In This Guide
Mistake 1: Choosing the Wrong Burner Size
A burner that’s too small will underwhelm. One that’s too large can overpower the space, cause damage, or waste fuel.
What to Do Instead:
- Measure the internal opening of your fire pit, not the exterior
- Select a burner that’s at least 6 inches smaller than the opening
- Match the BTU output to your available gas supply
Pro Tip: Use our Fire Pit Builder Tool to match burner size and pan to your exact specs.
Mistake 2: Ignoring Ventilation
No airflow means trouble.
It leads to poor ignition, gas buildup, and burner damage over time.
Fix It With:
- At least 18 square inches of ventilation on opposite sides
- Vents placed below the burner—not hidden or blocked by framing
- Materials that won’t trap moisture or seal the base tight
Ventilation isn’t optional. It’s one of the most important safety components in your entire fire pit build.

Mistake 3: Picking the Wrong Ignition System
A match-lit system may sound simple—but it won’t cut it in windy or commercial settings.
Choosing the wrong ignition method is one of the fastest ways to frustrate your client or yourself.
The Right Ignition for the Right Project
| Ignition Type | Best For |
|---|---|
| Match Lit | Basic installs, calm climates, low-use setups |
| Spark Ignition | Push-button convenience without electrical power |
| Electronic Ignition (AWEIS) | Luxury homes, commercial spaces, code-compliant builds |
Want zero relights and full automation? AWEIS is the upgrade you’ll never regret.
Mistake 4: Using the Wrong Fire Media
Fire glass and lava rock aren’t just decorative.
They directly impact how your flame burns, how your burner performs, and how long your setup lasts.
Avoid These Common Media Errors:
- Using regular glass or river rock
- Overfilling the burner area
- Choosing the wrong type of media for the burner design
What to Use Instead:
- Fire-rated lava rock for rustic texture and heat retention
- Tempered fire glass for modern sparkle and color variety
- Mixed media blends for layered looks and even coverage
Mistake 5: No Flame Guard in Windy Areas
Flame guards aren’t just a nice touch.
In windy or open spaces, they’re a must-have.
Why Flame Guards Matter:
- They block wind from distorting or extinguishing the flame
- Keep heat directed upward and centered
- Improve flame visibility and control
- Add a clean, modern border to your fire pit
- Help prevent warping
If the flame flickers or blows sideways, your customers won’t be happy.
Mistake 6: Leaving the Fire Pit Uncovered
Debris, water, and UV exposure can destroy an unprotected fire pit over time.
That leads to clogged burners, rust, and costly part replacements.
The Fix:
- Use a stainless steel cover
- Look for built-in handles for easy removal
- Choose a cover that protects the burner system from weather and wear
Mistake 7: Mixing and Matching Random Parts
One of the most expensive mistakes is trying to piece together a system from random brands or online parts.
You’ll run into:
- Sizing issues
- Poor compatibility
- Uneven flames
- Safety problems
How to Avoid It:
- Use complete kits where all parts are pre-matched
- Ensure all fittings and ignition systems are rated to work together
- Choose a trusted manufacturer with proven performance
One supplier. One system. One smooth install.
Bonus Mistake: DIYing a Pro-Level Build
Some people can handle gas line installs.
Most shouldn’t try.
When to Call a Pro:
- You’re working with propane or running new gas lines
- Your project involves electronic ignition
- Local codes require licensed installs
Our kits are designed for pros and ready-to-go projects. But we always recommend working with a licensed contractor if you’re unsure.
