Hello - I am getting a gas fireplace installed and the fireplace company asked me to modify the electrical outlet shown below to a 110v whip with a 2 feet slack for the fireplace to be plugged into. I need to submit the fireplace permit along with the electrical permit together. I am having a difficult time finding an electrician for this. Can someone please let me know if this is fairly common and easy to do? Pages 44-45 in the manual below show the electrical connection.
