Can A Blackstone Grill Be Converted To Natural Gas? | The Real Limits

Yes, many larger propane griddles can switch to a home gas line with the brand’s conversion kit, but several Blackstone models cannot.

A lot of Blackstone owners hit the same point: the grill works fine on propane, but hauling tanks, checking fuel levels, and swapping bottles gets old. A natural gas hookup sounds cleaner, cheaper over time, and easier for frequent cooks.

That idea can work. Still, not every Blackstone unit is built for it. Some models take a factory conversion kit with the right natural gas orifices and hose. Others are a flat no. That split is what trips people up.

If you want the straight answer, here it is: a Blackstone grill can often be converted to natural gas only when Blackstone says your exact model is compatible and you use the matching kit. If your griddle is on the no-go list, forcing a conversion is a bad bet. Flame performance can suffer, ignition can get finicky, and you can end up with a unit the brand does not stand behind.

When A Blackstone Grill Can Be Converted To Natural Gas

Blackstone does sell factory conversion kits, which tells you the idea itself is valid. The catch is model fit. The company says its natural gas conversion kit works with selected 28-inch, 30-inch, 36-inch, and Tailgater units, while several tabletop, drop-in, pizza oven, air fryer combo, and Select collection models are not compatible. You can check Blackstone’s natural gas compatibility article and match your model before buying anything.

That model check matters more than the size written on the front shelf. Blackstone has made many griddles that look close at a glance yet use different burner setups, plates, regulators, or fuel paths. Two 36-inch units can sit side by side and still have different conversion status.

The safest way to verify yours is simple:

• Find the model number on the rating label or manual.
• Check whether Blackstone lists that model as natural gas compatible.
• Buy the kit that matches the approved units.
• Use the correct natural gas orifices supplied in the kit.
• Test all connections for leaks after installation.

If any part of that chain breaks, stop there. A gas appliance is not the place for guesswork.

Why The Conversion Is Not Just A Hose Swap

Plenty of people assume propane and natural gas are close enough that the change is all about connectors. It is not. The fuel burns at a different pressure and needs different orifices to meter gas flow the right way.

Leave the propane orifices in place and hook the grill to natural gas, and the burners may run weak. Swap parts that do not match the unit, and the flame can act odd or uneven. On a griddle, that shows up fast: one zone lags, preheat drags, and your left side browns while the right side limps along.

Blackstone’s own natural gas conversion kit includes the hose, quick connect fitting, thread gauges, wrench, and multiple orifices for approved griddles. That tells you the process calls for more than one part and more than one step.

Models That Often Work And Models That Usually Do Not

You will get the clearest answer by checking the model list from Blackstone, not by relying on forum chatter. Still, the broad pattern is easy to read. Larger freestanding griddles are the common candidates. Portable, compact, and combo units are where the no answers pile up.

Blackstone Type	Natural Gas Status	What To Watch
28-inch griddles	Many approved models can convert	Check the exact model number before buying a kit
30-inch griddles	Some approved models can convert	Do not assume all 30-inch units share the same parts
36-inch griddles	Many approved models can convert	Older and newer versions may differ
Tailgater units	Some approved models can convert	Verify burner layout and kit fit
17-inch tabletop griddles	Usually not compatible	Portable units often stay propane only
22-inch tabletop griddles	Usually not compatible	Do not treat size as proof of compatibility
Drop-in griddles	Often need a separate built-in kit or are excluded from the standard kit	Built-in and freestanding kits are not the same
Pizza ovens	Not compatible with the standard conversion kit	Fuel parts and burner design differ
Air fryer combo units	Often not compatible	Blackstone flags many propane combo units as non-convertible
Select collection models	Not compatible in Blackstone’s help article	Do not buy a kit based on shelf size alone

This is why “Can A Blackstone Grill Be Converted To Natural Gas?” has no one-size-fits-all answer. The brand itself splits the lineup into yes, no, and model-check-first buckets.

What Happens After A Proper Conversion

A correctly converted unit can be pleasant to live with. You lose the propane tank shuffle. Fuel supply feels steady. Long weekend cooks get easier since you are not guessing how much gas is left in the bottle.

There is also a routine comfort factor. You roll the griddle out, connect it, preheat, and cook. No spare tank in the garage. No last-minute refill run when you planned burgers for eight people.

That said, natural gas is not always the stronger performer on raw heat. Some owners notice a softer top-end burn compared with propane. For most backyard cooking, that is not a deal breaker. Smash burgers, fried rice, eggs, onions, bacon, and quesadillas still fit the wheelhouse. You may just need a touch more preheat time or a bit more patience in cold weather.

Before You Convert, Check These Practical Points

Even when your Blackstone is approved, the switch still needs a little planning. The griddle is only one piece of the setup. Your house gas line, shutoff location, quick-connect fitting, and pressure all matter too.

• Gas supply: Your outdoor line must deliver the pressure and flow the grill expects.
• Placement: The hose length needs to suit where the griddle sits during cooking.
• Mobility: A natural gas griddle is less grab-and-go than a propane setup.
• Manual match: Use the manual for your exact unit, not a close cousin from the same shelf size. Blackstone’s product manuals page makes that easier.

If your patio layout changes often, propane may still suit you better. If the griddle lives in one spot and gets used every week, natural gas starts to make a lot more sense.

Propane Vs Natural Gas On A Blackstone

The fuel choice is not just about “Can it be done?” It is also about whether the switch fits the way you cook. Here is the trade-off in plain language.

Factor	Propane	Natural Gas
Fuel source	Portable tank	Fixed home gas line
Mobility	Easy to move anywhere	Best for one regular cooking spot
Refueling	Tank swaps or refills	No tank changes during normal use
Setup work	Simple out of the box	Needs approved conversion parts and install steps
Heat feel	Often stronger at the top end	Can feel a bit softer on some griddles
Long cook sessions	Limited by tank level	Steady fuel supply from the house line

There is no universal winner. A tailgater or renter may stick with propane and be happy. A homeowner who cooks breakfast outside every Saturday may love natural gas and never want to go back.

Signs You Should Not Convert

Sometimes the best move is to leave the grill exactly as it is. Skip the conversion if any of these apply:

• Your model is listed as incompatible.
• You cannot confirm the model number.
• You plan to move the griddle around often.
• Your patio has no practical gas line access.
• You are thinking about third-party parts that Blackstone does not approve.

That last one is where many headaches start. Off-brand conversion parts can sound tempting when a hose looks “close enough.” Gas equipment is not forgiving like that. Saving a few bucks up front can turn into poor flame control, leaks, or a griddle that cooks worse than it did on day one.

What Most Buyers Get Wrong

The most common mistake is shopping by size alone. Someone sees “36-inch Blackstone” and buys a natural gas kit before checking the label. Then the kit shows up, the parts do not line up cleanly, and the whole thing turns into a half-day mess.

The second mistake is treating internet comments like factory documentation. One owner may have converted an older model and had zero trouble. That does not prove your newer unit shares the same burner setup. Blackstone has changed models, collections, and plate designs over time.

The third mistake is expecting the converted griddle to feel identical to propane in every condition. A proper conversion should cook well. It still may not behave exactly the same at full blast, especially in wind or cold air.

Should You Convert Or Buy A Natural Gas Model?

If your current griddle is approved and already fits your cooking style, conversion is often the cheaper move. You keep the cart, shelves, cover, and cooking surface you already know. You just change the fuel source the right way.

If your model is not approved, or if you were already shopping for a new unit, buying a factory natural gas model can be the cleaner play. That cuts out compatibility worries and lets you start with the fuel setup you wanted from day one.

For most people, the answer comes down to one clean test: does Blackstone approve your exact model for natural gas? If yes, conversion can be a smart patio upgrade. If no, leave the hacks aside and either stay with propane or buy a natural gas-ready unit.
