B-Vent Wall Thimble

Additional B-Vent Info:

DuraVent's Type B Gas Vent system features the innovative DuraLock technology, ensuring a secure connection. With alignment indicators, you can easily see the parts line up, feel the firm connection as the ends grip together, and hear the distinct snap when it locks in place. Designed to withstand the tough conditions of job sites, the inner wall is recessed to prevent damage during handling. Type B Gas Vent is engineered for quick heat-up and remains hot during appliance operation, minimizing condensation in both the appliance and vent system. Available in lengths from 6 to 60 inches, the system includes a wide range of adjustable and rigid fittings. Note that Type B gas vents are not suitable for use with wood-burning or coal applications, industrial ovens, exhaust ranges and hoods, grease or pollution ducting, or as free-standing exhaust vents for high-temperature environments.
Use for through-the-wall system to provide clearances for vent from combustibles. Adjusts from 3½” to 6” to accommodate various wall thicknesses. Larger diameter wall thimbles are field-fabricated. (See local codes for guidelines.)
