The Hart & Cooley 4RP4 is a high-quality, factory-built Type B round gas vent pipe designed for use with flue systems that operate under negative pressure. It features a 4 inch inner diameter, approx. 4-1/2″ outer diameter, and is 4 feet long. Its construction includes a 0.012″ aluminum inner wall and 0.018″ G90 galvanized steel outer wall for durability and corrosion resistance. This double-wall, air-insulated B-Vent pipe uses a unique locking band and positive-stop joint design to ensure secure connection, allowing full 360° rotation for ease of installation.  The minimum clearance to combustibles is just 1″ when installed correctly. It is suitable for gas-fired Category I appliances where flue gas temperatures do not exceed about 400 °F above ambient.  Use this component as part of a proper venting system for natural-gas heating appliances; note it is not rated for oil, multi-fuel, or incinerator applications.
