DuraVent DirectVent Pro Wall Firestop 2: the wall plate for the H2 cap
The DuraVent DirectVent Pro Wall Firestop 2 is a plate for the wall opening where a vent pipe passes outside. It is made for the H2 cap, the compact square cap used at the end of a horizontal run. That cap needs a different plate from the standard wall firestop. This part fits 4 by 6 5/8 inch pipe and is for through wall runs only. 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 appliance maker decides whether the wall opening needs a firestop. Wood framing may need this extra protection or a wall thimble, a sleeve around the pipe. In Canada, a two piece wall thimble is required. Wind and nearby trees or taller rooflines can interfere with vent airflow. DuraVent offers high wind caps for wall and roof exits, plus wind guards that attach over a cap. Using another cap style? See the DuraVent DirectVent Pro Wall Firestop standard plate. The DuraVent DirectVent Pro Wall Firestop 2 ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
