American Metal Products Group has partnered with its sister company, Heat-Fab, to bring to market two new special gas-venting systems. These new systems will include both Model SW single-wall vents and Model CV concentric vents. Both models are constructed with AL29-4C stainless steel for corrosion resistance. Tools are not required, due to the ring and tab locking assembly. The manufacturer says there are no external clamps to lose and gaskets are integrated and cannot come loose or get lost. Available in 3- to 16-inch diameters, the gas venting systems are backed by a 10-year warranty. Both models are also tested and listed by Underwriters Laboratories. The Model CV special gas vent is a sealed combustion vent required by many of today’s more efficient appliances. Common applications include zero-clearance, double-wall and concentric venting.
