Centrotherm ISELS0387UV-12 3in 87deg Pps-uv Vent Elbow

Product Description

The CENTROTHERM ISELS0387UV-12 is a single-wall 87-degree elbow fitting for polypropylene (PPs-UV) venting systems. Manufactured with UV-stabilized black polypropylene, this elbow is designed to manage directional changes in direct-vent and Category IV appliance vent runs. The long-socket design accepts standard InnoFlue pipe ends and seals with an integrated EPDM gasket, eliminating the need for glues, primers, or solvents during installation. At 3 inches in diameter, this fitting suits residential and light commercial gas appliance venting where a near-horizontal 87-degree offset is required. HVAC technicians and plumbers install this fitting as part of a complete polypropylene vent system.

This elbow is suited for venting condensing gas furnaces, boilers, water heaters, and other Category IV appliances that require corrosion-resistant polypropylene flue pipe. The 87-degree angle accommodates tight directional changes in vent layouts where straight horizontal or vertical runs require redirection. The UV-stabilized PPs-UV material makes this fitting appropriate for exposed outdoor vent runs in addition to interior applications. Installation does not require adhesives, making field assembly faster and reducing potential for improper cementing procedures.

Installation Notes

Installation of polypropylene vent fittings is typically performed by a licensed HVAC technician or plumber in accordance with the appliance manufacturer instructions and local mechanical codes referencing IFGC or IMC standards. Power down and isolate the appliance before servicing any vent connections. Verify that pipe ends are clean and free of debris before engaging the long socket, and confirm the EPDM gasket is properly seated before applying load to the fitting. Do not use pipe dope, cement, or solvent-based primers on PPs-UV fittings.
