Relocating a simple indoor outlet

[Coloshaver]

This ought to be easy, but I don't know the code and want to it right the first time.

I'm installing a gas fireplace. I've got to build a frame to mount it. The newly built frame will be dry walled and totally enclosed. Right now, there is an electric outlet dead center behind where the gas fireplace will mount. I need to move it over about 18". The new outlet will power the gas fireplace fan and probably be hardwired. It will be inside the framed fireplace surround and not accessible once the fireplace is built in.

Since it will be totally covered, I would run Romex from the old box to the new one mounted either on the now enclosed wall or on one of the 2x4s on the frame. Would this pass the "rough in" inspection?
If not, what would I need to do to pass?

Thank you in advance for your help

If you use the old box as a junction box, it has to be accessible. The box in the picture is so low that it looks to me like it was added after the home was built. Maybe not, but you could get lucky and it will have one cable to it from the basement. If that's the case, pull the cable down and put the jbox down there. This is all based on a theory that you have a basement, and it's either not finished or has a drop in ceiling. I don't do much as far as new construction, but the gas fireplaces I have seen had the receptacle inside the fireplace. Just leve a length of romex to go inside of it.

Is the existing box in the middle or at the end of the existing run?

There is no basement. Only a crawl space. I got down there today and found a way to add an "accessable" junction box and run Romex up through the floor into the enclosure that will hold the fireplace.

The box in the picture is at the end of a run, but the run is through the wall and I can't get to it. I'll just wire nut the ends and put a blank cover on that box.

Thanks for the help.
