Single-Wall Special Gas Vent
All FasNSeal® (single-wall) vent lengths and components feature patented built-in mechanical locking band and triple-lipped directional gaskets. All pipes and components are engineered with smooth clean welds located 90° from mechanical locking bands. This construction feature allows for ease of installation. The ½” air space between the inner and outer wall on FasNSeal® W2 helps to reduce the clearance to combustibles in addition to creating a heat shield for additional safety.
FasNSeal is for use with natural gas or propane Categories II, III and IV appliances or Canada’s Type BH Gas Vent Systems, having a maximum rated operating temperature of 480°F and a maximum positive pressure of 15″ (FasNSeal Flex 6″) water column. FasNSeal can be used on a wide range of applications, including: high efficiency gas boilers, furnaces, booster heaters, pool heaters, water heaters, unit heaters, or tankless water heaters.
