Ortal’s modern Power 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. The forced air stream has enough power to allow for three times the number of bends in your venting run, giving you dramatically more flexibility in the placement of your pipe. All of which means you can install your fireplace in apartments, upstairs rooms, and other once-forbidden spaces. Ortal’s Power Vent System utilizes DuraVent’s 35CVS pipe, which can run vertically, horizontally, and downhill while maintaining ideal air flow.
