Fire Pit Installation in Orange County, California
5 min read
A fire pit is the least expensive way to make a backyard feel finished, and it is also the element most often built without the two details that actually matter: burner sizing relative to the opening, and ventilation of the enclosure. Get the first wrong and you have either a whisper of flame lost in a large bowl or a fire that scorches the surrounding stone. Get the second wrong and you have a sealed masonry box slowly collecting gas. Benitez Contractors builds fire pits across Orange County in stone, block, concrete and steel, with the burner sized to the opening, the enclosure vented per code, and the gas line permitted and pressure tested.

How Is a Gas Fire Pit Burner Sized?
By the size of the burner opening and the fuel supply, and the two common approaches are a ring burner or a rectangular pan burner. A general guideline is that the burner should be roughly six to twelve inches smaller than the interior opening on each side, which leaves room for media and keeps flame away from the stone edge. BTU output follows: a 24 inch ring typically runs 60,000 to 90,000 BTU, a 36 inch ring 90,000 to 150,000, and larger linear burners more. That output has to be delivered, which means the gas line is sized for the burner load plus anything else on the branch, and it is common for a fire pit added to an existing outdoor kitchen line to push the total demand past what the existing pipe supports. Air mixers matter with propane, where the burner needs a mixing device to combust cleanly and avoid the sooty yellow flame that blackens stone and glass.
- Burner smaller than the opening: Six to twelve inches of clearance on each side between burner and enclosure interior keeps flame off the stone.
- BTU matched to diameter: Roughly 60,000 to 90,000 BTU for a 24 inch ring and 90,000 to 150,000 for a 36 inch, delivered by a properly sized line.
- Air mixer for propane: Propane burners need an air mixer to combust cleanly, without which flames run yellow and soot the media and surround.
- Accessible key valve: A shutoff key valve located outside the fire pit itself, within reach but far enough away to operate safely.
Why Does the Enclosure Need Ventilation?
Because gas that escapes inside a sealed masonry box has nowhere to go. Both fuels require enclosure ventilation, and the requirement is more urgent with propane, which is heavier than air and sinks to the bottom of a cavity where it can accumulate to an explosive concentration. Manufacturers of burner systems publish minimum free vent area, commonly expressed in square inches, and typically require vents on at least two opposing sides, low for propane and both low and high for natural gas. Vents are installed as stainless or brass louvers with insect screening so they stay open rather than being blocked by debris or a spider nest. The burner pan itself should also be drilled or fitted with drainage so rain that gets past the media does not fill the pan and sit in the burner ports, which is the most common cause of a fire pit that will not light after a wet week.
Which Fire Media Should Be Used?
Only media rated for the purpose, because ordinary rock traps moisture and can spall violently when heated. Lava rock is the traditional and least expensive choice, porous, forgiving, good at diffusing flame, and it dulls over time. Fire glass gives a modern jewel like look, comes in a wide color range, radiates heat well and stays clean, but it shows soot immediately if the burner is running rich and it costs several times more than lava rock. Ceramic logs give a wood fire appearance with gas convenience and suit rustic and traditional designs. Media depth matters: too much buried over the burner ports restricts gas flow and produces uneven flame, and manufacturers typically specify a maximum depth over the burner, usually a couple of inches. A layer of lava rock beneath a top dressing of glass is a practical compromise that reduces the glass volume required.
Where Can a Fire Pit Safely Go?
Not under a patio cover, not close to a structure, and not beneath tree canopy. As a practical minimum we place fire pits at least ten feet from any structure, fence or overhanging combustible material, and further where a wood burning pit is involved. A gas fire pit under a solid patio cover requires substantial vertical clearance and, in most cases, is simply not appropriate no matter how tempting the covered space is. Seating clearance is the other dimension: allow three feet from the outer edge of the fire pit to the front of seating so people can pass behind seated guests and so radiant heat is comfortable rather than punishing. Wind matters in Orange County: a fire pit in a wind exposed corner will blow out repeatedly, and a wind guard, a partial screen wall or simply relocating to a sheltered part of the yard is the fix.
Scope
What's Included
Everything below is written into your scope of work before construction starts. Anything outside it requires a signed change order first.
- Design, sizing and placement: Shape, diameter, height and location set for seating comfort, wind shelter and safe clearance to structures and canopy.
- Foundation and enclosure construction: Compacted base or thickened slab, then block or steel stud and cement board enclosure built to the burner manufacturer dimensions.
- Permitted gas line and key valve: Branch sized for the burner load and anything else on the line, run in rigid pipe, with an accessible shutoff, pressure tested and inspected.
- Burner, pan and ignition: Stainless burner and pan sized to the opening, with match lit, push button spark or electronic ignition per your selection.
- Enclosure ventilation: Screened vents on opposing sides sized to the manufacturer free area requirement and positioned for the fuel type.
- Veneer, cap and media: Stone, tile or stucco finish over lath and mortar, a stone or concrete cap, rated media installed to the specified depth, and a burner cover.
How it works
Our Process
Every project follows the same structured sequence, so you always know what happens next and who to call.
Design and placement
3 to 10 daysDiameter, height and location selected against seating layout, wind exposure and clearance to structures, with the outline mocked in the yard.
Gas assessment and permit
1 to 4 weeksBurner BTU added to existing connected load, developed length measured from the meter, pipe sized and the gas permit filed with your city.
Gas trench and pressure test
2 to 4 daysRigid pipe trenched to the fire pit location with a key valve set outside the enclosure, then air pressure tested and witnessed at inspection.
Enclosure construction
3 to 6 daysBase prepared, block or steel stud enclosure built to burner dimensions, vents installed on opposing sides, and the pan support set level.
Veneer, burner and commissioning
3 to 6 daysVeneer and cap installed, burner and pan set, media placed to the specified depth, then lit, flame quality verified and operation demonstrated.
Budget
What does it cost?
Real ranges, stated up front. Your written proposal replaces these estimates with fixed numbers for your actual scope.
Typical range
$2,500 to $18,000
per project
Estimated 2026 Orange County pricing. A simple block and veneer wood burning pit starts near $2,500 to $4,500. A 42 inch gas fire pit with stone veneer, electronic ignition, fire glass and a permitted gas run from the meter typically runs $7,500 to $13,000, and larger linear designs with seat walls reach $18,000. Planning estimate only.
Typical timeline: One to two weeks of on site construction. Where a new permitted gas run is required, plan on three to six weeks total including permit issuance, trenching, pressure test and inspection before the burner is set and commissioned.
What moves the price
- Fuel type: A wood burning pit needs no gas work at all. A gas pit requires a sized, permitted, pressure tested line, which is often half the project cost.
- Distance from the gas meter: Trenching 15 feet across open dirt is inexpensive. Running 70 feet under a finished paver patio requires lifting, sleeving and resetting the field.
- Ignition system: Match lit is the least expensive, push button spark ignition costs more, and electronic ignition with a safety shutoff and remote is the highest.
- Size and geometry: A 36 inch round pit is efficient. Large rectangular and linear designs need bigger burners, more veneer, larger caps and more media volume.
- Veneer and cap material: Stucco with a concrete cap is the value option. Full stone veneer with a cut natural stone or porcelain cap costs several times more.
- Media selection: Lava rock is inexpensive. Fire glass and ceramic log sets cost substantially more, and larger openings require more media volume.
Answers
Frequently asked questions
How much does a fire pit cost in Orange County?
Estimate $2,500 to $18,000 in 2026. A simple block and veneer wood burning pit runs $2,500 to $4,500. A 42 inch gas fire pit with stone veneer, electronic ignition, fire glass and a permitted gas line typically runs $7,500 to $13,000 depending on the distance from the meter.
Do I need a permit for a fire pit?
The gas line does require a permit and a pressure test in every Orange County jurisdiction, and that is the majority of the work on a gas fire pit. A wood burning masonry pit is often exempt as a landscape feature, though HOA approval is commonly required and some associations prohibit wood entirely.
How big should a fire pit burner be?
Roughly six to twelve inches smaller than the interior opening on each side, so flame stays away from the stone edge. A 24 inch ring usually runs 60,000 to 90,000 BTU and a 36 inch ring 90,000 to 150,000, and the gas line must be sized to deliver that output.
Why does a gas fire pit enclosure need vents?
Because escaped gas in a sealed masonry box accumulates. Propane is heavier than air and pools at the bottom, which is why manufacturers require screened vents on at least two opposing sides sized to a specified free area. Natural gas rises, so vent placement differs, but ventilation is required for both.
What can I put in a fire pit as media?
Only rated fire media: lava rock, tempered fire glass or ceramic log sets. Ordinary landscape rock traps moisture and can spall or fracture violently when heated. Media depth over the burner should not exceed the manufacturer maximum, usually a couple of inches, or flame becomes uneven.
How far should a fire pit be from the house?
At least ten feet from any structure, fence or overhanging combustible material as a practical minimum, and more for wood burning. Fire pits should not be installed under solid patio covers. Allow about three feet from the fire pit edge to the front of seating for comfort and circulation.
Can I convert a wood burning fire pit to gas?
Usually yes, if the enclosure interior dimension suits an available burner and the structure can accept the required ventilation openings. The work involves cutting vents, running and permitting a properly sized gas line with a key valve, and setting a pan and burner sized to the existing opening.
