The Centrotherm ICVL242 InnoFlue Concentric Vent Length is a rigid polypropylene venting component designed for use in high-efficiency condensing appliance installations. It is part of the InnoFlue concentric venting system by Centrotherm Eco Systems, a product line built to handle both combustion air intake and exhaust flue gas in a single coaxial assembly. This makes it a practical choice for HVAC technicians and plumbers who need a clean, space-saving vent solution for condensing boilers, water heaters, and furnaces. The pipe measures 2 or 4 inches in inner diameter and 4.4 inches in outer diameter, with an overall length of 26.5 inches. The concentric design routes the flue exhaust through the inner pipe while drawing in fresh combustion air through the outer annular space, eliminating the need for two separate wall or roof penetrations. This simplifies rough-in work and reduces installation time on residential and light commercial jobs. The ICVL242 features dedicated male and female ends for secure, leak-resistant connections. The female end contains an internal gasket that creates a tight seal without the need for additional sealant. The male end can be field cut and chamfered to the desired length, giving installers flexibility when trimming to fit tight spaces or custom runs. The outer pipe is metal-reinforced for added structural integrity along the run. Made from polypropylene, this vent length resists the acidic condensate produced by high-efficiency appliances, making it suitable for long-term use in demanding venting applications. The gray and white finish is consistent with standard residential and commercial installations. Domestically produced for quality assurance.
The Centrotherm ICVL242 delivers a reliable concentric venting solution for condensing boiler and water heater installations, combining flexible field trimming with a gasketed seal system for fast, code-compliant vent runs.
