Electric fireplaces have a power cable that typically comes out of the back or side of the appliance.
For example, the power cord for my freestanding electric fireplace stove is located at the back of the unit, at the base where the heater component is.
The images below show where the power cable comes out the back of the fireplace, and how long you can expect the power cord to be.
Electric fireplaces will come with the power cable pre-assembled, and so the fireplace power cord can simply be plugged straight in at the wall out of the box. (Some assembly is typically required and you can see how I put together and setup my freestanding electric fireplace here.)
The socket also needs to be switched on at the wall for the electric fireplace to work.
With the electric fireplace plugged in and turned on at the wall, you can use the controls to turn on the flame effect and the heater.
Here’s what the controls look like on my freestanding electric fireplace:
