Once you’ve decided on the type of installation, the owner’s manual will have specific details for framing, securing the unit, wiring, and clearances.
Most electric fireplaces come with a plug on a six-foot cord. Depending on the installation, many fireplaces are hard-wired. A qualified electrician will remove the corded connection and wire the appliance directly to the home’s electrical panel if necessary. Checking to see if the cord connects to the right or left side of the fireplace would be good intel for the electrician. They will also ensure local codes are followed.
