Choosing the Right Replacement Burners for Nexgrill 720

Now that you’ve successfully removed the old burners, it’s time to consider which replacement burners will be the right fit for your Nexgrill 720. Choosing the right replacement burners is crucial for proper burner maintenance and ensuring proper burner installation.

When selecting replacement burners, there are a few things to keep in mind.

First, check the dimensions of your old burners to ensure the new ones will fit properly. Measure the length and width of the old burners to find the correct size. You can also refer to your Nexgrill 720’s user manual for the recommended burner size.

Next, consider the material of the replacement burners. Stainless steel burners are durable and resistant to rust, making them a popular choice. However, cast iron burners provide excellent heat distribution and retention. Consider your cooking needs and preferences when choosing the material.

Lastly, think about the number of burners you need. Nexgrill 720 models typically have multiple burners, allowing for different heat zones and more versatile cooking. If any of your old burners are still in good condition, you may only need to replace a few rather than all of them.

Installing the New Burners in Nexgrill 720

Once you’ve measured the dimensions and chosen the right replacement burners, it’s time to install them in your Nexgrill 720. Follow these steps for a smooth installation process:

  • Prepare the grill: Turn off the gas supply and disconnect the propane tank. Remove the grates and heat shields to access the burners.

  • Remove the old burners: Unscrew the mounting screws holding the old burners in place. Carefully detach the gas supply line from each burner.

  • Install the new burners: Align the new burners with the mounting holes and secure them using the provided screws. Reattach the gas supply line to each burner, ensuring a tight connection.

  • Reassemble the grill: Put the heat shields and grates back in place. Double-check that everything is securely fastened.

  • Test the burners: Reconnect the propane tank and turn on the gas supply. Light each burner and check for a steady, blue flame. Make sure all burners are functioning properly before proceeding.

If you encounter any issues during the installation or notice problems with the replaced burners, such as uneven flames or low heat output, troubleshoot by checking for any loose connections or blockages in the gas supply line. Adjust the burner valves and consult the manufacturer’s instructions for further troubleshooting steps.

Testing and Troubleshooting the Replaced Burners in Nexgrill 720

To ensure proper functionality, it’s important to test the replaced burners in your Nexgrill 720 by reconnecting the propane tank and turning on the gas supply. After installing the new burners, you’ll want to make sure they are working correctly before firing up a delicious barbecue.

There are a few testing methods you can use to ensure everything is in good working order.

First, check for any leaks by applying a solution of soapy water to the gas connections. If you see bubbles forming, there may be a leak that needs to be addressed before using the grill. Tighten the connections or replace any faulty parts as necessary.

Next, ignite each burner individually to verify that they are producing a steady flame. The flame should be blue and consistent, without any sputtering or flickering. If you notice any issues, such as uneven flame distribution or weak flames, there may be a problem with the burner alignment or gas flow. Ensure that the burners are properly aligned and that the gas supply is fully open.

Common burner issues may include blocked or clogged burner ports. To address this, turn off the gas supply and disconnect the burners. Clean them thoroughly with a wire brush or pipe cleaner to remove any debris or residue that may be obstructing the ports.


In conclusion, replacing the burners in your Nexgrill 720 is a straightforward process that can be easily accomplished with the right tools and instructions. By following the step-by-step guide provided, you can successfully remove the old burners and install the new ones.

Remember to choose the appropriate replacement burners for your Nexgrill 720 model. After installation, it’s crucial to test and troubleshoot the burners to ensure they are functioning correctly.
