DuraVent Model BV Fixed Wye: joins two appliances with a 60 degree branch
The DuraVent Model BV Fixed Wye is a fitting that joins two gas appliances to one vent. Its branch enters at 60 degrees instead of a square corner, helping exhaust flow more freely than through a tee. The body and lower section each turn a full circle to line up with your furnace and water heater. Connect the larger appliance below and the smaller one to the branch. 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.
Choose from fifteen size combinations, ranging from 4 by 4 by 3 inches to 6 by 5 by 6 inches. Adjustable pipe lengths can complete the connections. If both appliances use fans to help move exhaust, both connecting pipes should be Type B. At each appliance, a draft hood connector joins the hood that collects exhaust to the vent. Single wall connecting pipe can join there, but belongs only in the open room, never through a ceiling. Need a smaller branch on a tee? See the DuraVent Model BV Reduction Tee fitting. The DuraVent Model BV Fixed Wye ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
