In Wall wiring to TV Niche above vented gas fireplace

post #1 of 2
Thread Starter 
I have a setup with a large TV Niche above a direct vent gas fireplace. I am hoping to run speaker wire and HDMI to the TV Niche through the walls (going through crawl space to access my receiver across the room).

My concern is getting wires up the wall behind the fireplace. I know there is a horizontal beam in the wall just about lined up with the shelf of the niche - I should be able to drill a hole through this beam from the wall plate hole I made in the drywall of the niche. I can get under the fireplace in the crawlspace, so I am assuming I can drill up through the floor beam from in the crawl space. I am concerned about fishing the wire through the wall behind the fireplace? I guess I'll just need to worry about getting around the fireplace vent tube? There should be open space between the back of the fireplace and the wall, correct? Will there be insulation behind the fireplace?

My other option is just going through the back wall of the niche straight outside, and running the wire behind the vinyl siding down to re-enter the crawlspace. This is how a user described doing it here:

Is that legit?

Any other ideas? My room setup looks similar to user in this post:

but no one on that forum was particularly helpful.

Thanks.

I'm pretty sure there is a minimum clear distance that must be maintained between combustibles and the vent pipe for vented gas logs. This includes insulation as well a any cables. Vent-less logs are a little different.

Can you post pics of your space? I did something similar recently and made sure I ran the wires around the side of the fireplace (opposite side of the framing stud) to make sure I was clear of any potential heat sources back there.
