Z-Flex Z-Dens 2" Concentric Horizontal & Vertical Vent Kits

Global Protankless Supply is now carrying the Z-Flex Z-Dens 2" Concentric Horizontal Kit (2ZDHK2) and also the Z-Dens 2" Concentric Vertical Kit (2ZDVK2).  The concentric horizontal and vertical vent kits are ULC-S636 listed polypropylene gas venting systems suitable for venting positive or negative pressure residential and commercial gas and oil fired Category II and IV condensing heating appliances with a maximum continuous flue gas temperature of 248°F (120°C).

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.
