A gas or propane fire pit gives you instant flame, adjustable heat and no ash to clean up. This guide walks you through the main differences between propane and natural gas models, how to match the fire pit to your space, and the safety checks that matter before your first fire.

Propane vs. Natural Gas: Know the Difference First

Most backyard gas fire pits run on either propane from a tank or natural gas from a home line. Propane models are the more common choice because they can go anywhere you can place a tank. Natural gas models need a licensed installer to connect them to your home’s supply, which makes them a permanent feature. If you rent, move often or want flexibility, propane is usually the practical pick. You can see a range of options in Fire Pit with Propane: 7 Best Models for Backyards in 2026.

Choose the Right Size and Style for Your Space

Measure your patio or deck before shopping. Leave at least 10 feet of clear space in every direction from the flame, and check that nothing overhangs the fire pit. Table-style units suit dining areas, while round bowl models work well for conversation groups. For smaller yards, a movable model can be shifted between spots.

Plan the Fuel Setup and Connections

For propane, a standard 20-pound tank is the size most owners use. Store the tank upright, outside the fire pit’s enclosure and away from heat sources. Hidden tank designs keep the cylinder out of sight but still require good ventilation. For natural gas, hire a qualified plumber or gas technician to run the line and test it for leaks. Never connect a fire pit to a gas line yourself.

Setup checklist

  1. Confirm your fire pit is rated for outdoor use and matches your fuel type.
  2. Place it on a level, non-combustible surface such as pavers, stone or concrete.
  3. Keep at least 10 feet of clearance from walls, furniture, overhanging branches and structures.
  4. Connect the regulator and hose, then check every joint with soapy water. Bubbles mean a leak.
  5. Light the unit following the manufacturer’s sequence and watch the flame for the first 10 minutes.

Safety and Maintenance Basics

Gas fire pits are safer than wood fires in many ways, but they still produce high heat. Keep children and pets back, and never leave the unit burning unattended. Store propane tanks outdoors only, and never inside a garage, shed or enclosed porch. Check hoses for cracks each season and replace any that look worn. Gas fire pit safety guidelines from the manufacturer always take priority over general tips, so read the manual before lighting.

Common mistakes to avoid

  • Placing the fire pit under a covered patio or pergola with low clearance.
  • Using a tank that is damaged, rusted or past its inspection date.
  • Skipping the leak test after reconnecting a tank.
  • Running the burner at maximum for long periods without checking for heat stress on nearby surfaces.
  • Storing spare tanks near the fire pit or indoors.
  • Propane regulator and hose kit: A correctly rated regulator keeps gas flow steady and reduces the risk of leaks at the connection. View on Amazon
  • Fire pit cover: A fitted cover protects the burner and burner pan from rain and debris when the unit is off. View on Amazon
  • Leak detection solution: A soapy-water spray is the simplest way to check every connection before use. View on Amazon

FAQ

Can I use a gas or propane fire pit on a wooden deck?

Some manufacturers allow it when the unit sits on a fire-resistant base and meets required clearances. Check the product manual and local fire codes first, and consider a heat-protective mat under the base.

How long does a propane tank last in a fire pit?

Run time depends on burner output and how long you use the fire pit each session. Most owners check the tank level with a gauge or by weighing it before each use.

Do gas fire pits need a permit?

Natural gas installations usually require a permit and inspection. Propane units that connect to a portable tank generally do not, but local rules vary, so confirm with your city or county building department.

Conclusion

Choosing a gas or propane fire pit comes down to fuel type, space and safe placement. Match the unit to your yard, set it up with proper clearances and leak checks, and keep up with basic maintenance. Consult a licensed gas professional for any natural gas installation.
