2026 Fire Pit Burner Guide

Fire Pit Burners Explained: How to Choose the Right Burner for Your Fire Feature

If you're specifying or building a gas fire feature, burner selection needs to happen before the countertop is cut, the masonry opening is finished, or the gas system is finalized. The right burner is not simply the largest one that fits. It has to work with the shape of the feature, the pan, the available gas supply, the ignition system, the fire media, and the way the finished feature will be serviced.

American Fire Products recommends starting with the fire-feature shape and usable dimensions, deciding between a burner pan and burner-only installation, then verifying fuel, gas supply, ignition, drainage, ventilation, and service access before fabrication is complete.

One of the biggest sources of jobsite confusion is terminology. A fire pit pan is not another burner shape competing with a ring burner or H-burner. The burner creates the flame. The pan supports the burner and fire media. In many installations, the two are designed to work together.

American Fire Products has helped contractors, builders, designers, dealers, and homeowners specify gas fire features since 2005. This guide is built around the same questions our team wants answered before recommending a burner system. If you're still planning the entire project, start with The Complete Fire Pit Planning Guide for 2026, then use this guide to narrow the burner.

Fire Pit Burners at a Glance

What's the Difference Between a Fire Pit Burner and a Burner Pan?

The burner releases gas and creates the flame. The burner pan is the tray or platform that supports the burner and the decorative media surrounding it.

A ring burner, H-burner, or linear burner describes the shape or configuration of the burner itself. A fire pit pan describes the platform surrounding and supporting that burner.

You can have:

• A round pan with a ring burner
• A square pan with a round ring burner
• A rectangular pan with an H-style burner
• A linear pan with a linear burner
• A standalone ring burner without a pan
• A standalone H-burner in an approved fireplace or fire pit application

Does Every Fire Pit Need a Burner Pan?

No. A burner can be installed without a pan when the fire feature is designed for that type of installation.

But when a customer is starting a straightforward new build and has no specific reason to eliminate the pan, we usually recommend using one.

A pan gives the burner a purpose-built platform, supports the decorative media, helps create a defined media area, and can simplify the overall construction.

Why We Recommend a Fire Pit Pan for Many New Builds

For most straightforward new outdoor fire pit builds, we recommend choosing the pan first and designing the opening around it.

American Fire Products offers fire pit pans in round, square, rectangular, and linear configurations. Each pan is paired with the burner configuration intended for that shape, so you are not left trying to independently match a burner to the pan after the fact.

The pan helps:

• Support the burner
• Support fire glass, lava rock, or other approved media
• Create a defined finished media area
• Provide a repeatable component around which the fire feature can be designed
• Reduce some of the guesswork involved in burner placement

For a contractor building a countertop, masonry enclosure, or fabricated surround, that last point matters. Choosing the pan first gives you a known component to design around. The fabricator gets a real opening requirement, the gas installer gets a known burner load, and the finished feature is not limited to whatever happens to fit after the fact.

When Would We Not Automatically Use a Pan?

A pan is not required in every custom fire feature.

A burner-only installation may make sense when:

• The enclosure is specifically designed to support the approved media without a pan
• The project already has an existing suitable structure
• A standalone burner is specifically called for by the design
• An approved fireplace installation requires a different burner configuration
• The manufacturer or project specification calls for another arrangement

For a new build with no special design constraint, the pan is usually the simplest place to start.

Start with the Fire Pit Pans collection to compare the available shapes and installation styles.

Drop-In Fire Pit Pan vs. Flat Pan

The difference is how the pan is supported by the fire feature. A drop-in pan sits in a prepared opening and is supported around its perimeter, while a flat pan is designed for an installation where the surrounding structure provides the appropriate support beneath it.

When We Prefer a Drop-In Pan

For many new builds, especially countertop-style fire pits, the drop-in configuration is the easiest to understand and plan around.

The installer creates the proper opening, the pan drops into that opening, and the outer flange supports the pan around the perimeter.

This is often our first recommendation while the fire feature is still being designed because the structure can be built around the selected pan instead of the other way around. Before the countertop or cap is fabricated, verify the exact cutout dimensions on the product page and installation instructions.

When a Flat Pan Makes Sense

A flat pan can make sense when the fire feature construction provides a suitable surface or support system for that configuration.

They're often useful in custom installations where a drop-in flange is not needed or where the pan will sit on an appropriately designed ledge or support. American Fire Products offers both round and rectangular flat-pan configurations. Explore Fire Pit Pans to compare the available shapes and installation styles.

Fire Pit Ring Burners

A fire pit ring burner is a circular gas burner designed to create flame around one or more circular rings. It is the configuration we most commonly associate with round fire pits.

Ring burners are a natural fit for round fire features. They are also used inside American Fire Products square burner-pan systems, which is why a square fire pit does not require a square-shaped burner.

Where Ring Burners Make the Most Sense

• Round fire pits
• Round fire bowls
• Square pans designed around a circular burner
• Custom burner-only installations where a centered circular flame pattern fits the design

Can You Use a Round Ring Burner in a Square Fire Pit?

Yes. A square fire pit does not require a square burner.

American Fire Products' square drop-in pans pair a square pan with a round ring burner. The pan follows the architecture of the fire feature while the ring creates the flame pattern.

That's one of the clearest examples of why the pan and burner should be considered separately.

How Do You Size a Ring Burner?

Choose the ring burner from the usable inside dimensions and the requirements of the specific enclosure or pan. If you're buying a complete American Fire Products pan system, use the burner supplied with or specified for that pan.

If the enclosure is being built specifically around a standalone burner, review the Fire Pit Ring Burners before finalizing the inside dimensions. For a new round drop-in installation, compare that burner-only route with the Fire Pit Pans collection.

H-Burners: A Strong Choice for Fireplaces and Rectangular Flame Coverage

When contractors call American Fire Products about a standalone H-burner, the project is often a fireplace upgrade. That is the application we most commonly associate with this burner shape, but it is not the only one.

An H-burner spreads flame across a wide rectangular area, which makes it a natural fit for many fully vented natural gas fireplaces. It can also be used in suitable rectangular outdoor fire features, while American Fire Products rectangular fire pit pans use H-style burner configurations for outdoor pan-based installations.

Why Choose an H-Burner?

The two parallel burner runs help spread flame across a wider area, which is why the configuration works so well in rectangular fireboxes and other rectangular installations.

For that reason, H-style burners are a natural fit for:

• Fully vented natural gas fireplaces when the specific burner is approved for the installation
• Fireplace upgrades where a wider flame pattern is desired
• Rectangular outdoor fire features designed for a standalone H-burner
• Rectangular burner pans that use an H-style burner configuration

H-Burner vs. Ring Burner

Use the shape of the fire feature to make the first decision.

For an outdoor round fire pit, we'd usually begin with a ring burner. For a fireplace, an H-burner is often the more natural starting point. For a rectangular outdoor fire pit, we generally prefer a rectangular pan with its built-in H-style burner configuration.

A round burner can physically fit in many rectangular openings. That doesn't mean it creates the best flame pattern.

Can an H-Burner Be Used in a Fireplace?

Yes, when the specific burner and fireplace installation permit it.

American Fire Products' current standalone stainless steel H-burners are natural-gas burners. They are commonly used in fully vented natural gas fireplaces with a chimney and flue, and they may also be used in properly designed outdoor fire pits.

Follow the required clearances, product instructions, and applicable codes for the exact H-burner and installation.

Do not take that as approval to put any outdoor burner into any indoor fireplace. Indoor applications require the correct appliance, ventilation, fuel, clearances, and product approval.

Linear Burners for Long, Narrow Fire Features

When the fire feature is long and narrow, the burner should usually follow that long profile.

That is where a linear burner configuration makes more sense than a circular burner.

American Fire Products Fire Pit Pans include linear configurations that use built-in linear burners designed specifically for long, narrow installations.

Why Not Just Put a Ring Burner in the Middle?

You can physically center a round burner in many long rectangular openings. The problem is what happens visually.

You may end up with a large fire feature where most of the media bed has no flame and all of the fire is concentrated in the center.

A linear burner extends the flame along the length of the feature so the finished fire looks proportional to the structure.

Linear vs. Rectangular: What's the Difference?

Both may look rectangular from the outside, but the proportions matter.

Use a standard rectangular configuration when the fire feature has meaningful width and you want flame spread across that rectangular area. Use a linear configuration when the fire feature is especially long relative to its width.

For projects where push-button or automated ignition is part of the specification, linear configurations are also available through the Spark Ignition Kits, Electronic Ignition Kits, and CSA-Certified Burner Pan Kits.

How Do You Choose the Right Fire Pit Burner Size?

The right burner size is determined by more than the opening dimensions. You also need to account for the pan, required clearances, desired flame coverage, fuel supply, BTU demand, and ignition system.

Before choosing a size, know:

• The usable inside dimensions of the fire feature
• The required cutout or support dimensions if you're using a pan
• The burner dimensions
• The required clearance around the specific burner
• The burner's listed BTU demand
• Your fuel type
• Your available gas supply
• The ignition system
• The approved media configuration

Why We Don't Use One Universal Burner Formula

Customers frequently ask for a simple rule such as, “I have a 36-inch fire pit, so what size burner do I need?”

The outside diameter alone is not enough.

A 36-inch fire pit can have a much smaller usable opening depending on wall thickness, coping, pan design, ventilation, and construction.

That's why we want the inside usable dimensions, not just the outside measurement.

Build Around the Burner System

If you're still in the design phase, choose the pan and burner before finalizing the masonry opening, countertop cutout, or fabricated surround.

That gives the contractor, fabricator, and gas installer the same set of known requirements instead of three different assumptions. The Complete Fire Pit Planning Guide covers the broader sequence, including ventilation, drainage, wind, electrical needs, and accessories.

Bigger Isn't Always Better: BTUs and Gas Supply Matter

Do not choose the largest burner that physically fits and assume the rest will take care of itself.

A larger burner can require significantly more gas. If the fuel system cannot provide the volume the burner needs, the fact that the burner fits inside the opening doesn't help.

Before finalizing the burner, confirm that the gas system can support the required BTU load.

What Can Affect Burner Performance?

• Burner size and design
• Listed BTU requirements
• Gas-line sizing
• Length of the gas run
• Available gas pressure and volume
• Natural gas vs. propane
• Regulators, valves, mixers, and other system components
• Ignition system requirements

The burner specification and gas-line design need to meet before installation day. The contractor does not need to size the gas system from this article, but the person responsible for the gas line needs the burner's actual requirements before the system is finalized. For the broader build sequence, see How to Build a Gas Fire Pit the Smart Way.

Natural Gas vs. Propane

Choose the fuel type before ordering the burner system.

Some American Fire Products burner systems are offered in both natural gas and propane configurations. Others are fuel-specific, so confirm the exact product before ordering.

Propane installations may require components such as an air mixer that are not used in the same way on natural-gas systems. The ignition kit, regulator, hose, valve, burner, and complete system need to be appropriate for the selected fuel.

American Fire Products' current standalone H-burners are natural-gas products.

Never assume that because two burners look physically identical, one can simply be switched from natural gas to propane without the correct components or instructions.

Choosing an Ignition System

Choosing the burner shape is only one part of specifying the complete fire pit system. Contractors should decide how the customer will light and control the feature before the enclosure is closed up.

Match-Lit / Manual Ignition

Best for: straightforward installations where simplicity and cost are the priority.

A match-lit system is manually ignited using a long lighter or match while the gas is controlled through the appropriate valve.

There is no electronic ignition hardware to power or control, which keeps the system relatively simple.

Spark Ignition

Best for: customers who want push-button lighting without a hardwired electronic ignition system.

American Fire Products spark ignition kits use a battery-powered push-button igniter to create the spark that lights the gas.

This gives you more convenience than manual match lighting without requiring household electrical power for the ignition spark.

Explore Spark Ignition Kits

Electronic Ignition

Best for: projects where automated control, flame-sensing safety features, or more advanced operation is desired.

American Fire Products offers electronic ignition systems including All-Weather Electronic Ignition System configurations. Depending on the system, operation may be integrated with switches, timers, or compatible controls.

These systems involve both gas and electrical components and should be installed according to the manufacturer's requirements by a qualified professional.

Explore Electronic Ignition Kits or read The AWEIS Advantage for a deeper look at all-weather electronic ignition.

CSA-Certified Burner Pan Systems

Best for: projects where a certified complete burner-pan system is desired or required.

American Fire Products also offers CSA-certified burner pan kits in select shapes and sizes. Current systems include safety shutoff features and are available in multiple burner-pan configurations.

Check the exact product for its fuel setup, conversion options, ignition details, and installation requirements.

Fire Glass and Lava Rock Over the Burner

The decorative media is part of the finished burner system, but it should be chosen after you understand what the burner and ignition system allow.

Fire glass and fire-rated lava rock are two of the most common media choices for gas fire features.

Fire Glass

Fire glass is commonly chosen when the goal is a polished, colorful, contemporary finish. Explore the Fire Glass collection.

The amount and depth should be based on the actual fire feature and burner system rather than a one-size-fits-all rule.

For the complete buying process, read The Ultimate Fire Glass Buying Guide (2026).

Lava Rock

Lava rock provides a natural volcanic appearance and can also be used as an approved base layer in many fire-feature installations. Explore the Lava Rock collection.

The correct size and placement still need to match the burner and appliance instructions.

For the full buying and sizing guide, see The Ultimate Lava Rock Buying Guide (2026).

Fire Glass vs. Lava Rock

If you're still deciding between the two, read Fire Glass vs. Lava Rock.

Once you know what media you're using, use the American Fire Products Fire Glass & Lava Rock Calculator to estimate the quantity for the actual fill area.

Existing Fire Pits and Fireplaces

Existing installations need to be evaluated differently from new construction because the opening, gas connection, ventilation, drainage, and access points are already established.

Existing Fire Pit

Document the usable interior dimensions, current fuel, gas connection, ventilation, drainage, support structure, and service access before recommending a replacement. Photos and inside dimensions are far more useful than outside dimensions alone.

Then determine which current burner or pan configurations fit the existing construction and meet the requirements of the specific system.

Existing Fireplace

Fireplaces require a burner specifically designed and approved for the application. Do not move a fire pit burner indoors.

American Fire Products' standalone H-burners are commonly used in fully vented natural-gas fireplaces with a chimney and flue when the specific burner, fireplace, clearances, and applicable codes support the installation.

Four Burner Mistakes That Create Rework

Most burner problems on contractor-built projects start before ignition. They show up as a cutout that does not match the pan, a gas line that cannot support the burner, inaccessible controls, or the wrong flame pattern for the feature.

1. Building the Opening Before Choosing the System

Choose the burner and pan first whenever possible, then fabricate the opening around the actual product dimensions and requirements.

2. Choosing Burner Size Before Verifying Gas Supply

The largest burner that fits is not automatically the right burner. Confirm BTU demand and available gas supply before finalizing the size.

3. Using the Wrong Burner Configuration for the Feature

A ring burner may physically fit a wide rectangle or long linear feature, but that does not mean it will create the flame coverage the project needs. Match the burner configuration to the shape and proportions of the feature.

4. Leaving Ignition and Service Access Until the End

Controls, valves, wiring, ignition components, and future service access can affect the enclosure. Plan them before the feature is closed up.

Fire Pit Burner Buying Checklist

If you can answer those questions before ordering, the American Fire Products team can usually narrow the correct burner system down quickly.

Frequently Asked Questions

What type of burner is best for a fire pit?

The burner should match the shape and proportions of the fire feature. American Fire Products typically starts with a ring burner for round and suitable square applications, an H-style burner in a rectangular pan for standard rectangular fire pits, and a linear burner for long, narrow fire features.

Do I need a burner pan for my fire pit?

Not every fire pit requires a burner pan. For many straightforward new builds, American Fire Products recommends starting with a pan because it provides a purpose-built platform for the burner and approved fire media.

What is the difference between a fire pit pan and a burner?

The burner releases gas and creates the flame. The pan supports the burner and decorative fire media. A pan may contain a ring burner, H-style burner, or linear burner depending on the design.

What size fire pit burner do I need?

Size the burner from the usable interior dimensions, required clearances, pan dimensions, BTU demand, available gas supply, ignition system, and the specific manufacturer's requirements. Do not choose size from the outside dimensions alone.

Can the same burner be used for natural gas and propane?

Some burner systems are available for both fuel types, but the required components can differ. Confirm the exact configuration for the fuel before ordering.

Can I use a burner without a pan?

Yes, when the fire feature is designed for a burner-only installation. The enclosure still needs to meet the support, ventilation, drainage, media, and clearance requirements of the specific burner system.

Can an H-burner be used in a fire pit?

Yes. Standalone H-burners are commonly used in fireplaces, but they can also be used in properly designed outdoor fire features when the specific burner and installation permit it.

Can a fire pit burner be used indoors?

No. Fire pit burners are for outdoor fire pit applications. For an indoor fireplace, use a burner specifically designed and approved for that fireplace application.

Can I cover a fire pit burner with fire glass or lava rock?

Approved fire glass or fire-rated lava rock can be used with compatible burner systems. Follow the burner and ignition-system instructions for media depth and placement, and keep any components that must remain exposed clear.

What is the difference between an H-burner and a linear burner?

An H-burner spreads flame across a wider rectangular area and is commonly used in fireplaces or rectangular applications. A linear burner follows the length of a long, narrow fire feature.
