The result is a cleaner, safer, and simpler fireplace experience without venting or gas bills.
This step-by-step guide covers everything: the tools and parts you’ll need, safety warnings, common mistakes to avoid, and when to call a licensed plumber or electrician. By the end, you’ll know exactly how to convert your gas fireplace to electric with confidence.
Can You Convert a Gas Fireplace to Electric? Yes – Here’s How
You can convert a gas fireplace to electric by safely disconnecting or capping the gas line, measuring the firebox to fit an electric insert, and preparing the electrical supply. Electric inserts fit inside the existing firebox, need no venting or gas connections, and offer efficient, adjustable heat with realistic flame effects.
You can convert a gas fireplace to electric by safely disconnecting or capping the gas line, then installing an electric fireplace insert that fits your firebox. This swap removes the need for venting and gas supply, cutting maintenance and safety concerns.
The main steps start with shutting off and capping the gas line to prevent leaks. Next, measure the firebox interior—not just the visible opening—to ensure the electric insert will fit properly. Then assess the electrical supply, since electric inserts need a dedicated 120 V outlet on a suitable circuit. Finally, install the electric insert, which usually just plugs into the wall.
Unlike gas fireplaces, electric inserts require no venting, no gas line, and no chimney maintenance. They produce heat by converting electricity directly, with no emissions like carbon monoxide or nitrogen oxides. While electric inserts generally provide less heat than gas units, they offer adjustable heat settings, realistic LED flame effects, and safer operation with minimal upkeep.
Converting a gas stove fireplace to electric is straightforward if your firebox is compatible. Electric inserts often fit standard openings and can be a cleaner, simpler, and more flexible heating option. The job isn’t always easy, but it’s doable for many homeowners and can be completed more quickly and affordably than replacing the entire fireplace.
Safely Cap or Remove the Gas Line Before Installing Electric
Before installing your electric insert, have a licensed plumber or gas technician shut off the gas supply and either cap or remove the gas line to prevent leaks. Never attempt to disconnect gas lines yourself; improper handling risks fire or carbon monoxide exposure. Confirm the gas valve is fully closed and test for leaks before proceeding.
Begin by turning off the gas at the main valve supplying the fireplace. This valve is usually found near the fireplace or at the gas meter. Then disconnect the flexible gas line from the fireplace’s shut-off valve.
To cap the gas line at the fireplace, use a properly sized threaded cap with pipe joint compound rated for gas lines. Tighten it securely to prevent leaks. After capping, test for leaks with a gas leak detector or a soapy water solution. Bubbles indicate a leak that must be fixed immediately.
In some cases, it’s safer and sometimes required to remove the entire gas line back to the main shut-off. This is common if the line won’t be used elsewhere or if local regulations demand it. Check your local building codes and permit requirements before proceeding.
Hiring a licensed plumber is often the best choice. They have the tools and experience to handle gas line work safely and can obtain necessary permits. Gas leaks are dangerous and can cause fires or explosions, so never skip proper leak testing and code compliance.
You may wonder if you need an electrician when removing a gas fireplace and replacing it with an electric unit. Yes, if the electrical outlet and circuit aren’t already suitable for the electric insert’s power needs, an electrician should install or upgrade wiring safely and according to code.
Measure Your Firebox for the Right Electric Insert
Measure the width, height, and depth of your existing firebox to choose an electric insert that fits snugly. Most inserts list their required firebox dimensions; check both the visible opening and interior space. A tight fit avoids gaps that reduce efficiency and spoil the look. If your firebox is non-standard, custom inserts are an option but cost more.
Start by measuring the height, width, and depth of the interior of the firebox. Many people mistakenly measure only the opening, but electric fireplace inserts need enough depth—typically between 12 and 16 inches—to fit fully inside without sticking out or causing installation issues.
Fireboxes are often tapered or irregularly shaped. Measure depth at both the top and bottom because the firebox may narrow toward the back. This can make a standard insert too large at one end but loose at another. Knowing these details helps you pick inserts with slim profiles or special trim kits to fill gaps.
If your firebox is smaller than typical, some electric inserts are designed with a shallower depth to fit tight spaces. Smaller inserts can also be mounted with a surround panel or faceplate that overlaps the edges, hiding any gaps and giving a finished look.
Avoid guessing or rounding up measurements. A too-large insert won’t fit, and a too-small one may look awkward or let cold air in. Accurate measurement prevents ordering the wrong size and the hassle of returns or modifications.
Replacing a gas fireplace with an electric insert is common, but each firebox is unique. Take your time measuring all dimensions precisely, and check the insert’s specifications and minimum depth requirements before buying.
Electrical Work Required for an Electric Fireplace Insert
Electric fireplace inserts need a dedicated 120 V outlet rated for at least 15 A, ideally on a separate circuit to avoid tripping breakers. Extension cords and power strips are unsafe for these heaters. If your firebox lacks a nearby outlet, an electrician can install one. Some inserts include adjustable thermostats and remote controls; check that wiring supports these features.
These inserts require a dedicated 15-amp or 20-amp circuit. Sharing a circuit with other appliances risks tripping breakers, especially if your existing outlets already have high loads. Confirm the circuit’s capacity and what else is on it before installation.
Some electric fireplace inserts plug directly into a standard 120 V outlet, making installation simpler if you have a suitable nearby outlet on a dedicated circuit. Others are hardwired, requiring electrical line conversion from the gas fireplace’s setup to the insert’s specifications.
Changing the power source involves disconnecting any gas valve wiring and installing proper electrical connections. This is not a DIY job unless you are experienced with electrical codes and wiring. Hiring a licensed electrician ensures the work meets safety standards and local code requirements.
If your panel lacks capacity for a new dedicated circuit, the electrician can add a new circuit breaker or upgrade the panel. Safety precautions include turning off power before working, using proper wire gauge and connectors, and installing GFCI protection if required by code.
Planning electrical work before buying the insert saves time and surprises. A qualified electrician can inspect your home’s wiring and recommend the best solution for a safe, reliable electric fireplace setup.
Plug-in electric inserts are easier to install but still depend on proper circuit capacity. Hardwired units offer cleaner installation but always require professional electrical work.

Common Mistakes That Cause Damage, Leaks, or Poor Performance
Common mistakes include forgetting to cap the gas line properly, using an extension cord for the electric insert, and choosing an insert that doesn’t fit the firebox. These lead to leaks, electrical hazards, or poor heating performance. Always follow manufacturer instructions and local codes. Test your setup carefully before relying on it for warmth.
Failing to test the gas line cap for leaks after shutting off gas risks dangerous leaks. Use a gas leak detector or soapy water to check all capped connections thoroughly before finishing the job.
Measuring only the visible firebox opening instead of the full interior depth causes insert fit issues. Most electric inserts need at least 12 to 16 inches of firebox depth for clearance and airflow. Measure inside the firebox walls, not just the front frame.
Leaving the damper open or partially open lets cold air draft in and reduces the heat and flame effect. Close or remove the damper completely to stop drafts and maintain the insert’s visual impact and efficiency.
Overloading electrical circuits by plugging the insert into existing lines without checking capacity leads to breaker trips or fire hazards. Electric inserts often draw 1,500 watts or more, about 12.5 amps at 120 volts. Dedicated 15-amp circuits or upgrades may be necessary.
Skipping permits and unlicensed work on gas or electrical connections risks code violations and unsafe conditions. Hiring licensed professionals for gas line capping and electrical upgrades ensures compliance and safety.
Installing the electric insert without cleaning out the firebox leaves creosote, debris, or dust that can damage the insert or block airflow. Clean the firebox thoroughly before installation to protect components and maintain proper ventilation.
