Centrotherm iafc03 Innoflue Flue Clamp 3 Inches Stainless Steel for Polypropylene Vent Systems

Product Description

The Centrotherm IAFC03 is a stainless steel flue clamp designed for use with InnoFlue polypropylene vent systems. It fits 3-inch nominal diameter vent pipe and provides a secure, leak-resistant connection between vent sections. HVAC technicians and installers rely on this type of clamp to maintain the structural integrity of a condensing appliance exhaust system. A failed or loose flue connection can allow combustion gases to escape into living spaces, making a reliable clamp an essential component of any safe vent installation.

InnoFlue polypropylene vent systems are commonly used with high-efficiency condensing boilers, furnaces, and water heaters. These appliances produce low-temperature, acidic condensate in the flue gas, which can degrade standard metal vent materials over time. Polypropylene vent pipe resists this acidic condensate, and the IAFC03 clamp is built to work in the same demanding environment. Stainless steel construction gives the clamp corrosion resistance and long service life, even when exposed to moisture and exhaust gases.

The clamp measures 4.3 inches inner diameter and 1 inch in height, giving installers a precise fit around the 3-inch nominal pipe. The compact height keeps the footprint tight in confined mechanical rooms and utility spaces. This is a domestically sourced component, suitable for new installations and replacement service work on existing InnoFlue vent runs. Whether running vertical stacks or horizontal terminations, this clamp helps complete a code-compliant, gas-tight vent assembly.

• Stainless steel construction resists corrosion from acidic condensate and exhaust moisture
