Centrotherm 250407203200 Wall Termination 4 Inches

Product Description

The CENTROTHERM 250407203200 is a gasketed polypropylene low profile wall termination designed for direct-vent and positive-pressure flue systems. Rated for continuous exposure up to 230 degrees F, this termination cap handles the corrosive condensate and elevated flue temperatures common in high-efficiency gas appliance installations. The polypropylene construction resists chemical degradation from acidic condensate, making it a reliable choice for condensing furnace and boiler venting applications. A licensed HVAC technician or plumber installs this component as part of a certified venting system. It fits 4-inch vent pipe and mounts flush against an exterior wall surface.

This wall termination is used in residential and light commercial installations where a low-profile exterior wall exit is required for polypropylene vent systems. It is suited for condensing gas furnaces, boilers, and other high-efficiency appliances that require Category IV or positive-pressure plastic venting routed horizontally through an exterior wall. The gasketed design helps maintain a sealed connection at the wall penetration point. It also functions as the termination point for the CENTROTHERM ISLPT0404 vent system.
