DuraVent DirectVent Pro Vinyl Siding Standoff Kit Small: one spacer kit for three smaller wall caps
The DuraVent DirectVent Pro Vinyl Siding Standoff Kit Small is a four piece heat shield that sits between an outside wall cap and the siding. It fits the Round Horizontal, Sconce, and H2 caps on horizontal vent runs only. The same kit works with both 4 by 6 5/8 inch and 5 by 8 inch pipe, so you only pick the material. 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.
A hot cap can soften vinyl enough to warp or melt it. This kit spaces the cap away from the siding and provides a flat mounting surface on shingle or lap siding, too. Choose galvanized steel, stainless steel, or copper to match your cap. On stucco walls, a counter flashing serves the same purpose and gives the stucco an edge to finish against. Using a square cap? See the DuraVent DirectVent Pro Vinyl Siding Standoff Kit for square caps. The DuraVent DirectVent Pro Vinyl Siding Standoff Kit Small ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.

FAQ
What is the Vinyl Siding Standoff Kit Small used for?
It is the four-piece heat shield for the smaller DirectVent Pro horizontal caps: the Sconce Cap, the Round Horizontal Cap and the H2 Horizontal Cap. It spaces the cap off vinyl or other heat-sensitive siding to prevent warping or melting, and keeps the cap flat on irregular surfaces such as shake shingles or shiplap. It is for horizontal terminations only.
Does it fit both vent sizes?
Yes, unlike the standard standoff this small kit fits both 4 x 6-5/8 and 5 x 8 inch DirectVent Pro, so you only choose the material: standard, stainless steel or copper to match the cap finish. DuraVent’s cutout table lists the small kit at 10-1/2 by 10-1/2 inches.
Which standoff do I need for a Square Horizontal Cap?
The full-size Vinyl Siding Standoff Kit, not this one; the square cap is larger and needs the 13-1/2 or 16 inch kit. Identify the cap approved in your stove manual first, then pick the matching standoff. Round, sconce and H2 caps use this small kit.
How does the cap attach to the standoff?
The standoff pieces mount around the vent opening on the exterior wall and the cap is screwed to the standoff instead of the siding, sealed around its edges with non-hardening silicone as DuraVent’s instructions describe. Use fasteners suited to the wall behind the siding rather than the wood screws supplied with the cap if needed.
When is a standoff required?
Whenever the horizontal cap would otherwise sit against vinyl siding or another temperature-sensitive material; DuraVent’s DirectVent Pro instructions specify it for such walls and most appliance manuals agree. Caps, thimbles and the other DirectVent Pro termination parts are sold separately.
