The Z-FLEX ZF-2SVEDWCF03 is a horizontal condensation drain pipe designed for use with Z-Vent venting systems on high-efficiency, condensing appliances. This fitting manages condensate runoff produced during the combustion process in condensing furnaces, boilers, and water heaters, directing moisture away from the appliance and vent system. Weighing under 1 pound at 0.99 pounds, it is a lightweight component sized at 3 inches to match standard Z-Vent vent pipe diameters. Licensed HVAC technicians and plumbers typically install this fitting as part of a complete venting assembly on new installations or system retrofits.
This condensation drain pipe is suited for horizontal vent runs on residential and light commercial condensing appliances. It is used where the vent system requires a dedicated condensate drainage point along a horizontal section. The 3-inch diameter fits within Z-Vent single-wall stainless steel vent systems commonly installed on Category IV appliances, which produce acidic condensate that must be managed and drained properly to protect the vent system and appliance.
Designed as an OEM-style component for use within Z-Flex Z-Vent 3-inch single-wall venting systems on Category IV condensing appliances including high-efficiency furnaces, boilers, and water heaters.
Installation should be performed by a licensed HVAC technician or plumber in accordance with the appliance manufacturer instructions and local mechanical codes. Shut down and de-energize the appliance before beginning any work on the vent system. Ensure the condensate drain line connected to this fitting is properly pitched and routed to an approved drain point. Verify all vent joints are sealed per the Z-Vent system requirements to prevent flue gas or condensate leakage.
