How to Upgrade an Outdated Fireplace for a Cozier, Better Winter
A Simple, Step-by-Step Guide from American Fire Products
If you have an older gas fireplace, you’re not alone.
A lot of gas fireplaces still “work,” but don’t really perform, especially in winter.
The flame looks small.
The room stays chilly.
And the fireplace that should be the heart of the home feels… underwhelming.
Here’s the good news.
Most outdated gas fireplaces don’t need to be replaced.
They just need to be rebuilt the right way.
At American Fire Products, we help homeowners upgrade fireplaces every day. This guide walks you through exactly how to do it—step by step—using the same approach we recommend to contractors and serious DIYers.
No full remodel.
No guesswork.
Just smarter parts and better performance.
Why Old Fireplaces Struggle in Winter
Winter has a way of exposing problems.
Cold air affects gas flow.
Homes are sealed tighter.
Fireplaces run longer and harder.
That’s when outdated setups start to show signs like:
- Weak or uneven flames
- Heat that stays trapped near the glass
- Dark spots or dead zones in the fire
- A fireplace that looks dated instead of inviting
Most people assume this is just “how fireplaces are.”
It’s not.
In most cases, the problem comes down to two things:
Fix those—and everything changes.
Step 1: Start With the Burner (This Is the Foundation)
If a fireplace doesn’t perform well in winter, the burner is usually the reason.
The burner controls:
- Where gas flows
- How evenly flames spread
- How strong the fire looks and feels
Many older fireplaces use basic burners that push gas in a straight line. That design works—but only just.
Why We Recommend H-Burners
At American Fire Products, we design and sell H-Burners because they solve the most common fireplace performance issues.
An H-Burner is shaped like the letter “H.”
That shape spreads gas evenly across the entire firebox instead of focusing it in one spot.
Why That Matters in Cold Weather
H-Burners:
- Create fuller flames from end to end
- Reduce cold or dead spots
- Support fire media evenly
- Hold up better during long winter burn times
Think of the burner like the engine.
You can change how a fireplace looks all day long, but if the burner isn’t right, the fire will never feel right.
Find the right burner for your fireplace
Quick note: Always follow your fireplace manufacturer guidelines and local codes. If you’re unsure about gas connections or setup, work with a licensed professional. A great-looking fireplace should also be a safe one.
Step 2: Decide the Look and Feel You Want
Once the burner is handled, it’s time to choose fire media.
This is where style meets performance.
There are 2 popular directions for indoor fireplaces:
Both work well in winter when installed correctly. The right choice depends on the look you want and how you use your fireplace.
Option 1: Using Fire Glass for a Modern Winter Upgrade
Fire glass isn’t just for outdoor fire pits.
More homeowners are choosing fireplace fire glass because it performs extremely well in winter.
Why Fire Glass Works So Well in Cold Months
Fire Glass:
- Reflects heat back into the room
- Reflects light, making flames look brighter
- Doesn’t burn away or degrade
- Holds up during long burn times
At American Fire Products, our quarter-inch premium fire glass is designed specifically for natural gas fireplace use.
The size matters.
Quarter-inch fire glass:
- Allows proper airflow
- Covers the burner evenly
- Creates consistent flame patterns
- Prevents flame choking
How to Install Fire Glass Correctly
This part is important.
Do:
- Spread fire glass evenly across the burner
- Must sure to fully cover burner by 1-2”
- Keep the layer loose and natural
Don’t:
- Overfill the firebox
- Block airflow
Fire glass should sit on the flame—not fight it.

Option 2: Using Lite Stone Balls for a Balanced, Natural Fireplace Look
If you love the warmth of a traditional fire but want something different from logs or fire glass, Lite Stone Balls are an excellent choice.
These stone balls blend classic aesthetics with practical performance—and they work especially well in winter fireplaces when set up correctly.
What Lite Stone Balls Bring to the Fireplace
Lite Stone Balls:
- Provide a natural, textured look
- Allow flames to rise through and around them
- Look great with both traditional and modern designs
- Work well with balanced flame systems like an H-Burner
- Sits perfectly on a base layer of Lava Rock
Unlike logs that aim for a wood-fire aesthetic, or fire glass that shines and reflects light, Lite Stone Balls create a textural, organic flame environment that feels grounded and warm.
Why Lite Stone Balls Perform Well in Winter
Lite Stone Balls are designed to complement a strong burner like an H-Burner. When used together, they help:
- Diffuse flame paths for a fuller, more natural pattern
- Maintain consistent heat distribution
- Allow flames to weave through the material, making the fire look deeper
- Avoid the “flat” appearance that can happen with media that sits too closely packed
How to Install Lite Stone Balls Correctly
Proper installation makes all the difference. Here’s how to do it the right way:
Do:
- Spread lava rock evenly over the burner (base layer)
- Use enough lava rock to cover the burner
- Add Lite Stone Balls on top of the lava rock
- Leave small gaps between balls so flames can rise naturally
Don’t:
- Pack the balls tightly together
- Pile them too high above the burner ports
- Block airflow with uneven placement
The goal is a balanced media layer that lets the flame breathe and perform.
What Your Fireplace Will Look Like
When installed correctly over a quality burner:
- Flames will weave through the Lite Stone Balls
- The fire will appear deep and dynamic, not flat
- Your fireplace will have a “designed” look—not just a functional one
Lite Stone Balls are a great middle ground. They give fireplaces character and depth while still performing reliably in cold weather.

Step 3: Understand This One Rule (Most People Miss It)
Here’s the biggest mistake we see.
People upgrade one part and expect everything to improve.
A strong burner with the wrong media won’t perform well.
Fire glass on a weak burner won’t either.
Your fireplace is a system.
That’s why American Fire Products designs burners and fire media to work together.
When they’re matched correctly, you get:
- Strong flames across the entire fireplace
- Better heat distribution
- Cleaner, more consistent burns
- A fireplace that looks intentional—not patched together
Step 4: Light the Fireplace and Fine-Tune It
Once everything is installed, turn the fireplace on and watch closely.
You should see:
- Flames across the full burner
- Even height from side to side
- No dark or dead spots
- Clean, bright fire
If something looks off:
- Adjust the media slightly
- Improve spacing
- Remove excess material
Small changes make a big difference.
Why This Upgrade Works Better Than a Remodel
Many homeowners assume the only way to modernize a fireplace is to replace it.
That’s rarely true.
In most cases, upgrading:
- The burner
- The fire media
- Or both
Delivers the biggest improvement—for a fraction of the cost.
That’s why contractors and homeowners focus on these components first.
They’re the parts that actually change how a fireplace performs.
