Novavent Z Flex is the perfect Venting choice for the Gas Tankless Water Heaters and Gas Boilers that require 4" CAT III Stainless Steel Venting. When compared to plastic and other resin based materials used for venting systems, NovaVENT displays considerably lower thermal expansion and contraction making it much more resistance to stress corrosion cracking.
Novavent Z Flex has wall thimbles, vent terminators, straight vent lengths, elbows and more. We also have accessories such as drain tube kits and sealant. Will work for any other Category II, III and IV gas heating appliance too!
Z Flex Novavent vent pieces will work with Z Flex Z-Vent venting. Novavent is a less expensive alternative to Z-Vent and is also manufactured by Z-Flex which has over 30 years of proven reliability. Novavent has a thinner gauge metal than Z-Vent but still meets all applicable national building and fire codes and is UL listed 1738 for Category II,III, IV gas appliances. Novavent has wall thimbles, vent terminators, straight vent lengths, elbows and multiple adjustable lengths available.
