Tools Required to Install an Electric Fireplace Insert

Before you begin your DIY electric fireplace installation, having the right gear on hand is essential. Most modern inserts are designed for simplicity, but precision is key to a professional-looking finish.

• Measuring Tape: To verify your electric fireplace dimensions against the existing opening.

• Power Drill/Driver: For securing mounting brackets or framing.

• Level: To ensure the unit sits perfectly horizontal.

• Screwdriver Set: For fine-tuning the trim and glass panels.

• Wire Strippers/Voltage Tester: Only required if you are performing an electric fireplace insert wiring for a hardwired model.

• Shims: Helpful for leveling the unit if the floor of your existing fireplace is uneven.

Step-by-Step Electric Fireplace Insert Installation

Once you have unboxed your unit and confirmed it arrived in perfect condition, follow these steps to learn how to install the electric fireplace insert hardware correctly:

1. Measure and Prepare the Space

Measure the height, width, and depth of your existing fireplace opening. Compare these with the manufacturer's specs for your electric fireplace inserts. If the opening is too large, you may need a trim kit; if it's too small, you might need to look at electric fireplace logs as an alternative.

2. Check for Power Access

Most homeowners opt for a plug-in electric fireplace insert. Ensure there is a nearby outlet. If you are placing the unit inside an existing masonry fireplace, you may need to have an electrician install a fireplace electrical outlet inside the firebox so the cord remains hidden.

3. Clear the Chimney (If Applicable)

If you are installing a traditional wood-burning fireplace, ensure the damper is closed and sealed. While these units don't produce real smoke, sealing the flue prevents cold drafts from entering your home and heat from escaping.

4. Position and Secure the Unit

Slide the insert into the center of the opening. Use your level to check the alignment. Most units come with mounting brackets that screw into the side of the cabinet or the floor. For a recessed electric fireplace, you will secure the unit directly into the electric fireplace framing.

5. Attach the Trim and Glass

Once the unit is secure, attach the decorative trim or "surround." This covers any gaps between the insert and the wall. Finally, carefully install the front glass panel according to the manual.

Electrical Requirements for Electric Fireplaces Insert

One of the most overlooked aspects of an install electric fireplace project is the power draw. These units are powerful heaters, often pulling 1,500 watts on high settings.

• Standard Outlets: Most plug-in models work with a standard 120V outlet. However, fireplace electrical outlet requirements dictate that the outlet should be in good condition and not shared with other high-draw appliances like vacuums or space heaters.

• Dedicated Circuits: For the best performance, a dedicated circuit is highly recommended to prevent tripped breakers.

• Hardwired vs. Plug-in: If you prefer a seamless look without visible cords, you may choose a hardwired electric fireplace. This requires a permanent connection to your home’s electrical panel.

Common Mistakes to Avoid When Installing an Electric Fireplace Insert

Even experienced DIYers can run into trouble if they rush the process. Keep these tips in mind to ensure electric fireplace insert safety:

• Ignoring Fireplace Insert Clearance: Even though the front glass stays cool to the touch, the heater vent needs room to breathe. Blocking the intake or exhaust can cause the unit to overheat.

• Using Extension Cords: Never use an extension cord or power strip. These are not rated for the continuous high-amperage draw of a heater and can pose a fire risk.

• Incorrect Framing: If you are building a new wall for built-in electric fireplaces, ensure you follow the specific framing dimensions provided. Too tight of a fit can lead to vibration noise or overheating.

When to Hire a Professional for Electric Fireplace Installation? 

While many people find success with a DIY electric fireplace installation, there are times when it’s smarter to call in the pros.

1. Complex Wiring: If your home requires a new dedicated circuit or you are moving from a plug-in to a hardwired setup, hire a licensed electrician.

2. Structural Changes: If you need to cut into a load-bearing wall to create a recessed space, a contractor is necessary.

3. Gas Line Capping: If you are replacing a gas fireplace, a professional must safely cap the gas line before you begin your electric installation.

While the electric fireplace installation cost increases when hiring labor, the peace of mind regarding safety and code compliance is often worth the investment. For more information on safety protocols, read our article: Are electric fireplaces safe?

FAQ 

Can I install an electric fireplace insert myself? 

Yes! Most plug-in models are designed for easy DIY installation. If you can move the unit and have a nearby outlet, the process usually takes less than an hour.

Do electric fireplace inserts need a dedicated circuit? 

It is highly recommended. Because these units pull significant power when the heater is on, sharing a circuit with other electronics can lead to frequent breaker trips.

How much clearance is required around an electric fireplace insert? 

Clearance varies by model. Generally, you need at least 3 feet of clearance from combustible materials (like curtains or furniture) in front of the heater vent. Always check your specific manual for internal framing clearance.

Do electric fireplace inserts need ventilation or a chimney? 

No. Since they don't burn fuel, they produce no smoke, carbon monoxide, or fumes. You can (and should) seal off your old chimney to improve efficiency.

Is professional fireplace installation worth it for an electric fireplace insert? 

If you are uncomfortable with electrical work or need to modify your home's structure, yes. Professional fireplace installation ensures your unit is up to code and perfectly integrated into your home's aesthetic.
