- Drainage and maintenance access
For many custom gas fire pit builds, using a burner pan can create a more finished and professional result.
How to Size a Fire Pit Burner
Burner sizing depends on your enclosure dimensions, desired flame coverage, and fuel supply.
As a general rule, the burner should not touch the inside walls of the fire pit. Leaving proper clearance helps maintain airflow, improves flame performance, and keeps heat from concentrating too closely against the enclosure.
When sizing a burner, consider:
- Inside dimensions of the fire pit
- Burner shape
- Desired flame coverage
- Gas supply capacity
- Media depth
- Ignition system compatibility

Fire Pit Burner FAQs
Which burner creates the biggest flame?
CROSSFIRE burners are known for producing tall, dramatic flames, while larger H-burners and rectangular burners can provide strong flame coverage in oversized fire pits. The CROSSFIRE design in particular is popular for creating a bold, eye-catching centerpiece flame. Choosing the right burner style often comes down to whether you want height and drama or broader, more even flame coverage.
Are brass burners worth it?
Brass burners can be worth the investment for premium fire pits, coastal areas, humid climates, and long-term outdoor installations because they offer excellent corrosion resistance. This makes them a strong choice for locations near saltwater or areas with frequent rain and humidity exposure. While brass burners typically cost more upfront, their extended lifespan can offset the added expense over time.
What size burner do I need?
The right burner size depends on the inside dimensions of your fire pit, desired flame coverage, fuel supply, and ignition system. The burner should leave clearance from the fire pit walls. A common guideline is to choose a burner at least 6 inches smaller than your enclosure's interior dimensions. Always reference manufacturer sizing charts to confirm the best fit for your specific project.
Do burner shapes matter?
Yes, burner shape affects flame distribution, appearance, and how well the burner fits the fire pit enclosure. Round and square burners tend to produce a more uniform flame pattern, while linear or custom shapes can create a more dramatic, architectural look. Selecting a shape that matches your enclosure design helps ensure both proper fit and the intended visual effect.
