner Kits

A fire pit burner kit converts any non-combustible enclosure into a gas fire feature. The kit supplies a matched set of components: a burner in your chosen shape, a pressure regulator, flex gas line, a key valve, and ignition. The result is controlled flame you can start in seconds and shut off completely, with no ash, no embers, and no firewood to manage.

Before selecting a kit, confirm your fuel source. Propane and natural gas fire pit burner kits use different orifice sizes and regulators. A propane burner on a natural gas line produces a weak, undersized flame. A natural gas burner on propane runs at dangerous pressure. Fuel type is not adjustable after purchase, so it is the first decision you make.

Burner shape determines the flame pattern. H-burners produce a wide, multi-point flame suited to square and rectangular enclosures. Ring burners drop into round fire pit burner kit. Linear burners create a single ribbon of flame for trough-style designs. Fire Pit Surplus carries fire pit burner kits as an authorized dealer for the brands we stock, with options across all three burner shapes.

Why Choose a Gas Fire Pit Burner Kit

  • Complete system in one order: Every kit includes a matched burner, regulator, flex line, and ignition, eliminating the guesswork of sourcing compatible components separately.
  • Works with any non-combustible enclosure: Concrete, corten steel, natural stone, or pavers, positioned at least 10 feet from any structure or combustible material per U.S. Fire Administration guidelines. As long as the enclosure meets that clearance and the required depth and wall dimensions, a gas burner for fire pits drops in without structural modification.
  • Upgrade without replacing: A burner kit lets you add gas to an existing wood burning fire pit, keeping the enclosure you already have while eliminating ash cleanup and wood handling.
  • Instant on, instant off: Gas burner kits light in seconds and extinguish completely, with no cool-down period and no cleanup between uses.

What to Look for in a Fire Pit Burner Kit

Fuel Type: Propane vs. Natural Gas

  • Propane (LP): Propane burner kits connect to a portable tank and are the right choice for patios without a dedicated gas line. Propane burns hotter per cubic foot, so the orifice is sized smaller than a natural gas equivalent.
  • Natural gas: Natural gas kits connect permanently to a home gas supply and never require tank refills. The orifice is larger than propane to compensate for lower delivery pressure, and most local codes require a licensed contractor to run the supply line.
  • Not interchangeable: A propane kit on a natural gas line produces a weak, undersized flame. A natural gas kit on propane runs dangerously over-pressured. Order the version that matches your fuel source and confirm with your installer before purchasing; the EPA's BurnWise program identifies fuel-type mismatch as among the most common errors in residential gas fire feature installation.

Burner Shape: H-Burner, Ring, and Linear

  • H-burner fire pit: The H-shaped frame produces flame from multiple points across its width, creating a full, layered look across square and rectangular enclosures. It is the most versatile shape for DIY fire pit projects and covers the widest range of enclosure dimensions.
  • Round ring burner: Ring burners fit circular fire pits and fire bowls. The ring diameter should sit at least six inches from the interior wall on all sides to allow adequate airflow and prevent enclosure damage from concentrated heat.
  • Linear burner: Also called a trough burner, the linear design runs across a single axis and creates a ribbon-style flame ideal for long, narrow channel enclosures. It is the right choice when the enclosure depth is limited and the length is the primary dimension.

BTU Output and Burner Size

  • Match BTU to enclosure volume: A 50,000 BTU burner suits enclosures up to about 24 inches. Larger enclosures or commercial applications typically need 75,000 to 100,000 BTU to produce a visible, satisfying flame across the full enclosure area.
  • Size in inches is the burner, not the enclosure: Burner kits are listed by the width or diameter of the burner itself. Measure your interior enclosure dimension, subtract 12 inches for wall clearance on both sides, and that is your target burner size.
  • Fire media affects perceived output: Lava rock and fire glass spread flame across the enclosure surface and change the visual character of the flame. Use fire pit media rated for high-temperature gas use to prevent cracking from thermal shock.

Construction and Ignition Options

  • Stainless steel burners: Stainless steel fire pit burners are the standard material for outdoor fire pit burner kits. They resist rust, handle repeated heat cycling, and hold up in humidity and coastal conditions without surface degradation.
  • Brass fire pit burners: Brass is a premium alternative with excellent corrosion resistance and a warmer appearance. It performs well in humid and coastal climates and is a common choice in high-end custom fire pit builds.
  • Ignition options: Electronic ignition lights the burner at the turn of a valve with no open flame required. A manual spark ignitor is a simpler, lower-maintenance alternative suited to straightforward outdoor installations.

Frequently Asked Questions

What size fire pit burner do I need?

Measure your enclosure interior and subtract 12 inches for required clearance on each side. An 18-inch burner suits compact builds. Enclosures over 30 inches typically need a 24- to 30-inch burner with a higher BTU output to produce a visible flame across the full space.

What is the difference between a propane and a natural gas fire pit burner kit?

Propane and natural gas use different orifice sizes and operate at different pressures. A propane burner on a natural gas line produces a weak flame. A natural gas burner on propane runs over-pressured. The versions are not interchangeable; confirm fuel type before purchasing.

What is the difference between an H-burner, linear burner, and ring burner for a fire pit?

An H-burner produces a multi-point flame across square and rectangular enclosures. A ring burner fits circular fire pits and fire bowls. A linear burner creates a ribbon flame across trough and channel designs. Burner shape should always follow enclosure shape.

How do I choose a fire pit burner for a DIY fire pit?

Confirm your fuel source first, then choose burner shape based on enclosure design. Verify the BTU output suits your enclosure size and that the burner fits with at least six inches of clearance on all sides. Order the correct fuel-type version before your gas rough-in begins.

Do gas fire pit burners work with existing wood fire pits?

A gas burner kit installs in most non-combustible enclosures, converting a wood fire pit to gas. The enclosure must meet minimum depth and clearance requirements. Open grate-style fire pits will not work; the enclosure must have solid, non-combustible walls and a flat base.
