The allure of a sizzling griddle, churning out pancakes, bacon, and burgers, is undeniable. But what if you’re tired of lugging around propane tanks and yearn for the convenience of natural gas? The question then becomes: can you convert your propane griddle to run on natural gas? The answer, while not a simple yes or no, is generally yes, but it comes with caveats and considerations.
Understanding the Fuel Differences: Propane vs. Natural Gas
Before diving into the conversion process, it’s crucial to grasp the fundamental differences between propane (liquefied petroleum gas, or LPG) and natural gas. These differences dictate why a simple fuel swap is not an option and why modifications are necessary.
BTU Output: The Heat Factor
One of the most significant distinctions lies in their British Thermal Unit (BTU) content. BTU measures the amount of energy required to raise the temperature of one pound of water by one degree Fahrenheit. Propane boasts a higher BTU content per cubic foot than natural gas. This means propane packs more heat per unit volume. An average propane tank holds around 91,500 BTUs per gallon, while natural gas typically yields around 1,000 BTUs per cubic foot.
Pressure Requirements: A Matter of Flow
Fuel pressure is another critical factor. Propane appliances operate at a significantly higher pressure than natural gas appliances. A standard propane regulator delivers gas at around 11 inches of water column (WC), while natural gas typically runs at 4 inches WC. These differing pressure requirements necessitate changes to the griddle’s gas delivery system.
Orifice Size: Controlling the Fuel
The orifice, a small opening that controls the flow of gas into the burner, differs in size between propane and natural gas appliances. Propane orifices are smaller due to the higher BTU content and pressure. Natural gas orifices are larger to compensate for the lower BTU content and pressure and deliver the appropriate amount of heat.
Is Conversion Possible? Assessing Your Griddle
Whether or not you can convert your propane griddle depends on a few factors. Not all griddles are created equal, and some are simply not designed for conversion.
Manufacturer Support: The Ideal Scenario
The best-case scenario is if your griddle’s manufacturer offers a conversion kit specifically designed for your model. These kits typically include the necessary orifices, a new regulator, and detailed instructions. Using a manufacturer-approved kit ensures compatibility and safety. Contacting the manufacturer directly or checking their website is the first step.
Griddle Design: Convertibility Considerations
Some griddles are designed with conversion in mind, featuring interchangeable parts and clear instructions. Others may be more challenging or even impossible to convert safely. Look for models that have readily accessible orifices and a design that allows for easy regulator replacement.
Safety Certifications: Upholding Standards
Ensure any conversion you undertake doesn’t compromise the griddle’s safety certifications (such as CSA or UL). Altering a certified appliance can void the warranty and potentially create a safety hazard. Improper conversion can lead to gas leaks, explosions, or carbon monoxide poisoning.
The Conversion Process: A Step-by-Step Overview
If you’ve determined that your griddle is convertible and you have a suitable conversion kit, here’s a general overview of the process. It is crucial to emphasize that this is a general guideline, and you should always follow the specific instructions provided with your conversion kit and consult with a qualified professional if you’re unsure about any step.
Gathering Your Tools and Materials
Before you begin, gather all the necessary tools and materials. This typically includes:
- Conversion Kit (with orifices and regulator)
- Wrenches (various sizes)
- Screwdrivers (Phillips and flathead)
- Pipe Thread Sealant (specifically for gas lines)
- Leak Detector Solution (soap and water solution)
- Adjustable Wrench
- Safety Glasses
- Gloves
Shutting Off the Gas Supply
Safety First! Before you touch anything, completely shut off the propane tank (if you haven’t already disconnected it) or the natural gas supply line at the meter. Double-check that the gas is off before proceeding.
Accessing and Replacing the Orifices
The orifices are usually located near the burners. You’ll need to remove the griddle top and burner assembly to access them. Using the appropriate wrench, carefully unscrew the propane orifices and replace them with the natural gas orifices from the conversion kit. Ensure you tighten the new orifices securely, but avoid over-tightening.
Replacing the Regulator
The regulator controls the gas pressure entering the griddle. Locate the propane regulator and disconnect it from the gas supply line. Install the new natural gas regulator, ensuring a tight and secure connection. Use pipe thread sealant on the threads to prevent leaks.
Connecting to the Natural Gas Supply
Connect the natural gas supply line to the new regulator. Again, use pipe thread sealant on the threads to ensure a leak-proof connection.
Testing for Leaks
Once everything is connected, it’s time to test for leaks. Mix a solution of soap and water and apply it to all gas connections, including the orifices, regulator, and supply line connections. Turn on the natural gas supply and look for bubbles forming in the soapy solution. If you see bubbles, immediately turn off the gas and tighten the connection. Repeat the leak test until no leaks are detected.
Adjusting the Burner Flames
After confirming no leaks, light the burners and observe the flames. The flames should be blue with a slight yellow tip. If the flames are too yellow or orange, or if they are lifting off the burner, you may need to adjust the air shutter. The air shutter controls the amount of air mixed with the gas. Adjust it until you achieve a clean, blue flame.
Potential Problems and Troubleshooting
Even with careful planning and execution, problems can arise during the conversion process. Here are some common issues and potential solutions:
Gas Leaks
This is the most critical problem to address. If you detect a gas leak, immediately turn off the gas supply and tighten the connection. If the leak persists, call a qualified gas technician.
Low Flame Height
If the flame height is too low, it could be due to insufficient gas pressure or a partially blocked orifice. Check the gas pressure at the meter and ensure the orifices are clean and unobstructed.
Yellow or Orange Flames
Yellow or orange flames indicate incomplete combustion, often caused by insufficient air. Adjust the air shutter to increase the air intake.
Uneven Heating
Uneven heating can be caused by clogged burners or improper orifice sizing. Clean the burners thoroughly and ensure the correct orifices are installed.
When to Call a Professional
Converting a propane griddle to natural gas can be a DIY project for experienced individuals with a solid understanding of gas appliances. However, certain situations warrant professional assistance.
Lack of Experience
If you’re not comfortable working with gas lines or appliances, it’s best to leave the conversion to a qualified gas technician. Gas leaks and explosions are serious hazards, and it’s not worth risking your safety.
Complex Conversions
If your griddle requires extensive modifications or if the manufacturer doesn’t offer a conversion kit, a professional can assess the feasibility of the conversion and perform the necessary modifications safely and correctly.
Suspected Problems
If you encounter any problems during the conversion process that you’re unable to resolve, call a professional. Don’t attempt to force anything or make modifications without proper knowledge and expertise.

Can I convert any propane griddle to natural gas?
Not all propane griddles can be converted to natural gas. The suitability for conversion depends on the griddle’s design and the manufacturer’s specifications. Some griddles are specifically designed for propane only and lack the necessary components or flexibility to operate safely and efficiently on natural gas. Always check the griddle’s manual or contact the manufacturer to confirm whether a conversion kit is available or if the griddle is convertible at all.
Attempting to convert a griddle not designed for natural gas can lead to dangerous situations, including gas leaks, improper combustion, and potential explosions. Moreover, modifying a griddle in a way not approved by the manufacturer will likely void any existing warranty. Prioritize safety and consult with a qualified gas technician before attempting any conversion.
What are the key differences between propane and natural gas that necessitate a conversion?
The primary difference lies in their energy content and pressure requirements. Natural gas has a lower BTU (British Thermal Unit) rating per cubic foot than propane, meaning it produces less heat when burned. Consequently, a natural gas appliance requires a larger gas flow to generate the same amount of heat as a propane appliance. This difference necessitates adjustments to the orifices and regulator.
Furthermore, propane is stored as a liquid under high pressure, while natural gas is delivered through pipelines at a much lower pressure. Converting from propane to natural gas requires adjusting the regulator to accommodate the lower input pressure of natural gas. Failure to do so would result in insufficient gas flow, leading to a weak flame and poor heating performance.
What does a typical propane to natural gas conversion kit include?
A standard conversion kit usually includes a set of natural gas orifices, a new or adjustable gas regulator, and detailed installation instructions. The orifices are specifically sized for natural gas to allow the correct flow rate for optimal combustion. The regulator is essential for reducing the higher pressure of propane down to the lower pressure required by natural gas.
Depending on the griddle model, the kit may also contain tools needed for the conversion, such as wrenches or screwdrivers, as well as warning labels to indicate the griddle has been converted to natural gas. Always use a conversion kit specifically designed for your griddle model, as using generic parts can compromise safety and performance.
Can I perform the conversion myself, or do I need a professional?
While some handy individuals may be tempted to perform the conversion themselves, it is strongly recommended to hire a qualified gas technician. Working with gas appliances can be extremely dangerous if not done correctly. Improper connections or adjustments can lead to gas leaks, fire hazards, and carbon monoxide poisoning.
A certified technician has the necessary knowledge, experience, and tools to safely and properly convert your propane griddle to natural gas. They can ensure all connections are secure, the gas pressure is properly regulated, and the griddle is operating safely and efficiently. Hiring a professional provides peace of mind and ensures compliance with local codes and regulations.
What are the potential dangers of an improperly converted propane griddle?
An improperly converted griddle presents several serious safety risks. A major concern is gas leakage, which can lead to fire or explosion. If the orifices are not properly sized or the regulator is not correctly adjusted, the griddle may not burn fuel efficiently, leading to incomplete combustion and the production of carbon monoxide.
Carbon monoxide is a colorless, odorless, and poisonous gas that can cause serious health problems or even death. Other potential dangers include overheating due to improper flame control, which could damage the griddle or surrounding materials. Therefore, ensure the conversion is performed by a professional who can verify the griddle’s safety and functionality.
How can I identify if my griddle is running on natural gas after the conversion?
There are several visual and performance indicators. First, check for a blue, steady flame. A yellow or orange flame indicates incomplete combustion, suggesting a problem with the gas mixture. Listen for a consistent, even burning sound; unusual hissing or popping noises can be signs of leaks or improper gas flow.
Also, verify that the griddle heats up to the expected temperature in a reasonable amount of time. If the griddle struggles to reach the desired temperature or heats unevenly, it might indicate that the gas pressure or orifice size needs adjustment. Finally, a label indicating the conversion to natural gas should be prominently displayed on the griddle.
Will converting void my griddle’s warranty?
Yes, in most cases, converting a propane griddle to natural gas will void the manufacturer’s warranty, especially if the conversion is not performed by an authorized technician or if a non-approved conversion kit is used. Manufacturers design their products to operate specifically with the fuel type specified in the manual.
Altering the fuel system, even with a conversion kit, changes the intended operating parameters and can compromise the griddle’s performance and safety. Before proceeding with a conversion, carefully review the warranty terms and conditions or contact the manufacturer to understand the implications. If maintaining the warranty is important, consider purchasing a griddle specifically designed for natural gas.
