Smoking meat is an art, a science, and a passion for many. Whether you’re a seasoned pitmaster or a weekend enthusiast, the fuel source you choose plays a crucial role in the flavor profile and overall smoking experience. Propane smokers are incredibly popular for their portability and ease of use, but natural gas offers advantages in terms of cost and consistent supply. This begs the question: Can you convert a propane smoker to natural gas? The answer is generally yes, but it’s a project that requires careful consideration, proper planning, and, in most cases, some modifications.
Understanding the Differences: Propane vs. Natural Gas
Before diving into the conversion process, it’s essential to grasp the fundamental differences between propane (LP gas) and natural gas (NG). This knowledge is crucial for understanding why modifications are necessary and how to perform them safely and effectively.
Propane is a liquefied petroleum gas, meaning it’s stored as a liquid under pressure. When released, it vaporizes into a gas. Natural gas, on the other hand, is primarily methane and is distributed through pipelines in a gaseous state.
The key difference affecting smoker conversions is the BTU (British Thermal Unit) content. BTU measures the amount of heat energy contained in a fuel. Propane has a significantly higher BTU content per cubic foot than natural gas. This means propane burners are designed to deliver more heat than natural gas burners of similar size.
Another important distinction is the operating pressure. Propane systems typically operate at a higher pressure (around 11 inches water column) than natural gas systems (around 4 inches water column). This difference in pressure dictates the size of the orifice, which controls the amount of gas flowing to the burner.
Why Convert to Natural Gas?
Several compelling reasons might lead you to consider converting your propane smoker to natural gas.
Cost Savings: Natural gas is often significantly cheaper than propane, especially if you have a natural gas line readily available. Over time, these savings can add up, making the conversion a worthwhile investment.
Convenience: No more trips to refill propane tanks! Connecting your smoker to a natural gas line provides a continuous and reliable fuel source, eliminating the risk of running out of propane mid-smoke.
Environmental Considerations: While both are fossil fuels, natural gas generally produces slightly less carbon dioxide per BTU than propane, making it a marginally more environmentally friendly option.
The Conversion Process: Step-by-Step
Converting a propane smoker to natural gas isn’t as simple as just hooking it up to a different gas line. It involves modifying the burner system to accommodate the lower BTU content and pressure of natural gas. Safety is paramount throughout this process, so if you are not comfortable working with gas appliances, it is strongly recommended that you hire a qualified professional.
Step 1: Assessment and Planning
The first step is to thoroughly assess your smoker and determine its suitability for conversion. Some smokers are specifically designed for propane only and may not be easily convertible. Look for models that have adjustable regulators or are known to be compatible with conversion kits.
You’ll also need to determine the BTU requirements of your smoker. This information is usually found in the owner’s manual or on a label attached to the smoker. This BTU information is crucial for selecting the correct conversion kit or components.
Finally, assess your natural gas line. Ensure it has sufficient capacity (BTUs per hour) to handle the smoker’s requirements in addition to your other natural gas appliances. An undersized gas line can lead to performance issues.
Step 2: Gather the Necessary Components
Most conversions require a conversion kit, which typically includes the following:
- Natural Gas Regulator: This reduces the natural gas pressure to the required level for your smoker (usually 4 inches water column).
- Orifices: These are small brass fittings that control the flow of gas to the burner. Natural gas orifices have larger openings than propane orifices to compensate for the lower BTU content of natural gas.
- Gas Hose and Fittings: Ensure the hose is compatible with natural gas and is the correct length to connect your smoker to the gas line.
- Instructions: Follow the instructions carefully, as they are specific to the conversion kit and your smoker model.
If a dedicated conversion kit isn’t available for your smoker, you might need to purchase these components individually. Make sure they are compatible with your smoker’s make and model.
Step 3: Shut Off the Gas Supply
Before beginning any work, completely shut off the gas supply to both the propane tank (if applicable) and the natural gas line. This is a crucial safety precaution. Disconnect the propane tank from the smoker.
Step 4: Replace the Regulator
Remove the existing propane regulator and replace it with the natural gas regulator. Ensure the connections are tight and properly sealed. Use pipe thread sealant (approved for gas applications) on all threaded connections to prevent leaks.
Step 5: Replace the Orifices
Locate the orifices on the burners. These are usually small brass fittings with a tiny hole in the center. Carefully remove the propane orifices and replace them with the natural gas orifices included in the kit. Be extremely careful not to damage the threads when removing and installing the orifices.
Step 6: Connect the Gas Hose
Connect the natural gas hose to the regulator and the natural gas supply line. Again, use pipe thread sealant on all threaded connections. Ensure the hose is properly secured and not kinked or damaged.
Step 7: Leak Test
After completing the modifications, perform a thorough leak test. Mix a solution of soapy water (dish soap and water) and apply it to all gas connections, including the regulator, orifices, and hose connections.
Turn on the natural gas supply slowly. If you see bubbles forming at any connection, there is a leak. Immediately shut off the gas supply and tighten the connection. Repeat the leak test until no leaks are detected. Never use an open flame to check for gas leaks.
Step 8: Initial Burn and Adjustment
After passing the leak test, turn on the smoker and observe the flame. The flame should be blue with a slight yellow tip. If the flame is mostly yellow, it indicates a lack of oxygen, and you may need to adjust the air shutter on the burner. Consult your smoker’s manual for instructions on adjusting the air shutter.
Allow the smoker to run for a while to ensure the burners are functioning properly and that the temperature is stable. You may need to make minor adjustments to the regulator or air shutter to optimize performance.
Step 9: Professional Inspection (Recommended)
Even if you are confident in your work, it is highly recommended to have a qualified gas technician inspect the conversion to ensure it was done correctly and safely. They can verify that the system is operating within safe parameters and identify any potential issues.
Potential Challenges and Considerations
Converting a propane smoker to natural gas isn’t always straightforward. Several potential challenges and considerations can arise.
Burner Compatibility: Some propane burners are simply not designed to function properly with natural gas, even with modifications. In these cases, you may need to replace the entire burner assembly with a natural gas-specific burner.
Ventilation: Ensure your smoker has adequate ventilation, especially if you are using it indoors or in a confined space. Poor ventilation can lead to carbon monoxide buildup, which is extremely dangerous.
Altitude: Altitude can affect the performance of gas appliances. If you live at a high altitude, you may need to adjust the gas pressure or orifice size to compensate for the thinner air.
Local Codes and Regulations: Check your local building codes and regulations regarding gas appliance conversions. Some jurisdictions may require a permit or inspection for such modifications.
