Choose the Right Fire Pit Burner
What Does a Burner Do?
Think of the burner as the engine of your fire pit.
It channels the gas and shapes the flame pattern. The size, shape, and BTU rating of your burner determine how much heat and visual impact you’ll get.
The burner controls the fire experience. Everything from flame height to coverage starts here.
What About BTUs?
BTUs (British Thermal Units) measure heat output.
The higher the BTUs, the stronger and taller the flame.
- Home fire pits: 60,000–125,000 BTUs
- Large/custom pits: 150,000–400,000+ BTUs
- Pro Tip: Verify with your contractor that your gas line can handle the demand
Pick the Perfect Fire Pit Pan
What Does a Fire Pit Pan Do?
The Fire Pit Pan supports the burner, holds your fire media (like fire glass or lava rock), and helps ventilate and drain the enclosure.
It’s a must-have for a clean install and long-term performance.
Types of Fire Pit Pans
Drop-In Pans
- Easy to install
- Designed to “drop in” to a cutout
- Works well with round, square, and rectangular pits
- Ideal for DIYers or standard fire pit kits
Flat Pans
- Sits flush on support brackets
- Offers more design flexibility
- Ideal for custom or built-in fire pits with no vertical lip
How to Pick the Right Drop-In Pan Size
Rule of thumb: Drop-in pans should be 1 inch smaller than the inside of your fire pit opening.
| Pan Size | Cut-Out Opening | Recommended Burner | Estimated BTUs |
|---|---|---|---|
| 19" Round Drop-In | 20" | 12" Fire Ring | 92,000 |
| 25" Round Drop-In | 26" | 18" Fire Ring | 147,000 |
| 30" Round Flat | 30+" | 18" Fire Ring | 147,000 |
| 36" Round Flat | 36+" | 18" Fire Ring | 147,000 |
| 24" x 8" Rectangle | 25" x 9" | Included H-Burner | 120,000 |
| 36" x 12" Rectangle | 37" x 13" | Included H-Burner | 165,000 |
| 48" x 14" Rectangle | 49" x 15" | Included H-Burner | 200,000 |
| 36" Linear Pan | 37" x 7" | Built-in Linear Burner | 75,000 |
| 72" Linear Pan | 73" x 7" | Built-in Linear Burner | 200,000 |
Why the Pan Matters
- Prevents burner sag
- Improves gas flow and heat distribution
- Keeps ignition system dry and secure
- Makes maintenance easier with lift-out access
Without a pan, your fire pit is vulnerable to poor performance, safety issues, and early wear.
Select the Right Ignition System
This is where things go from functional to flawless.
There are three main ways to light your fire pit and they each serve a different purpose.
Match-Lit Systems
- Manually lit with a lighter or match
- Uses a ball valve for gas control
- Most affordable and simple
- Great for: DIYers or budget-friendly installs
- Not ideal for: Windy areas or commercial use
Spark Ignition (Push-Button)
- Push-button ignites a small spark to light the gas
- Safer and more user-friendly than match-lit
- No electricity required
- Great for: Homeowners wanting a manual system with less hassle
Electronic Ignition (AWEIS)
- Fully automatic lighting
- Flame-sensing and auto re-ignition
- Works via wall switch, remote, or home automation
- Best for: High-end homes, luxury builds, and commercial spaces
- Bonus: Works in all weather—even snow or high winds
Only electronic ignition systems offer flame monitoring and automatic shut-off safety features.
If the flame goes out, the gas stops flowing automatically.

Fire Pit FAQs
Do I need a pan if I’m building into pavers or a stone base?
Yes. A pan supports the burner and improves drainage, which is critical in hardscaped installs.
Do I need ventilation in my fire pit?
Absolutely.
Every gas fire pit needs proper venting to release potential gas buildup and excessive heat.
At least 36 square inches of ventilation under the pan is recommended.
Can I install this myself?
If you’re comfortable working with gas and ignition systems, maybe.
Otherwise, we recommend a licensed installer for safety and code compliance.
The Fire Pit Buying Formula
To build a great gas fire pit, you only need three things:
- The right burner for your shape and BTU needs
- A supporting pan that keeps your system safe and efficient
- An ignition system that matches your lifestyle
Get those right, and your fire pit becomes the heart of your backyard.
