My wife tried to slide a lever that controls the ductwork dampers for our fireplace but the lever would not move completely over. The fireplace ships with a piece of aluminum is supposed to be removed during installation if the fireplace uses the options that we are using. The installed had not removed the aluminum piece so we had to take the front plate off the fireplace in order to access the aluminum piece. The stone around the fireplace is so tight, we almost didn't get the front plate off. However, after some cajoling, we finally got the front plate off and were able to remove the aluminum piece. We would have been in a real pickle if we weren't able to get the front plate off.
While the front plate was off, my wife applied some mortar between the hearth stone and the fireplace and wall in order to fill in the gap. We wanted to prevent hot embers that escape the fireplace from finding their way down the gap and burning down our house.
My wife asked me the question, "Who does this kind of stuff?" She was referring to the normal construction process when you have a general contractor. Filling in this gap was a tedious detail type of procedure. My wife concluded that this part might get skipped in some house builds.
