Blackstone grills, renowned for their versatility and ability to cook everything from breakfast pancakes to seared steaks, are a staple in many outdoor kitchens. The convenience of propane is undeniable, but many grill masters crave the consistent and often more cost-effective fuel source of natural gas. But is converting your Blackstone grill to natural gas a feasible option? Let’s delve into the details.
Understanding the Basics: Propane vs. Natural Gas
Propane and natural gas, while both used for grilling, are fundamentally different fuels. Propane is a liquefied petroleum gas (LPG), stored under pressure as a liquid, while natural gas is primarily methane, existing as a gas at standard temperatures and pressures. This difference in state and composition affects their energy density and the pressure at which they are delivered and burned.
Energy Content and Pressure Differences
Propane boasts a higher energy content per unit volume compared to natural gas. This is why propane tanks are smaller but still provide considerable grilling time. Conversely, natural gas is typically delivered through pipelines at a lower pressure than propane. Therefore, a direct swap between fuel sources would result in either an insufficient flame with natural gas or a dangerously large flame with propane.
Why Convert to Natural Gas? Potential Benefits
Despite the differences, converting to natural gas can be attractive for several reasons.
- Cost Savings: Natural gas is often cheaper than propane, especially if you have an existing natural gas line to your home. The savings can add up over time, particularly for frequent grillers.
- Convenience: No more running out of propane mid-cookout! Natural gas provides a continuous fuel supply, eliminating the need for tank refills or exchanges.
- Environmental Considerations: Natural gas combustion produces slightly less carbon dioxide than propane, potentially making it a marginally greener option.
Blackstone and Natural Gas: The Official Stance
Blackstone’s official position on converting their grills to natural gas varies depending on the model. Many Blackstone grills are designed to operate exclusively on propane. Attempting to use natural gas with these models without proper modification is unsafe and will likely void any warranty.
Checking Your Specific Model
The first step is to consult your Blackstone grill’s manual or the manufacturer’s website. Look for information regarding fuel type compatibility. The manual will explicitly state whether your grill is designed for propane only, natural gas only, or convertible between the two. Some newer Blackstone models are designed to be convertible with the appropriate conversion kit.
Conversion Kits: What Are They and What Do They Do?
If your Blackstone grill is designed to be convertible, you will need a specific natural gas conversion kit. These kits typically include a new regulator, orifices, and sometimes a hose. The regulator is crucial for reducing the higher natural gas pressure to a level suitable for the grill’s burners. The orifices are small, precisely sized nozzles that control the flow of gas to each burner. Using the incorrect orifice size can lead to improper combustion, resulting in a weak flame, excessive fuel consumption, or a dangerous situation.
The Conversion Process: A Step-by-Step Overview
Converting a Blackstone grill to natural gas is not a task to be taken lightly. It involves working with flammable gas, and any mistakes can have serious consequences. If you are not comfortable working with gas lines and regulators, it is strongly recommended to hire a qualified professional.
Gathering the Necessary Tools and Materials
Before starting, gather the following:
- Natural gas conversion kit specific to your Blackstone grill model.
- Adjustable wrench.
- Pipe wrench.
- Screwdrivers (Phillips and flathead).
- Leak detector solution (soap and water mixture).
- Gloves.
- Safety glasses.
Shutting Off the Gas Supply
The first and most crucial step is to shut off the gas supply completely. Locate the main gas shut-off valve for your natural gas line and turn it off. Then, disconnect the propane tank from your Blackstone grill and ensure it is stored safely away from the work area.
Replacing the Regulator
Carefully disconnect the propane regulator from the grill. Install the new natural gas regulator from the conversion kit, ensuring a tight and secure connection. Use pipe dope or Teflon tape on the threads to prevent leaks.
Changing the Orifices
Each burner on your Blackstone grill has an orifice that controls the gas flow. You must replace the propane orifices with the natural gas orifices included in the conversion kit. These orifices are typically located at the base of each burner. Use a wrench or socket to carefully remove the old orifices and install the new ones. Make sure each orifice is properly tightened.
Connecting to the Natural Gas Line
Connect the natural gas hose from the conversion kit to your home’s natural gas supply line. Again, use pipe dope or Teflon tape on the threads to ensure a leak-proof seal. Tighten the connection securely with a wrench.
Leak Testing
After completing the conversion, it is imperative to test for leaks. Mix a solution of soap and water and apply it to all gas connections, including the regulator, orifices, and hose connections. Turn on the natural gas supply slowly and carefully. If you see bubbles forming at any connection, there is a leak. Immediately shut off the gas supply and tighten the connection until the leak stops. Repeat the leak test until all connections are leak-free.
Adjusting the Burner Flames
Once you are confident that there are no leaks, turn on the grill and observe the burner flames. The flames should be blue with a slight yellow tip. If the flames are yellow or orange, it indicates incomplete combustion, which can produce carbon monoxide. Adjust the air shutter on the burner until the flames are blue and stable.
Potential Risks and Safety Precautions
Converting a Blackstone grill to natural gas is not without its risks. Working with gas requires caution and attention to detail.
- Gas Leaks: As mentioned earlier, gas leaks can be extremely dangerous. Always perform a thorough leak test after completing the conversion.
- Improper Combustion: Incorrect orifice sizes or improper air shutter adjustments can lead to incomplete combustion, producing carbon monoxide. Carbon monoxide is a colorless, odorless gas that can be fatal. Ensure proper ventilation when using the grill and install a carbon monoxide detector in your home.
- Damage to the Grill: Attempting to convert a grill that is not designed for natural gas can damage the burners, regulator, or other components. Always check the manufacturer’s instructions before attempting any conversion.
- Voiding the Warranty: Performing an unauthorized conversion may void your Blackstone grill’s warranty.
Alternatives to Conversion
If converting your Blackstone grill to natural gas seems too risky or complicated, there are alternatives to consider.
- Using a Larger Propane Tank: A larger propane tank will reduce the frequency of refills.
- Purchasing a Grill Designed for Natural Gas: If you are set on using natural gas, consider purchasing a grill specifically designed for it. This eliminates the need for conversion and ensures safe and efficient operation.
- Propane Tank Level Monitoring Systems: Devices are available that monitor your propane tank level and alert you when it is getting low, preventing unexpected run-outs.
Troubleshooting Common Issues After Conversion
Even after a careful conversion, you might encounter some issues. Here are a few common problems and potential solutions:
- Weak Flame: This could indicate insufficient gas pressure. Double-check the regulator and ensure it is functioning correctly. Also, verify that the natural gas supply is adequate.
- Yellow or Orange Flames: This indicates incomplete combustion. Adjust the air shutter until the flames are blue with a slight yellow tip.
- Uneven Heating: This could be due to clogged burners or uneven gas flow. Clean the burners and check the orifice alignment.
