Best Tubular Gas Burner For Pizza Oven: 5 Models Compared and Reviewed

If you own a pizza oven that runs on wood or pellets, or you’re shopping for one, a tubular gas burner can change how you cook. Instead of tending a fire for 20 to 30 minutes, you turn a knob and get a steady flame. That consistency matters most when you’re cooking several pizzas in a row, because the oven floor and dome stay at a more predictable temperature. The catch is fit. These burners are built for specific oven models, so the right choice depends on what you already own. This guide reviews five tubular gas burners sold for 12-inch pizza ovens, explains what each one does well, and shows you what to check before you buy.

BIG HORN OUTDOORS Propane Burner: A Full Gas Conversion for 12-Inch Ovens

This burner is designed for the BIG HORN OUTDOORS 12-inch pizza oven. It mounts on the rear of the oven, so the flame feeds in from the back and heats the cooking chamber without any wood or pellet fuel. The listing describes a heat control dial with a range up to 350°C, along with a low-power setting meant for slower cooking. That low-power option is useful if you want to cook meat or bake at a gentler temperature rather than running the oven at full blast.

The build centers on practical parts. The package includes a heavy-duty gas hose and a pressure regulator, so you don’t need to shop for those separately. That matters because a mismatched regulator is one of the most common setup problems with gas accessories. The burner is meant to work with propane or natural gas, which gives you flexibility, but you should confirm the fuel source with the seller and your own tank setup before you connect anything.

In everyday use, many owners appreciate that the burner turns a 12-inch oven into a low-maintenance tool. You skip the wood splitting, the ash cleanup, and the long wait for the fire to settle. Buyers often note that the setup is straightforward, which makes this a good option for someone who wants a plug-and-go conversion. The trade-off is that you are committing to a burner built around one specific oven line. If you plan to move to a different brand later, this burner will not follow you.

Compared with the Ooni and CSZKJXPA options in this list, this product stands out because it bundles the regulator and hose with a burner matched to its own oven. That reduces guesswork. Its biggest limitation is that the listing does not spell out as many install details as some competitors, so read the included instructions carefully before your first burn.

Pros:

• Includes a heavy-duty gas hose and pressure regulator, so the core setup parts are covered
• Designed to mount directly on the back of a matching 12-inch BIG HORN oven
• Low-power cooking function gives you more control for slower dishes
• Cuts down on soot and cleanup compared with a wood fire

Cons:

• Limited to one specific oven line, so it is a poor fit for other brands
• Fuel compatibility should be verified before connecting to your tank

Verdict: If you own a BIG HORN OUTDOORS 12-inch oven and want a complete gas kit with the regulator and hose already included, this is one of the simplest ways to make the switch. Confirm your oven model first, and you can buy with confidence.

Ooni Karu 12 and Karu 2 Gas Burner: A Brand-Matched Option for Ooni Owners

This Ooni burner is made for the Karu 2 and Karu 12G pizza ovens. It attaches to the back of the oven and converts it to propane, which gives you a quick, low-maintenance alternative to wood. The listing states that it can reach up to 950°F, which places it in the same high-heat range as the other burners in this group. A low-power cooking function is also included, so you can use the same burner for slower cooking when you’re not making pizzas.

The kit includes a 28 mbar propane regulator and hose. That pairing matters, because the regulator is the part that controls how much gas reaches the burner. The listing ties the burner to Ooni’s own oven models, which keeps the fit question simple if you own one of them. It is worth noting that the listing names both the Karu 2 and the Karu 2/12G, so double-check your exact model number before ordering.

Owners often describe the Ooni attachment as easy to live with. It doesn’t demand a lot of fuss, and the flame control is responsive enough for turning out pizzas one after another. Some users report that the soot buildup is noticeably lower than with wood, which keeps the oven cleaner between cooks. The tradeoff is cost of ownership in a practical sense. You will need propane refills, and if you run the oven hot for long sessions, you will go through a tank faster than you might expect.

Against the BIG HORN burner, this Ooni option is the better pick if you already own a compatible Ooni oven. Against the third-party kits, it trades some flexibility for a more predictable match between parts and oven.

Pros:

• Built for Ooni Karu 2 and 12G ovens, which reduces fit concerns for owners of those models
• Includes a 28 mbar propane regulator and hose in the package
• Low-power function adds flexibility beyond high-heat pizza baking
• Produces less soot than wood-fired cooking

Cons:

• Compatibility is narrower than some alternatives, and the model wording should be checked closely
• Propane use adds ongoing fuel cost, especially during long cooking sessions

Verdict: For owners of a compatible Ooni Karu 2 or 12G oven who want a brand-matched gas burner with its own regulator and hose, this is a strong and dependable choice. If your oven is not on the compatibility list, skip it.

YFLWGFDA Gas Burner Attachment: A Propane Upgrade for Wood-Fired 12-Inch Ovens

This attachment is sold as a way to switch a 12-inch outdoor pizza oven from wood to propane. The listing says it is designed to fit most 12-inch outdoor ovens, including the Karu 12 and Karu 12G. Because “most” is not the same as “all,” you should check your oven’s dimensions and model before you buy. The listing itself makes the same recommendation.

The package includes a 5-foot propane hose with a regulator. A 5-foot hose gives you room to place the propane tank a comfortable distance from the oven, which is a sensible safety habit. The instructions call for a leak test before lighting, and they describe a lighting sequence that involves opening the tank slowly, pressing and turning the knob until you hear a click, and holding it briefly before turning it to the on position. Following that sequence carefully helps prevent the common mistake of trying to light a burner that hasn’t fully primed.

The listing says the flame can reach up to 950°F in 20 to 25 minutes. It also describes a flame pattern meant to spread heat across the oven roof, which helps heat the stone evenly. Many owners appreciate the simple knob control, since it removes the constant need to feed and adjust a wood fire. That makes it easier to focus on dough, toppings, and timing.

Among the Karu-compatible options here, this one is the most practical for someone who wants a propane conversion without a lot of extra parts. It does not include the extra install tools that the CSZKJXPA kit provides, so plan for a few minutes of setup work.

Pros:

• Includes a 5-foot propane hose with regulator, which allows safer tank placement
• Knob-based temperature control removes the need to manage a wood fire
• Listing describes heating up to 950°F within about 20 to 25 minutes
• Clear lighting and leak-test instructions make first use less intimidating

Cons:

• The “fits most 12-inch ovens” wording means you must verify your exact model

Verdict: If you own a wood-fired 12-inch oven, such as a Karu 12 or 12G, and want a straightforward propane upgrade with a safe hose length, this is a sound choice. Confirm the fit before ordering, and you will likely be happy with the results.

CSZKJXPA Gas Burner Kit: A Complete Install Package for Karu and Fyra Ovens

This kit is listed for the Karu 12, Karu 12G, and Fyra 12 pizza ovens. Of all the options here, it offers the most complete package. The listing says the box includes the burner, a propane regulator with hose, a match holder, screws, a wrench, and thread sealant tape. For a first-time installer, having the tools and sealing supplies in the box removes several trips to the hardware store.

The listing describes a larger top flame coverage, which is intended to spread heat more evenly across the oven. Even heat matters for pizza because uneven flame can scorch one side of the crust while the other side stays pale. The listing also says the oven reaches 950°F in about 20 minutes, which is a useful benchmark when planning your cook time. It also points out that the chimney vent should be open for steady flames, a detail that is easy to forget.

Buyers often appreciate the included thread sealant and wrench, because a loose or poorly sealed fitting is the most common source of gas leaks. Still, the kit asks more of you during setup than a simple attachment. You need to be comfortable with threaded connections and with running a leak test before each first use of the season. The listing also suggests keeping the hose clear of the oven, which is a practical reminder for any propane setup.

Compared with the YFLWGFDA attachment, this kit is more complete and slightly more involved to install. It is a good match for someone who wants everything in one box and doesn’t mind a bit of hands-on assembly.

Pros:

• Includes install tools and sealing supplies, including a wrench, screws, and thread sealant tape
• Compatible with Karu 12, Karu 12G, and Fyra 12 models as listed
• Listing describes a wider top flame pattern for more even heat
• Clear step-by-step lighting guidance, including the importance of an open chimney vent

Cons:

• Installation requires more hands-on work and comfort with threaded gas fittings

Verdict: If you want an all-in-one kit for a Karu 12, Karu 12G, or Fyra 12 and are comfortable with a short installation, this is the most complete option in this list. Double-check your oven model before ordering to ensure a proper fit.

Ooni Karu 12 Gas Burner: An Improved Low-Power Attachment With Limited Availability

This Ooni burner is made for the Karu 12 and attaches to the back of the oven to add gas power. The listing describes it as an improved version with a low-power cooking function, a faster recharge time, and a fully serviceable body. The serviceable body is a practical detail. It suggests that parts can be maintained or replaced rather than forcing you to discard the whole burner when something wears out.

The package includes a 28 mbar regulator and gas hose. The listing also sets a clear usage rule: the burner can only be used with the oven door removed and the chimney in place. That is an important operating condition, and it affects how you set up your outdoor space. You will need to plan for the door to be off during gas cooking, which changes how heat is held inside the oven.

Owners who value controlled, lower-temperature cooking may like the low-power function. It makes the burner useful for more than pizza, including slow-cooked meats and other dishes that benefit from gentler heat. The faster recharge time also suggests that the burner can get back to working temperature more quickly between batches, which helps when you are cooking for a crowd.

The main drawback is availability. The listing currently shows as unavailable, so check stock before you plan a purchase around it. If it returns to stock, it is a capable Karu 12 option, but the door-off requirement is a real limitation for anyone who prefers to keep the door in place.

Pros:

• Low-power cooking function supports slower dishes as well as pizza
• Serviceable body design makes long-term maintenance more practical
• Includes a 28 mbar regulator and gas hose
• Improved recharge time is useful for back-to-back cooking

Cons:

• Must be used with the oven door off, which changes how the oven holds heat
• The listing is currently unavailable, so stock is uncertain

Verdict: If you own a Karu 12, want a serviceable burner with low-power control, and are comfortable running the oven with the door off, this is a good choice when it’s in stock. If you need to keep the door on or the item is unavailable, look at one of the other options above.

How to Choose the Right Tubular Gas Burner for Your Pizza Oven

Confirm Your Oven Model and Fit

Fit is the first thing to check, and it is the factor that causes the most wasted money. Each burner in this list is tied to a specific group of ovens. Some are built for a particular brand, such as Ooni or BIG HORN OUTDOORS, while others are sold for several 12-inch models. Before you buy, look up your oven’s exact model name and size. Then compare that information to the compatibility wording in the listing. If a listing says “fits most” ovens, treat that as a reason to measure and verify rather than a guarantee.

Understand Regulator Pressure and Fuel Type

The regulator controls how gas flows from your tank to the burner, so it has to match the burner’s design. Several of the listings here mention a 28 mbar regulator. That is a pressure rating used in many propane setups. Your tank and regulator setup should work with the burner you choose, so check the fuel type stated in the listing and confirm your tank connection before you light anything. If a listing mentions both propane and natural gas, verify exactly which fuel the included parts support, since the connection hardware is different for each.

Check What Comes in the Box

Some kits include only the burner, while others bundle a regulator, hose, and install tools. A bundled regulator and hose save you from guessing at parts, which is helpful for first-time buyers. A kit with screws, a wrench, and thread sealant tape can also shorten setup time. If you already own a regulator and hose from another appliance, make sure they are compatible before you assume you can reuse them.

Think About Heat Control and Low-Power Cooking

High heat is the main reason people switch to gas, but control matters just as much. A simple knob that adjusts the flame lets you hold steady temperatures while you bake, and a low-power setting can help with slower cooking. If you plan to roast vegetables, cook meat, or bake bread in addition to pizza, look for a burner that mentions lower-temperature operation. Consistent heat is what keeps crusts from burning before toppings are set.

Evaluate Flame Pattern and Heating Speed

The flame pattern determines how evenly heat reaches the oven stone and dome. A wider or more even pattern helps prevent cold spots and scorched areas. Listings in this group describe heating times of about 20 to 25 minutes to reach high temperatures, along with flame designs intended to spread heat across the roof. Heating speed matters if you plan to host, because a burner that reaches temperature quickly lets you start cooking sooner.

Prioritize Safety and Leak Testing

Any gas appliance requires careful handling. Keep the hose away from the oven, open the tank slowly, and perform a leak test with soapy water before the first use of each season or whenever you reconnect a fitting. Several listings recommend keeping the chimney vent open for steady flames, and one specifies that the oven door should be off during use. Follow the manufacturer’s instructions exactly. A safe setup also means placing the tank on a stable surface outdoors and away from flammable materials.

Consider Build Quality and Serviceability

A burner that will live outdoors needs durable materials and solid fittings. Look for descriptions of heavy-duty hoses, robust regulators, and parts that can be serviced or replaced. A serviceable design can extend the life of the burner and save money over time. Also consider how the burner attaches to the oven. A secure, well-fitted mount reduces wobble and helps keep the flame stable.

Plan for Availability and Support

Stock levels change, and a product that is unavailable today may return later. Check availability before you commit to a model. It also helps to find out how the seller handles questions or problems. Several listings in this group mention customer support channels, so look for sellers who respond clearly to setup questions. Good support can be just as valuable as a good product when you are working with gas.

Frequently Asked Questions

Do I need a special tank to run a tubular gas burner?

Most of these burners are sold for propane, and the listings include a regulator and hose designed for that fuel. You still need a compatible propane tank and a regulator that fits the burner’s connection. Confirm the fuel type and regulator rating in the listing before you connect the tank.

Can I use one of these burners with any 12-inch pizza oven?

No. Each burner is tied to specific oven models or brands. Some listings say they fit most 12-inch ovens, but that is not a guarantee. Measure your oven and check the model name against the listing before you buy.

Why does the Ooni Karu 12 burner require the oven door to be off?

The listing states that the burner can only be used with the oven door off and the chimney on. That condition is set by the manufacturer. Running the oven with the door off changes how heat is retained, so follow the instructions and plan your cooking area accordingly.

How long does it take to heat the oven with a gas burner?

Several listings in this group describe reaching high temperatures in about 20 to 25 minutes. Actual heating time depends on your oven, weather, tank pressure, and burner setting, so use the listing as a general guide and check the oven’s temperature before cooking.

Do I need to perform a leak test before lighting the burner?

Yes. A leak test is a standard safety step for any propane connection. Apply soapy water to the fittings and watch for bubbles while the tank is open. If you see bubbles, close the tank, tighten the connection, and test again. Never light a burner with a suspected leak.

Will a gas burner produce less soot than a wood fire?

Generally, yes. Several listings and many owners note that gas cooking leaves less soot and ash than wood or pellet fires, which makes cleanup easier. Gas still produces some residue over time, so regular cleaning of the oven interior is still a good habit.

Which burner is best for a first-time gas conversion?

For a first-time buyer with a compatible oven, the CSZKJXPA kit is a strong choice because it includes install tools and sealing supplies. If you own a BIG HORN OUTDOORS oven, the BIG HORN burner is the simplest match. Both reduce the guesswork that often trips up new installers.

Final Recommendation

The best tubular gas burner for your pizza oven depends mostly on which oven you own. If you have a BIG HORN OUTDOORS 12-inch oven, the BIG HORN burner is the most direct path, since it includes the hose and regulator and is designed for that oven. If you own a compatible Ooni Karu 2 or 12G, the Ooni Karu 12 and Karu 2 burner offers a brand-matched solution with a 28 mbar regulator and hose. For wood-fired Karu 12 or 12G owners who want a practical propane upgrade, the YFLWGFDA attachment is an efficient pick with a safe-length hose and simple knob control.

If you want the most complete package and don’t mind a short installation, the CSZKJXPA kit covers Karu 12, Karu 12G, and Fyra 12 ovens with the tools and sealant you need. The Ooni Karu 12 burner is a capable option with low-power cooking, but its door-off requirement and current unavailability make it a more specialized choice. Whichever you choose, confirm your oven model, check the regulator and fuel type, and perform a leak test before your first cook.
