I have had a few differences on this. I have the old ash clean out that I can snake an electircal line through and be able to have the power cord in between the insert and the old firebox. I have had 3 different dealers out and 2 said that would be fine, and the other said no way best if you run the cord along the hearth and to the nearest outlet. I am sure that there are codes for this, but I for one would think that it would get very hot and having it in the old bos would be a hazard.
Any thoughts
