Zvent ZFlex Cat III Venting


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 3 and 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 3" or 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!
Novavent Z Flex Stainless Steel Venting Features:
  • Gasketed Connections: no sealant required
  • Z-Flex Novavent Venting is interchangable with Z-Flex Z-Vent Venting
  • Highest Pressure Rating in the Industry: more than 3 times the standard
  • Fusion Welded Pipe Seams: provides an air-tight seam, smooth finish, better fit
  • 1 Inch Clearance to Combustibles (Unenclosed): can be installed with minimum clearance (subject to manufacturer suggestion)
  • The only metallic special gas vent pipe that can be cut to length on site
  • 15 year limited warranty
