Converting a smoker from one fuel source to another can seem daunting, but it’s a common modification for those seeking convenience or cost savings. Specifically, converting a Masterbuilt smoker to natural gas is a popular query. Let’s delve into whether this is feasible, what’s involved, and the potential challenges.
Understanding Masterbuilt Smokers and Fuel Types
Masterbuilt is a well-known brand specializing in electric and propane smokers. Electric smokers offer push-button convenience, while propane smokers provide portability and higher temperatures. Natural gas, on the other hand, is generally cheaper than propane in many regions, and for homeowners with existing natural gas lines, it offers a continuous and readily available fuel source.
The critical difference between propane and natural gas lies in their pressure and BTU (British Thermal Unit) output. Propane operates at a much higher pressure than natural gas and delivers more BTUs per cubic foot. This disparity is crucial because it affects the design of the burner and regulator system.
Propane vs. Natural Gas: Key Differences
The primary difference lies in the pressure and energy content. Propane typically operates at around 11 inches of water column (WC) pressure, while natural gas operates at a much lower pressure, typically around 4 inches WC. This difference means that the orifices (the small holes that release the gas) in propane burners are significantly smaller than those used in natural gas burners.
BTU output is also a factor. Propane has a higher BTU content per unit volume than natural gas. Therefore, a burner designed for propane will not provide the same heat output when used with natural gas unless modifications are made.
Why Convert to Natural Gas?
Homeowners often consider converting to natural gas for several compelling reasons:
- Cost Savings: Natural gas is frequently cheaper than propane, leading to long-term savings.
- Convenience: Connecting to an existing natural gas line eliminates the need to refill propane tanks.
- Consistent Fuel Supply: You’ll never run out of fuel mid-cook with a natural gas connection.
Is Conversion Possible? The Technical Aspects
The short answer is yes, converting a Masterbuilt smoker to natural gas is technically possible, but it’s not a straightforward swap and requires careful consideration and potentially specialized parts. It’s crucial to understand that Masterbuilt does not officially support or endorse such conversions.
Burner and Orifice Size
The most critical component to address is the burner itself. A propane burner is designed for high-pressure propane and has a small orifice. To use natural gas, you’ll likely need to replace the burner with one designed for natural gas, or at least significantly enlarge the existing orifice. Simply drilling out the propane orifice is not recommended due to the difficulty in achieving the precise size required for safe and efficient combustion.
The correct orifice size is crucial for safety and performance. An incorrectly sized orifice can lead to a dangerous gas leak, incomplete combustion (producing carbon monoxide), or insufficient heat output.
Regulator Requirements
Propane regulators reduce the high pressure of the propane tank to a usable level for the burner. Natural gas already has a lower pressure, so a different regulator (or no regulator, depending on your gas line pressure) will be required. Matching the regulator to the appropriate gas pressure and BTU rating of the burner is essential.
Safety Considerations
Working with natural gas is inherently dangerous. Leaks can lead to explosions or carbon monoxide poisoning. If you’re not comfortable working with gas lines and regulators, it’s strongly recommended to hire a qualified gas technician. They can ensure the conversion is done safely and according to local codes.
Potential Challenges and Risks
Even with the correct parts, converting a Masterbuilt smoker to natural gas can present challenges:
- Warranty Voidance: Modifying your smoker will likely void the manufacturer’s warranty.
- Finding Compatible Parts: Aftermarket natural gas burners specifically designed for Masterbuilt smokers may be difficult to find. You might need to adapt burners intended for other appliances.
- Precise Adjustments: Fine-tuning the gas flow and air mixture is critical for optimal performance. This often requires experimentation and specialized knowledge.
- Local Codes and Regulations: Be sure to check local building codes and regulations regarding natural gas appliance installations. Permits may be required.
- Incomplete Combustion: If the conversion is not performed correctly, incomplete combustion may occur. This results in producing carbon monoxide, a deadly gas.
Steps Involved in a Theoretical Conversion
While we strongly recommend professional assistance, understanding the general steps involved can help you evaluate the complexity of the project.
Step 1: Assess Your Smoker Model
Identify the exact model of your Masterbuilt smoker. This information is crucial for researching potential burner replacements or modifications.
Step 2: Research Natural Gas Burner Options
Look for aftermarket natural gas burners that are compatible with your smoker’s dimensions and BTU requirements. You may need to search for burners intended for similar-sized grills or cookers.
Step 3: Acquire Necessary Parts
Gather all the necessary components, including:
- A natural gas burner with the correct BTU rating.
- A natural gas regulator suitable for your gas line pressure.
- Appropriate fittings and connectors for gas lines.
- Pipe sealant designed for natural gas.
- A gas leak detector.
Step 4: Disconnect the Propane System (If Applicable)
If your smoker is currently set up for propane, carefully disconnect the propane tank and regulator. Ensure the propane line is completely sealed off.
Step 5: Install the Natural Gas Burner
Mount the natural gas burner in place of the existing propane burner. You may need to fabricate mounting brackets or modify the smoker’s frame to ensure a secure fit.
Step 6: Connect the Natural Gas Line and Regulator
Connect the natural gas regulator to your natural gas supply line, using appropriate fittings and pipe sealant. Ensure all connections are tight and leak-free.
Step 7: Test for Gas Leaks
Using a gas leak detector or soapy water, check all gas line connections for leaks. If you detect any leaks, immediately turn off the gas supply and tighten the connections.
Step 8: Adjust the Air Shutter
Most natural gas burners have an air shutter that controls the amount of air mixed with the gas. Adjust the air shutter to achieve a clean, blue flame. Too much air will cause the flame to lift off the burner, while too little air will cause a yellow, sooty flame.
Step 9: Test the Smoker
Once you’re confident that the conversion is safe and leak-free, test the smoker by running it at various temperature settings. Monitor the temperature and adjust the gas flow as needed to achieve the desired cooking temperature.
Alternative Solutions
If a full conversion seems too risky or complex, consider these alternatives:
- Use a Propane Tank Refill Station: Refilling propane tanks at a refill station is often cheaper than exchanging them.
- Invest in a Natural Gas Grill or Smoker: If you primarily want to cook with natural gas, consider purchasing a dedicated natural gas grill or smoker. This eliminates the risks associated with conversion.
- Upgrade to a Larger Propane Tank: Using a larger propane tank can reduce the frequency of refills.
Safety First: A Repeated Emphasis
We cannot overemphasize the importance of safety when working with natural gas. Natural gas is flammable and potentially explosive. Incorrectly installed gas lines can leak, leading to fires, explosions, or carbon monoxide poisoning.
If you are not comfortable working with gas lines, hire a qualified gas technician to perform the conversion. A professional will have the knowledge, experience, and tools to ensure the job is done safely and according to local codes.
Attempting a conversion without the proper knowledge and precautions could put yourself and your family at risk.
The Verdict: Proceed with Extreme Caution
Converting a Masterbuilt smoker to natural gas is possible but comes with significant challenges and risks. It requires careful planning, specialized parts, and a thorough understanding of gas line safety. Unless you are a qualified gas technician, we strongly recommend against attempting this conversion yourself. The potential cost savings and convenience may not be worth the safety risks. Consider alternative solutions, such as using a propane refill station or investing in a dedicated natural gas grill or smoker. Always prioritize safety when working with gas appliances.
