DuraVent Model BV 14 to 30 Inch Large Diameter Round Rigid Pipe: straight sections for the nine largest vent sizes
The DuraVent Model BV 14 to 30 Inch Large Diameter Round Rigid Pipe is a straight section of gas vent for the run toward the roof. These sections join with a snap lock. Line up the seams with the label arrow pointing upward, then press around the joint until it clicks fully into place. 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. The large diameter range serves bigger boilers, furnaces, and commercial equipment listed for Type B vent.
Choose your size from 14 to 30 inches, then a 12, 18, 24, or 36 inch length. Each connection takes 1 inch off the combined length. These sections must not be cut. In the USA, leave 1 inch between the vent and anything that can burn. Canada calls for 2 inches for the 26 to 30 inch sizes. Need a smaller diameter?
