DuraVent Model BV Round Rigid Pipe: straight sections for the main vent run
The DuraVent Model BV Round Rigid Pipe is a straight length of double wall gas vent. These sections form most of the vent run, pushing together end to end toward the roof. An aluminum inner pipe sits inside a galvanized steel outer pipe. Air between the walls keeps the inside hot so exhaust rises well while the outside stays cooler. 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 appliances approved for Type B vent.
Choose a 3, 4, 5, or 6 inch diameter, select whether installation is in Canada, then pick a length from 6 to 60 inches. The Canada version has a galvalume outer pipe. Each DuraLock joint pushes together until seated, then a thumb press on the DuraTab secures it in place of a screw. Allow for 1 1/2 inches taken up at each joint. Use adjustable pipe for the remaining gap rather than cutting rigid pipe. Need a larger diameter? See the DuraVent Model BV 7 and 8 Inch Round Rigid Pipe. The DuraVent Model BV Round Rigid Pipe ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
