Novavent Z-Flex Z Vent CAT 3 - 4 Inch Venting Pipe
NovaFlex Novavent is designed for use with boilers, high efficiency gas and oil heaters and water heaters where cool flue gases are vented under pressure. Novavent in 4 Inch contains a built-in, fail-safe gasket and locking band connection. No sealant is required.
Novavent Z Flex is the perfect Venting choice for the Gas Tankless Water Heaters and Gas Boilers that require 4" CAT III / Catergory 3 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!
