An H-burner is shaped like the letter H, producing a flame line that runs the length of the burner with a connecting bar — ideal for rectangular or linear fire pits where you want a long, even flame. A ring burneris circular, producing a uniform circle of flame — the standard choice for round fire pits and most DIY builds. A pan burner(or burner pan kit) combines either an H or ring burner with a pre-fitted stainless pan, so you have a complete drop-in assembly. The flame pattern depends on the burner inside (H or ring); the pan adds protection and simplifies installation.
The burner should be at least 6 inches smaller than the inside dimension of your fire pit opening on every side, to allow proper airflow and clearance from combustible surrounds. A 24-inch round opening fits a 12–18 inch ring burner. A 36 x 12 rectangular opening fits a 24 x 6 H-burner. Oversized burners are the most common DIY mistake — they look great on paper but the flames lick against the surround stone and discolor or crack it.
Stainless is the only material we recommend for outdoor burners. Chrome-plated steel rusts within 2–3 seasons. Cast iron rusts faster outdoors. Aluminum doesn't hold up to repeated thermal cycling. Solid 304 stainless is the minimum standard; 316 stainless is the upgrade for coastal or salt-air environments where chloride exposure is high.
Most burners ship configured for one fuel type with an orifice that can be swapped for the other. The burner body is the same; the orifice and the regulator/pressure are what change. Conversion is straightforward but should be done by someone who understands gas systems — wrong orifice plus wrong pressure equals dangerously high flame or carbon monoxide production.
Beyond the burner, you'll need: a key valve (to control gas flow), an ignition system (match-light, spark, or electronic), a flex line connecting to your gas supply, mounting hardware, fire media (glass, rock, or logs), and either a pre-built fire pit enclosure or your own built surround. Burner pan kits include some of these components; standalone burners don't. Check the product page details for each item.
A quality stainless burner installed correctly and used normally lasts 15–25 years. The most common failure mode isn't the burner itself — it's the ignition system, valves, or fittings. Replace those components every 5–10 years and the burner can outlive the fire pit it's installed in.
