How Do You Start a Fire Pit? What Slips Back, and How Fast
Starting a fire pit begins before anything is lit. Confirm the burn ban for the address on the day of use, identify whether the pit burns wood or gas, and check wind against the local limit, which runs from 7 mph in Neenah, Wisconsin, to 15 mph in Edina, Minnesota. Place the pit at the clearance printed in its own manual. For wood, burn only seasoned pieces below 20 percent moisture content, stack tinder under kindling under split logs, and light it with a match or a commercial fire starter rather than any accelerant. For gas, leak-test the fittings with soapy water, hold the ignition for 15 seconds, and wait five minutes before a second attempt if the burner does not catch. Section 307.5 of the 2021 International Fire Code requires a 4-A rated extinguisher or an approved substitute such as sand or a garden hose on hand, plus constant attendance until the fire is out.
The teepee demonstration that circulates online covers about two minutes of an evening that runs four hours and keeps going after everyone goes inside. What fails is what comes back: wind that drops at dusk and returns at ten, ash that reads cool on top and holds live coals for days.
Should this fire be lit tonight?
Burn restrictions are local and move with conditions, so they get checked on the day of use rather than at the start of the season. Texas A&M Forest Service compiles a statewide burn ban map by county because authority there sits with each county judge or commissioners court under Local Government Code 352.081, which lets neighboring counties hold opposite answers on the same night. Edina, Minnesota, runs a Recreational Fire Hotline residents are told to call before lighting. Palmer Lake Fire Rescue in Colorado issues campfire permits valid only for the stated date, requires the request by 4 p.m. that day, and states that its permit does not override a burn ban already in force.
Wind is the second gate, and the published limits disagree. The Neenah-Menasha ordinance in Wisconsin prohibits a recreational fire "any time when the wind speed exceeds seven miles per hour." Minneapolis allows fires only below 10 miles per hour. Portage, Michigan, sets the same ceiling and adds the obligation most homeowners miss: extinguish the fire if wind rises past 10 mph after it is lit. Edina, Minnesota, allows fires only below 15 mph. A National Weather Service Red Flag Warning overrides any favorable wind reading.
A gas fire pit and a wood fire pit are not the same appliance
They look alike on a patio and are governed by different documents. A wood pit burns solid fuel the owner supplies and controls. A gas pit is a certified appliance with a regulator, a fuel line and a shutoff valve, and the manual for one gas fire table certified to ANS Z21.97/CSA 2.41-2017 puts it directly: "DO NOT burn solid fuels in this appliance." The same manual rules out a common patio placement, warning the appliance "is not for use on wood decks or other flammable surface."
The split runs through every step. A wood pit needs dry fuel, a spark screen and an ash plan; a gas pit needs a leak test and a correct flame color, and produces no ash. A wood pit is shut down with water and stirring; a gas pit is shut down by turning the knob to OFF and closing the cylinder valve, after which the metal stays hot with no flame to signal it. A wood fire that will not catch is a fuel problem. A gas burner that will not catch is a gas problem, and the manual's answer is to stop and wait rather than keep pressing the igniter. Even the endpoint differs: the gas table draws 30,000 BTU/hr from a 20 lb cylinder and ends when the tank ends, while a Solo Stove Bonfire 2.0 burns 16-inch logs in a 19.5-inch bowl and ends when the owner stops feeding it.
The clearance number is not on the internet, it is on the pit
No single distance approves every site. The figures below come from code, municipal ordinance and two owner's manuals, ranging from 24 inches to 25 feet.
| Source | Clearance | Size cap | Wind | |---|---|---|---| | 2021 IFC 307.4.2, recreational fires | 25 ft | — | — | | 2021 IFC 307.4.3, portable outdoor fireplaces | 15 ft; exempt at one- and two-family dwellings | — | — | | Minneapolis | 25 ft from buildings | under 3 ft wide, 2 ft high | under 10 mph | | Neenah-Menasha, Wisconsin | 10 ft from any building, fence or combustible | 30 in diameter, flames under 2 ft | over 7 mph banned | | Solo Stove Bonfire 2.0 manual | 6 ft from vertical surfaces; 15 ft overhead | 19.5 in bowl | warns against windy conditions | | Gas fire table manual, ANS Z21.97/CSA 2.41-2017 | 24 in sides, 72 in top | — | — |
That gas manual contradicts itself. Its specification table lists 24 inches at the sides and 72 inches at the top; item 20 of the same safety list reads, "Never use this appliance closer than 10 feet from anything flammable, including houses or overhead tree branches." Until the manufacturer resolves it, the larger figure is the one that fails safe.
IFC 307.4.3 sets 15 feet for portable outdoor fireplaces, then exempts those used at one- and two-family dwellings, which describes most backyard pits. The exemption removes the code distance without removing the physics, and the manufacturer's number stands either way.
How dry the wood has to be, and why the bag can be wrong
EPA Burn Wise states that wood burns best below 20 percent moisture content, advises seasoning at least six months, and recommends a moisture meter before burning. University of Tennessee Extension publication W179 sets the same threshold: wet wood burns incompletely, and heat that should reach the patio goes into evaporating water.
The label on a bundle is not a measurement. Adam Taylor, Assistant Professor at the Tennessee Forest Products Center, bought bags of firewood from a Knoxville supermarket and measured every piece by the oven-dry method. All of it was oak, all of it was labeled "Seasoned Firewood," and all of it was too wet. The average came to 66 percent moisture, against a green figure for oak of 75 to 80 percent. Taylor's advice is to buy and stack early: "there is no danger in over-seasoning wood — drier is better."
Method matters when quoting any threshold. A meter pressed to a weathered outer face reads the driest part of the piece. Taylor calls the oven-dry method the reliable test; for a meter, split a log and read the fresh inner face.
Sources part company on what else may go in. EPA Burn Wise prohibits "plywood, particle board, or any wood with glue on or in it," along with coated, painted and pressure-treated wood. W179 lists "clean lumber or plywood scraps" among acceptable fuels, while agreeing painted and treated wood must never be burned. Local rules run stricter than both: Minneapolis permits natural cut wood only, Edina wood from trees, small branches or charcoal.
Lighting a wood fire without an accelerant
Every manual consulted for this article bans liquid fuel at ignition. The gas fire table manual instructs: "Never use gasoline, kerosene, or any other liquid fuel to start a fire." Solo Stove rules out gasoline, kerosene, diesel, lighter fluid and alcohol. A weak fire is an air-and-moisture problem, and accelerant addresses neither while adding flash and unpredictable spread.
- Clear the area to bare soil, gravel or another non-combustible surface, and set the pit level.
- Place a handful of tinder in the center: dry twigs, wood shavings, or a paraffin-and-sawdust fire starter, the practical answer when there is no kindling on hand.
- Lean split kindling over the tinder, keeping gaps for airflow rather than packing it tight.
- Add two or three split logs, seasoned under 20 percent moisture, once the kindling burns steadily.
- Fit the spark screen; Solo Stove sells a shield accessory for the same purpose.
- Feed the fire in single pieces, keeping flame height inside the limit the local ordinance sets.
How to turn on a gas fire pit
The leak test comes first, before ignition, and again every time the cylinder is reconnected. The manual specifies 2 to 3 ounces of solution mixed from one part liquid dishwashing detergent and three parts water, with the control knob confirmed OFF. Apply several drops where the cylinder attaches to the regulator, then at the gas valve and inlet tube, and watch for bubbles. Bubbles mean disconnect, reconnect, and test again; bubbles that persist after several attempts point to a defective valve or part. A flame is never used to check for leaks, and the test happens outdoors.
Ignition follows a fixed sequence. Turn the control knob to OFF, then to ON/MIN, push it all the way in and hold, and press the ignition button for up to 15 seconds. If the burner has not lit, release the knob and wait a full five minutes before trying again, which lets unburned gas disperse. A correct flame is blue with straight yellow tops; excessive yellow is a signal to turn the pit off.
What has to be within reach while it burns
IFC 307.5 requires constant attendance until the fire is extinguished, plus at least one portable extinguisher rated 4-A or approved alternatives including dirt, sand, a water barrel or a garden hose. Jurisdictions build on that floor with different volumes. Washington Administrative Code 332-24-211 requires a serviceable shovel and a minimum of five gallons of water in the immediate vicinity, with a charged hose accepted instead. Palmer Lake Fire Rescue asks for a charged hose line, 10 gallons of water, or a 10 lb extinguisher rated at least 4A, within 25 feet at all times. Portage, Minneapolis and Edina each require the fire to be attended by a person 18 or older until it is out.
Putting it out, and the part that comes back
A steam cloud is not proof of extinguishment. The sequence that works is water, then stirring with a shovel to expose buried coals, then more water, repeated until stirring produces no hiss and no steam. Washington's rule pairs the five gallons with a shovel for that reason. Dousing a hot pit and walking away leaves the fuel underneath untouched.
Then the ash has to cool, and published guidance splits here. The Cottleville Fire Protection District in Missouri advises waiting two to three days, letting ashes cool in place before removal. Fire Chief JP Kennedy of Whately, Massachusetts, puts the window far longer. After a January 2026 garage fire in his town, Kennedy said: "We want homeowners to be aware that ashes from wood stoves and fireplaces can remain hot for over a week. They should always be disposed of and stored away from anything combustible." The homeowner had left those ashes outdoors four days before moving them to a plastic tote. "Even after four days, the ashes were still hot," Kennedy said.
Both districts agree on the container: metal, lidded, stored outdoors away from anything combustible, never a plastic bin or bag. A gas pit makes no ash and still holds heat; its manual warns the appliance is hot during and after use, and requires ample cooling before it is moved.
