Yes, some propane grills can be converted to natural gas, but only with a maker-approved kit for your exact model.
If you’re asking can i convert propane grill to natural gas, the real answer is not “grab a kit and swap a hose.” It comes down to your grill model, the parts inside the gas train, and what the maker allows. Some grills are built for dual-fuel use. Many are not. That split matters because a bad conversion can lead to weak heat, flare issues, gas leaks, or a voided warranty.
The good news is that this is usually a clean yes-or-no call once you know where to look. You do not need to guess. Check the rating label, the owner’s manual, and the parts list for a natural gas conversion kit tied to your exact model number. If your brand says no conversion, take that answer at face value.
This guide walks you through the safe path, the parts that change, the red flags that stop the job, and when buying a natural gas grill makes more sense than converting the one you already own.
Can I Convert Propane Grill To Natural Gas? The Real Rule
Some propane grills can be converted. Some flatly cannot. The safe rule is simple: only convert a grill if the maker sells or approves a conversion kit for that exact grill model. Not the same series. Not a close match. The exact model.
That rule exists for a reason. Propane and natural gas do not burn the same way. Propane carries more heat per unit than natural gas, and grills built for one fuel are tuned around that fuel’s pressure and flow. A proper conversion changes the regulator setup and the gas metering parts so the burners get the right mix. A random aftermarket kit may not do that well.
Major brands handle this in different ways. Weber states that it does not allow grill conversions or provide conversion kits, citing safety and warranty concerns. Char-Broil sells a natural gas conversion kit for certain Dual Fuel models from 2020 or newer. Napoleon also sells conversion kits for some built-in models. That tells you the big lesson: the brand and model decide the answer, not a universal “grill hack.” :contentReference[oaicite:0]{index=0}
If your manual says “convertible” or lists a fuel conversion kit by part number, you may have a green light. If the manual says the grill is for propane only, stop there. Do not drill orifices. Do not swap random regulators. Do not let a cheap kit make the call for you.
How Propane And Natural Gas Grills Differ
At a glance, the grills look the same. Inside, they are set up around fuel pressure and gas volume. Propane burns hotter per unit than natural gas, so natural gas grills need more flow to hit similar cooking heat. That usually means different burner orifices, a different regulator setup, or valves designed for conversion.
Natural gas delivered to consumers is usually a little over 1,000 Btu per cubic foot, while propane has much higher heat content by volume. That energy gap is one reason a propane setup cannot simply be fed by a home gas line and expected to work right. :contentReference[oaicite:1]{index=1}
| Item | Propane Grill | Natural Gas Grill |
|---|---|---|
| Fuel source | Portable tank | Home gas line |
| Heat content | Higher per unit | Lower per unit |
| Typical setup need | Smaller fuel flow parts | Larger flow parts |
| Mobility | Easy to move | Fixed in place |
That difference also affects day-to-day use. A natural gas grill is handy if you cook at home often and do not want to refill tanks. A propane grill is easier if you move the grill around the yard, take it on trips, or rent a place without a gas stub on the patio.
So the conversion question is not only “Can it be done?” It is also “Will the finished setup fit how I cook?” If you need portability, a natural gas conversion can solve one headache and create another.
How To Check If Your Propane Grill Can Be Converted
Start with the grill itself, not online chatter. Your best clues are the rating plate, the owner’s manual, and the replacement parts list. Most grills hide the model label on the back panel, inside a cabinet door, or under the firebox.
- Find The Model Number — Use the full model number, not just the series name on the lid.
- Read The Manual — Search for “natural gas,” “conversion kit,” or “dual fuel.”
- Check The Parts Page — Look for a kit tied to your exact model year and trim.
- Read The Warranty Notes — Some brands say any conversion voids coverage.
- Check Your Fuel Stub — Make sure you have a proper outdoor natural gas connection where the grill will sit.
If you find mixed signals, trust the newest official source from the maker. A sales listing, manual revision, or parts page tied to your model year is more useful than an old forum post.
A few cases need extra care. Brands sometimes change valve designs mid-generation. A 2019 version of a grill may not take the same kit as the 2021 version with a near-identical name. Built-in grills also play by their own rules because the enclosure, hose routing, and shutoff setup can differ from freestanding carts.
That is why “close enough” is a trap here. A conversion kit is not a generic accessory like a grill cover. It is part of the fuel system. Treat it that way.
Parts In A Natural Gas Conversion And Why They Matter
A proper propane-to-natural-gas conversion usually involves more than a hose. The exact mix depends on the grill design, though the usual pieces are the natural gas hose, quick-connect fitting, regulator or regulator-related parts, burner orifices, and maker-specific valve components.
Burner Orifices
These small fittings meter gas into each burner. Since natural gas needs more volume than propane for similar heat, the orifice size is not the same. Using the wrong orifice can leave you with weak flames, yellow tips, soot, delayed ignition, or runaway heat.
Regulator And Pressure Parts
Propane from a tank and natural gas from a home line arrive under different conditions. The regulator and pressure setup must match the fuel. A conversion kit built by the maker is designed to keep burner pressure in the range the grill was tested for.
Valves And Fuel Train Pieces
Some grills have convertible valves. Some do not. This is one reason certain brands allow conversions on selected models while others do not allow them at all. The valve design can be the deal-breaker.
The product standards around outdoor cooking gas appliances and conversion kits exist because these parts are not cosmetic. They are tied to fire safety and combustion behavior. CPSC notes work with CSA and NFPA on safety standards for LP gas appliances such as grills, and current CSA standards include provisions for outdoor cooking appliance conversion kits. :contentReference[oaicite:2]{index=2}
If a seller offers a “fits most grills” conversion kit, be skeptical. “Most” is not enough when you are dealing with burner pressure, ignition, and fuel flow.
When Converting Makes Sense And When Buying A New Grill Is Smarter
A conversion can be worth it if you already own a solid grill, cook at home often, and have a proper natural gas stub in the right spot. In that case, the project can save you from tank swaps and keep your patio setup cleaner.
It makes less sense when the grill is old, parts are scarce, or the conversion kit costs enough to get close to a new grill built for natural gas from day one. If your burners are tired, your igniter is flaky, and your grates are on their last legs, pouring money into a conversion may not pencil out.
Good Cases For Conversion
- You Grill At Home Often — A fixed gas line is handy when the grill rarely moves.
- Your Model Is Approved — The maker sells a kit for your exact model number.
- Your Grill Is In Good Shape — Burners, valves, and firebox still have plenty of life.
Bad Cases For Conversion
- The Brand Says No — A no from the maker ends the project.
- The Grill Is Worn Out — You may pay for fuel parts on a grill near retirement.
- You Need Portability — Natural gas ties the grill to one spot.
There is also the install side. If you do not already have an outdoor quick-connect line in place, the gas line work may cost more than the kit. That swings the math hard. A low-cost used propane grill plus a new gas line is often a worse deal than buying the right natural gas grill once.
Safe Setup Steps After A Maker-Approved Conversion
If your grill is approved for conversion and you have the proper kit, go slow. Follow the manual line by line. Do not skip the leak test. Do not fire the grill “just to see.” Gas work rewards patience.
- Shut Off The Fuel — Tank valve closed, home gas line valve closed, grill fully cool.
- Install Only The Listed Parts — Use the kit for your exact model, not leftover pieces.
- Route The Hose Cleanly — Keep it away from hot panels, sharp edges, and pinch points.
- Check The Quick-Connect — Confirm the fitting locks fully and does not twist loose.
- Run A Leak Test — Use a soap-and-water mix on all connections before lighting.
- Light One Burner First — Watch for even blue flame, then test the rest.
- Do A Heat Check — Preheat the grill and make sure it reaches normal cooking range.
If the flame is lazy, tall, noisy, or bright yellow after the setup, stop and recheck the parts list. If anything smells off, shut down the gas at once. Yellow flames can point to bad combustion or the wrong setup. That is not something to “burn off.”
For many homeowners, this is a fair point to bring in a licensed gas fitter. The grill kit may be simple, yet the line hookup, shutoff valve, and outdoor fitting still need to be right. NFPA 54 covers fuel gas piping systems and related appliance installation. Local code may add more rules on top. :contentReference[oaicite:3]{index=3}
Common Mistakes That Cause Trouble
The most common mistake is assuming all grills can be converted. They cannot. The second is buying a cheap universal kit based on a photo match. The third is skipping the model-year detail and ordering the wrong kit for a later or earlier version.
Another miss is focusing only on whether the burners light. A grill can light and still be set up wrong. Weak preheat, soot under the lid, odd flare behavior, and hot spots can all point to a poor conversion. The grill is telling you something.
Then there is the warranty angle. Weber says conversions are not allowed and can void the warranty. If your brand takes the same line, a DIY conversion can cost you coverage on valves, burners, or the whole grill body. :contentReference[oaicite:4]{index=4}
One more trap: patio placement. A natural gas grill tends to stay put. That means you need enough hose slack for safe lid use and cleaning, though not so much hose that it drapes near hot metal or foot traffic. Good fuel flow is only part of a safe setup. Good placement matters too.

Frequently Asked Questions
Can I use a universal conversion kit on my propane grill?
That is a bad bet. Fuel parts are tied to burner design, valve setup, and model-year changes. A kit that “fits most” grills may still meter gas wrong on yours.
Stick with a kit listed by the grill maker for your exact model number. If no such kit exists, treat the grill as non-convertible.
Will a converted grill get as hot as it did on propane?
It can, though only when the conversion is designed for that grill. Natural gas carries less heat per unit, so the grill needs the right flow parts to make up the gap.
If preheat drags or searing drops off after conversion, that points to a setup issue, not “how natural gas always works.”
Do I need a plumber or gas fitter for the job?
You may not need one for every kit install, though many homeowners still hire one for the gas line side. The outdoor shutoff valve, quick-connect fitting, and leak test all need to be right.
If you do not already have a proper patio gas outlet, bring in a licensed pro for that work.
Can I switch the grill back to propane later?
Only if the maker allows it and sells the correct parts for both fuel types. Some dual-fuel designs make this possible. Many grills do not.
Do not assume reversibility. Check the manual first, since repeated fuel swaps can raise the odds of wrong-part mix-ups.
What is the fastest way to know if my grill can be converted?
Find the full model number on the grill, then search the maker’s manual and parts page for a natural gas conversion kit tied to that number. That is the fastest clean check.
If the brand says conversions are not allowed, you have your answer in minutes and can skip the guesswork.
Wrapping It Up – Can I Convert Propane Grill To Natural Gas?
So, can i convert propane grill to natural gas? Yes, but only when your grill was built for it and the maker backs the conversion with the right kit and instructions. That is the line between a tidy upgrade and a risky experiment.
If your exact model is approved, the switch can be a nice quality-of-life move for a home patio setup. You get steady fuel, no tank swaps, and one less errand before dinner. If your brand forbids conversions, take the hint and shop for a natural gas grill built for the job.
The smartest move is the boring one: verify the model, verify the kit, verify the gas hookup. Do that, and you can answer can i convert propane grill to natural gas with confidence instead of guesswork.
