DuraVent DirectVent Pro Ceiling Firestop: closes the floor opening around an upstairs vent run
The DuraVent DirectVent Pro Ceiling Firestop is a plate that closes the framed opening where the vent passes through a floor. DuraVent requires it at the second floor and each floor above, or at every floor in Canada. The opening is framed to fit the plate. The first ceiling uses a support cover or cathedral ceiling support box instead. Choose the 4 by 6 5/8 inch or 5 by 8 inch size to match your vent. 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.
Above the first floor, the run must be enclosed through occupied rooms, closets, and storage areas. An attic needs an insulation shield or enclosure, and a vaulted ceiling needs an enclosure. Wall straps hold the run every 4 feet. The vent is tested and listed with the appliance, whose approval governs caps, clearances, and vent layout. Heading into the attic? See the DuraVent DirectVent Pro Attic Insulation Shield sleeve. The DuraVent DirectVent Pro Ceiling Firestop ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
