DuraVent Model BV DuraConnect I Single Wall Expandable Flexible Gas Vent Connector: one flexible piece from appliance to vent
The DuraVent Model BV DuraConnect I Single Wall Expandable Flexible Gas Vent Connector is a single wall connector between the appliance and vent. It stretches from the draft hood, the fitting at the appliance’s exhaust outlet, to the double wall vent. That one piece replaces a separate hood connector, short pipe, and elbows. 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 use natural draft, meaning warm exhaust rises on its own.
Choose a 3 or 4 inch size, then a length range: 2 to 3 1/2 feet or 2 1/2 to 5 feet. This connector stays in the open room, never enclosed or routed through a ceiling, wall, attic, or crawl space. Need the double wall version? See the DuraVent Model BV DuraConnect II Double Wall Flex Connector. The DuraVent Model BV DuraConnect I Single Wall Expandable Flexible Gas Vent Connector ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
