The CENTROTHERM isvl036-16 is a single-wall polypropylene vent length designed for high-efficiency condensing appliance venting systems. Measuring 3 inches in diameter and 72 inches in length, this vent pipe features a long socket end that locks into adjoining sections without glues, primers, or solvents. An integrated gasket provides an airtight seal at every joint. Constructed from UL1738 and ULCS636 listed polypropylene, it is engineered to handle flue gas temperatures up to 230 degrees F. The thin-wall, lightweight construction makes handling and routing easier during installation, reducing labor time on residential and light commercial venting runs.
This vent length is used in InnoFlue single-wall venting systems serving high-efficiency condensing gas appliances such as furnaces, boilers, and water heaters that require approved polypropylene flue pipe. It is appropriate for both new construction and retrofit applications where the existing vent system is being replaced or extended. Licensed HVAC technicians and plumbers working with Category IV and condensing appliances are the primary installers of this component.
Designed as an OEM-style component for InnoFlue single-wall polypropylene venting systems used with high-efficiency condensing gas appliances requiring UL1738 or ULCS636 listed vent pipe.
Installation should be performed by a licensed HVAC technician or plumber in accordance with the appliance manufacturer instructions and applicable local mechanical codes. Shut down and allow the appliance to cool completely before servicing or extending any flue pipe run. No adhesives or primers are needed; verify the integrated gasket is seated correctly before locking each socket joint. Support spacing and termination clearances must comply with the vent system manufacturer guidelines and local authority having jurisdiction requirements.
