Gas fire pits are a great way to add warmth and ambiance to your outdoor living space. In this blog post, we'll break down the anatomy of a gas fire pit. We'll cover what you need to know before purchasing one for your backyard - how they work, different types, and various options. So if you're considering sprucing up your outdoor living space with the addition of a gas fire pit, read on!

A gas fire pit has the following components, each with its own function:
  • The enclosure provides safety from sparks and embers by containing them within the unit
  • Fire media helps distribute the heat and flame while providing a beautiful accent and character to the fire feature
  • The burner is the heating element that produces the flame
  • The pan sits below the burner and keeps the fire media from falling into the enclosure cavity
  • An ignition system to start the burner
  • A control knob to adjust the flow of gas and intensity of the flame
Gas fire pits are a great way to enjoy the warmth of an outdoor fire without the mess because they require less maintenance than wood-burning fire pits. To help you make the most informed decision for your backyard, here is a breakdown of the individual components, how they work together, and the various options available.

The Anatomy of a Gas Fire Pit - Components

We'll start by going over what kind of materials are typically used in construction and the main components of a fire feature so that you can decide which is right for you.  


There are many different types and shapes of enclosures available for purchase. From stone, brick, and concrete blocks to custom framing and surfacing, fire features can be configured in various shapes and heights. Firegear offers our Sanctuary Series of prefabricated fire features, Kalea Bay Outdoor Linear Gas Fireplace, and complete packages to turn any fire pit enclosure into a custom gas fire pit.

Burner & Pan

The burner converts gas to flame to provide heat and an array of flame presentations depending on the configuration of the burner. The pan sits directly under the burner to isolate it from the open cavity below and hold the fire media in place. Pans are usually recessed into the enclosure and come in various shapes and sizes to match the design of the fire feature and the burner.

Fire Media

Fire media provides invaluable function and beautiful decoration to match the aesthetic of the space. The media is placed on top of the burner in the pan, creating a natural flame pattern and distributing heat evenly around the fire feature as the burner warms it. Fire media comes in lava rock and stone, fire glass of various colors, and log sets made of concrete or steel to fit your preferred ambiance.

Connectors, Fittings, and Vents

To provide a safe and efficient flame, the gas line or propane tank must be properly connected to the burner and control valve. Every gas fire pit will use a combination of connectors, fittings, and hoses to connect the ignition system, control valve, and burner to the fuel source. Built-in vents ensure that the enclosure gets plenty of airflow and water drainage. Adequate airflow prevents excess gas from building up in your fire feature, leading to ignition problems or unsafe conditions.

The Anatomy of a Gas Fire Pit - Control Options

  • Control Knob - The control knob operates the gas valve to open or close the flow of gas to the burner. Also called a regulator, this can vary the size of the flame and the amount of heat emitted.
  • Push-Button Igniter - The push-button igniter is a simple ignition system that creates a spark to ignite the burner and start your fire feature.
  • Automatic Ignition - You will never need to worry about forgetting to turn off your fire pit again when you have an automatic ignition system. An automated system can be controlled with a remote or wall switch, configured to operate multiple fire features simultaneously, and uses an electrical connection that is safe, easy to use, and reliable.
  • Switches & Timers - For a more convenient operation of your fire feature, automatic ignition systems can be controlled from a simple wall switch or timers.
  • Remotes - Some automatic ignition systems provide wireless support with a fire pit remote, a great way to get the perfect ambiance without leaving your seat. If you're feeling chilly, just turn on the fireplace wirelessly, or turn it off when it gives more heat than needed. 

The Anatomy of a Gas Fire Pit - Accessories

  • Windshields - A windshield sits around the media and burner, protecting the flame from a chilly breeze. Wind guards are not required but can be very practical if you live in an area with high winds or unpredictable weather patterns.
  • Covers & Lids - The best way to keep your fire pit in pristine condition is by investing in protective covers. Custom-fitted weather-proof vinyl covers are designed to cover the entire fire feature, protecting from debris, harsh weather, dust build-up, and tampering from little ones. Steel lids are another option that only covers the top of the feature, keeping the burner, fire media, and pan area clean and protected.
