There are several distinct advantages with the Z-Dens Concentric horizontal and vertical vent kits. This polypropylene piping is long lasting and easy to install as no cure time is required. Acidic flue gas condensate resistance provides a means of reducing boiler contamination. Lastly, in the event of expansion and contraction of the venting run, the Z-Flex Z-Dens venting eliminates the inherent dangers found with PVC/CPVC glued pipe joints.
