Gas Logs for Double Sided Fireplace
Everything you need to know about choosing, sizing, and installing gas logs for your see-through fireplace
View Recommended SetsWhy Gas Logs for a Double Sided Fireplace? A double sided fireplace is a stunning architectural feature that connects two rooms. Choosing the right gas logs ensures both sides enjoy a realistic, consistent flame without the mess of wood. This guide covers vented vs ventless options, sizing, safety, and top recommendations.
Understanding Double Sided Fireplace Gas Logs
A double sided fireplace, also known as a see-through fireplace, is designed to be enjoyed from two adjacent spaces. Unlike traditional single-sided fireplaces, the log set must be visible and realistic from both sides. This unique requirement affects everything from log arrangement to burner design. Gas logs are an excellent choice for these fireplaces because they offer instant ignition, consistent flames, and no ash or creosote. However, not all gas log sets are suitable for see-through applications. You'll need a set specifically designed for double sided fireplaces, which typically features a symmetrical log arrangement and a burner that distributes flames evenly across the entire width. Understanding the difference between ventless fireplace logs and vented fireplace logs is your first step. Ventless logs burn cleaner and don't require a chimney, but they produce more moisture. Vented logs require a flue but offer a more realistic flame and are often preferred for larger fireplaces. For a double sided fireplace, ventless sets are often more practical because they don't require a complex venting system that must serve two rooms. However, if your fireplace already has a chimney, vented logs can be a great choice. You can explore a wide range of logs for gas fireplace options to understand the broader market before narrowing down to double sided models.
Vented vs Ventless Gas Logs for Double Sided Fireplaces
The choice between vented and ventless gas logs is the most important decision you'll make. Each has distinct advantages and limitations, especially when applied to a double sided fireplace.
| Feature | Ventless Gas Logs | Vented Gas Logs |
|---|---|---|
| Venting Required | No chimney or flue needed | Requires a working chimney or vent |
| Efficiency | High – almost all heat stays in the room | Lower – some heat escapes up the chimney |
| Flame Realism | Good, but often slightly less realistic | Excellent – looks more like a real wood fire |
| Moisture Production | Produces water vapor; may need ventilation | Minimal moisture; vented outside |
| Installation Complexity | Simple – no venting work | Moderate – requires chimney inspection |
| Best For | Homes without a chimney, apartments, smaller rooms | Homes with an existing chimney, larger spaces |
For a double sided fireplace, ventless logs are often the preferred choice because they don't require a chimney that serves both sides. However, if your double sided fireplace is a traditional masonry unit with a chimney, vented logs can provide a more authentic look. It's crucial to check local building codes, as some areas restrict ventless logs. You can also consider ventless fireplace logs with remote for added convenience. If you're unsure about your fireplace's venting capabilities, consult a professional. For more on installation, see our guide on gas fireplace installation requirements.
Sizing and Placement for Double Sided Fireplaces
One of the biggest mistakes homeowners make is buying a gas log set that is too small or too large for their double sided fireplace. Because the fireplace is open on two sides, the log set must be proportional to the entire firebox, not just one side. Measure the width and depth of your firebox accurately. Most manufacturers provide guidelines based on the width of the firebox. As a rule of thumb, the log set should occupy about 70-80% of the firebox width. For example, if your firebox is 36 inches wide, look for a 24 to 30-inch log set. You should also consider the height. The logs should not block the flames or create excessive soot. For double sided fireplaces, look for sets that are specifically labeled as "see-through" or "double sided." These sets have a symmetrical arrangement that looks good from both sides. You can also explore ceramic fireplace logs which are durable and realistic. If you want to add decorative elements, consider decorative birch logs for fireplace or artificial birch logs for fireplace to enhance the look. Always follow the manufacturer's sizing chart, and if in doubt, consult a hearth professional. For more on sizing, see our how to size a fireplace guide.
Key Features to Look For
When shopping for gas logs for a double sided fireplace, keep these features in mind:
- Symmetrical Design: The log arrangement must look natural from both sides. Look for sets that are specifically designed for see-through fireplaces.
- Burner Type: A dual-burner system or a burner that runs the full width of the firebox ensures even flames on both sides.
- Remote Control: Many modern sets come with a remote for easy on/off and flame height adjustment. See fireplace remote control replacement if you need a replacement.
- Safety Features: An Oxygen Depletion Sensor (ODS) is essential for ventless logs. It automatically shuts off the gas if oxygen levels drop.
- Material: Ceramic logs are more durable and realistic than refractory cement. They also retain heat better.
- BTU Output: Match the BTU output to your room size. For double sided fireplaces, you may need a higher BTU output to heat both rooms. Our fireplace heating capacity BTU guide can help.
- Thermostat: A built-in thermostat or a fireplace thermostat guide can help you maintain a comfortable temperature.
Installation and Safety Considerations
Installing gas logs in a double sided fireplace is not a DIY project for most homeowners. Gas connections must be made by a licensed professional. However, you can prepare by understanding the process. First, ensure your fireplace is compatible with gas logs. If you have a wood-burning fireplace, you'll need a gas line installed. This is a job for a professional. For ventless logs, you must ensure the room meets the minimum volume requirements specified by the manufacturer. For vented logs, the chimney must be inspected and cleaned. Always install a carbon monoxide detector in the room. For more on safety, see our guides on carbon monoxide signs from fireplace and can you leave a fireplace on overnight. If you're considering a DIY approach, read our DIY gas fireplace guide, but remember that gas work should be left to the pros. For maintenance, regular cleaning of the logs and burner is important. See our how to clean a gas fireplace burner guide. Also, be aware of fireplace ventilation requirements.
Maintenance Tips for Long-Lasting Performance
To keep your gas logs looking great and working safely, follow these maintenance tips:
- Annual Inspection: Have a professional inspect the logs, burner, and connections yearly. See our annual fireplace inspection guide.
- Clean Gently: Dust the logs with a soft brush. Avoid water or abrasive cleaners. For glass doors, see how to clean fireplace glass.
- Check for Soot: Soot buildup can indicate incomplete combustion. If you notice soot, call a technician.
- Test the ODS: For ventless logs, test the Oxygen Depletion Sensor periodically. Refer to your manual.
- Replace Worn Parts: Over time, logs may fade or crack. Replace them with replacing embers in a gas fireplace kits.
- Seasonal Care: Follow our seasonal fireplace checklist for spring and fall maintenance.

Can I use regular gas logs in a double sided fireplace?
No, regular gas logs are designed for single-sided fireplaces. They often have a flat back and an asymmetrical arrangement that looks unnatural from the back. You need a set specifically designed for see-through or double sided fireplaces, which has a symmetrical design and a burner that distributes flames evenly.
Are ventless gas logs safe for a double sided fireplace?
Yes, ventless gas logs are safe when installed correctly and used according to the manufacturer's instructions. They are equipped with an Oxygen Depletion Sensor (ODS) that shuts off the gas if oxygen levels fall. However, you must ensure the room meets the minimum volume requirements, and it's always a good idea to have a carbon monoxide detector. Check local codes, as some areas restrict ventless logs.
How do I measure my double sided fireplace for gas logs?
Measure the width, depth, and height of the firebox. For double sided fireplaces, measure the width of the opening on one side (they are usually the same). Choose a log set that is about 70-80% of the firebox width. For example, a 36-inch wide firebox needs a 24-30 inch log set. Always check the manufacturer's sizing chart.
Can I install gas logs in a double sided fireplace myself?
