Centrotherm icrt2439 Innoflue Concentric Roof Termination 2 or 4 Inch Vent Polypropylene

Product Description

The Centrotherm ICRT2439 is a concentric roof termination designed for use with the InnoFlue venting system. It combines flue gas exhaust and combustion air intake into a single roof penetration point. This two-in-one design reduces the number of roof openings required during installation, which saves time and simplifies the job for HVAC technicians working on high-efficiency condensing appliances. The unit is built from polypropylene, a material well suited for handling the acidic condensate produced by condensing boilers and furnaces. Polypropylene resists corrosion and holds up against the thermal cycling that venting systems experience during daily operation. The ICRT2439 is finished in black and is designed for use with 2 inch or 4 inch vent configurations, giving installers flexibility across a range of equipment sizes. It is a domestically sourced product and is compatible with InnoFlue concentric systems as well as InnoFlue SW systems when paired with an ICTC adapter. Concentric roof terminations like this one are a standard solution for installations where side-wall termination is not possible or not permitted by local code. They are commonly used with condensing gas furnaces, condensing boilers, and other sealed-combustion appliances that require direct vent configurations. The roof termination cap is engineered to prevent rain, debris, and pests from entering the vent system while allowing proper exhaust flow. Proper termination is critical to system efficiency and safe appliance operation. HVAC professionals working with InnoFlue polypropylene venting systems will find this termination fitting to be a reliable, code-compliant solution for rooftop applications.
