I need to run a 120V receptacle circuit and a 3/4" stub up for low voltage down a chimney space. They (the owner) say the chimney is built with double wall flue with 8-10" airspace, and then then the two courses of brick. I have no idea what the ambient temp would be in this chase. Sounds easy enough. Has anyone here ever done this? I have seen receptacles on masonary hearths but they were all new construction, never old work.

Thanks in advance.
