Two special gas venting systems, Model SW single-wall vents and Model CV concentric vents, are available through a partnership between the company and its sister company Heat-fab, a division of Selkirk. The units are made of AL29-4C® stainless steel for corrosion resistance, and are backed by a 10-year warranty. Gaskets are integrated; they cannot become loose or get lost. According to the manufacturer, precision laser-welded butt seams ensure tight, leak-proof installation. Model SW is available in 3- to 16-inch diameters. It has a Ring and Tab™ locking assembly. Model CV is a sealed combustion vent. It is available in 3-inch (5-inch inch intake) and 4-inch (7-inch intake) sizes. Common applications include zero-clearance, double-wall, and concentric venting.
