FasNSeal W2 Special Gas Vent System for Category II, III & IV Heating Appliances
Sets the standard yet again as the first AL29-4C Double Wall Vent System with a built-in gasket, a
mechanical locking band and featuring a full " air space for superior performance. Available in 3" through 24" diameters, Commercial and Industrial.
FasNSeal®W2 System is FULLY
INTERCHANGEABLE with our FasNSeal® Single-wall System
Material Selection & Design
The FasNSeal®W2 Double Wall Special Gas Vent System
is manufactured under the most stringent quality control measures utilizing the latest production technology
and know-how. FasNSeal®W2 is ideally suited for exhausting high efficiency; natural gas or propane
fired heating equipment, where low flue gas temperatures can result in significant condensate formation
within the vent system.
The flue gas conduit (inner tube) is made from AL29-4C or 29-4 (S44735), a superferritic stainless steel
designed for extreme resistance to chloride ion pitting, crevice corrosion and stress corrosion cracking, as
well as general corrosion in oxidizing and moderately reducing environments. AL29-4C is an ideal choice
for resisting deleterious effects of corrosive condensates created by partially or fully condensing natural
gas and propane fired heating appliances. The Canadian Gas Research Institute confirmed that test
results proved AL29-4C to be one of two "most corrosion resistant alloys of twenty candidate stainless
steels evaluated for resistance to chloride-induced corrosion in condensing and partially condensing
gas-fired appliances". AL29-4C is a registered trademark of Allegheny Ludlum Corp.

The Jacket (outer tube) is manufactured from type 304 or type 430 stainless steel to provide long lasting
performance and stability inside a building or when exposed to the outdoors.
The Air space between the flue gas conduit and jacket is .5 inches, providing close clearances to
combustibles, reasonable outside dimensions and an additional heat shield or margin of safety where
needed.
FasNSeal®W2 has been tested and is listed by Underwriters
Laboratories, Inc. to UL 1738 and ULC-S636-95 safety standards. When installed according to ProTech
Systems installation instructions, FasNSeal®W2 meets all test requirements for horizontal and
vertical; interior or exterior installation.

FasNSeal®W2 Is Built For Performance
Proven in our single wall system since 1997, all FasNSeal® products feature a smooth weld seam
inside and out that is completely shielded during the TIG welding process. Contamination or molecular
changes in the weld seam are avoided; no fillers are used in the welding process. Tube ends are formed
under the most stringent quality standards to guarantee a perfect fit every time and to avoid built-in stress
points or weak areas.

FasNSeal®W2 Applications
FasNSeal®W2 is a Special Gas Vent and Gas Vent Connector, designed for use on natural gas or
propane-fired appliances listed as Category II, III and IV or in Canada Type BH Gas Vent Systems having
a maximum operating temperature of 480 degrees F and maximum rated positive pressure of 6" water
column (tested at 15" water column! ). FasNSeal®W2 provides venting for high efficiency gas boilers,
furnaces, booster heaters, pool heaters, water heaters, unit heaters or tankless water heaters and is
available in 3" -10", 12", 14" and 16" nominal flue gas conduit diameters. FasNSeal®W2 may also be
used as a vent for Category I, natural gas or propane-fired heaters. (See installation instructions for
details). FasNSeal®W2 must be sized according to the heating appliance manufacturers instructions,
NFPA 211, NFPA 54, The National Fuel Gas Code ANSI Z223.1 and any other relevant local building
codes and regulations (see installation instructions for details!).

FasNSeal® W2 Features Built-in Gaskets and Mechanical Locking Bands
The flue gas conduit of every vent length and component (inner tube) features a built-in gasket in its
female-end to seal each joint. An integrated mechanical locking band is factory-built into the jacket (outer
tube) of each vent length and component (Pat #6,026,803 additional. Patents pending). FasNSeal®W2
parts are simply pushed together until fully seated. This renders the joints air and water- tight. By tightening
their integrated mechanical locking band, parts are fastened together in seconds. FasNSeal®W2 can
be taken apart and reassembled in minutes, making inspection, maintenance or re-routing of
FasNSeal®W2 systems a breeze.

Adjustable
Vent Lengths
featured in our Wall Thimbles allow for built-in horizontal adjustability without the
need for cutting pipe. Our standard Adjustable Vent Length allows 4" to 12" of vertical adjustment, making
pitching FasNSeal®W2 to properly drain condensate simple. Connecting FasNSeal®W2 to a
heater is done efficiently with one of our many Adaptors approved by heating appliance manufacturers.
Heating equipment can be fired up immediately upon completing a FasNSeal®W2 installation, as no
cure time or cleanup is required. PTS listened to the installer and came up with the perfect way to join
FasNSeal® parts. No cutting, no exterior clamps, no joints to wipe with alcohol, no rings, no tabs, no
mess to clean.
