Centrotherm ISVL032UV-16 Vent Length 3 in X 24 in Single Wall

Product Description

The CENTROTHERM ISVL032UV-16 is a single-wall polypropylene vent length designed for high-efficiency condensing appliance venting systems. Part of the InnoFlue lineup, this 3-inch diameter by 24-inch vent length is constructed from UL1738 and ULCS636 listed polypropylene and is engineered to handle flue gas temperatures up to 230 degrees F. The long-socket end connection integrates a factory-installed gasket that creates an airtight seal without glues, primers, or solvents, reducing installation time and eliminating solvent-fume exposure on the job. Thin-wall construction keeps the component lightweight without compromising structural integrity or thermal performance.

This vent length is suited for residential and light-commercial installations using high-efficiency condensing furnaces, boilers, and water heaters that require a Category IV venting solution. The PPs-UV black designation indicates UV-resistant polypropylene material, making it appropriate for runs that may be exposed to sunlight. Installers working with InnoFlue systems will find this 24-inch segment useful for precise vent-run layout where shorter sections are needed to complete a run or navigate around framing and mechanical obstacles.

Key Features

• Evaluated to UL1738 and ULCS636 by ICC for Category IV venting applications
• Rated for flue gas temperatures up to 230 degrees F (110 degrees C)
• Integrated gasket provides an airtight seal with no glues, primers, or solvents required
• UV-resistant PPs-UV black polypropylene construction for exposed-run installations
• Single-wall, thin-wall design reduces weight and simplifies handling during installation
• Long-socket end configuration for secure, leak-free pipe-to-pipe connection

Compatibility

Designed as an OEM-style component for use within the InnoFlue single-wall polypropylene venting system in 3-inch diameter configurations.

Installation Notes

Installation should be performed by a licensed HVAC technician or plumber familiar with Category IV venting requirements and the applicable fuel-gas or mechanical code in the jurisdiction. Shut down and de-energize the appliance before making any vent connections or modifications. No primers, glues, or solvents are required; rely on the integrated gasket and proper socket seating for a sealed joint. Follow the appliance manufacturer's venting instructions and local code requirements for support spacing, termination clearances, and penetration fire-stopping.
