Power vent vs direct vent the main difference between power vent and direct vent is that dv pulls intake combustion air from outside where power ven uses air from inside.

The hot exhaust gases from a natural draft water heater rise through an open draft diverter and out through a metal duct. If it is a natural vent type water heater you can not vent it through the side wall it has to vent above the roof.
