DuraVent DirectVent Pro Cathedral Ceiling Support Box: support for a vent through a sloped or flat ceiling
The DuraVent DirectVent Pro Cathedral Ceiling Support Box is a black box that supports vent pipe where it passes through the ceiling. It suits a sloped ceiling with no attic above it, but also works with a flat ceiling. The box is 14 inches tall and is cut to match the roof slope. At least 2 inches must remain below the ceiling. It includes ceiling trim and a clamp that carries the weight of the pipe above. 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.
Choose the box for 4 by 6 5/8 inch or 5 by 8 inch pipe. Under a vaulted ceiling, the run needs a chase, an enclosure around the pipe. At the roof, choose flashing to match the slope. This roof covering needs a storm collar above it, sealed to the pipe with non hardening sealant. Passing through another floor? See the DuraVent DirectVent Pro Ceiling Firestop plate. The DuraVent DirectVent Pro Cathedral Ceiling Support Box ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
