Again, this kit is designed for use with 4 inch inner diameter DuraFlex pipe, but it's also intended to work with a DuraVent DuraFlex Zero Clearance insulation sleeve to meet the UL 1777 standard for masonry chimneys and wood burning appliances. The kit helps ensure safe and efficient venting of your heating appliances, plus it protects your masonry chimney from the damaging effects of flue product condensation.
With your purchase you'll receive a rain cap, a collar plate, a tee section, and a tee cover. This combination provides a means of finishing the venting installation on the roof, as well as a way to add more than one appliance or get around an obstruction. When you weigh the benefits of this kit against the cost, it's easy to see why so many homeowners and chimney professionals rely on a DuraFlex SS All Fuel Component Kit in their venting installations.
