“a venting system shall
be made of corrosion
resistant materials…”
(ul 1738 section 5.3)
“stainless steel…and other
vent gas conduit shall comply
with the requirements for the
applicable tests…”
(ul 1738 section 5.4)
Both AL29-4C and 444
have passed the UL 1738
Corrosion tests.
Codes and Standards only
require a vent system
that has been listed to UL
1738. No specific material
requirement. UL1738 does
not state that material must
be AL29-4C.
444 has a higher useful
temperature limit (more
applications).
444 has the equivalent
corrosion resistance as
AL29-4C, but at less cost.

Specifications
fasnseal
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 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.
All FasNSeal single- and double-wall vent lengths and components
feature patented built-in mechanical locking band and triplelipped 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.
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 difficult to control and the process of
binding similar materials with an epoxy, which can weaken the
bond over time. Welded seams ensures a leak-free product that is
meant to last.
fasnseal W2 is ideal for use on
commercial applications such as: office
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 floor joists
or in walls.
