which took roughly 30 minutes and that information doesn't help you. What might help you is that all of the heat is vented out of the front and is nowhere near hot enough to set something on fire. But you don't want the heat vented out the back of the unit since it will be likely be pushed up against drywall (or worse, curtains or some type of fabric).

The one I bought didn't have a stone veneer like that one but the fireplace itself looks pretty similar. Has a remote that allows you to change pretty much anything (sound, color, heat/no heat, flame intensity, etc). I simply had to assemble the mantle, slide the fireplace in and attach with four wood screws.
