I'm considering converting a faux fireplace to a working one with one of those self-contained gas units. For the gas lines I'm going to have professional do it, but wanted to get some advice on how invasive extending my existing gas lines would be - I'm not at all familiar with what's available these days for running such lines, what I have currently is black piping.
The fireplace is on the first floor and is probably ~30 feet from the gas meter in the basement on the same side of the house. In the theory the line just needs to run in the basement ceiling on a straight shot over to the fireplace, but the ceiling is not open and is plaster and lathe, which is a real nightmare to open up in my experience. Is it reasonable to assume that to run the line they'd need to open up the ceiling along the full length of the run, or is there some clever way this is done less invasively?
