IPEX USA products here are FGV low-profile termination kits in 2-inch and 3-inch PVC, listed to UL 1738. These kits terminate the intake and exhaust of high-efficiency gas appliances such as condensing boilers and water heaters through a sidewall.
Choose the kit size to match the appliance vent diameter, and confirm the appliance manufacturer approves this termination and PVC venting system. Check required clearances to windows, doors, grade and other openings, and verify that all pipe, fittings and cement used in the vent run are part of a UL 1738 listed system.
