FasNSeal Product Catalog

Specifications
Applications
FasNSeal and FasNSeal Flex 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
eciency gas boilers, furnaces, booster
heaters, pool heaters, water heaters, unit
heaters, or tankless water heaters.
FasNSeal W2 is ideal for use on
commercial applications such as: oce
buildings, medical facilities, condos,
or multiple unit apartment complexes
where there is the need for low
clearances to combustibles. In residential
applications, FasNSeal W2 is the perfect
solution for running between oor joists
or in walls.

FasNSeal & FasNSeal W2
All FasNSeal (single-wall) and FasNSeal W2 (double-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.
All FasNSeal components which come in contact with exhaust
gases and condensates are now silicone free. This important design
and manufacturing feature greatly reduces the chances of system
breakdown and failure. The main problems with silicone are there
are too many adhesion factors which are very dicult to control
and the process of binding similar materials with an epoxy, which
can weaken the bond over time. Welded seams ensure a leak-free
product that is meant to last.
FasNSeal Flex
Made from super-ferritic stainless steel. Corrosion resistant.
Manufactured with a sure-seal locking seam for superior strength
and exibility. The smooth inner-wall provides for no output
reduction, allowing for full appliance eciency, ease of cleaning
and regular maintenance. The smooth inner wall optimizes
gas ow, minimizes back pressure, and facilitates condensate
management. Flexible chimney liner is listed to UL 1738 standard.
