Ortal's modern Powr Vent System enables the creativity of design without limitations.  This fan-assisted direct vent technology can move exhaust up to 165 feet away from the fireplace, increasing your venting range by 125 feet beyond direct vent.  Ortal offers power vent options to give you even greater design freedom:  Inline-90 Power Vent System, Inline-180 Power Vent System, Vertical Power Vent System and Flush Horizontal Termination Power Vent Sytem. 

The Enervex Power Vent is a stand-alone sytem and can be added to any fireplace Ortal has in teh field.  No conversion kit is necessary.
