DuraVent Model BV Tee Cap: closes the tee and comes off for a look inside
The DuraVent Model BV Tee Cap is a removable cover for the bottom opening of a Model BV tee. It closes that opening to keep air from leaking into the vent. You can take it off again when you need to look inside. DuraVent requires this cap when a tee forms the base of a vertical vent run. 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 the diameter to match your tee, from 3 to 30 inch. Sizes from 10 to 30 inch belong to the large diameter line.
Model BV pipe has aluminum inside and galvanized steel outside. The air gap between them keeps the inner pipe hot to help exhaust flow upward while keeping the outside cool. The inner pipe attaches to the outer pipe at just one end, letting it expand and contract quietly. Need the tee this cap closes? See the DuraVent Model BV Standard Tee. The DuraVent Model BV Tee Cap ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
