DuraVent DirectVent Pro Wall Firestop: a protective plate for a vent through wood framing
The DuraVent DirectVent Pro Wall Firestop is a plate that protects a wood framed wall where the vent pipe passes through it. It goes at the wall opening on a horizontal run, not a run through the roof. It is the simpler alternative to a wall thimble, a sleeve around the pipe, when the appliance maker allows either part. The appliance maker decides which protection is needed. In Canada, a two piece wall thimble is required. 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.
Choose the size that matches your vent: 4 by 6 5/8 inch or 5 by 8 inch. DirectVent Pro is tested and listed with the gas appliance, so the appliance maker sets the approved caps and vent layout limits. This firestop is not for the H2 cap. Using that cap? Choose the DuraVent DirectVent Pro Wall Firestop 2 for H2 caps. The DuraVent DirectVent Pro Wall Firestop ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
