Types of Fire Pit Burner Kits

Beyond the fuel source, fire pit burners come in various forms, often as kits that simplify the installation process. These kits provide most of the essential components needed to create a functional and attractive fire pit.

Pre-Made Fire Pit Burner Kits

These are ready-to-install units that often include a burner, pan, and sometimes a frame or grate. They are designed for ease of use and can significantly speed up the installation process.

What to expect:

  • Burner with Pan: The burner ring is typically mounted within a metal pan that holds the media (like lava rock or fire glass) and collects any excess gas or debris.
  • Ignition System: Options range from manual ignition (lighting with a match or lighter) to electronic ignition systems for greater convenience and safety.
  • Valve and Control: This allows you to adjust the flame height and turn the burner on/off.
  • Fuel Connection: Comes with fittings for either propane tanks or natural gas lines.

DIY Burner Components

For those who enjoy a more hands-on approach or have a specific design in mind, you can purchase individual burner components to build your own custom fire pit.

Key DIY Components:

  • Burner Ring/Wok: This is the part that distributes the gas, creating the flame. They come in various shapes (round, linear) and sizes.
  • Fire Pit Pan: A shallow metal pan that sits beneath the burner ring, providing a surface to hold the media and direct heat.
  • Gas Hose and Regulator (for propane): Essential for connecting the burner to a propane tank.
  • Gas Valve and Manifold: For controlling gas flow. Stainless steel or brass are good choices for durability.
  • Ignition Kit: Purchase a separate ignition system or manual striker.

Building your own can be rewarding, allowing you to integrate the burner into existing structures like custom-built fire pit enclosures made from brick, stone, or concrete. Remember to always follow manufacturer guidelines and local building codes when undertaking a DIY project.

Choosing the Right Size and Shape Burner

The size and shape of your fire pit burner depend on several factors, including the dimensions of your fire pit structure, the desired flame effect, and the type of fire pit media you plan to use.

Burner Size Guidelines

A good rule of thumb is to have the burner ring be roughly half to two-thirds the diameter of your fire pit bowl. For example, in a 30-inch diameter composite bowl, a 18-24 inch burner ring would be appropriate. This leaves enough space around the burner for safety and for the media to surround the flame.

Burner Shape Considerations

Round Burners: These are the most common and are best suited for traditional circular fire pits. They provide a uniform flame that radiates outwards in all directions.

Linear Burners: These long, narrow burners are excellent for modern, rectangular, or linear fire pits. They create a sleek, dramatic flame effect that is perfect for contemporary outdoor designs.

H-Burners: Shaped like the letter ‘H’, these provide a robust and often larger flame, ideal for bigger fire pits where a more intense fire is desired.

Spider Burners: These have multiple arms extending from a central hub, designed to distribute flames evenly in larger, irregular shaped fire pits.

The shape of your container (bowl, linear trough, square) will heavily influence the shape of the burner you choose. For instance, a linear fire pit demands a linear burner to achieve the intended aesthetic and flame pattern.

Materials and Durability

When selecting a fire pit burner, the materials used are crucial for longevity and safety, especially since it will be exposed to high heat and outdoor elements.

Stainless Steel Qualities

High-quality stainless steel is the gold standard for fire pit burners. Look for burners made from 304-grade stainless steel. This grade offers excellent resistance to rust, corrosion, and warping, even under extreme heat and repeated use.

  • Durability: Can withstand harsh weather conditions.
  • Heat Resistance: Holds up well to the intensity of flames.
  • Corrosion Resistance: Prevents rust, which is vital for outdoor equipment.

Other Materials to Consider

While stainless steel is preferred, you might encounter burners made from other materials. Cast iron can be used, but it’s more prone to rust if not properly cared for and coated. Aluminum is lighter but may not withstand extreme heat as well as stainless steel over the long term. Always check manufacturer specifications to ensure the burner is designed for outdoor fire pit use.

Installation: Safety First!

Installing a fire pit burner correctly is paramount for safety and the proper functioning of your unit. Whether you’re using a pre-made kit or building from scratch, always prioritize safety.

Propane Fire Pit Burner Installation Steps

Here’s a general overview of the steps involved. Always refer to your specific burner’s manual for detailed instructions.

  1. Choose a Safe Location: Select a level, stable surface away from any flammable
    materials (trees, fences, structures). Check local fire codes for required clearances. The National Fire Protection Association (NFPA) offers valuable safety guidelines for heating equipment.
  2. Assemble the Fire Pit Structure: If building your own, ensure it’s sturdy and fire-resistant (e.g., concrete, bricks, stone).

Installing a natural gas burner typically involves hiring a professional, but understanding the process is helpful.

  1. Professional Gas Line Installation: A certified gas fitter will run a gas line from your home’s main supply to the desired fire pit location. This involves trenching and connecting pipes according to local codes and safety standards. The International Code Council (ICC) publishes codes that govern safe gas installations.
  2. Burner and Pan Placement: Once the gas line is in place, the burner pan is installed, and the gas line is connected to the burner’s valve system.
  3. Leak Testing: The entire gas line and connection are rigorously tested for leaks.
  4. Media Installation: Lava rocks or fire glass are added around the burner.
  5. Ignition and Testing: The unit is then tested for proper ignition and flame control.

Fire Pit Burner Media: What to Fill It With

The media you choose not only affects the look of your fire pit but also how efficiently it burns and how much heat it radiates.

Lava Rocks

Lava rocks are a natural byproduct of volcanic activity and are a very popular choice. They are porous, lightweight, and can withstand high temperatures.

  • Pros: Natural look, good heat retention, affordable, porous nature allows for good gas distribution.
  • Cons: Can be dusty, may break down over time, less variety in color and appearance compared to glass.

Fire Glass

Fire glass is tempered glass that has been tumbled and polished to remove sharp edges. It’s heated and cooled in a controlled process so it can withstand the heat from fire pit burners without shattering.

  • Pros: Modern and sleek look, wide range of colors and finishes (reflective, color-infused), easy to clean, doesn’t produce soot or ash.
  • Cons: Can be more expensive than lava rocks, some types can get very hot to the touch, can lose some of its reflectivity over time.

Ceramic Fire Logs/Beads

These are designed to mimic the look of real wood and provide a more traditional fire appearance. Ceramic can retain and radiate heat effectively.

  • Pros: Realistic appearance, good heat radiation, durable.
  • Cons: Can be heavy, specific styles might be more expensive.

Important Note: Never use regular river rocks or stones in your fire pit. These can absorb moisture and explode when heated. Always use media specifically designed for fire pits.
