- Long lasting and easy to install, no cure time required.
- Resistant to acidic flue gas condensate reducing boiler contamination.
- In the event of expansion and contraction of the venting run, Z-DENS eliminates the inherent dangers found with PVC/ CPVC glued pipe joints.
- Special ingredients in the material composition of Z-DENS ensure a fire retardant system and therefore is safer to use than other standard polymeric flue gas venting systems.
All polypropylene material, including PPs, expands and contracts with temperature change. To ensure that the installation initially is and remains completely flue gas tight, it is necessary that the Z-DENS bracket is used. For the correct installation of the bracket, follow the instructions in the installation manual. Exclusive use of Z-DENS lubricant when installing Z-DENS PPs, ensures that a reliable and safe connection is guaranteed.
During the production of PPs flue gas systems less CO2 is produced than with the production of traditional metal flue gas systems. *UV stabilized parts available.
Greater efficiencies and a more aesthetically pleasing presence can also be achieved by using Z-DENS as the fresh air inlet.
