Centrotherm icel3545 Innoflue Concentric Elbow 45 Degree 3 or 5 Inch Id X 5.5 Inch Od Aluminum Polypropylene

Product Description

The Centrotherm icel3545 InnoFlue Concentric Elbow is a 45-degree directional fitting designed for use with InnoFlue polypropylene vent systems. It is made for HVAC professionals who install and service high-efficiency condensing boilers, furnaces, and water heaters that require polypropylene venting. This elbow allows installers to change the direction of a concentric vent run at a 45-degree angle, giving greater flexibility when routing flue and combustion air piping through tight spaces or around structural obstacles. The concentric design means the exhaust flue pipe and the combustion air intake pipe are routed together within a single assembly, simplifying installation and reducing the number of penetrations through walls or roofs. The icel3545 features an inner diameter of 3 inches or 5 inches and an outer diameter of 5.5 inches, making it compatible with the standard concentric pipe sizes used across the InnoFlue product line. It is constructed from a combination of aluminum and polypropylene, materials chosen for their resistance to the acidic condensate produced by condensing appliances. Polypropylene venting is widely specified for Category IV appliances because it withstands flue gas temperatures and corrosive moisture that would damage PVC or metal vent systems. The white finish blends cleanly into residential and light commercial mechanical spaces. This fitting is domestically produced and carries the quality standards expected from the InnoFlue system, which is a recognized name among HVAC contractors for condensing appliance venting. Installers working with InnoFlue SW, InnoFlue Flex, or other InnoFlue polypropylene components will find this elbow integrates directly into existing system configurations. The 45-degree angle provides a more gradual directional change than a 90-degree elbow, which can help maintain proper flue gas velocity and reduce resistance in the vent run. Proper elbow selection is critical for system efficiency and code compliance on high-efficiency heating equipment.
