DuraVent Model BV Standard Tee: where a sideways connector meets the upright vent
The DuraVent Model BV Standard Tee is a gas vent fitting that joins a sideways appliance connector to the upright vent. Its bottom opening gives access for checking inside and cleaning. A separate tee cap closes that opening. When the tee starts the upright run, the cap must be in place to keep incoming air from stopping the draft. 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. It serves natural gas or propane appliances approved for Type B vent that let warm exhaust rise on its own.
Choose a diameter from 3 to 8 inches to match your vent connection. Two or more approved gas appliances can share a vent, with their connectors joining at a fitting such as this tee. A metal plate or bracket can support a tee at the vent inlet. If the run follows a wall, the wall band sits just above the tee. Need to close the bottom? Add the DuraVent Model BV Tee Cap bottom closure. The DuraVent Model BV Standard Tee ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
