DuraVent Model BV Oval Standard Tee: a matching size branch for an in wall vent
The DuraVent Model BV Oval Standard Tee is the fitting that joins an appliance connector to the upright oval vent inside a wall. Its side branch is the same size as the main passage and accepts either single wall or double wall connector pipe. 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 tee sits on an oval tee support inside the wall. Keep 1 inch of open space around the branch where it passes through the wall.
Choose a 4, 5, or 6 inch size. Oval vent is flattened to fit inside a stud wall, often above a gas wall furnace. The 4 inch size fits a 2 by 4 wall, the 5 inch fits a 2 by 4 or 2 by 6 wall, and the 6 inch fits a 2 by 6 wall. These sizes describe equivalent round pipe flow, not the oval’s width. Need to close the bottom? Add the separately sold DuraVent Model BV Oval Tee Cap. The DuraVent Model BV Oval Standard Tee ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
