DuraVent Model BV Universal Male Adapter: continue another brand’s vent upward toward the cap
The DuraVent Model BV Universal Male Adapter is a fitting that connects another brand’s Type B vent to Model BV pipe. It fits over the upper end of the existing pipe so Model BV can carry on toward the roof 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. Choose a diameter from 3 to 8 inches on this page. The adapter needs at least 1 1/2 inches of overlap. Two supplied short screws secure it through holes drilled in the outer wall only.
You do not need this adapter for every brand. Round Model BV connects directly to Selkirk, Hart and Cooley, AirMate, and two other makers’ Type B pipe. Other brands need the male or female adapter. Model BV also has oval versions for stud walls and 10 to 30 inch versions for larger equipment, sold separately. Connecting at the lower end instead? See the DuraVent Model BV Universal Female Adapter for bottom connections. The DuraVent Model BV Universal Male Adapter ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
