DuraVent Model BV Oval Rigid Pipe: straight gas vent lengths for inside a stud wall
The DuraVent Model BV Oval Rigid Pipe is a straight length of flattened gas vent that runs inside a stud wall, most often above a gas wall furnace. 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. Oval sizes describe the flow of the matching round pipe, not the width. The 4 inch fits a 2 by 4 wall and is also listed for use above a recessed gas wall furnace. The 5 inch fits a 2 by 4 or 2 by 6 wall. The 6 inch fits a 2 by 6 wall.
Choose 4, 5, or 6 inch, then your length. The 4 and 5 inch sizes come in 6, 12, 18, 24, 36, 48, and 60 inch lengths. The 6 inch size offers lengths from 6 to 36 inches. Allow for 1 inch lost inside each joint when adding up the run. Do not cut this pipe. Need to fill the remaining gap? Use the DuraVent Model BV Oval Adjustable Pipe sliding length. The DuraVent Model BV Oval Rigid Pipe ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
