NovaFlex Novavent 2NVTB4, 4 inch diameter Termination Coupling, 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 2NVTB4 is the perfect venting choice for 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.
Z Flex Novavent 2NVTB4, 4 inch diameter Termination Coupling, will work with Z Flex Z-Vent 2SVSTPF04 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 appliance adapters, vent terminators, straight vent lengths, elbows and mulitple adjustable lengths available.
