Answer:
The most popular type of vented gas fireplace is called a "direct vent" unit. This type of fireplace, such as this unit, utilizes a sealed firebox for operation.
The firebox has a pane of tempered or ceramic glass across it's opening and utilizes a double layer pipe for venting. The inner pipe vents exhaust gases, while the outer layer draws combustion air. It does not have any interaction with room air and they are relatively efficient. These can also be vented vertically and horizontally.
Vent free fireplaces have no chimney system at all. They use a sophisticated burner and valve system that allows all of the supplied fuel to be burned cleanly. This allows safe operation and high efficiency. The only downside to vent free is the potential for them to add residual moisture to the room and they can draw air through small crevices in your homes outer walls. These types of units are best for homes with large spaces and plenty of combustion air.
