The Full Picture
Start With Your Existing Fireplace
The biggest difference between a gas insert and a new gas fireplace is that an insert is designed to go inside an existing fireplace.
That means your existing fireplace becomes an important part of the buying decision. The width, height, and depth of the opening, along with its condition and configuration, all need to be considered.
Before choosing an insert, have the existing fireplace properly measured and assessed to confirm compatibility with the model you're considering.
What About the Chimney?
Many gas inserts are installed within an existing masonry chimney or fireplace structure, using a dedicated venting system.
The condition and configuration of the existing chimney can influence what is required for installation. A qualified professional can assess the existing fireplace and determine the appropriate venting solution.
How Much Heat Do You Need?
Think about what you want your insert to accomplish.
If you're primarily interested in ambiance and the convenience of gas, your heating needs may be different from someone looking for a significant source of supplemental heat.
Compare the heat output of different models and consider the size and layout of the room.
How Will It Look?
A gas insert can significantly change the appearance of an existing fireplace.
Consider the style of the insert, flame presentation, log or media options, surround and finishing details. You can maintain a traditional fireplace aesthetic or use an insert to give an older fireplace a more contemporary appearance.
What Features Matter?
Depending on the model, gas inserts may offer:
- Remote controls
- Thermostatic operation
- Adjustable flame height
- Lighting features
- Different log and ember options
- Heat management
- Other convenience controls
Think about which features will make the fireplace more enjoyable and easier to use in your home.
What Does Installation Involve?
Installing a gas insert may require more than simply placing the appliance into the existing opening.
Depending on the installation, work may involve venting, gas connections, electrical connections and modifications to the existing fireplace.
The insert must be installed according to its specific installation instructions and applicable requirements.
How Will You Operate Your Insert?
Gas inserts are designed to provide convenient operation. Depending on the model, you may be able to control flame height, heat output and other features using a remote or thermostat.
Understanding the available settings can help you balance warmth and ambiance based on how you're using the room.
How Do You Clean a Gas Insert?
The glass and surrounding areas should be cleaned according to the Owner’s Manual instructions.
Dust and debris can also accumulate around the fireplace over time. Keep the area clean and avoid disturbing logs or other media unless the manufacturer's instructions specifically allow it.
Always ensure the insert is completely cool before cleaning.
What Maintenance Is Required?
Gas inserts contain combustion and venting components that require periodic attention.
Professional servicing can help identify issues with the burner, pilot, venting, gas connections, and other components.
Follow your owner's manual for recommended maintenance and servicing intervals.
Gas Insert Safety
Always follow the Owner’s Manual operating instructions and maintain the required clearances.
The glass and surrounding surfaces can become hot during operation. Keep children, pets, and combustible materials away from the fireplace and follow all safety recommendations.
If you notice unusual odors, sounds or changes in performance, stop using the appliance and contact a qualified professional.
Getting the Most From Your Insert
Your insert can provide both ambiance and heat, so take advantage of its available settings.
Experiment with flame and heat levels to find what works best for your space, and use the fireplace regularly enough to understand how its controls and features work.
The Bottom Line
A gas insert is a convenient way to update an existing fireplace, but compatibility is the key first step. Understanding your existing fireplace, venting options, heating needs, and desired features will help you choose the right insert and prepare for installation.
With proper installation, operation, and maintenance, a gas insert can provide years of warmth and ambiance.
