How Do You Convert a Natural Gas Stove to Propane: Easy Guide

exact make and model. A typical conversion kit includes:

• Propane orifices: Small brass fittings with a smaller hole for propane.
• Regulator spring or replacement regulator: Some stoves need a different regulator, or you may need to adjust the existing one.
• Air shutter adjustment instructions: These help you set the right air-to-gas mix.
• Detailed instructions: These are specific to your stove model and should be followed exactly.

Never use a “universal” kit unless the manufacturer says it’s safe for your stove. The wrong orifice or regulator can create major safety risks.

Common Tools

Here are the basic tools you’ll need:

• Wrench set (usually adjustable and open-end wrenches)
• Screwdrivers (flathead and Phillips)
• Pipe thread sealant or yellow Teflon tape (for gas connections)
• Small brush and soapy water (for leak testing)
• Flashlight (for seeing inside the appliance)
• Needle-nose pliers or socket set (for hard-to-reach parts)

Some stoves also require a manometer to check gas pressure. This is more advanced, but it’s important for correct adjustment.

Safety Gear

Don’t forget personal protection:

• Gloves (to protect your hands from sharp edges and chemicals)
• Safety glasses (gas lines can have debris)
• Fire extinguisher nearby (as a precaution)

It’s easy to overlook safety gear, but it’s important even for small jobs.

Step-by-step Conversion Process

Converting your natural gas stove to propane takes patience and attention. Here’s a clear walk-through of each step:

1. Read The Owner’s Manual

Before you touch anything, study the manual. Find the conversion section and read it fully. Many manuals also have diagrams, which are useful for finding orifices and regulators.

If you don’t have the manual, check the manufacturer’s website or call their support line. Skipping this step is the biggest mistake DIYers make.

2. Turn Off The Gas And Unplug The Stove

Shut off the gas supply at the main valve. Make sure all stove burners are off. Unplug the stove from the wall to avoid electrical shocks. If you smell gas at any point, stop and ventilate the area.

3. Remove Stove Grates And Burners

Lift off the grates and burner caps. Most stoves let you unscrew or gently lift the burner heads. Keep all parts organized so you can reassemble them later.

4. Replace The Orifices

Each burner has a gas orifice. Use the correct wrench to remove the old (natural gas) orifice and install the new (propane) orifice from your kit. Orifices are often color-coded or marked with numbers—double-check that each one matches the burner size.

Beginner tip: Orifices look almost identical but have different hole sizes. Mixing them up can lead to uneven flames or safety risks.

5. Adjust The Air Shutters

Most burners have a small, adjustable shutter near the orifice. The manual will show how to set these for propane. Use a screwdriver to open or close the shutter until it matches the manufacturer’s setting. This step affects how blue or yellow the flame is.

Non-obvious insight: Too little air means a yellow, sooty flame; too much air gives a noisy, weak flame. The right mix is a steady blue flame with a small yellow tip.

6. Adjust Or Replace The Regulator

Many stoves have a convertible regulator under the back panel or behind the bottom drawer. You may need to remove a cap and flip a plastic disk, or install a new spring from your kit. Follow the manufacturer’s instructions exactly.

Don’t guess: The wrong regulator setting can cause poor performance or dangerous leaks.

7. Reassemble The Stove

Put all burners, caps, and grates back in place. Double-check that everything fits tightly and is aligned as before.

8. Connect To Propane Supply

Attach the propane hose and regulator to your stove. Use only parts approved for propane. Apply pipe thread sealant or yellow Teflon tape to threaded connections, but never on flare fittings.

9. Test For Leaks

Mix a little dish soap with water and brush it onto every gas connection. Turn on the propane supply. If you see bubbles, there’s a leak—tighten the fitting and check again. Never use a flame to check for leaks.

Extra safety: Let the area air out before lighting anything, just in case.

10. Test Burner Flames

Light each burner. The flame should be mostly blue with a small yellow tip. If flames are too high, low, or yellow, adjust the air shutter or call a technician.

Advanced tip: If you have a manometer, check that the pressure matches your stove’s requirements (usually 10-11 inches WC for propane). Too much or too little pressure means the regulator needs adjustment.

11. Final Checks

Make sure all connections are tight and all flames look healthy. Clean up tools and leftover parts. Keep the conversion instructions with your stove in case you move or sell it.

Safety Checks And Common Mistakes

Switching from natural gas to propane isn’t just about following steps—it’s about staying safe. Here’s how to avoid problems:

Key Safety Checks

• Leak Test: Always check every connection with soapy water. Never skip this, even if everything feels tight.
• Proper Orifices: Double-check that each orifice matches the burner size and gas type. Wrong orifices can lead to dangerous flames.
• Air Shutter Setting: Fine-tune the shutters until you see a blue, steady flame. A yellow flame means incomplete burning and can lead to carbon monoxide.
• Ventilation: Make sure your kitchen has good airflow. Propane burns cleaner than natural gas, but poor ventilation is still a risk.
• Regulator Setting: Confirm the regulator is set for propane. This is often missed, leading to poor burner function or leaks.

Common Mistakes

• Skipping the Manual: Every stove is different. Not reading the manual is the top cause of conversion errors.
• Mixing Orifices: Orifices look similar, but even a small difference can be a big safety issue.
• Wrong Tools: Using the wrong wrench can strip orifices, making them impossible to remove or tighten safely.
• Overtightening: Gas fittings need to be snug, not forced. Overtightening can crack parts and cause leaks.
• Ignoring Local Codes: In some places, only licensed technicians can do conversions. Check your local laws before starting.

Extra insight: Many insurance companies won’t cover damage from DIY conversions if something goes wrong. Always keep documentation of the work.

Legal And Insurance Considerations

Before you start, it’s smart to check the legal side of converting your stove. Here’s what you need to know:

Local Building Codes

Building codes vary by state, county, and even city. Some require:

• A permit for any fuel conversion.
• Inspection by a certified technician.
• Only approved parts and kits.

You can usually find your local codes on your city or county website, or by calling the building department.

Manufacturer Warranties

Some manufacturers void your warranty if a non-professional does the conversion. Others require you to use their branded kits. If you skip this step, you may lose warranty coverage for repairs or replacement.

Insurance Impacts

Home insurance often requires proof of “code-compliant” installations. If you do a DIY conversion and there’s a fire or leak, your claim could be denied. Some insurers demand an inspection certificate or a licensed installer’s sign-off.

When To Call A Pro

If you’re unsure about any part of the process, or if your stove is new or expensive, it’s safer to call a qualified technician. Many gas companies offer this service. The cost is usually small compared to the risks of a DIY mistake.

Non-obvious insight: Some states, like Massachusetts and California, have especially strict rules. Always check before you start.

Should You Diy Or Hire A Professional?

Converting a stove is possible for a skilled DIYer, but it’s not for everyone. Here’s how to decide:

Diy Conversion

• You should be comfortable working with gas appliances.
• You must have the right tools and follow the manual exactly.
• You are responsible for any damage or safety risks.
• You need to follow local laws and get inspections if needed.

Professional Conversion

• Pros have the experience to spot hidden problems (like corroded lines or incorrect pressures).
• They can certify the work for insurance and resale purposes.
• They know local codes and can pull permits if needed.

Cost comparison: A professional conversion usually costs between $100–$300, depending on your location and stove model. DIY can be cheaper, but only if you already have the tools and are confident in your skills.

Real-world Example

Imagine you have a 5-year-old stove in a new rural home. You check the manual and see it’s convertible. You buy the kit for $60 and spend another $30 on tools and sealant. The job takes about 2 hours and goes smoothly.

You test for leaks, adjust the flames, and save money.

Now, imagine you skip a step and a leak causes a small fire. Your insurance denies the claim because there’s no professional sign-off. The cost of repairs is much higher than hiring a tech in the first place.

Troubleshooting After Conversion

Sometimes, even when you follow every step, things don’t work perfectly. Here are solutions to common problems:

Flames Are Too Large Or Small

• Check orifice size: You might have mixed up the orifices.
• Check regulator setting: Make sure it’s set for propane, not natural gas.
• Check gas pressure: If you have a manometer, measure it at the stove.

Flames Are Yellow And Sooty

• Adjust air shutters: Open them slightly until the flame turns blue.
• Check for obstructions: Sometimes debris blocks the burner holes.

Burners Don’t Light

• Check connections: Make sure all hoses and fittings are tight.
• Check spark igniters: If electric, make sure the stove is plugged in.
• Check propane tank: Make sure it’s full and the valve is open.

Smell Of Gas

• Turn off supply immediately: Ventilate the area and check all fittings with soapy water.
• Call a professional: If you can’t find the leak, don’t use the stove.

Uneven Flame

• Clean burners: Residue from old gas can block holes.
• Re-seat burner caps: Make sure they are centered and level.

Maintenance Tips After Conversion

Keeping your propane stove working well is as important as the conversion itself. Here’s how to maintain your stove:

• Regularly check for leaks: Every few months, use soapy water on connections, especially after moving the stove or changing tanks.
• Clean burners: Remove caps and wipe out debris. Blocked holes cause uneven flames.
• Inspect propane hose: Replace hoses if you see cracks, kinks, or wear.
• Check flame quality: If you see yellow flames or soot, adjust air shutters or call a technician.
• Service regulator: Some regulators need periodic replacement (every 5–10 years), especially in outdoor kitchens or RVs.
• Store propane tanks safely: Always keep them upright, outdoors, and away from heat sources.

Pro tip: Keep your conversion manual and kit parts in a safe place. If you move or resell the stove, you’ll need them.
