Rugged Construction
Strong, durable galvanized steel outer pipe has internal spacing beads to assure a uniform insulating air space between pipe walls. Each end is die-formed to assure uniform sizing for strong, easy-to-connect joints. In Canada, some lengths are available in galvalume steel outer pipe. 

Assured Safety
The double wall (pipe within a pipe) construction with its built-in air space, provides permanent insulation and keeps the inner pipe hot and the outer pipe relatively cool. This construction creates quick, strong vent action reducing condensation in the pipe and overheating of nearby enclosure surfaces.

DuraVent Model BV and BVO Type B Gas Vent have been tested and listed per UL 441 for installation as Type B and BW gas vents. These can be installed in single and multi-story buildings in accordance with the standards of NFPA 54 and NFPA 211.
