Many backyard chefs love their propane grills but dream of the convenience of natural gas. Hooking up a grill to a permanent natural gas line means no more refilling tanks! But a common question pops up: Can Any Propane Grill Be Converted To Natural Gas?
It can seem tricky for beginners. Don’t worry, we’ll walk you through it with simple steps so you can make the switch easily. Let’s see what’s possible.
Converting Propane Grills To Natural Gas What You Need To Know
Is It Possible To Convert A Propane Grill To Natural Gas
Yes, in many cases, it is possible to convert a propane grill to run on natural gas. However, it’s not a simple swap for every single grill. The main difference lies in how the gas is delivered and used by the grill’s burners. Propane is a heavier gas stored under pressure in a tank, while natural gas is a lighter gas delivered through underground pipelines at lower pressure. This difference in pressure and density means you can’t just attach a natural gas hose to a propane grill and expect it to work correctly or safely.
Understanding Gas Pressures And Types
Propane tanks store liquefied petroleum gas (LPG) at high pressure. When you turn on your propane grill, a regulator reduces this pressure to a usable level for the burners. Natural gas, on the other hand, comes from your home’s gas line at a much lower pressure. This means that the components of a propane grill, particularly the orifices that control the gas flow into the burners, are designed for a higher pressure and a different gas density.
Orifices The Key Difference
The small openings that let gas into your grill’s burners are called orifices or jets. These are precisely sized for the type of gas they’re meant to use. For propane, these orifices are smaller because propane is denser and needs less volume to produce the same heat output compared to natural gas. If you try to run a propane grill on natural gas without changing these orifices, the grill will receive too little gas and produce a weak, ineffective flame, or it might not light at all.
Burner Design And Air Mix
Beyond the orifices, the design of the burners themselves can play a role. Burners are designed to mix air with the fuel gas to create the right kind of flame. Natural gas and propane have different combustion characteristics. Some grill burners are designed to work with both gases, while others are specifically made for one or the other. A conversion kit will typically include new orifices and sometimes adjustments for the air shutter to ensure a proper air-fuel mix for natural gas.
What Grills Can Be Converted
The ability to convert a propane grill to natural gas depends heavily on the grill’s design and whether a manufacturer-approved conversion kit is available.
Manufacturer Supported Conversions
Many reputable grill manufacturers design their grills to be convertible. They often sell specific conversion kits for their propane models that allow them to be safely and efficiently used with natural gas. These kits include all the necessary parts, such as new orifices, a longer gas hose designed for natural gas, and instructions. If a manufacturer offers a conversion kit for your specific grill model, this is by far the safest and most reliable way to convert.
Universal Conversion Kits
There are also “universal” conversion kits available. However, these can be riskier. They might provide generic orifices that might not be perfectly matched to your grill’s burners. Using a poorly matched orifice could lead to inefficient burning, uneven heat, or even safety hazards like excessive carbon monoxide production. It’s always best to try and find a kit designed for your specific grill model or brand.
Grills Not Designed For Conversion
Some grills, especially lower-end or older models, might not be designed for conversion at all. They might have sealed components or burner designs that make a safe and effective conversion impossible. Attempting to force a conversion on a grill not meant for it can be dangerous and could damage the grill beyond repair.
How To Convert Your Propane Grill To Natural Gas A Step-By-Step Guide
Converting your grill involves several important steps. Safety is paramount throughout the entire process.
Step 1 Check Your Grill’s Compatibility
Before you buy anything, find out if your grill is designed for conversion.
Check the grill’s manual or the manufacturer’s website.
Look for information on conversion kits or natural gas compatibility.
If the manufacturer doesn’t offer a kit or mention conversion, it might be best to reconsider.
Step 2 Purchase The Correct Conversion Kit
Once you confirm your grill can be converted, get the right kit.
Ensure the kit is made for your specific grill model and brand.
A quality kit will include:
New orifices for each burner.
A longer gas hose suitable for natural gas.
Sometimes an air shutter adjustment part.
Clear, detailed instructions.
Step 3 Gather Your Tools
You’ll need basic tools for the job.
Screwdrivers (Phillips and flathead).
Adjustable wrench.
Pliers.
Work gloves.
Safety glasses.
A gas leak detection solution (soapy water works).
Step 4 Prepare Your Grill And Work Area
Safety first.
Make sure the grill is completely cool.
Disconnect the propane tank.
Move the grill to a well-ventilated outdoor area.
Ensure you have access to your home’s natural gas line outlet.
Step 5 Replace The Orifices
This is a critical step.
Carefully remove the burner covers and heat shields.
Locate the orifices at the base of each burner tube. They are usually brass screws with a tiny hole in the center.
Use a wrench to unscrew the old propane orifices.
Screw in the new natural gas orifices from your conversion kit. Make sure they are snug but don’t overtighten.
Step 6 Connect The Natural Gas Hose
Your conversion kit will come with a new hose.
Disconnect the old propane regulator and hose from the grill’s manifold.
Connect the new natural gas hose to the manifold. Follow the kit’s instructions for proper connection.
Connect the other end of the natural gas hose to your home’s natural gas outlet.
Step 7 Check For Leaks
This is the most important safety step.
Turn on the natural gas supply at your home’s outlet.
Gently turn on one of the grill’s control knobs to let a small amount of gas flow.
Spray the soapy water solution on all the connections you made, including where the hose connects to the grill and the gas outlet.
Look for bubbles forming. If you see bubbles, there’s a leak. Turn off the gas immediately and tighten the connection, then test again.
Repeat this for all burners and connections.
Step 8 Test The Grill
Once you’re sure there are no leaks, test the grill.
Turn on the natural gas supply.
Light each burner one at a time.
Observe the flame. It should be blue with yellow tips and have a consistent height.
A weak or flickering flame might indicate a problem with the orifices or air mix.
Step 9 Make Adjustments If Needed
If the flame looks off, you might need to adjust the air shutters.
Some kits come with instructions for this.
Improper flame can lead to poor cooking performance or carbon monoxide.
Important Safety Considerations
Converting a grill is a modification that requires care.
Ventilation Is Key
Always perform conversions and use the converted grill in a well-ventilated outdoor area. This is crucial for preventing carbon monoxide buildup.
Gas Leak Detection
Never skip the leak detection step. Use a commercial gas leak detector or a generous amount of soapy water. Even a small leak can be dangerous.
Professional Help
If you are not comfortable with any part of this process, or if you encounter problems, it is always best to consult a qualified gas appliance technician. They have the expertise and tools to ensure the conversion is done safely and correctly.
Hose Length And Type
Ensure the natural gas hose is the correct length and type specified for natural gas appliances. Propane hoses are designed for higher pressure and may not be suitable.
Local Regulations
In some areas, there might be local building codes or regulations regarding gas appliance modifications. It’s a good idea to check if any permits or inspections are required.
