7 Fire Pit Mistakes That Could Ruin Your Build (And How to Avoid Them)

Don’t Just Build a Fire Pit—Build It Right

Every fire pit starts with good intentions. A cozy flame. A clean install. A showpiece your guests will talk about.

But for thousands of homeowners and pros, that vision gets derailed by simple mistakes—mistakes that cause poor performance, code issues, costly repairs, or worse.

At American Fire Products, we’ve worked with everyone from DIYers to luxury builders. And we see the same fire pit problems come up again and again.

This guide breaks down the top fire pit mistakes, how to avoid them, and what to do if you’ve already made them.

If you’re building or selling fire features, this is the article to bookmark.


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 (don’t guess—verify line size and pressure)

Pro Tip: Use our Fire Pit Builder Tool to match burner size & 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

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. And choosing the wrong ignition method is one of the fastest ways to frustrate your client or yourself.

The Right Ignition for the Right Project:

Match Lit – Basic installs, calm climates, low-use setups

Spark Ignition – Homeowners who want push-button convenience without 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 (it can pop or shatter)

❌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

Compare Media Options


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

✔ Helps prevent warping

If the flame flickers or blows sideways, your customers won’t be happy.

Mistake 6: Leaving the Fire Pit Uncovered

Debris, water, UV exposure—uncovered fire pits take a beating. And 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 fits on the outside of your burner to protect components from weather and wear

Find the Right Cover


Mistake 7: Mixing and Matching Random Parts

One of the most expensive mistakes is trying to piece together a system from different brands or online parts. You’ll run into sizing issues, poor compatibility, uneven flames, and safety problems.

How to Avoid It:

✔ Use complete kits where all parts are pre-matched

✔ Ensure all fittings, pans, and ignition components 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.
