Grilling enthusiasts often debate the merits of propane versus natural gas grills. Propane offers portability, while natural gas provides a continuous, potentially cheaper fuel source directly connected to your home. If you own a Char-Broil Advantage grill, you might be wondering: Can I convert it to natural gas? This article will delve into the complexities of converting your Char-Broil Advantage grill, covering safety, feasibility, necessary parts, and potential challenges. We will explore the pros and cons of each fuel type, compatibility issues, and provide a step-by-step approach to evaluating whether a conversion is right for you.
Understanding the Fuel Difference: Propane vs. Natural Gas
Propane and natural gas are both hydrocarbon fuels, but they differ significantly in composition, pressure, and energy content.
Propane, or liquefied petroleum gas (LPG), is a byproduct of natural gas processing and crude oil refining. It’s stored under pressure as a liquid, making it easily transportable in tanks. Natural gas, primarily methane, is extracted directly from the earth and delivered through pipelines.
The key difference lies in their energy content per volume unit and the pressure at which they are delivered. Propane has a higher BTU (British Thermal Unit) content per cubic foot than natural gas. This means propane burns hotter and requires smaller orifices (the small openings in the burners) for the same amount of heat output. Natural gas is delivered at a much lower pressure than propane. Propane typically operates at 11 inches of water column pressure, while natural gas operates at around 4 inches.
These fundamental differences are critical when considering a fuel conversion. Simply connecting a natural gas line to a grill designed for propane will result in a weak, inefficient flame.
Assessing the Feasibility of Conversion: Is It Even Possible?
The first step is determining if your specific Char-Broil Advantage model is convertible. Not all grills are designed for conversion. Some manufacturers explicitly state in their user manuals that their grills are not convertible, and attempting to do so could void the warranty or, more importantly, create a safety hazard.
Check your Char-Broil Advantage grill’s manual or the Char-Broil website for your model number and look for information regarding natural gas conversion. If the manual mentions a conversion kit or provides instructions for converting to natural gas, you’re in luck. If it explicitly states “not convertible,” it’s best to heed that warning.
If the manual is unclear, contact Char-Broil’s customer support directly. They can provide specific information about your model and whether a conversion kit is available or recommended. Be prepared to provide your grill’s model number and any other relevant identifying information.
Even if a conversion kit exists, consider the cost. Conversion kits can be expensive, sometimes costing nearly as much as a new natural gas grill. Factor in the cost of the kit, any professional installation fees, and the cost of running a natural gas line to your grilling area.
Identifying the Necessary Parts and Tools for Conversion
If your Char-Broil Advantage grill is convertible and you’ve decided to proceed, you’ll need a conversion kit and some basic tools.
A typical natural gas conversion kit will include:
- A new regulator: This regulator is designed to handle the lower pressure of natural gas. It will replace the propane regulator currently on your grill.
- Natural gas orifices: These are smaller than propane orifices and restrict the flow of natural gas to the burners.
- A flexible gas line: This connects the grill to your natural gas supply.
- Instructions: Detailed instructions specific to your grill model.
Tools you’ll likely need include:
- Adjustable wrench
- Screwdrivers (Phillips and flathead)
- Pipe wrench
- Leak detector solution (soap and water mixture)

While some grills are designed for conversion or come with conversion kits, the Char-Broil Advantage series generally isn’t designed for direct conversion. Char-Broil typically advises against converting their propane grills to natural gas due to differences in gas pressure and burner orifice size. Converting a grill not designed for it can lead to unsafe operation, including gas leaks, inconsistent flames, and potential damage to the grill.
If you’re considering using natural gas, the safest and most reliable approach is to purchase a grill specifically designed and approved for natural gas use. These grills have the correct components and safety features to operate efficiently and safely with natural gas. Look for models that clearly state they are natural gas compatible or offer a natural gas version.
What are the risks of converting a Char-Broil Advantage propane grill to natural gas?
Converting a propane grill to natural gas without the proper components and expertise poses significant safety risks. Natural gas operates at a lower pressure than propane, requiring larger burner orifices to achieve the same heat output. Using the smaller propane orifices with natural gas will result in a weak flame and insufficient heating. Conversely, improperly enlarging the orifices can lead to excessive gas flow and a dangerous, uncontrollable flame.
Beyond flame control issues, converting a grill not designed for it voids any existing warranty and creates a potential fire hazard. Improperly installed gas lines and connections can leak, leading to an explosion. It’s crucial to prioritize safety and adhere to manufacturer guidelines when dealing with flammable gases. Engaging a qualified gas technician is always recommended before undertaking any gas-related modifications.
What modifications would be necessary to convert a Char-Broil Advantage grill to natural gas?
Converting a Char-Broil Advantage propane grill to natural gas would require several modifications. The primary change involves replacing the propane regulator and hose with a natural gas regulator and hose designed for the lower gas pressure. The burner orifices would need to be significantly enlarged or replaced with natural gas-specific orifices to allow for the increased gas flow needed to generate adequate heat.
Furthermore, the venturi tubes that mix the gas and air might need adjustment or modification to ensure proper combustion. These adjustments are crucial for achieving a clean and efficient flame. Without these changes, the grill will likely produce a weak flame, uneven heating, and potentially dangerous carbon monoxide emissions. Obtaining the correct components and performing these modifications correctly requires significant expertise and access to specialized tools.
Are there any Char-Broil conversion kits available for the Advantage series?
Char-Broil does not typically offer conversion kits specifically designed for converting their Advantage series propane grills to natural gas. Their official stance is generally against converting models not explicitly designed for it. The lack of conversion kits reflects the inherent design differences between propane and natural gas grills, which necessitate more than just a simple regulator change.
While some aftermarket universal conversion kits might be available, using them on a Char-Broil Advantage grill is generally not recommended. These kits are often generic and may not be compatible with the specific burner design and gas flow characteristics of your grill. Using a non-approved kit can compromise safety and void your grill’s warranty. Always consult the manufacturer’s recommendations before considering any conversion.
What are the BTU differences between propane and natural gas, and how does this affect a conversion?
Propane and natural gas have different British Thermal Unit (BTU) contents per volume. Propane has a higher BTU content than natural gas. Specifically, one cubic foot of propane produces approximately 2,500 BTUs, while one cubic foot of natural gas produces approximately 1,000 BTUs. This BTU difference necessitates different burner orifice sizes and regulator pressures.
When converting from propane to natural gas, the burners need to deliver a higher volume of natural gas to achieve the same heat output as propane. This is why the burner orifices must be larger for natural gas grills. Failing to account for this BTU difference will result in a significantly underpowered grill that cannot reach desired cooking temperatures.
If I still want to convert my grill, what precautions should I take?
If you are determined to convert your Char-Broil Advantage grill despite the manufacturer’s recommendation, proceed with extreme caution. First, consult with a licensed and qualified gas technician. They can assess the feasibility of the conversion and advise on the necessary components and modifications to ensure safe operation. Do not attempt the conversion yourself unless you possess the required knowledge and expertise.
Ensure that all gas connections are properly tightened and leak-tested using a soap and water solution. After the conversion, carefully monitor the flame characteristics, looking for any signs of instability or excessive soot production. It is strongly advised to have the converted grill inspected by the gas technician before the first use. Remember that any modifications are at your own risk and may void the warranty.
What are the alternatives to converting my propane Char-Broil Advantage grill to natural gas?
The safest and most reliable alternative to converting your existing propane grill is to purchase a new grill specifically designed for natural gas. Natural gas grills are engineered with the correct burner orifices, regulators, and safety features to operate efficiently and safely with natural gas. This eliminates the risks associated with modifying a propane grill.
Another alternative is to simply continue using propane. While propane tanks require refilling, they offer portability that a natural gas grill, connected to a gas line, does not. You can invest in a larger propane tank or explore propane tank exchange programs for convenient refueling options. Ultimately, sticking with propane eliminates the complexities and potential dangers of a conversion.
