The dampener is nearly useless; it has two adjustments wide open or completely closed. most dampeners can be modulated so that all of the heat doesn't go up the chimney. The control for the dampener is located above the fire box in the chimney making it impossible to close the dampener until the fire box cools down. It doesn't come with a fresh air kit. If one overlooks buying any of the items needed to operate the insert it doesn't do any good calling the factory out in Ca. you are advised to go back to the web where you bought the fire place and order it there.
The glass doors we bought are manufactured with 1/4 "spaces between the glass panels. This does not allow for a sealed fire box. The door for the out side air is spring loaded closed, which leads me to wonder how the out side air gets into the fire box and what good an out side air kit is. This is my second fire place insert. The first lasted 30 yrs. and all of the items I mentioned the FMI lacked: my old one had. I wish I had researched my old box and purchased it. I Would not recommend this insert FMI Model B42L to anyone. .

The Best Fireplace I have Installed at the Best Price.
The dimensions were as stated in product information and it fit perfectly in the rough opening. It really looks great now that it is installed.
The delivery was timely without damage.

The fireplace does look and work great.
Pros42 inch is a good size. You don't have to be as selective on wood sizes.
ConsThe item is great. Packaging and handling were the only problems.
