A gas fire pit is an outdoor decorative appliance that burns natural gas or propane through a burner set inside a non-combustible vessel. Residential models run roughly 45,000 to 175,000 BTU/hr, need 7″ water column of natural gas or 11″ of propane, and require 36–48 inches of side clearance and 60–120 inches overhead (see our clearance reference table by brand). Outdoor Heat Direct lists 577 fire pits from $629 to $24,832.

What’s the difference between a fire pit, a fire table and a fire bowl?
Nobody standardized these words. Manufacturers use them loosely, and two brands will call the same object different things. What actually changes between them is height, the width of the usable ledge, and whether the vessel is meant to sit alone or anchor a seating group.
The practical split is this. A fire table has a broad top you can set a drink on and usually sits at coffee-table or dining height. A fire pit is a lower vessel with a narrow rim, built to be looked into rather than used as furniture. A fire bowl is a sculptural round vessel, often mounted on a pedestal or set into hardscape, and it is frequently sold in pairs to flank a pool or a stair. Fire urns and fire towers are tall, narrow vertical features that give you flame at eye level without eating floor space.

Gas or wood burning: which should you buy?
Gas wins on control. You turn it on, you turn it off, there is no ash bucket and no smoke chasing your guests around the table. It also wins on legality in a lot of places, because many municipalities and homeowner associations restrict open wood burning outright or on declared air-quality days, while permanently installed gas appliances are treated differently.
Wood wins on two things only: no fuel infrastructure, and the sound. If there is no gas line and no appetite for a propane tank, a wood burner is the honest answer.
The trade nobody mentions: a wood fire has no off switch. Every clearance number in the next sections assumes you can shut the appliance down in a second. With wood you cannot, so treat published clearances as a floor and add margin. The Outdoor Heat Direct catalog reflects where the market went — 610 products are configured for natural gas and 680 for propane.
Natural gas or propane?
Natural gas gives unlimited runtime and no tank to hide, at the cost of a plumbed line. Nominal supply pressure is 7″ water column. Propane is portable, works anywhere, and runs at 11″ water column nominal — but you are now responsible for a 20 lb cylinder and somewhere to put it.
Run the numbers before you decide. A 20 lb cylinder holds about 4.7 usable gallons, and propane carries 91,452 BTU per gallon, so a full tank contains on the order of 430,000 BTU. On a 65,000 BTU/hr burner at full output that is about 6.6 hours of flame.1 Two long evenings. If you entertain weekly, you will be swapping tanks constantly, and that is the moment people wish they had trenched a gas line.
Propane also needs a home for the cylinder. Most vessels are sold with a door or a matching tank enclosure so the cylinder sits inside the base rather than beside it. Note that fuel type is a build option, not a switch: converting a unit after the fact usually means an orifice change and sometimes a different burner, so confirm the configuration before you order.
How many BTUs do you actually need?
BTU is a fuel consumption rating, not a comfort rating. A gas fire pit is a decorative appliance. It gives you flame presence and radiant warmth at close range, and it will not heat a patio the way an overhead radiant heater does. What BTU actually predicts is flame height and how the fire holds up in wind.
Here are real published figures rather than round marketing numbers. American Fyre Designs rates its standard V and K model fire pits at 65,000 BTU on natural gas and 60,000 BTU on propane, with its F models at 140,000 BTU on both fuels. Electronic dual-burner systems scale with diameter.
| Burner | Published rating | Reads as |
|---|---|---|
| 12″ round dual burner | Up to 90,000 BTU/hr | Compact bowl or urn |
| 18″ round dual burner | Up to 125,000 BTU/hr | Standard round fire table |
| 24″ round dual burner | Up to 150,000 BTU/hr | Large round, dominant flame |
| 30″ round triple burner | Up to 175,000 BTU/hr | Statement piece, commercial scale |
| American Fyre Designs V/K models | 65,000 NG / 60,000 LP | Typical residential fire pit |
Two things follow. First, the same appliance is usually rated slightly lower on propane than on natural gas, so do not compare a propane spec sheet against a natural gas one. Second, higher BTU means a bigger gas line and a faster tank. A 140,000 BTU unit is not simply a better 65,000 BTU unit — it is a different plumbing job. Swapping the burner later does not change that.
What shape and size fits your space?
Shape is a seating decision, not a style decision. Round pulls people into a circle and works when the fire is the center of the arrangement. Rectangular and linear units read as a coffee table between two facing sofas, or slide along a wall where a round unit would waste depth. Square splits the difference and fits corners cleanly.
| Shape | Seating it suits | Units at Outdoor Heat Direct |
|---|---|---|
| Round | Chairs in a circle, conversation groups | 58 round models |
| Rectangular / linear | Two facing sofas, wall runs, long balconies | 55 rectangular models |
| Square | Corners, four-sided seating, tight courtyards | 32 square models |
On size, measure the seating circle before you measure the vessel. You need the table footprint plus clearance on every side plus room for chairs to push back. And measure the ledge, not the top. Two 48-inch tables can have wildly different usable rims once you subtract the burner opening, and the rim is the part that holds a glass.

Talk to our teamRead the manuals firstWhat are fire pits made of, and which material lasts?
Four materials dominate, and each fails in a different way.
- GFRC (419 products): glass fiber reinforced concrete. Thinner and lighter than cast concrete at comparable strength, which is why it dominates the mid and upper market. Takes color and texture well.
- Cast concrete (389 products): heavy, dense, and honest. Hairline crazing and color variation are characteristics of the material, not defects — manufacturers say so in writing. If that will bother you, buy something else.
- Steel (123 products): powder-coated or stainless for a clean modern edge; Corten weathers to a stable rust patina on purpose. Coastal air is hard on coated steel.
- Copper (76 products): the most expensive and the most alive. It will patina, and there is no stopping it. Buy it because you want that, not in spite of it.
Whatever the body is made of, a fitted cover does more for service life than any material choice. Water sitting in a burner pan over winter is the single most common cause of a unit that will not light in spring.
Match lit or electronic ignition?
Match lit is a key valve and a burner. Fewer parts, no electricity, lowest price, and almost nothing to fail. You reach down, turn a key, and touch a flame to the media. For most backyards this is the right answer.
Electronic ignition buys you a button or a remote, and on all-weather systems, flame sensing that shuts off the gas if the flame goes out. The cost is real infrastructure. A typical all-weather electronic ignition system runs on 24 volts AC or 30 volts DC only, calls for 12-gauge wire, allows no more than two units daisy chained together, and requires the gas line and the low-voltage power to be run underground to each vessel.
That last requirement is the whole point. Electronic ignition is a decision you make before the patio is poured, not after. Browse ignition systems to see what a given model supports, and be aware that many electronic-ignition configurations are built to order rather than stocked.
Fire glass or lava rock?
Both work. They do different jobs.
| Lava rock | Fire glass | |
|---|---|---|
| Look | Matte, natural, hides the burner | Reflective, jewel-like, modern |
| Typical depth | 2–4 in, 3 in commonly recommended | Follow the manual; thinner layers are normal |
| Weight | 25–35 lb per cubic foot | Heavier per unit volume than lava |
| 30″ round at 3 in depth | About 55 lb | Calculate from the same volume |
| Cost at Outdoor Heat Direct | From $56 per 20 lb bag | From $59 per 10 lb bag |
A common approach is a base layer of lava rock to fill volume cheaply, topped with a thin layer of fire glass for appearance.
Where can you legally and safely put a fire pit?
Clearances are not an industry constant. They are set by the manufacturer for that specific appliance, and they vary by a factor of nearly two. Here are three real published figures.
| Source | Side clearance | Overhead clearance | Below |
|---|---|---|---|
| American Fyre Designs fire pit instructions | 36 in from unit edge | 72 in from unit top | 0 in, combustible surfaces permitted |
| General match-lit fire pit manual | 48 in from side | 96 in from hearth | Not specified |
| All-weather electronic system clearance sheet | 36 in from burner edge | 120 in from burner | Not specified |
The overhead number is the one that ends projects. A 120-inch vertical clearance is ten feet, and a great many covered patios and pergolas are not ten feet to the underside. Measure that before you fall in love with a unit.
Beyond the manual, three rules hold: gas appliances need open air and must never go in an enclosed space, combustible decking needs a non-combustible base regardless of what the manual permits over concrete, and enclosed bases holding a propane cylinder need ventilation — one manufacturer specifies 18 square inches of venting on each of two opposing sides, 36 square inches total. Our fire pit regulations overview covers the location, flooring, ceiling height and ventilation basics, but your local code and your HOA get the final word.
What are the five decisions that cost people money?
Most fire pit guides describe products. This section describes the five choices we see go wrong, all of which are made before the unit ships and none of which can be fixed without spending money twice.
1. Undersizing the gas line. American Fyre Designs specifies a minimum 1/2″ interior diameter supply pipe and states that runs longer than 20 feet may need a larger diameter. Plumbers size for the appliance in front of them. If you install a 65,000 BTU unit now and want a 140,000 BTU unit later, or you add a grill on the same branch, the line is undersized and the flame starves. Re-trenching costs $15 to $25 per linear foot plus a $100 to $300 permit, and if the patio is already in, add demolition on top. Oversize the pipe on day one; the material cost difference is trivial.
2. Choosing electronic ignition after the concrete is poured. All-weather ignition needs 24-volt power run underground to the vessel. Deciding you want a remote after the hardscape is finished means either surface-running conduit across your patio or cutting it. Make the ignition call at the design stage.
3. Not measuring the overhead clearance. People measure the patio and forget the ceiling. Published vertical clearances run from 60 to 120 inches across the brands in our clearance reference table by brand. A unit that violates the overhead figure under a pergola or a covered lanai is not a unit you can install, and a special-order fire table is rarely a simple return.
4. Buying propane with no plan for the tank. A 20 lb cylinder is about 430,000 BTU, roughly 6.6 hours at 65,000 BTU/hr.1 If the base has no cylinder door, the tank sits on your patio on a hose. Confirm the enclosure, confirm the venting, and buy a spare cylinder.
5. Buying by overall table size instead of ledge width. The specification that determines whether the table is usable is the width of the rim between the outer edge and the burner opening. Two units with identical footprints can differ by several inches of usable ledge. Ask for that dimension before you order.
A sixth, cheaper mistake: skipping the wind guard. On an exposed site it is the difference between a fire that stays lit and one that does not.
What does a gas fire pit really cost?
Active fire pits in the Outdoor Heat Direct catalog run from $629 to $24,832. Here is how the full catalog actually distributes across price bands. If you would rather start from a shortlist than a price band, our roundup of the best gas fire tables of 2026 works through twelve models with published specs and prices.
| Band | Products | What lives here |
|---|---|---|
| Under $500 | 307 | Media, covers, key valves, small components, add-on services |
| $500–$999 | 191 | Entry fire pits, larger burners, bowls |
| $1,000–$1,999 | 269 | Mid-size fire bowls and smaller fire tables |
| $2,000–$2,999 | 290 | Standard residential fire tables |
| $3,000 and up | 735 | Large tables, fire and water features, commercial scale |
Then add the things that are not on the product page. A new natural gas run to an outdoor appliance typically lands between $600 and $1,300 at $15 to $25 per linear foot, with permit fees of $100 to $300. Media adds $56 to $400 depending on vessel size. A cover, a wind guard and a spare propane cylinder are each real line items. Budget 20 to 30 percent above the appliance price for a first-time gas installation, and if you would rather spread it, we offer financing.
Which brands should you consider?
| Brand | Known for | Products |
|---|---|---|
| The Outdoor Plus | The widest configuration matrix — metals, shapes, burners, ignitions | 463 |
| American Fyre Designs | GFRC vessels with clearly published BTU and clearance data | 173 |
| Modern Flames | Electric and hybrid fireplace technology | 169 |
| Prism Hardscapes | Hand-finished concrete tables and bowls, strong color range | 135 |
| Fire by Design | Fire and water features, architectural and pool work | 119 |
| Slick Rock Concrete | Clean concrete forms, pool-side bowls and spillways | 56 |
| Firegear | Burner systems, inserts and weather covers | 14 |
If you are already leaning toward concrete, our Prism Hardscapes fire tables and fire bowls buyer’s guide goes deeper on that one manufacturer — sizes, finishes, lead times and what the concrete actually does over five years.
What do you need before installation day?
Have these settled before the crate arrives, because every one of them stalls an install:
- Fuel type confirmed and the appliance ordered in that configuration.
- Gas line run, sized with headroom, pressure tested, and delivering 7″ w.c. for natural gas or 11″ w.c. for propane at the appliance.
- Low-voltage conduit in place if the unit uses electronic ignition.
- Side and overhead clearances measured against your specific manual, not a generic figure.
- A licensed gas technician booked. Every manual we cite requires one.
- Delivery access checked — a concrete fire table can be extremely heavy and will not go through a standard gate on a hand truck.
- Media, cover and wind guard ordered at the same time so nothing waits.
Installation and final connection must be performed by a licensed professional in accordance with the National Fuel Gas Code, ANSI Z223.1/NFPA 54, and local codes.

How many BTUs do I need for a backyard fire pit?
For a typical residential patio, 60,000 to 90,000 BTU/hr is the usual range. American Fyre Designs rates its standard fire pits at 65,000 BTU on natural gas and 60,000 on propane. Larger 24-inch and 30-inch burner systems reach 150,000 to 175,000 BTU/hr, but those require a bigger gas line.
Can I put a gas fire pit under a covered patio?
Only if your roof height meets the manufacturer’s vertical clearance. Published figures range from 60 inches to 120 inches depending on the appliance — see our clearance reference table by brand. Measure to the underside of the structure first. Gas fire pits must never be installed in a fully enclosed space.
How long does a 20 lb propane tank last on a fire pit?
A 20 lb cylinder holds about 4.7 usable gallons at 91,452 BTU per gallon, so about 430,000 BTU total. On a 65,000 BTU/hr burner at full output that works out to approximately 6.6 hours. Running at a lower flame setting extends it considerably. This is our own calculation, not a manufacturer rating.
What gas pressure does a fire pit need?
Nominal supply pressure is 7 inches water column for natural gas and 11 inches water column for propane. Manufacturers publish acceptable ranges around those figures — one manual allows 3.5 to 14 inches for natural gas and 8 to 14 inches for propane. Your installer should verify pressure at the appliance.
Can I convert a natural gas fire pit to propane?
Not casually. Fuel type is a factory configuration. Conversion generally requires an orifice change and sometimes a different burner assembly, and not every model offers a conversion kit. Decide fuel before ordering. If you have already bought, contact our team with the model number before buying any parts.
How much lava rock or fire glass do I need?
Depends on vessel volume. Lava rock runs 25 to 35 pounds per cubic foot, and 2 to 4 inches of depth is typical, with 3 inches commonly recommended. A 30-inch round pit at 3 inches takes roughly 55 pounds. Critically, never exceed the media height above the burner that your manual specifies.
Is a gas fire pit safe on a wood or composite deck?
Some manuals permit zero clearance below the unit, but combustible decking is a different question from the appliance base. Use a non-combustible pad regardless, confirm side clearance from railings and furniture, and check local code and HOA rules. Composite decking in particular can soften and mark under sustained radiant heat.
What does it cost to run a gas line to a fire pit?
Running a natural gas line to an outdoor fire pit or grill typically costs $600 to $1,300, at roughly $15 to $25 per linear foot, with permit fees of $100 to $300. Complex routes under hardscape or through finished structures push the per-foot cost higher.
Do I need a wind guard?
On any exposed site, yes. A wind guard is a glass surround that keeps the flame from being blown out and stops it from being pushed sideways toward seating. It also reduces gas waste, because you are not running a higher flame just to keep it lit in a breeze.
Can I install a gas fire pit myself?
You can set the vessel, place the media and fit the cover. Final gas connection must be done by a licensed gas technician in accordance with the National Fuel Gas Code, ANSI Z223.1/NFPA 54, and local code. Every manufacturer manual we work with states this, and self-installation typically voids the warranty.
Sources and accuracy note. BTU ratings, gas supply pressures, clearances, pipe sizing and media depth limits are quoted from manufacturer installation manuals: American Fyre Designs fire pit installation instructions, a general match-lit fire pit manual, and the All Weather Electronic Ignition System install guide and accompanying clearances document. Code references are to the National Fuel Gas Code, ANSI Z223.1/NFPA 54, and ANSI Z21.97/CSA 2.41 for outdoor decorative gas appliances. Gas line installation costs are 2026 figures from published contractor cost surveys. Propane energy content (91,452 BTU per gallon, per the U.S. Energy Information Administration; about 4.7 usable gallons in a 20 lb cylinder) is from published data.
1 Our own estimate. The 6.6-hour propane runtime is calculated by Outdoor Heat Direct as 430,000 BTU (20 lb of propane × 21,548 BTU/lb) divided by 65,000 BTU/hr. It assumes continuous full output and a full cylinder. Real runtime varies with flame setting, ambient temperature and cylinder fill level.
