DuraVent DirectVent Pro Concentric Flex: a bendable section for getting around obstacles
The DuraVent DirectVent Pro Concentric Flex is a bendable vent section with twist lock collars at both ends. It curves around a joist or beam in place of two elbows. 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. The vent is tested and listed with the appliance, not separately. The appliance maker sets approved caps, clearances from materials that can burn, and vent layout limits.
Choose the 4 by 6 5/8 inch or 5 by 8 inch size, then a 3, 5, or 10 foot length. The inner and outer aluminum flex pipes arrive compressed. Stretch them only as far as needed. Avoid tight bends or turns beyond 90 degrees. Pipe above needs separate support. Use this flex only with appliance maker approval, including permission for placement inside walls or enclosed pipe shafts. Prefer rigid elbows? The DuraVent DirectVent Pro 45 Degree Elbow has a fixed angle and swivels at its base without loosening the twist lock joint. The DuraVent DirectVent Pro Concentric Flex ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
