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.
