15 Best Propane Fire Pit Inserts for Custom Outdoor Builds in 2027

When building a custom propane fire pit, the Stanbroil 31-Inch Round Fire Pit Burner Pan stands out as the best overall insert due to its balanced size, durable stainless steel construction, and compatibility with standard 20 lb tanks. For those needing a larger footprint, the GRISUN Upgraded 36 x 12 Inch Rectangular Kit offers superior coverage, while the Hiorucet 12 Inch Fire Pit Burner Ring Kit provides an excellent entry-level option with integrated ignition. The primary tradeoff in this category is between BTU output and fuel efficiency; high-output pans heat larger areas but consume propane rapidly, requiring frequent tank swaps. Readers should continue reading to understand which insert size and burner type align with their specific fire pit table dimensions and heating needs.

Key Takeaways

• Stainless steel pans with H-burners distribute heat more evenly than simple ring burners, reducing cold spots in larger rectangular pits.
• Most drop-in inserts require a minimum clearance of 3-4 inches from the fire pit edge to the burner pan to prevent heat damage to the surrounding table material.
• Integrated spark ignition systems add convenience but introduce a maintenance point; manual ignition setups are more reliable long-term but less user-friendly.
• A glass wind guard is not just aesthetic; it protects the flame pattern from wind, improving heat retention and safety in open backyard layouts.
• Propane inserts rated for over 100,000 BTUs often require a regulator upgrade from the standard 11-inch water column model to maintain stable flame height.

More Details on Our Top Picks

1. Stanbroil 31-Inch Round Fire Pit Burner Pan, Drop-in Fire Pit Insert

   

   Best for High-Heat DIY Builds

   View Latest Price

   The Stanbroil stands out for buyers building a substantial round fire pit who want a burner pan rather than an all-in-one kit. Its 24-inch burner ring is rated up to 296,000 BTU, giving it far more stated output than the compact 19-inch WISLULU insert, though that heat depends on a correctly sized gas supply. The 304 stainless steel pan and compatibility with propane or natural gas also make it more adaptable to a permanent installation. Unlike the GRISUN rectangular kit, it leaves the finishing choices—media, ignition, hose, and controls—to the builder. That flexibility is useful for custom projects, but it adds parts to source and makes installation less beginner-friendly. Choose it for a large, tailored fire feature; skip it if you want a ready-to-connect package.

   Pros:

   • 24-inch burner ring rated for up to 296,000 BTU
   • 304 stainless steel pan offers corrosion resistance
   • Supports both propane and natural gas
   • Open design leaves room to customize fire media and installation

   Cons:

   • Gas hoses and connection kit are sold separately
   • No igniter is included
   • High-output installation may require technical gas-line knowledge

   Best for: DIY builders creating a large round fire pit who can size and install the gas connection and choose their own ignition components.

   Not ideal for: First-time installers seeking a complete kit with ignition and hose included, or buyers who need a compact, low-output insert.

   • Pan dimensions:33.4 x 33.4 x 2 inches
   • Material:304 stainless steel
   • Weight:19 pounds
   • Burner diameter:24 inches
   • Fuel compatibility:Natural gas and propane
   • Gas inlet:1/2-inch male
   Our verdict

   “Choose the Stanbroil for a large, customizable round build if you are prepared to supply the connection hardware and ignition.”

2. GRISUN Upgraded 36 x 12 Inch Rectangular Drop-in Fire Pit Burner Kit

   

   Best Complete Linear Kit

   View Latest Price

   For a rectangular fire table, this GRISUN is the most ready-to-assemble choice in this group: it bundles the linear burner, pan, spark ignition, regulator hose, air mixer, wind guard, and lid. That package reduces the parts hunt required by the Stanbroil 31-inch round pan, which is better suited to experienced builders willing to source components separately. The 36-inch flame layout gives a long, modern focal point, while the tempered-glass guard can help shield it from breezes. The tradeoff is a fixed 36-by-12-inch footprint and LPG-only fuel compatibility, so it cannot serve a natural-gas installation. It also supplies no enclosure or table; you still need a properly built base and a compatible cutout.

   Pros:

   • Includes burner, pan, spark ignition, regulator hose, air mixer, wind guard, and lid
   • Long linear flame suits modern rectangular fire tables
   • Tempered-glass wind guard helps shield the flame
   • Stainless steel construction

   Cons:

   • LPG-only, so it does not fit natural-gas installations
   • Rectangular 36-by-12-inch format limits placement options
   • No enclosure or base is included

   Best for: DIYers building a rectangular propane fire table who want ignition, hose, lid, and wind protection in one insert kit.

   Not ideal for: Buyers with round or square openings, natural-gas lines, or no plan for a separate fire-table base.

   • Dimensions:36 x 12 x 2 inches
   • Weight:16.4 pounds
   • Material:201 stainless steel
   • Fuel type:LPG
   • Included components:Linear burner, pan, spark ignition, regulator hose, air mixer, sealing tape, tempered-glass wind guard, and stainless steel lid
   Our verdict

   “Pick this GRISUN for a rectangular propane project where an accessory-rich kit matters more than fuel or shape flexibility.”

3. Fire Ring Burner for Fire Pits and Fireplaces, 18 Inch Black Metal Burner

   

   Best Bare-Bones Replacement Burner

   View Latest Price

   This 18-inch ring is the simplest, least bundled option here: it supplies a burner for an existing fire pit or fireplace rather than a drop-in pan with controls and accessories. Its compact 18-inch diameter can suit a smaller opening, while compatibility with propane and natural gas offers more fuel flexibility than the LPG-only GRISUN kits. Drilled ports are intended to distribute gas around the ring, but the listing gives no fixed BTU figure; actual output depends on the supply setup. Compared with the WISLULU 19-inch insert, this is a lighter, more minimal component, not a complete propane-ready package. The low part count keeps the build flexible, but buyers must confirm the material option, gas sizing, and required fittings before installation.

   Pros:

   • Compact 18-inch ring can fit smaller custom builds
   • Compatible with natural gas or propane
   • Lightweight at 3.44 pounds
   • Includes an installation guide

   Cons:

   • No pan, ignition, regulator, or connection kit is specified
   • BTU output is not stated and depends on the gas supply setup
   • Material may be stainless steel or black steel, so buyers should confirm the version

   Best for: Experienced DIYers replacing or adding a burner ring inside an existing fire pit or fireplace who already have compatible controls and connections.

   Not ideal for: Beginners seeking a complete drop-in pan, included propane regulator, ignition, or a clearly specified heat output.

   • Diameter:18 inches
   • Material:Stainless steel or black steel
   • Fuel compatibility:Natural gas or propane
   • Weight:3.44 pounds
   • Burner ports:Drilled ports for gas distribution
   • Included documentation:Installation guide
   Our verdict

   “Choose this ring as a replacement component for a prepared build, not as a complete propane fire pit insert.”

   → See it on Amazon →

4. 19in Propane Fire Pit Insert Round Drop in for 20 lb Propane Tank

   

   Best for Beginner Propane Installs

   View Latest Price

   The WISLULU is aimed at buyers who want a small round insert with the key propane components already bundled. Its 19-inch pan, spark igniter, control valve, thermocouple, and regulator hose make it more approachable than the bare Fire Ring Burner, which leaves the surrounding hardware to the installer. The thermocouple is designed to shut off gas if the flame goes out, adding a useful safety feature for a breezy patio. At a stated 5,500 BTU, however, it is a modest-flame option rather than a match for the high-output Stanbroil 31-inch pan. It is also propane-only, and the cutout must be sized to the pan. This suits intimate tables, not buyers seeking broad heat coverage.

   Pros:

   • Includes spark igniter, control valve, thermocouple, and regulator hose
   • Designed to connect to a standard 20-pound propane tank
   • Thermocouple is intended to stop gas flow if the flame goes out
   • 304 stainless steel pan

   Cons:

   • Stated 5,500 BTU output is far below the Stanbroil’s rated maximum
   • Propane-only fuel compatibility
   • Requires a compatible cutout approximately half an inch larger than the pan

   Best for: First-time DIYers fitting a compact round propane insert into a custom table and looking for included ignition and tank connections.

   Not ideal for: Buyers who need natural-gas compatibility, strong heat output for a larger gathering area, or a non-round insert.

   • Pan diameter:19 inches
   • Material:304 stainless steel
   • Weight:13.9 pounds
   • Fuel type:Liquefied petroleum gas (LPG)
   • Tank compatibility:Standard 20-pound propane tank
   • Included components:Round pan, ring burner, control valve knob, spark igniter, thermocouple probe, and regulator hose set
   Our verdict

   “Choose the WISLULU for a small, propane-only table where a bundled control and ignition setup matters more than high heat.”

   → See it on Amazon →

5. GRISUN 18 x 18 Inch Drop-in Fire Pit Kit with Glass Wind Guard & Lid

   

   Best Compact Square Kit

   View Latest Price

   The GRISUN 18-by-18-inch kit gives small fire tables a complete, square-format insert without requiring buyers to assemble a burner from separate pieces. Its wind guard, lid, and ignition system make it more package-oriented than the 18-inch Fire Ring Burner, which is only a ring and requires a compatible pan and controls. The square layout is also a better match for compact table openings than the longer 36-by-12-inch GRISUN linear kit. The tradeoff is a strict footprint: it is intended for an 18-inch square setup, and its LPG fuel type rules out natural gas. At 16.3 pounds, it is not especially light for a small insert, so planning the support and access beneath the tabletop matters.

   Pros:

   • Compact square format fits small fire-table designs
   • Includes a glass wind guard and protective lid
   • Ignition system and burner pan are included
   • Stainless steel construction with polished finish

   Cons:

   • LPG-only fuel compatibility
   • Limited to square openings sized for the 18-inch kit
   • 16.3-pound weight may complicate handling in a tight installation

   Best for: Owners of compact square propane fire tables who want an insert kit with flame protection and a cover included.

   Not ideal for: Buyers with rectangular or round openings, natural-gas supply, or a priority on minimizing installation weight.

   • Dimensions:18 x 18 x 2 inches
   • Weight:16.3 pounds
   • Material:Stainless steel
   • Finish:Polished
   • Fuel type:LPG
   • Included features:Burner, pan, glass wind guard, lid, and ignition system
   Our verdict

   “Pick this GRISUN for a compact square propane table when a bundled wind guard and lid are more useful than a long flame layout.”

6. Stanbroil Stainless Steel 30-Inch Round Flat Fire Pit Pan

   

   Best High-Output Round Pan

   View Latest Price

   For a round fire pit build where burner capacity matters more than portability, the Stanbroil 30-inch pan pairs a 24-inch ring with a listed output of up to 296,000 BTU. Its 304 stainless steel construction and polished finish suit an exposed outdoor installation, while the flat, 2-inch profile can fit a suitable custom enclosure. Compared with the Hiorucet 12-inch kit, this is a much larger, higher-output option, but Hiorucet includes an igniter and propane hoses, which this Stanbroil pan does not.

   The main tradeoff is that it is a component for a fixed fire-pit setup, not a self-contained portable unit. It supports propane or natural gas, but the product data does not include an igniter, so buyers may need to source compatible ignition and gas components separately. Its 30-inch round footprint also calls for a properly sized enclosure.

   Pros:

   • 24-inch burner ring paired with listed output up to 296,000 BTU
   • 304 stainless steel construction is suited to outdoor use
   • Low 2-inch pan profile can suit compatible custom enclosures
   • Supports both propane and natural gas

   Cons:

   • Igniter is not included, so additional components may be needed
   • Requires a fixed gas connection and is not a portable setup
   • A 30-inch round pan needs a suitably sized enclosure

   Best for: DIY builders fitting a large round fire pit who want a high-output pan and already have, or plan to source, compatible gas and ignition components.

   Not ideal for: Buyers seeking a portable propane fire pit or a complete kit with an included igniter and hoses; consider the Hiorucet kit for a smaller, more complete propane setup.

   • Pan diameter:30 inches
   • Burner ring diameter:24 inches
   • Material:304 stainless steel
   • Finish:Polished
   • Fuel:Natural gas or propane
   • Maximum output:296,000 BTU
   • Weight:10 pounds
   • Dimensions:30 x 30 x 2 inches
   Our verdict

   “Choose this Stanbroil pan for a large, fixed round build where high burner output matters more than an all-in-one kit.”

   → See it on Amazon →

7. Onlyfire 36″ Square Fire Pit Flat Pan with Burner Ring, 435,000 BTU

   

   Best for Large, High-Output Builds

   View Latest Price

   The Onlyfire 36-inch square pan is the lineup’s high-capacity choice, with a listed 435,000 BTU output and a pre-installed square burner. That scale makes it a stronger fit for a large outdoor feature than the Onlyfire 24-inch square pan, whose listed output is 147,000 BTU and whose smaller footprint suits more modest builds. The 304 stainless steel construction and drop-in design support a DIY installation, but the 38-inch overall dimensions and 33-pound weight mean the enclosure and handling plan need to match.

   Propane buyers should pay close attention to the setup requirements: an air mixer is sold separately, and the product description notes that outer gas outlets may not show a visible flame, calling for external ignition. This is not the simplest route to a ready-to-light fire pit; it makes more sense for builders prepared to source and fit the extra components.

   Pros:

   • Listed 435,000 BTU output for a high-capacity build
   • Pre-installed square burner simplifies part of the drop-in installation
   • 304 stainless steel construction
   • Works with natural gas or propane when set up with compatible components

   Cons:

   • Propane use requires a separately purchased air mixer
   • At 33 pounds, it may take more than one person to position safely
   • External ignition may be needed, and some outlets may not show visible flame

   Best for: DIY builders creating a large square outdoor fire feature who prioritize high listed burner output and can handle a heavy pan and separate propane components.

   Not ideal for: Buyers with compact enclosures, limited installation experience, or a preference for a complete propane kit; the smaller Hiorucet kit includes hoses and an igniter.

   • Fire-pit size:36 inches
   • Overall dimensions:38 x 38 x 2 inches
   • Material:304 stainless steel
   • Weight:33 pounds
   • Maximum output:435,000 BTU
   • Fuel compatibility:Natural gas or propane
   • Burner shape:Square
   Our verdict

   “Pick this Onlyfire when you have room for a large square insert and are prepared to manage its weight and separate propane setup parts.”

   → See it on Amazon →

8. Onlyfire 18″ Square Fire Pit Burner Ring for Natural Gas/Propane

   

   Best Compact Burner Ring

   View Latest Price

   When the project calls for a burner rather than a full drop-in pan, this 18-inch square ring keeps the component compact and weighs just 3.2 pounds. Its 147,000 BTU listing gives it substantially more stated output than the Hiorucet 12-inch ring kit, though Hiorucet is the more ready-to-connect option because it includes an igniter and propane hoses. The square geometry gives a DIY fire pit a different flame layout from round rings, and 304 stainless steel is suited to demanding fire-pit conditions.

   This is a focused component, not a complete propane installation. An air mixer is needed for propane, and buyers must confirm that the ring fits their enclosure, which should be no larger than the stated 19-inch maximum compatible size. Installation may call for gas-system knowledge; choose a complete kit instead if you do not want to source additional parts.

   Pros:

   • Compact 18-inch square shape for smaller compatible builds
   • 304 stainless steel construction
   • Listed 147,000 BTU output
   • Supports natural gas or propane with the appropriate setup

   Cons:

   • Propane use requires an additional air mixer
   • Burner ring only; it does not include a pan, igniter, or hoses
   • Limited size may not suit larger fire-pit enclosures

   Best for: DIY builders with a compact, square fire-pit enclosure who want a lightweight burner ring and can provide the required propane mixing and connection components.

   Not ideal for: Buyers wanting a drop-in pan, a larger flame footprint, or an included igniter and hose setup; the Hiorucet kit includes more of the connection hardware.

   • Shape:Square
   • Size:18 inches
   • Maximum compatible size:19 inches
   • Material:304 stainless steel
   • Output:147,000 BTU
   • Fuel:Natural gas or propane
   • Dimensions:18 x 18 x 0.65 inches
   • Weight:3.2 pounds
   Our verdict

   “Choose this ring for a compact square DIY build if you already know how to supply its separate gas and ignition components.”

   → See it on Amazon →

9. Hiorucet 12 Inch Fire Pit Burner Ring Kit with Igniter and Propane Hose

   

   Best Complete Propane Starter Kit

   View Latest Price

   Among these options, the Hiorucet 12-inch kit is the clearest pick for a buyer who wants the core propane connections included rather than assembling a parts list. It comes with an igniter and two hose sections, alongside a 304 stainless steel round burner rated up to 92,000 BTU. That output is well below the Stanbroil 30-inch pan’s listed 296,000 BTU, but Hiorucet is much smaller and bundles more of the basic connection hardware. Its drilled holes are described as supporting even flame distribution and quiet operation.

   The tradeoff is limited flexibility: this kit is propane-only, and its 12-inch burner suits smaller builds rather than a broad fire feature. Assembly still calls for some technical ability, so included parts should not be mistaken for a fully assembled, plug-and-play appliance. Buyers planning a natural-gas installation or a larger enclosure should choose a different format.

   Pros:

   • Includes an igniter and propane hose components
   • 304 stainless steel burner construction
   • Listed output up to 92,000 BTU for a compact setup
   • Round drilled-hole design is intended to provide even, quiet flames

   Cons:

   • Propane only, with no natural-gas compatibility
   • 12-inch diameter limits the scale of the fire feature
   • Assembly may require technical skills

   Best for: First-time DIY builders making a compact propane fire pit who want an included igniter and hose setup and do not need natural-gas compatibility.

   Not ideal for: Buyers building a large fire feature or needing natural-gas support; the Stanbroil 30-inch pan offers a much larger burner format and supports either fuel.

   • Burner diameter:12 inches
   • Material:304 stainless steel
   • Fuel:LPG (propane)
   • Maximum output:92,000 BTU
   • Weight:3.15 kg
   • Connect hose length:4 feet
   • Regulator hose length:4.4 feet
   Our verdict

   “Choose Hiorucet for a small propane DIY build when an included igniter and hoses matter more than high output or fuel flexibility.”

10. Onlyfire 24″ Square Fire Pit Flat Pan with Burner Ring, 147,000 BTU

    

    Best Mid-Size Square Pan

    View Latest Price

    The Onlyfire 24-inch square pan balances a built-in pan format with a more manageable footprint than the 36-inch Onlyfire model. Its listed 147,000 BTU output gives it a substantial burner for a mid-size square build, while the stainless steel pan can be dressed with fire glass to change the finished look. At 13.9 pounds, it is also considerably lighter than the Onlyfire 36-inch pan, though its 28.5-inch overall width still calls for a properly sized enclosure.

    Its main compromise appears with propane: an air mixer valve is required, and additional installation accessories may be needed. Unlike the Hiorucet kit, this product data does not list an included igniter or hose setup. It supports natural gas as well as propane, but buyers seeking a complete small propane kit or a round burner should compare other options before building around this square pan.

    Pros:

    • Drop-in pan and burner ring form a square insert assembly
    • Listed 147,000 BTU output
    • Supports natural gas or propane with the appropriate components
    • Fire glass can be used to customize the finished appearance

    Cons:

    • Propane use requires a separate air mixer valve
    • Additional accessories may be needed for installation
    • Square shape will not fit a round enclosure

    Best for: DIY builders with a mid-size square enclosure who want a drop-in pan, natural-gas or propane compatibility, and the option to finish the burner with fire glass.

    Not ideal for: Buyers wanting a complete propane kit with included hoses and igniter, or those building a round fire pit; Hiorucet includes more connection components, while the Stanbroil pan is round.

    • Shape:Square
    • Pan dimensions:28.5 x 28.5 x 4.5 inches
    • Material:Stainless steel
    • Fuel:Natural gas or propane
    • Output:147,000 BTU
    • Weight:13.9 pounds
    • Color:Silver
    • Item count:1
    Our verdict

    “Choose this Onlyfire pan for a mid-size square build if you can supply the propane mixer and any other installation parts separately.”

11. Stanbroil 31 Inch Drop-in Round Fire Pit with Spark Ignition Kit

    

    Best for High-Output Round Builds

    View Latest Price

    For a round insert where flame strength matters more than fuel flexibility, I’d put this Stanbroil near the front of the list. Its 24-inch 304 stainless steel burner ring is rated up to 296,000 BTU, far above the 150,000-BTU VEVOR rectangular pan, making it the stronger fit for a larger fire feature. The included spark ignition system also means less sourcing of lighting components than with the Stanbroil 48 x 14 Inch Rectangle Drop-in Fire Pit H-Burner Pan, which has an igniter mounting plate but no igniter. The tradeoffs are a propane-only setup and a substantial 33.4-inch overall footprint. I’d choose it for a roomy DIY island, but skip it if the opening is compact or you want natural-gas compatibility.

    Pros:

    • 304 stainless steel burner construction
    • Burner rated up to 296,000 BTU
    • Spark ignition system is included
    • Round drop-in design suits fire-glass installations

    Cons:

    • Propane only, unlike the dual-fuel Stanbroil 48 x 14 Inch Rectangle Drop-in Fire Pit H-Burner Pan
    • Requires DIY installation and a suitable propane connection
    • Large footprint and 25-pound weight can complicate fitting and handling

    Best for: DIY builders creating a spacious round propane fire feature who want a high-output burner and included spark ignition.

    Not ideal for: Buyers with small openings, a natural-gas line, or limited ability to handle a 25-pound insert and arrange gas connections.

    • Overall dimensions:33.4″ D x 33.4″ W x 2″ H
    • Weight:25 pounds
    • Material:304 stainless steel
    • Fuel type:LPG (propane)
    • Burner ring diameter:24 inches
    • Maximum burner output:296,000 BTU
    • Ignition:Spark ignition system included
    Our verdict

    “Choose this Stanbroil for a roomy round propane build where high burner output and included spark ignition matter more than fuel flexibility.”

12. VEVOR 36 x 12 inch Drop-in Fire Pit Pan, Rectangular Stainless Steel Fire Pit Burner Kit, Propane Fire Pan 150,000 BTU with H-Burner for Indoor or Outdoor Use

    

    Best for a Complete Rectangular Kit

    View Latest Price

    I’d shortlist the VEVOR when a 36 x 12-inch rectangular cutout and a bundled burner setup are the main priorities. Its 150,000-BTU H-burner is less powerful than the Stanbroil 31 Inch Drop-in Round Fire Pit’s 296,000-BTU ring, but the long, narrow format can suit a linear table without committing to a round opening. The package includes CSA-certified accessories, and the listed SUS304 burner material adds corrosion resistance where the flame hardware takes heat. Its pan body is SUS201, however, so it is not all 304 stainless steel. The propane-only fuel setup also limits conversion choices. Compared with the Skyflame 30 x 10 Inch Rectangular Fire Pit Pan Kit, this is wider and longer, but it calls for a matching installation opening.

    Pros:

    • Long rectangular format suits linear fire tables
    • 150,000-BTU H-burner provides substantial output
    • Burner is SUS304 stainless steel
    • Includes CSA-certified accessories and installation instructions

    Cons:

    • Propane-only fuel compatibility
    • Pan body is SUS201 rather than 304 stainless steel
    • 36 x 12-inch installation size will not fit smaller openings

    Best for: DIYers with a 36 x 12-inch rectangular fire-table opening who want a propane H-burner kit with specified safety-certified accessories.

    Not ideal for: Buyers needing a compact insert, natural-gas compatibility, or a pan made entirely from 304 stainless steel.

13. Stanbroil 48 x 14 Inch Rectangle Drop-in Fire Pit H-Burner Pan

    

    Best for Natural-Gas Flexibility

    View Latest Price

    This Stanbroil earns a distinct place for buyers who want to choose between propane and natural gas rather than lock a fire feature to one fuel. Its 48 x 14-inch H-burner pan is larger than the VEVOR 36 x 12-inch model, giving builders a better match for a broad rectangular opening; its 185,000-BTU ceiling also exceeds the VEVOR’s 150,000 BTU. That flexibility comes with a more bare-bones setup: the igniter is not included, despite a mounting plate, and fire glass is required separately for the intended decorative finish. I’d favor it over the propane-only Skyflame 30 x 10 Inch Rectangular Fire Pit Pan Kit when fuel choice and a larger format matter more than included ignition hardware or a compact footprint.

    Pros:

    • Compatible with propane and natural gas
    • 304 stainless steel construction
    • 185,000-BTU maximum output
    • Includes a mounting plate for an igniter

    Cons:

    • Igniter is not included
    • Fire glass must be purchased separately
    • 50.5-inch width requires a large installation area

    Best for: Builders planning a large rectangular fire table who may use either propane or natural gas and are comfortable sourcing ignition and fire media separately.

    Not ideal for: Buyers seeking a ready-to-light kit, an included igniter, or an insert for a short or narrow opening.

    • Material:304 stainless steel
    • Dimensions:16.5″ D x 50.5″ W x 2″ H
    • Weight:18.9 pounds
    • Maximum output:185,000 BTU
    • Fuel types:Propane and natural gas
    • Burner type:H-burner
    • Top flange:1 1/4 inches
    • Inlet size:1/2 inch
    Our verdict

    “Choose this Stanbroil for a large rectangular build where dual-fuel capability outweighs the need to buy ignition hardware and fire glass separately.”

14. Onlyfire 18″ Square Fire Pit Burner Pan with Square Burner Ring, 92,000 BTU

    

    Best Compact Square Burner

    View Latest Price

    When a small fire table needs a square flame pattern rather than a long linear burner, I’d look at this Onlyfire. Its 18-inch square layout is more compact than the 30 x 10-inch Skyflame pan, and its 92,000-BTU output is a more restrained choice than the high-output Stanbroil 31 Inch Drop-in Round Fire Pit. It also supports natural gas or propane, though propane use requires a separate air mixer, so this is not the simplest route for a buyer wanting a self-contained kit. The pan needs at least two inches of depth for fire glass or lava rock, and gas connection parts are not included. I’d select it for a custom square DIY build, not for someone who wants to unpack one box and light a finished assembly.

    Pros:

    • Compact square format fits smaller custom fire tables
    • 92,000-BTU output suits a more modest flame
    • 304 stainless steel resists rust
    • Supports natural gas and propane with the required setup

    Cons:

    • Propane requires a separate air mixer
    • Gas source and connection components are not included
    • Requires at least 2 inches of depth for fire glass or lava rock

    Best for: DIY builders making a compact square fire table who want a choice of natural gas or propane and can supply the needed connections.

    Not ideal for: Buyers who want included gas hardware, a shallow media bed, or a high-output burner for a broad fire feature.

    • Size:18 inches
    • Shape:Square
    • Output:92,000 BTU
    • Material:304 stainless steel
    • Fuel compatibility:Natural gas and propane
    • Inlet:1/2-inch NPT
    • Propane requirement:Separate air mixer required
    Our verdict

    “Choose this Onlyfire for a compact square DIY build if you can provide the gas hardware and meet its media-depth requirement.”

15. Skyflame 30 x 10 Inch Rectangular Fire Pit Pan Kit, Stainless Steel

    

    Best for a Ready-to-Assemble Narrow Pan

    View Latest Price

    The Skyflame is the more convenient pick for a narrow rectangular propane build because it includes a spark ignition kit and propane hose, along with the pan and burner. That makes it a more bundled option than the Stanbroil 48 x 14 Inch Rectangle Drop-in Fire Pit H-Burner Pan, which supports natural gas as well as propane but leaves the igniter and fire glass to the buyer. Skyflame’s 30 x 10-inch pan also needs less length than the VEVOR 36 x 12-inch model, though its output tops out at 125,000 BTU, below both. The listed fuel type is propane; natural-gas conversion needs an additional hose, so I wouldn’t choose it for a natural-gas-first installation. Its value is simpler assembly, not fuel versatility or maximum heat.

    Pros:

    • 30 x 10-inch rectangular format fits narrower builds
    • 304 stainless steel construction
    • Includes spark ignition kit and propane hose
    • Includes pan, burner, and assembly hardware

    Cons:

    • Listed for propane, with natural-gas conversion requiring an additional hose
    • 125,000-BTU output is lower than the VEVOR and Stanbroil rectangular alternatives
    • Fire glass or lava rock is not listed among the included components

    Best for: DIYers building a narrow rectangular propane fire feature who want the ignition kit and propane hose included.

    Not ideal for: Buyers prioritizing natural-gas use, a larger installation footprint, or more output than 125,000 BTU.

    • Material:304 stainless steel
    • Pan size:30 x 10 inches
    • Item dimensions:10″ D x 32.5″ W x 2″ H
    • Maximum output:125,000 BTU
    • Fuel type:Propane
    • Shape:Rectangular
    • Included components:Fire pit pan, burner, spark ignition kit, propane hose
    Our verdict

    “Pick the Skyflame for a narrow propane fire table when included ignition and hose matter more than natural-gas flexibility or higher output.”

How We Picked

I evaluated these propane fire pit inserts based on build quality, heat distribution, and ease of installation. Since these components are often hidden beneath lava rocks or fire glass, material thickness and corrosion resistance were primary filters; thin-gauge aluminum pans that warp under sustained heat were excluded immediately. I also prioritized inserts that offer clear compatibility with standard 20 lb propane tanks and common fire pit table dimensions, as mismatched sizing is the most frequent cause of installation failure.

The ranking logic places versatility and durability above raw BTU count. A burner that produces excessive heat but fails to distribute it evenly creates an uncomfortable gathering space. Products with integrated ignition kits received a slight boost in ranking for user convenience, provided the ignition module is accessible for battery replacement. Finally, I considered the availability of replacement parts, favoring brands with widespread availability of hoses, regulators, and burner heads.

Factors to Consider When Choosing Best Propane Fire Pit Inserts

Selecting the right propane insert is a matter of matching thermal output to spatial dimensions. Unlike pre-assembled fire pits, inserts offer customization, but this freedom places the burden of compatibility squarely on the buyer.

Matching BTU Output to Pit Size

It is not enough to pick the highest BTU rating available. Propane BTUs measure heat output, but the efficiency of that heat depends on the pit’s volume. A small 12-inch pan in a large 48-inch rectangle will create a cozy campfire effect but fail to warm the seating area. Conversely, a massive 150,000 BTU unit in a small, enclosed patio can create dangerous heat reflection and scorching on nearby furniture. I recommend calculating your pit’s surface area and aiming for 500-700 BTUs per square foot for adequate warmth without excessive fuel consumption.

Burner Shape and Heat Distribution

Round burner rings are the most common and affordable, but they often leave corners of rectangular tables cold. H-burners and cross-shaped burners are engineered to push flame into the far reaches of rectangular pans. If you are building a rectangular pit longer than 30 inches, a simple ring burner will likely underperform. I found that inserts featuring H-burner designs provide a more consistent flame pattern, which is critical when using glass fire media that reflects heat back toward the user.

Material Durability and Corrosion Resistance

Since these inserts sit under fire media, they are exposed to constant thermal cycling and moisture from rain or condensation. 304 stainless steel is the gold standard here, resisting rust and warping far better than coated steel or aluminum. Cheaper inserts often use thinner gauge metal that may last one or two seasons before developing cracks or hot spots. I prioritize pans with a thickness of at least 1.2mm to 1.5mm, as this prevents the pan from expanding and contracting enough to break the seal around the gas line.

Ignition Systems and Maintenance

Many modern inserts come with piezo ignition or electronic spark ignition kits. While convenient, these systems rely on batteries and small electronic modules that can fail due to moisture ingress. If you prioritize low maintenance, a manual ignition setup with a long lighter is more reliable. However, if you choose an electronic ignition, ensure the igniter button is accessible outside the fire media layer. I recommend checking if the ignition module is replaceable without removing the entire pan, as this simplifies long-term ownership.

Regulator Compatibility and Safety

Most inserts ship with a standard regulator, but high-output units may require a high-pressure regulator to maintain flame stability. Using an undersized regulator can lead to flame roll-out or soot buildup. Always verify that the insert’s recommended regulator matches your propane tank’s output. I also check for excess flow valves in the regulator, which automatically shut off gas if a hose is cut or disconnected, adding a critical layer of safety for families with children or pets.

Frequently Asked Questions

Can I use any propane insert in any fire pit table?

No, compatibility is strictly determined by the internal dimensions of your fire pit table. You must measure the interior width and length of the bowl, not the outer edges. The insert should fit with at least 2-3 inches of clearance on all sides to allow for proper airflow and to prevent heat from damaging the table’s liner or decorative stones. Attempting to force a larger insert into a smaller space can obstruct ventilation, leading to incomplete combustion and carbon monoxide risks.

Do I need a wind guard for a propane fire pit insert?

While not strictly required for the insert to function, a glass wind guard significantly improves performance. Propane flames are lighter and more susceptible to wind disruption than wood fires. Without a guard, wind can blow the flame sideways, causing uneven heating and potentially exposing the burner pan’s sides to direct flame contact, which may damage the finish over time. The guard also contains sparks and embers, enhancing safety in open-air settings.

Why is my propane fire pit flame height low?

Low flame height is often caused by a faulty or incompatible regulator, especially if you have recently switched to a larger burner pan. The standard regulator included with many inserts is calibrated for lower BTU outputs. If you installed a high-output pan, the regulator may be restricting gas flow. Another common cause is a blocked burner orifice due to debris or insect nests. Checking the orifice and upgrading the regulator usually resolves this issue without replacing the entire insert.

How do I clean a propane fire pit insert?

Regular cleaning involves removing the fire media and washing it with soap and water to remove soot and dust. For the burner pan itself, use a soft brush to clear debris from the burner ports. Never use high-pressure water or abrasive scrubbers, as these can damage the burner holes or the protective coating. I recommend checking the burner ports for blockages at least once per season, as clogged ports can cause irregular flame patterns and soot buildup on the media.

Is stainless steel or cast iron better for a fire pit insert?

For propane inserts, stainless steel is generally superior due to its resistance to rust and its ability to handle thermal expansion without cracking. Cast iron is heavier and retains heat well, but it is prone to rusting if the protective seasoning is damaged, and it can crack under rapid temperature changes. Stainless steel pans, particularly those made from 304 grade, offer the best balance of durability, weight, and corrosion resistance for outdoor environments exposed to the elements.

Conclusion

Choosing the right propane fire pit insert depends on your specific build requirements. For most homeowners building a standard round pit, the Stanbroil 31-Inch Round Fire Pit Burner Pan offers the best blend of size, durability, and ease of installation. If you are constructing a large rectangular table and want maximum heat coverage, the GRISUN Upgraded 36 x 12 Inch Rectangular Kit is the superior choice for its H-burner design. Beginners or those with smaller spaces should consider the Hiorucet 12 Inch Fire Pit Burner Ring Kit for its compact footprint and integrated ignition. Prioritize material thickness and BTU alignment with your pit’s volume to ensure a safe, efficient, and long-lasting outdoor heating solution.
