Has anyone installed a outlet for one of these units? I have a customer that purchased one and the sales rep has told me that he needs a 120v outlet on the inside of the existing fireplace. I asked if the area will get hot? sales guy says no. It would be mounted on fireplace side wall down low and the insert sits in front of the outlet. I'm thinking that I will need to drill hole through hearth floor with a EMT sleeve into metal box, fed with romex from basement. Any experiences or recommendations would be appreciated??
