The CENTROTHERM ECO SYSTEMS ISEL0330 is a 3-inch 30-degree elbow designed for use in venting system installations. This fitting redirects airflow or exhaust at a 30-degree angle, allowing installers to navigate around obstructions while maintaining proper venting geometry. It is a single-unit fitting sold individually and is intended for use by licensed HVAC technicians and plumbers working on residential or light commercial venting applications. Review the manufacturer part number and size carefully before ordering to confirm fitment with the intended venting run.
This elbow is suited for venting system configurations where a moderate directional change is required without the sharper restriction of a 45-degree or 90-degree fitting. The 30-degree angle helps maintain adequate draft and minimizes turbulence within the vent stack. It is typically installed as part of a multi-fitting venting assembly in gas appliance exhaust, combustion air intake, or similar piped systems.
Designed as an OEM-style replacement or new-installation fitting for 3-inch venting system assemblies. Verify the full system specification and manufacturer part number before installation.
Installation should be performed by a licensed HVAC technician or plumber in accordance with the appliance manufacturer instructions and applicable codes such as the IFGC or IMC. Shut down and de-energize the connected appliance before beginning any venting work. Confirm all joints are properly sealed and supported per the venting system manufacturer requirements. Do not mix components from incompatible venting system brands or ratings.
