DuraVent Model BV Firestop Support Plate: carries the vent and closes the floor opening
The DuraVent Model BV Firestop Support Plate is a two piece plate that holds a large gas vent where it passes through a floor. It also serves as the firestop, closing the opening around the pipe. Its matching halves fit around the pipe and bolt together at the recessed area near the pipe’s top. The plate can carry up to 30 feet of vent. Model BV is DuraVent’s Type B gas vent, the double wall pipe that carries the exhaust from a gas furnace, boiler, or water heater out of the house.
Choose a size from 10 to 30 inches to match your vent. DuraVent requires this plate in a fully framed opening, with 1 inch of space between the vent and wood framing. It fastens only to the top of the opening. Supports go at least every other floor, no more than 30 feet apart. An adjustable pipe goes directly below each supported section to line up the pipe’s recess with the plate. Need that connecting length? See the DuraVent Model BV Large Diameter Round Adjustable Pipe. The DuraVent Model BV Firestop Support Plate ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
