Step-by-Step Guide: Converting Your Natural Gas Grill to Propane


Step-by-Step Guide: Converting Your Natural Gas Grill to Propane

Converting your natural gas grill to propane is a practical decision for many outdoor cooking enthusiasts. Whether you’re moving to a location without a natural gas line or simply prefer the convenience of propane tanks, this guide will walk you through the conversion process step by step. Please note, it’s essential to follow all safety guidelines and consider consulting a professional if you’re unsure about any step.

Understanding the Basics

Before diving into the conversion process, it’s crucial to understand the differences between natural gas and propane. Natural gas is delivered through a pipeline, while propane comes in portable tanks. Propane offers a higher BTU (British Thermal Unit) rating than natural gas, meaning it burns hotter. This difference necessitates adjustments to your grill to ensure safety and optimal performance.

Tools and Materials Needed

  • Propane conversion kit (specific to your grill model)
  • Adjustable wrenches
  • Screwdrivers
  • Pipe wrench
  • Leak detection solution or soapy water
  • Protective gloves

Preparation Steps

  1. Consult your grill’s manual to ensure it’s convertible and to identify the correct conversion kit.
  2. Purchase the appropriate propane conversion kit for your grill model.
  3. Turn off and disconnect the natural gas supply to your grill.
  4. Remove the grill’s main gas line.
  5. Ensure the grill is cool and clean, removing any grease or debris.

Converting Your Grill

The conversion process involves several critical steps. Skipping any step or failing to follow instructions precisely can lead to safety hazards.

Step 1: Install the Propane Orifice

Replace the natural gas orifices with those provided in your conversion kit. The orifice controls the gas flow and must be specific to propane to ensure the correct air-to-gas ratio.

Step 2: Attach the Propane Regulator

Attach the propane regulator to your grill. The regulator controls the pressure of the propane gas, which is crucial for safe and efficient operation.

Step 3: Connect the Propane Tank

Securely connect the propane tank to the regulator using the hose provided in your conversion kit. Ensure all connections are tight to prevent gas leaks.

Step 4: Test for Leaks

Apply a leak detection solution or soapy water to all connections. Turn on the propane tank valve slightly. If you see bubbles forming, there’s a gas leak. Tighten the connections and retest until there are no leaks.

Step 5: Final Adjustments and Testing

Once you’ve ensured there are no leaks, turn on the grill to test the flame. Adjust the air shutter settings if necessary to achieve a blue flame with minimal yellow tips. This indicates complete combustion and proper adjustment.

Maintenance and Safety Tips

After converting your grill to propane, regular maintenance and safety checks are essential to ensure long-term performance and safety.

  • Regularly check for leaks using the soapy water method.
  • Clean your grill after each use to prevent grease buildup.
  • Always turn off the propane tank valve when the grill is not in use.
  • Store propane tanks outside, in an upright position, and away from direct sunlight.

Troubleshooting Common Issues

Even with careful installation, you may encounter some issues. Here are quick fixes for common problems:

Issue Solution
Low flame or uneven heating Check for clogged burners or incorrect orifice installation.
Yellow flame Adjust the air shutter to allow more air mix with the propane.
Gas smell when grill is off Check for leaks and ensure the propane tank valve is fully closed.


Converting your natural gas grill to propane can enhance your grilling experience by offering portability and higher heat output. By following this step-by-step guide, you can safely and efficiently make the conversion. Remember, safety is paramount, so don’t hesitate to consult a professional if you’re unsure about any part of the process. Happy grilling!
