Centrotherm ISVL041-9 Single Wall Vent Length 4 X 12 Inches

Product Description

The CENTROTHERM ISVL041-9 is a single wall polypropylene vent length designed for high-efficiency condensing appliance venting systems. Measuring 4 inches in diameter and 12 inches in length, this component integrates directly into the InnoFlue venting system without the need for glues, primers, or solvents. Constructed from polypropylene listed to UL1738 and ULCS636 as evaluated by ICC, it withstands flue gas temperatures up to 230 degrees F (110 degrees C). The long socket design creates a secure, airtight connection via an integrated gasket, making installation straightforward for licensed HVAC technicians working on condensing furnaces, boilers, and water heaters.

This vent length is suited for residential and light commercial venting applications where high-efficiency condensing appliances require a listed polypropylene flue system. The thin-wall, lightweight construction simplifies handling and reduces installation time in tight mechanical spaces. Its long socket end allows for a reliable, gasket-sealed joint that eliminates the mess and cure time associated with solvent-based joining methods, making it a practical choice for both new installations and retrofit projects on condensing appliances.

Installation Notes

Installation should be performed by a licensed HVAC technician in accordance with the appliance manufacturer instructions and applicable mechanical codes such as the IFGC. Power down and shut off the appliance before servicing or modifying any flue venting components. No adhesives or solvents are required for joint assembly; rely on the integrated gasket and proper socket engagement to achieve a sealed connection. Inspect the gasket for damage before assembly to ensure a leak-free installation.
