Before you start going through the process on how to build a gas fire pit, here are some things that you should add to your checklist.


Identify which type of fuel you want your gas fire pit to run on.

Liquid Propane Gas

Propane fuel type is usually chosen for portable fire pits that also require minimal or no installation. You can simply hook up the propane tank to your fire pit and turn it on to start your fire.

Natural Gas

Using this type of fuel means that you are actually attaching your fire pit to the natural gas line of your home. This usually works for the permanent type of fire pit structure since you don’t have multiple gas lines running underneath your property that you can access at any given spot.

You will need to hire a professional or licensed gas plumber to install a gas line and hook it up to your fire pit in case there is no gas line available in your area or in the part of your property which you want to build your fire pit in.


You have to consider what type of enclosure or body your fire pit will have. This enclosure is where you will house the burner, gas and all components you need for ignition or lighting the fire. You have the option to build your enclosure out of masonry bricks or purchase a fire pit kit.

DIY fire pit kits is usually the go-to option when building a gas-powered fire pit from scratch. It comes with all the components you will need as well as an unfinished enclosure or masonry bricks that you can put on top of the other by yourself.

The gas fire pit kit will usually feature an enclosure with a welded steel frame, Hardie Board shell which you can finish with concrete pavers, stone, tiles, brick or metal. You can choose its color or texture to match your existing outdoor furniture or backyard décor as well.



A burner is definitely the integral part of your DIY gas fire pit. This is used to burn the gas as well as being responsible for the size and height of the fire you want to produce. Burners are available with a wide array of shape, size and materials. You can purchase it individually or get a fire pit burner kit which already contains the necessary parts to assemble your gas fire pit burner system.

Different burners also feature different BTU capacities. A regular gas fueled fire pit requires about 40,000BTU or heat output to warm you and your guests comfortably as you sit around your fire pit. If you want it to be hotter, opt for the 50,000 to 60,000 BTU burner.


Most gas fire pits use a burner pan only as an option but, it is highly recommended since it will help support the burner. Burner pans also come in different shapes and sizes. It is a base plate placed beneath your fire pit burner in order to prevent the gas from sinking into your fire pit. It can be attached or unattached to the burner and it also holds the medium to cover or provide the backdrop to your flames.

Burner Cover or Flame Backdrop

You need something to hide or cover your burner so the flames appear to be floating or naturally burning as if you are burning wood. Gas fueled fire pits usually require lava rocks or fire glass which can also act as decoration or design to your fire pit.

Heat-tolerant materials such as lava rocks or fire glass come in various colors and sizes so you can customize it to match your aesthetics. Most consumers choose fire glass compared to lava rocks since they absorb and release heat more effectively, producing more heat.

Connectors and Fittings

Your gas fire pit will also enclose or house connector and fitting components so you will be able to route the gas to your burner. It requires gas regulator, valve, orifice and of course, the connector hose with fittings which is a small, flexible pie that attaches the gas valve to the burner.

Flame Ignition Type

The beauty of a gas-powered fire pit is how easy you can create or start a fire so do not forget to consider the ignition system you want to use to start as well as control the fire. You can light your fire pit manually or use a remote-operated or automatic system.

  • Match lit ignition – start a fire by simply turning on the valve of your gas supply and hold a lighter or a matchstick over the burner as you slowly turn on the gas. Adjust flame height by turning the valve.
  • Push-Button ignition – when you push the button, a spark is sent to your burner via a probe to light your fire pit. It does not require electricity to use.
  • Automatic ignition – requires an electrical connection so you will need a professional electrician to install a power line to route it in your fire pit or buy a battery powered system. You can start, control your fire pit via wall switch, remote control, Bluetooth app or a smart home system.

Automatic ignition is quite expensive but is considered the safest and fastest way to light a gas-powered fire pit. It also has a flame-sensing pilot feature that monitors the fire of your fire pit and shuts off the fuel supply in case your fire ever goes out.
