6 Steps Guide on How to Convert Propane Fire Pit to Natural Gas

1. Turn Off the Gas Supply 

The process of converting a propane fire pit to a natural gas fire pit is relatively simple and provides an ideal solution if you’re looking for a more convenient or cost-effective option. Before you commence any conversion, however, it’s essential that you first turn off the gas supply and make sure that the connection between the propane tank and fire pit is securely disconnected. 

First Turn Off the Gas Supply

This minor but important preparatory detail will help ensure safety during the conversion process and save you time in having to restart it, should anything come loose while converting.

2. Attach the Natural Gas Connection Kit’s Regulator Hose

Installing a natural gas line is quite a straightforward process, provided specific steps are followed. Once you have disconnected the propane tank and removed it from the area, attach the regulator hose that comes with your natural gas connection kit to the shut-off valve of your natural gas line. 

It is essential to use pipe thread sealant or joint compound on all fittings, as this creates an airtight seal for safe operation. After these specifications have been met, you will be well on the way to installing your new natural gas line.

3. Wrap the Threads of Your Fire Pit’s Gas Control Valve

Ensure your gas control valve is completely sealed and protected from any potential leaking. It’s important to wrap the threads of your fire pit’s 1/2-inch NPT female threaded coupling, as well as any other exposed pipe threads. 

With Teflon tape.

This will assist in creating a seal that will help prevent moisture or other contaminants from entering the gas lines and thus leading to a potentially hazardous situation.

 Moreover, Teflon tape can also offer additional protection against rusting by preserving the metal joints and helping minimize wear and tear due to its thermal properties. Make sure to properly install the Teflon tape for added protection against leakage when connecting it with Natural Gas.

4. Attach the Regulator Hose 

To connect the regulator hose to the gas control valve securely and efficiently, you should select a 1/2-inch NPT female threaded coupling. 

When assembling your equipment, use a pipe wrench or an adjustable wrench to ensure the seal is tight when attaching the coupling to the control valve – this step is particularly important when dealing with natural gas. 

Connect the Regulator Hose

Some extra caution should always be taken when doing gas connections, as failure to attach them properly can result in hazardous conditions. With attention to detail and proper tool selection, you can create a safe environment for your home or workplace.

5. Turn on the Natural Gas Supply 

Turning on the natural gas supply and testing for leaks using soapy water is an important step in ensuring a good seal. When done properly, this process uses a combination of thorough visual inspection and a soap & water solution to detect even the smallest bubbles that may indicate a leak. 

After turning on the gas supply and testing with soapy water, it is critical to make sure that all connections were inspected and no bubbles were present before giving the go-ahead to use the line. 

While getting professional help is encouraged to ensure safety, knowing proper procedures and protocols can be extremely helpful.

6. Adjust the Flame Height

When lighting your fire pit, the flame height should be adjusted to the ideal height for a good seal to Natural Gas. If it is too low, the fire won’t produce enough heat, and if it is too high the fuel will be wasted and could pose a safety risk. 

An expertly-lit fire pit has a pleasantly radiant warmth that extends beyond what’s necessary for cooking or heating a marshmallow. People often forget about this point when setting up their fire pits. Once adjusted correctly, you can look forward to many warm gatherings spent around your enjoyable companion – your gas-powered fire pit!

Pleasantly Radiant Warmth

By following these steps, you can easily convert your propane fire pit to one that runs on natural gas. Enjoy the warmth and beauty of a real wood-burning fire without having to worry about running out of propane or dealing with refills. With your new natural gas connection, all you’ll need to do is enjoy the fire!

Additional Tips to Convert Propane Fire Pit to Natural Gas

  1. Check your local codes and regulations. Before you begin any work on converting your propane fire pit to natural gas, it is important to check with your local codes and regulations to ensure that this is permitted in your area.
  2. Turn off the gas supply to the fire pit. Once you have confirmed that it is legal to convert your fire pit, the next step is to turn off the gas supply to the fire pit. This can usually be done by turning a knob or lever located near the gas line.
  3. Disconnect the propane tank from the fire pit. After the gas supply has been turned off, you will need to disconnect the propane tank from the fire pit. Again, there should be a knob or lever near the connection that will allow you to do this.
  4. Remove the burner assembly from the fire pit. The next step is to remove the burner assembly from the fire pit. This may require some disassembly, but it is generally not too difficult. Once the burner assembly is removed, you will be able to access the gas line.
  5. Cut off the end of the gas line that is connected to the propane tank. Using a cutting tool, such as a pipe cutter or a hacksaw, cut off the end of the gas line that is connected to the propane tank. This will allow you to install a new fitting that will connect to your natural gas line.
  6. Install a shut-off valve in the gas line. Before you connect your natural gas line to your fire pit, it is important to install a shut-off valve in the line. This will allow you to easily turn off the gas supply in case of an emergency.
  7. Connect your natural gas line to the shut-off valve using an approved fitting. Once you have installed a shut-off valve in your gas line, you can then connect your natural gas line to it using an approved fitting. Make sure that all connections are tight and secure before proceeding.
  8. Turn on the natural gas supply and test for leaks. Now that everything is connected, you can turn on your natural gas supply and test for leaks at all of the connections using soapy water or a leak detection solution.
