DuraVent Model BV 10 and 12 Inch Universal Male Adapter: continue an existing vent toward the cap
The DuraVent Model BV 10 and 12 Inch Universal Male Adapter is a fitting that connects an existing Type B vent to Model BV above it. It fits over the older pipe’s male end, giving you a Model BV connection for the run toward the cap. 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’s catalog allows connections to existing vent from other brands. Its installation instructions specifically describe a connection to DuraVent’s older Model GV pipe.
Choose 10 or 12 inch to match your vent. For Model GV, the adapter seats fully over the pipe end and fastens through pilot holes with three included screws. Model BV sections in these sizes join by matching the notches, pushing together, and turning until the seams meet. Then press the locking tab into its slot. Allow for 1 inch of length lost at each joint. Starting at the appliance instead? See the DuraVent Model BV Large Diameter Draft Hood Connector. The DuraVent Model BV 10 and 12 Inch Universal Male Adapter ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
