The Possibility of Using Natural Gas with a Dual Fuel Generator

Dual fuel generators offer the advantage of being able to run on both propane and gasoline, providing flexibility in fuel options. However, many users want to know if it is possible to run these generators on natural gas as well. This article will explore the possibility of using natural gas with a dual fuel generator, including the necessary components and steps involved in making it work.

Understanding Dual Fuel Generators

Dual fuel generators are designed to be compatible with both propane and gasoline. They come with a regulator that ensures the correct pressure for the generator to operate efficiently. However, the type of regulator included with the generator determines its compatibility with natural gas.

Different Types of Regulators

Some dual fuel generators come with an on-demand or load regulator, which allows for the use of natural gas. These generators can be converted into a tri-fuel unit by purchasing a conversion kit. Other dual fuel generators have a mounted load regulator, which restricts the use of natural gas. Bypassing this regulator would void the warranty and is not recommended.

Determining Compatibility with Natural Gas

To determine if a dual fuel generator is compatible with natural gas, it is necessary to inspect its internal components. By removing the side panel, the presence of a specific hose connected to the carburetor can indicate the potential for natural gas usage. If the generator has a mounted load regulator, it cannot run on natural gas without modifications.

Bypassing Load Regulators

For dual fuel generators with a mounted load regulator, bypassing the regulator is required to enable the use of natural gas. This involves running a new hose directly from the other side of the generator into the carburetor and utilizing a tri-fuel conversion kit. It is important to note that modifying the internal components of the generator will void the warranty.

Purchasing a Tri-Fuel Kit

Once compatibility with natural gas has been determined, a tri-fuel conversion kit must be purchased. These kits, such as the ones offered by Sentry, provide the necessary fittings and hoses to facilitate the use of natural gas. It is recommended to consult with local regulations and utility companies to ensure proper installation.

Installing the Tri-Fuel Kit

To install the tri-fuel kit, a half-inch natural gas line should be run from an appropriate distance away from the house to the load regulator. The load regulator should be positioned within three feet of the generator for optimal performance. After installation, it is crucial to test for any gas leaks using the soap and water method or a gas detector.

Adjusting the Load Block

Once the conversion kit is installed, adjustments may need to be made to the load block. This is done while the generator is running under a load, and the load is gradually increased until reaching the desired level. Adjustments are made by turning the load block in or out to achieve the smooth operation of the generator.

Conclusion

In conclusion, running a dual fuel generator on natural gas is possible with the right components and modifications. By understanding the type of regulator and internal setup of the generator, users can determine if it is feasible to use natural gas. Proper installation of a tri-fuel kit and adjustment of the load block are essential for optimal performance. Always consult local regulations and utility companies before making any modifications to ensure compliance and safety.

• Dual fuel generators offer flexibility with fuel options.
• The type of regulator determines compatibility with natural gas.
• Bypassing load regulators can enable the use of natural gas.
• Tri-fuel conversion kits provide the necessary components for natural gas usage.
• Proper installation and testing for leaks are crucial for safety.
• Adjusting the load block ensures smooth operation under a load.

FAQ

Q: Can I run a dual fuel generator on natural gas without modifications? A: It depends on the type of regulator and internal setup of the generator. Some dual fuel generators come with an on-demand regulator that allows for natural gas usage, while others require modifications to bypass the load regulator.

Q: Will modifying my generator to run on natural gas void the warranty? A: Yes, modifying the internal components of a generator, especially bypassing the load regulator, will likely void the warranty. It is important to consider this before making any modifications.

Q: How can I test for gas leaks after installing a tri-fuel kit? A: Gas leaks can be tested using the soap and water method. Apply a soapy solution to all connections and observe for any bubbles. Alternatively, a gas detector can be used to detect the presence of gas.

Q: What is the purpose of adjusting the load block? A: The load block adjustment allows for fine-tuning the fuel mixture and controlling the generator's performance under a load. It ensures the generator runs smoothly and efficiently on natural gas.
