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.

Planning Your Installation:

  1. For vertical gas stove installations, measure the height from the stove outlet to the ceiling to determine the length of black pipe required. Select a ceiling support/wall thimble cover or a cathedral ceiling support box.
  2. To determine the length of galvanized pipe required, measure the ceiling thickness and the vertical rise in an attic or second story. Firestops are required at each floor level beyond the first floor ceiling support/wall thimble cover or cathedral ceiling support box. If an offset is required to avoid obstructions, use a pair of 45° elbows. For proper support, use elbow straps with offsets. Use wall straps for long vertical runs. Attic Insulation Shield is required in attic.
  3. Measure the roof pitch. Select the proper flashing and storm collar. Determine the minimum height above the roof.
  4. For horizontal installations, check the appliance manufacturer’s instructions for minimum rise and maximum horizontal run. A snorkel termination may be used if height restrictions prevent adequate rise above the appliance. Select the appropriate Horizontal Termination Cap (see appliance manufacturer installation instructions). To protect vinyl siding, select vinyl siding standoff. Check appliance manufacturer’s instructions for wall thimble and firestop requirements.

Design Recommendations

  • The following design recommendations are general guideline to assist in the design and selection of venting components for your installation. Always follow Duravent Installation instructions enclosed with the cap or support box before installing your chimney system. Installation instructions can be viewed online at www.duravent.com, under Catalogs and Instructions. Important: Check the manufacturer’s rating plate and instruction manual to confirm that the Duravent direct vent system is approved for use on the brand name appliance you have selected.
  • The inner and outer pipe diameters should match the outlet size of the appliance.
  • Check the appliance manufacturer’s installation instructions to confirm which types of vent configurations are permitted (i.e. horizontal, vertical, chimney reline, etc.). Also, check for any venting restrictions such as maximum horizontal run, minimum and maximum vertical rise, maximum offset, etc.
  • Be fire safe! Maintain at least the minimum clearances (air-space) between the vent pipe and nearby combustibles, as specified in the appliance manufacturer’s installation instructions. Use proper support and bracing. Follow local building codes and have your venting system inspected.

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.
