Assembling a Patio Fire Pit or Fire Pit Table the Right Way
You bought a patio fire pit or fire pit table that arrived in pieces, and it needs to be put together correctly, including the burner and fuel connection if it's gas.
Patio fire pits come as wood-burning bowls or as gas units with a burner, a control valve, and a hidden tank or supply line. Assembly involves building the frame or enclosure, mounting the burner pan, and on gas models making the fuel connection and checking it for leaks. Because a fire feature involves an open flame and, on gas units, a pressurized fuel line, the connections must be made carefully per the manual and leak-tested before the first burn.
How the job is done
- 1
Sort parts and read the manual
All panels, hardware, the burner, and any gas components are laid out and checked against the instructions, since fire pits vary widely between wood and gas designs.
- 2
Build the base or enclosure
The frame, bowl, or table enclosure is assembled following the sequence, with fasteners snugged so the structure is stable and square before the burner goes in.
- 3
Mount the burner and pan
On gas models the burner ring and pan are positioned and secured according to the manual so the flame pattern and clearances are correct.
- 4
Make and leak-test the gas connection
The fuel line or tank is connected per the instructions, and the joints are checked for leaks with a soapy water solution before any attempt to light the unit.
- 5
Add media and do a test burn
Lava rock or fire glass is arranged as the manual specifies, and the unit is lit briefly to confirm even ignition and a steady flame in a safe outdoor spot.
- 6
Confirm placement and clearances
The finished pit is set on a stable, non-combustible surface with clearance from walls, railings, and overhangs so it can be used safely.
What a pro checks
- Distinguishes wood-burning from gas designs, since assembly differs significantly
- Builds the base square and stable before mounting the burner
- Follows the manual for burner placement so the flame pattern is correct
- Leak-tests gas connections with soapy water before the first lighting
- Arranges lava rock or fire glass as specified, not piled over the burner ports
- Places the pit on a stable, non-combustible surface away from overhangs
- Confirms clearances from walls, railings, and anything that can catch fire

Frequently asked questions
Do gas fire pits need a leak test before use?
Yes. Any gas connection should be checked for leaks, commonly with a soapy water solution that bubbles at a leak, before the unit is ever lit. This is a basic safety step that should never be skipped.
Can I put any rock in a gas fire pit?
No. Gas units call for media rated for fire pits, such as lava rock or tempered fire glass, arranged so it doesn't block the burner ports. Ordinary landscaping or river rock can trap moisture and crack or pop when heated.
Where is it safe to place a fire pit?
On a stable, level, non-combustible surface with generous clearance from walls, railings, furniture, and anything overhead. Manufacturers list minimum clearances, and an open sky above the unit is important for safe use.
