You are correct, that is a direct vent unit. In my opinion there isn't much of a difference in the two, so hopefully one of our members with more expertise regarding them will chime in.
They are both motorized fans that pull or push the Flue gas outside, and create a negative firebox pressure, using two different style fan blades.
The power vent is mounted outside, requires a barometric damper, and is subjected to the weather.
The direct vent is mounted inside, out of the weather,and seems to be engineered for the stove, since some manufacturers state that a barometric damper is not required.
I really don't know if it's better to push the exhaust out or pull it out, or is this another Ford Chevy Dodge thing. :discuss:
