DuraVent Model BV Adjustable Reduction Tee: connects an 8 inch run to a 10 inch vent
The DuraVent Model BV Adjustable Reduction Tee is a tee that connects an 8 inch appliance vent to a 10 inch vertical vent. Its smaller side branch brings the two sizes together and turns the exhaust path from sideways to up. 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. DuraVent makes this fitting in just this size combination. It connects to the larger Model BV line, which runs from 10 to 30 inch for big boilers, furnaces, and commercial and rooftop equipment.
The 8 inch pipe slips into the side branch, giving 3 inches of adjustment to help position the connection. Three included screws hold it in place through holes already in the branch. The larger vent still needs a 1 inch gap from wood framing and other materials that can burn in the USA. Need the same size at every opening? See the DuraVent Model BV Large Diameter Standard Tee. The DuraVent Model BV Adjustable Reduction Tee ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
