Measuring 4 inches in diameter and 36 inches in length, it is constructed from polypropylene listed to UL1738 and ULCS636 standards, evaluated by ICC. The vent length is engineered to handle flue gas temperatures up to 230 degrees F (110 degrees C), making it suitable for the exhaust demands of modern condensing furnaces, boilers, and water heaters. An integrated gasket provides an airtight seal without the need for glues, primers, or solvents, simplifying the installation process.\u003c\/p\u003e\u003cp\u003eThis vent length is used in residential and light commercial applications where a certified polypropylene venting system is required for condensing gas appliances. It is a central component of the InnoFlue vent system, connecting to compatible InnoFlue fittings, transitions, and terminations. The lightweight, thin-wall construction makes it well-suited for retrofits and new installations where routing through tight spaces or long runs is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePolypropylene construction listed to UL1738 and ULCS636, evaluated by ICC\u003c\/li\u003e\n\u003cli\u003eRated for flue gas temperatures up to 230 degrees F (110 degrees C)\u003c\/li\u003e\n\u003cli\u003eIntegrated gasket delivers an airtight seal without glues, primers, or solvents\u003c\/li\u003e\n\u003cli\u003eSingle-wall, thin-wall design keeps weight low for easier handling and installation\u003c\/li\u003e\n\u003cli\u003e36-inch length provides versatile run coverage within the InnoFlue system\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style component of the InnoFlue single-wall polypropylene venting system for use with condensing gas appliances requiring UL1738 or ULCS636 listed vent pipe.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician or plumber in accordance with the appliance manufacturer instructions and applicable mechanical codes, including the IFGC. Shut down and allow the appliance to cool completely before servicing any vent components. The integrated gasket eliminates the need for adhesives, but verify each joint is fully seated and the gasket is properly positioned before restoring power and gas. Support spacing should comply with the vent system manufacturer specifications and local code requirements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 36 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWall Type\u003c\/strong\u003e: Single Wall\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Polypropylene\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Flue Gas Temperature\u003c\/strong\u003e: 230 degrees F (110 degrees C)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertifications\u003c\/strong\u003e: UL1738 and ULCS636, evaluated by ICC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeal Method\u003c\/strong\u003e: Integrated gasket, no glues or solvents required\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: CENTROTHERM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: isvl043-9\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CENTROTHERM","offers":[{"title":"Default Title","offer_id":51468578816306,"sku":"ISVL043-9","price":83.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313946247.jpg?v=1783918120","url":"https:\/\/voomisupply.com\/products\/centrotherm-isvl043-9-4-inch-single-wall-vent-length","provider":"Voomi Supply","version":"1.0","type":"link"}
