DuraVent Model BV Large Diameter Standard Tee: a sideways connection to an upright gas vent
The DuraVent Model BV Large Diameter Standard Tee is a fitting that turns a sideways vent run upward. It also lets two or more large appliances share one vent. 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 a size from 10 to 30 inches. The open bottom gives access for inspection and cleaning. Each open end needs a tee cap, sold separately.
Supports and adjustable pipe lengths keep expansion from pushing against the tee. A split firestop support plate carries up to 30 feet of vent and closes the floor opening. An adjustable length fits directly below each supported section. At the appliance, sizes from 10 to 18 inches use a draft hood connector. Sizes from 20 to 30 inches use a 12 inch straight pipe screwed to the exhaust outlet instead. Need a smaller side connection? See the DuraVent Model BV Adjustable Reduction Tee with an 8 inch branch. The DuraVent Model BV Large Diameter Standard Tee ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
