Just had a Regency P33CE-10 fireplace installed by the dealer in our vaca home. He sent some pics today and he mounted an electrical box just to the right of the fireplace for the remote receiver. I’m not crazy about the location but he said he couldn’t mount it on the rt wall because of window framing and the wire is too short to mount on the wall to the left. Going to have stone installed soon but there’s gotta be a better place to put this. Can I get an extension for this wire so it can be mounted on the wall to the left?
