DuraVent Model BV 10 and 12 Inch Large Diameter Round Rigid Pipe: straight vent sections with a push and turn connection
The DuraVent Model BV 10 and 12 Inch Large Diameter Round Rigid Pipe is a straight section of gas vent for the run above an appliance. These are the two smallest sizes in DuraVent’s large diameter range. The sections connect by matching the notches, pushing the ends together, and turning until the seams meet. Then the DuraTab locking tab presses into its slot to secure the connection. 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. Use it with an appliance listed for Type B vent.
Choose a 10 or 12 inch size, then a length of 12, 18, 24, or 36 inches. Allow for 1 inch of overlap at each joint when working out the assembled height. These rigid sections must stay uncut. An adjustable pipe fills the gap when the straight lengths do not add up to the height needed. Need a larger size? See the DuraVent Model BV 14 to 30 Inch Large Diameter Round Rigid Pipe. The DuraVent Model BV 10 and 12 Inch Large Diameter Round Rigid Pipe ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
