To install an electric fireplace in an existing fireplace, first remove any debris or old components, then ensure proper electrical connections, secure the electric unit inside the fireplace, and follow the manufacturer’s instructions for finishing touches and safety checks.
Converting your traditional fireplace to an electric model is a smart upgrade. It provides warmth without the hassle of wood or gas. This guide covers everything from safety checks to final trim installation.

Pre-Installation Preparation
Proper preparation ensures a smooth installation process. Follow these steps before inserting your electric unit.
1. Clean the Fireplace
Remove all ash, debris, and soot from your existing fireplace. Use a vacuum for thorough cleaning. Check for any structural damage that might affect installation.
2. Seal the Chimney
Install a chimney cap if missing. This prevents water intrusion and drafts. Close and seal the damper completely to retain heat. Use high-temperature silicone sealant for best results.
3. Check Electrical Requirements
Most electric fireplaces need a standard 120V outlet. If your fireplace lacks nearby power:
- Hire a licensed electrician for outlet installation
- Consider a dedicated circuit for larger units
- Never use extension cords permanently

Installation Process
Follow these steps for safe and proper installation of your electric fireplace insert.
1. Test the Unit First
Plug in the fireplace before installation. Verify all functions work properly:
- Flame effects
- Heating element
- Remote control (if included)
2. Position the Insert
Slide the firebox into the opening carefully. Maintain proper clearances:
Area | Minimum Clearance |
---|---|
Top to combustible materials | 3/8 inch |
Sides to walls | 1 inch |
Top to mantel | 2 inches |
3. Secure the Unit
Use included brackets to anchor the insert. Some models require:
- Side mounting screws
- Floor anchors
- Rear support brackets
Finishing Touches
Complete the installation with these professional finishing steps.
1. Install Trim Kit
Most inserts include decorative trim. Options include:
- Brushed metal surrounds

- Custom wood mantels
2. Hide Wiring
For a clean look:
- Use paintable wire channels
- Install in-wall cable management
