Converting your grill can be a practical solution based on fuel availability and personal preference. Both natural gas and propane grills have their advantages, and switching from one to the other can offer benefits like improved efficiency and convenience.

We will explain the key differences between natural gas and propane grills and why you might want to convert your grill. You'll also get a step-by-step guide to make the conversion process easy and safe.

Read on to learn how to convert your natural gas grill to propane. This guide will help you make the transition smoothly, ensuring you can enjoy efficient and convenient grilling in no time. Whether you need better fuel availability or just prefer propane, understanding this process is essential.

Differences Between Natural Gas and Propane

Energy Efficiency

Propane contains more energy per cubic foot compared to natural gas. This means that propane can burn hotter and more efficiently, making it ideal for high-temperature cooking.

With propane, you can achieve faster cooking times and better fuel economy, which is a significant advantage for avid grillers. This higher energy content means you’ll use less fuel to achieve the same results, saving money and time in the long run.

Portability

Propane tanks are portable, making them perfect for camping, tailgating, or any outdoor activity. Unlike natural gas, which is delivered through a fixed pipeline, propane tanks can be easily transported and replaced, providing flexibility and convenience wherever you choose to grill.

This portability means you can take your grill on the go, ensuring you can enjoy a barbecue no matter where you are without worrying about connecting to a gas line.

Pressure and Volume

Propane operates at a higher pressure than natural gas and requires different components to handle this increased pressure. This includes specialised regulators and smaller orifices.

The higher pressure allows propane to deliver more energy, but it also means that safety precautions must be strictly followed to ensure proper and secure operation.

Using the correct components is crucial to managing this pressure and preventing potential hazards, ensuring your grill operates safely and efficiently.

Can All Grills Be Converted?

Compatibility Check

Before converting your grill, it's crucial to consult the owner's manual (1). The manual will provide specific information about whether your grill can be safely converted from natural gas to propane. If you can't find the information you need, contact the manufacturer directly.

They can confirm compatibility and provide you with the appropriate conversion kit, which includes all the necessary components for a safe conversion.

Manufacturer Restrictions

Not all manufacturers permit grill conversions due to safety and liability concerns. Some brands explicitly state that their grills should not be converted. However, many reputable brands offer conversion kits, making the process straightforward.

Brands like Alfresco, Delta Heat, MHP, Sedona by Lynx, and Twin Eagles provide kits designed specifically for their grills, ensuring a safe and efficient conversion. Always check with the manufacturer to avoid potential safety issues and ensure you use the correct parts.

Required Tools and Components

To successfully convert your natural gas grill to propane, you need the right tools and components. Here’s a list of what you’ll need to get started:

Conversion Kit Components

• Smaller propane orifices
• Propane regulator and hose
• Air shutter/mixer change

Necessary Tools

• Adjustable wrench
• Screwdriver
• Drill with small bits
• Pipe dope sealant
• Soapy water for leak testing

Step-by-Step Conversion Process

Step 1: Preparation

Check if your grill can be converted by consulting the owner’s manual or contacting the manufacturer. This will confirm whether your specific model can safely switch from natural gas to propane.

Gather the necessary parts and tools, including a conversion kit specific to your grill model. Ensure all parts and tools are ready before starting. This includes an adjustable wrench, screwdriver, drill with small bits, pipe dope sealant, and soapy water for leak testing.

Being prepared with everything you need will make the process smoother and more efficient.

Step 2: Turning Off the Gas Supply

Turn off the natural gas supply and disconnect the gas line from your grill. This step is crucial for safety, as it prevents any potential gas leaks during the conversion process. Ensuring the gas is completely off will provide a safe environment for working on your grill.

Double-check that the gas is shut off entirely to avoid any accidents.

Step 3: Removing Natural Gas Components

Remove the grill grates, burners, and other components to access the orifices and valves. Carefully detach these parts and store them safely for potential future reversion to natural gas. Keeping these parts organised and in a secure place will help if you ever need to switch back.

This step ensures you can easily return to the original setup if needed.

Step 4: Installing Propane Components

Replace the natural gas orifices with smaller propane orifices from the conversion kit. If necessary, use drill bits to slightly enlarge the natural gas orifice holes. Adjust the air shutters to be about one-third open for propane.

If the regulator is convertible, switch it to propane mode or replace it with the new propane regulator provided in the kit. Carefully reassemble the propane gas grill components, ensuring everything fits securely.

Step 5: Connecting the Propane Tank

Attach the propane regulator and hose to the propane tank. Make sure that all connections are tight and leak-free to prevent any gas escape. This step is crucial for the safe operation of your grill.

Double-checking the tightness of all connections will ensure that your grill operates smoothly and safely with propane.

Step 6: Testing for Leaks

Turn on the propane tank while keeping the grill burner knobs off. Apply a soapy water solution to all connections and joints. Look for bubbles which indicate leaks. If you see any bubbles, tighten the fittings and retest until no leaks are detected.

This thorough leak testing process ensures the safety of your newly converted propane grill. It's essential to repeat this step until you are confident that there are no leaks, guaranteeing a safe grilling experience.

Frequently Asked Questions

Can I Connect My Converted Propane Grill to a Natural Gas Line?

No, you cannot connect your converted propane grill to a natural gas line. The natural gas connection requires different components and operates at a different pressure than propane. Using a natural gas connection with a propane grill can be dangerous and may damage the grill.

Always use the appropriate fuel for your grill type.

Can I Only Use Liquid Propane in My Converted Grill?

Yes, after converting your natural gas grill to propane, you should only use liquid propane. The conversion process specifically modifies the grill to safely and efficiently use propane. Using any other type of fuel can be hazardous and may cause the grill to malfunction.

Always follow the manufacturer's guidelines for fuel usage.

Is A Bulk Propane Tank Necessary for My Converted Grill?

No, a bulk propane tank is not necessary for your converted grill. You can use standard portable propane tanks commonly available at hardware stores. However, if you prefer, a bulk propane tank can be used for longer grilling sessions without frequent refills.

Choose the option that best fits your grilling needs and preferences.

What Should I Do If the Gas Shut Off Valve Is Different for Natural Gas and Propane?

If the gas shut-off valve is different for natural gas and propane, you should consult your grill's manufacturer or a professional technician. They can provide guidance on whether a new valve is needed or if adjustments can be made.

Safety is crucial, so ensure the correct valve is used to prevent leaks and ensure proper grill operation.

Conclusion

Converting your natural gas grill to propane can offer increased efficiency and portability. By following the proper steps and using the right tools and components, you can safely make the transition.

Always consult your grill’s manual and, if necessary, seek professional assistance to ensure a successful conversion. With the right precautions, you’ll enjoy the convenience and performance of a propane-powered grill in no time.
