The Centrotherm ICVL241 is a rigid polypropylene concentric vent length designed for use in high-efficiency condensing appliance venting systems. This component is part of the InnoFlue product line and is built for HVAC professionals who need a reliable, code-compliant solution for coaxial flue gas and combustion air routing. The vent length features a 2 or 4 inches inner diameter and a 4.4 inches outer diameter, with an overall length of 14.5 inches. It is manufactured from polypropylene, a material well suited for the acidic condensate produced by condensing furnaces, boilers, and water heaters. Polypropylene resists corrosion, chemical degradation, and moisture, making it the preferred material for Category IV and condensing appliance venting applications. The concentric design allows flue exhaust gases to travel through the inner pipe while outside combustion air travels through the annular space between the inner and outer pipe. This coaxial arrangement simplifies installation by combining intake and exhaust into a single wall or roof penetration. The ICVL241 includes dedicated male and female ends for secure, leak-resistant connections. The female end contains an internal gasket that seals the joint without requiring additional sealant. The male end can be field cut and chamfered to the exact length needed for a precise fit in the field. This flexibility reduces material waste and speeds up installation time. The gray and white finish is consistent with other InnoFlue components for a clean, professional appearance. This product is domestically sourced and is intended for use by licensed HVAC installers and mechanical contractors working on residential or light commercial condensing equipment installations.
The Centrotherm ICVL241 concentric vent length delivers a durable, easy-to-install coaxial venting solution for condensing HVAC systems. Its field-cuttable male end and gasketed female connection make it a practical choice for professional installers.
