How to Convert Generac Generator to Natural Gas: A Step-by-Step Tutorial

Tired of the hassle and expense of propane? Looking for a more cost-effective and environmentally friendly fuel option for your Generac generator? Converting your Generac generator to natural gas can be a smart move. This guide will walk you through the process step-by-step, empowering you to make the switch with confidence.

Why Choose Natural Gas?

Natural gas offers several advantages over propane:

• Cost-effectiveness: Natural gas is often cheaper than propane, especially in areas with readily available natural gas infrastructure.
• Convenience: Natural gas is delivered directly to your home, eliminating the need for refilling tanks.
• Environmental benefits: Natural gas burns cleaner than propane, resulting in lower emissions.

Assessing Your Generac Generator

Before diving into the conversion process, it’s crucial to determine if your Generac generator is compatible with natural gas. Here’s what to check:

• Model compatibility: Not all Generac models are designed for natural gas operation. Consult your owner’s manual or contact Generac customer support to confirm compatibility.
• Engine type: The engine type plays a crucial role in conversion compatibility. Generac generators with liquid propane (LP) gas engines are generally compatible with natural gas conversion.
• Gas supply: Ensure you have access to a natural gas line near your generator. If not, you’ll need to consider the cost and feasibility of extending the line.

Gathering the Necessary Materials

Once you’ve confirmed compatibility, gather the following materials for the conversion:

• Natural gas conversion kit: This kit includes the specific components necessary for your generator model. Order the kit directly from Generac or a reputable authorized dealer.
• Natural gas regulator: This device regulates the pressure of the natural gas entering the generator. Choose a regulator specifically designed for your generator model.
• Gas line tubing: Use high-quality, flexible gas line tubing to connect the regulator to the generator.
• Gas line fittings: These fittings are essential for connecting the tubing to the regulator and generator.
• Safety equipment: Include safety glasses, gloves, and a fire extinguisher for protection during the conversion process.

The Conversion Process: A Step-by-Step Guide

Now, let’s break down the conversion process into manageable steps:
1. Shut off the gas supply: Locate the gas valve for your propane tank and turn it off.
2. Disconnect the propane lines: Carefully disconnect the propane lines from the generator, noting the connections for reassembly.
3. Install the natural gas conversion kit: Follow the manufacturer’s instructions for installing the conversion kit. This typically involves replacing the existing propane regulator with the natural gas regulator and connecting the new gas lines.
4. Connect the natural gas line: Run the gas line tubing from the natural gas line to the regulator, ensuring secure connections with the appropriate fittings.
5. Test for leaks: Once the connections are complete, carefully test for any gas leaks using a leak detector solution. If you detect any leaks, tighten the connections or consult a professional.
6. Start the generator: Turn on the natural gas supply and start the generator. If the generator runs smoothly, you’ve successfully converted it to natural gas.

Safety Precautions: Prioritizing Your Well-being

Safety should always be your top priority during the conversion process. Here are some essential precautions to keep in mind:

• Work in a well-ventilated area: Ensure adequate ventilation to prevent the buildup of potentially harmful gases.
• Avoid open flames: Keep any open flames away from the generator and the gas lines during the conversion process.
• Follow manufacturer instructions: Always adhere to the manufacturer’s instructions for installing the conversion kit and connecting the gas lines.
• Seek professional help if needed: If you’re uncomfortable with any part of the conversion process, don’t hesitate to contact a qualified technician for assistance.

Choosing the Right Conversion Kit: Ensuring Compatibility

Selecting the correct conversion kit is crucial for a successful and safe conversion. Here’s how to ensure you choose the right one:

• Verify compatibility: Confirm that the kit is specifically designed for your Generac model and engine type.
• Check the manufacturer’s specifications: Ensure the kit’s specifications match your generator’s requirements.
• Purchase from a reputable source: Buy your conversion kit from a reputable authorized Generac dealer or a trusted online retailer.

Post-Conversion Maintenance: Keeping Your Generator Running Smoothly

Once you’ve converted your generator to natural gas, it’s essential to perform regular maintenance to ensure optimal performance and longevity. Here are some key maintenance tips:

• Inspect the gas lines: Regularly check the gas lines for any signs of damage, leaks, or corrosion.
• Clean the air filter: A clean air filter is crucial for efficient combustion. Replace or clean the filter as recommended by the manufacturer.
• Change the oil: Change the generator’s oil at the intervals specified in the owner’s manual.
• Inspect the spark plugs: Regularly inspect and replace the spark plugs as needed.

Final Thoughts: Fueling Efficiency and Sustainability

Converting your Generac generator to natural gas offers a compelling solution for reducing operating costs and minimizing your environmental impact. By following this comprehensive guide, you can confidently navigate the conversion process and reap the benefits of cleaner, more cost-effective fuel.
