DuraVent DirectVent Pro 8×11 Vinyl Siding Standoff Kit: a heat shield that helps the wall cap sit flat

The DuraVent DirectVent Pro 8×11 Vinyl Siding Standoff Kit is a four piece stainless steel spacer for the outside wall cap. It assembles around the vent opening to shield vinyl siding from the cap’s heat. It also provides a flat mounting surface on brick veneer, stucco, ship lap, or shake shingles. The cap fastens to the standoff rather than the siding. DirectVent Pro 8×11 is DuraVent’s large size pipe inside a pipe vent for big direct vent gas fireplaces, with an 8 inch exhaust pipe inside an 11 inch air pipe.

This vent size connects only to matching parts. DuraVent makes two adapters to transition to or from its 5 by 8 inch DirectVent Pro pipe where the fireplace maker approves. A complete run is assembled from separate parts, not supplied as a ready made DuraVent kit. Using ship lap or shake siding? Consider the DuraVent DirectVent Pro 8×11 Vinyl Siding Standoff, the one piece version. The DuraVent DirectVent Pro 8×11 Vinyl Siding Standoff Kit ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.

FAQ

What is the 8×11 Vinyl Siding Standoff Kit?

A four-piece stainless steel heat shield that spaces the DirectVent Pro 8×11 Horizontal Cap off the wall, protecting vinyl siding or other temperature-sensitive materials from the cap’s heat. It also lets the cap sit flat on irregular surfaces such as veneer brick, stucco, shiplap or shake shingle siding rather than being embedded in them.

Is it only for vinyl siding?

No. DuraVent specifies it for any temperature-sensitive siding and for any irregular surface where the horizontal cap would not seat flat, which is why brick veneer and stucco are named. If the wall is smooth and non-combustible the fireplace manual decides whether a standoff is needed.

Does it fit the standard DirectVent Pro caps?

No; it is built for the 8 x 11 inch horizontal cap only. The 4 x 6-5/8 and 5 x 8 inch DirectVent Pro caps use their own standard or small vinyl siding standoff kits. Match the standoff to the cap size and style you are installing.

How is it installed?

The standoff pieces mount around the framed opening on the exterior wall and the Horizontal Termination Cap is fastened to the standoff instead of the siding, then sealed around its edges to keep water out. Use fasteners suited to the wall behind the siding. The wall thimble and horizontal firestop are separate parts.

Where do I find the cap and the rest of the vent?

The 8×11 Horizontal Termination Cap, wall thimble, firestops, pipe lengths and elbows are all in the DirectVent Pro 8×11 category, most of them on the Customize your Kit page. Clearances and termination distances come from the fireplace manufacturer’s instructions.
