Centrotherm 250400202320 Innoflue Vent Length 4x120 in

Product Description

The CENTROTHERM 250400202320 is an InnoFlue vent length section designed for use in concentric or single-pipe polypropylene venting systems. Measuring 4 inches in diameter and 120 inches in length, this straight vent section connects appliance flue outlets to terminal fittings in condensing gas appliance installations. Licensed HVAC technicians and plumbers install this component as part of a complete InnoFlue venting system. The 10-foot run length makes it well suited for longer straight venting runs where multiple short sections would otherwise be required. The part weighs 6.28 pounds and is manufactured under the Centrotherm InnoFlue product line.

This vent length section is used in residential and light commercial applications where condensing furnaces, boilers, or water heaters require polypropylene vent pipe. It is appropriate for systems that need a Category IV or condensing appliance vent path. Installations typically involve direct vent or single-pipe configurations routed through interior walls, floor assemblies, or mechanical rooms. The 4-inch diameter size serves mid-range input appliances common in residential heating systems.

Key Features

• 4-inch diameter fits mid-range residential condensing appliance venting requirements

Compatibility

Installation Notes

This vent section must be installed by a qualified HVAC technician or plumber in accordance with local mechanical codes and the appliance manufacturer venting instructions.
