Centrotherm iaspp03-20 Bird Screen 3 Inch Single Wall

Product Description

The CENTROTHERM iaspp03-20 is a single-wall bird screen designed to protect polypropylene exhaust vent terminations from pest intrusion, debris, and foreign objects. Part of the InnoFlue product line, it is constructed from UV-stabilized black polypropylene and is evaluated to UL1738 and ULCS636 standards by ICC. The screen installs without glues, primers, or solvents, making it a fast and clean addition to any exhaust termination. It is sized for 3-inch single-wall vent pipe and fits within the InnoFlue exhaust system family. Licensed technicians and qualified installers working on direct-vent or Category IV appliance exhaust systems are the primary end users for this component.

This bird screen is suited for residential and light commercial applications where polypropylene single-wall exhaust pipe is used to terminate condensing appliances such as high-efficiency furnaces or boilers. It seats at the exhaust termination point, providing a low-profile barrier that does not restrict exhaust flow while blocking entry of birds, rodents, and airborne debris. The design is intended to complement InnoFlue single-wall exhaust vent runs terminating outdoors.

Installation Notes

Installation is performed by a licensed HVAC technician or qualified vent system installer. Shut down and de-energize the appliance before servicing the exhaust termination. No adhesives or solvents are required; follow the InnoFlue system installation instructions for proper seating and orientation.
