DuraVent DirectVent Pro Small Wall Thimble: a wall sleeve sized to stay behind smaller caps
The DuraVent DirectVent Pro Small Wall Thimble is a two piece sleeve that carries the vent pipe through a wall. Its outside plate stays behind the smaller round horizontal, sconce, and H2 caps rather than sticking out past their edges. It provides the complete wall passage and a firestop, which helps protect the framing around the opening. This is DuraVent’s preferred thimble for the H2 cap. 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 4 by 6 5/8 inch or 5 by 8 inch size to match your vent. For a wood framed wall, the appliance maker may require a thimble or wall firestop for added protection around the pipe. Canada requires a two piece wall thimble. Match the thimble to the cap style too, since the square horizontal cap uses the full size wall parts. Using that square cap? See the DuraVent DirectVent Pro Wall Thimble. The DuraVent DirectVent Pro Small Wall Thimble ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
