Special Gas Vent System for Category II, III & IV Heating Appliances NEW FasNSeal Flex: The only UL 1738 listed high-efficiency Flexible Vent Component. Click here for more information. Set the standard in 1997 as the first vent system with a built-in gasket and locking band. FasNSeal is designed for high efficiency gas heaters where cool flue gases are vented under pressure. Available in 3" through 24" diameters. FasNSeal has an advanced design that offers the most professional venting method for high efficiency gas heaters. It is unparalleled in its ease of installation, precision fit and performance. With FasNSeal you get a simple, gas and water-tight system that safely guides poisonous flue gases - including carbon monoxide - away from the heat source and out of your customer's home. NO SILICONE is needed to install the FasNSeal Vent System for Category II, III & IV Heating Appliances.
Each vent length and component features a built-in mechanical locking band and gasket. Parts are simply pushed together to a stop bead, which renders the joints air and water-tight. By tightening their integrated mechanical locking band, parts are fastened together in seconds. FasNSeal can be taken apart and reassembled in minutes, making inspection, maintenance or rerouting of FasNSeal systems a breeze. Should a part or gasket ever become damaged, replacement takes less than five minutes and the integrity of the system is not compromised! FasNSeal has been tested and is listed by Underwriters Laboratories, Inc. to UL 1738 and ULC-S636-95. ProTech Systems own experience with AL29-4C dates back to 1986, when VENTINOXVG for gas appliances was introduced as the first chimney lining system made from this alloy. VENTINOX provides safe venting in thousands of American homes today and features a lifetime warranty. Material Selection and Experience Counts FasNSeal is manufactured from AL29-4C, 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 found 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.
FasNSeal may also be used as a vent for Category I, natural gas or propane-fired heaters. FasNSeal must be sized according to the heating appliance manufacturers instructions, NFPA 211, NFPA 54 and any other relevant local building codes and regulations (see installation instructions for details!) Built-in Gaskets and Mechanical Locking Bands Each vent length and component features a built-in mechanical locking band and gasket. Parts are simply pushed together to a stop bead, which renders the joints air and water-tight. By tightening the integrated mechanical locking band, parts are fastened together in seconds. FasNSeal can be taken apart and reassembled in minutes, making inspection, maintenance or rerouting of FasNSeal systems a breeze. Should a part or gasket ever become damaged, replacement takes less than five minutes and the integrity of the system is not compromised!
FasNSeal 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.
