DuraVent DirectVent Pro Vinyl Siding Standoff Kit: a slimmer siding shield for the square wall cap
The DuraVent DirectVent Pro Vinyl Siding Standoff Kit is a four piece heat shield for the Square Horizontal Cap at an outside wall. It is slimmer than the one piece version and goes together around the vent opening, starting at the top and continuing counterclockwise. It holds the hot cap away from vinyl siding to help prevent melting or warping. It also gives the cap a flat seat on lap or shake siding. 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.
This kit is for horizontal runs only. Choose the material first: standard galvanized steel, stainless steel, or copper. Then choose the 4 by 6 5/8 inch or 5 by 8 inch vent size. For a stucco wall, a counter flashing serves the same purpose and lets the stucco finish meet its edges. Have a round, sconce, or H2 cap? Choose the DuraVent DirectVent Pro Vinyl Siding Standoff Kit Small. The DuraVent DirectVent Pro 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 Vinyl Siding Standoff Kit for?
It is a four-piece heat shield that holds a DirectVent Pro horizontal termination cap off the wall so the cap’s heat does not warp or melt vinyl siding or other temperature-sensitive materials. It is also used on irregular sidings such as shiplap or shake shingles so the cap sits flat instead of being embedded in the siding. Horizontal terminations only.
Which cap and size does this kit fit?
This kit is sized for the Square Horizontal Cap. Choose the material (standard galvanized, stainless steel or copper) and then the vent size, 4 x 6-5/8 or 5 x 8 inch, on the selectors above. DuraVent’s cutout table lists the standard 4 x 6-5/8 kit at 13-1/2 by 13-1/2 inches and the 5 x 8 kit at 16 by 16 inches.
Do I need this if I have a round or sconce cap?
No; the Round Horizontal Cap, Sconce Cap and H2 cap take the smaller Vinyl Siding Standoff Kit Small, which is a separate listing. Match the standoff to the cap style first, then to the pipe size. If the wall is brick, block or fiber cement the appliance manufacturer may not require a standoff at all.
How is the standoff installed?
It mounts on the exterior wall around the framed vent opening, and the termination cap is then fastened to the standoff rather than to the siding. DuraVent’s instructions have the cap sealed to its mounting surface with a bead of non-hardening silicone and the supplied wood screws replaced with fasteners suited to the wall material.
Is it required by code?
DuraVent’s DirectVent Pro instructions call for the Vinyl Siding Standoff on buildings with vinyl siding or similar surfaces, and many appliance manuals repeat the requirement, so treat it as required whenever the cap would otherwise touch vinyl. The rest of the DirectVent Pro termination parts are listed separately.
