DuraVent DirectVent Pro DVA to CVS Adapter: a smaller pipe connection for longer power vented runs
The DuraVent DirectVent Pro DVA to CVS Adapter is a fitting that connects DirectVent Pro pipe to smaller DuraVent CVS pipe. It steps down to 3 by 5 inch CVS so a power vented gas fireplace run can reach farther through a tighter space. One end has a DirectVent Pro twist lock connection, and the other joins CVS. Choose a 4 by 6 5/8 inch or 5 by 8 inch DirectVent Pro connection on this page. DirectVent Pro is DuraVent’s pipe inside a pipe vent for direct vent gas fireplaces and stoves: exhaust goes out through the inner pipe and outside air comes in through the outer pipe.
Your fireplace maker must approve this change. DirectVent Pro is tested and listed with the appliance, so the appliance maker sets the allowed caps, spacing from materials that can burn, and run limits. Cold vent pipe can collect moisture from exhaust and corrode. Long sideways runs, extra bends, and outdoor exposure contribute to this. DuraVent calls for a yearly vent inspection.
