The air insulated double wall construction reduces outer 
wall surface temperatures clearance to combustibles and 
adds thermal resistance to help maintain stack temperature. 
The outer wall is fabricated from Type 304 Stainless Steel, 
providing long lasting performance and superior structural 
integrity. 
Optional 316L Stainless Steel is available where the vent 
is installed in potentially corrosive environments; such as 
rooms with chemicals present, providing increased corrosion 
resistance to the outer casing. 
Fusion welded components provide superior fit, reduced 
turbulence and flow resistance. Also eliminated are crevices 
and other spots where condensation can collect and corrode 
the vent. 
Pipe and fittings ends are precision formed by specially 
designed high tolerance tooling. All seams are continuously 
welded using proprietary Z-Weld technology providing long 
service life and a virtual air and water tight construction.
