Z-flex ZF-2SVSTTF03 Z-vent Tee Termination 3 Inches

Product Description

The Z-FLEX ZF-2SVSTTF03 is a tee termination fitting designed for use with Z-Vent single-wall stainless steel venting systems. This fitting provides a tee-style exhaust and combustion air inlet point at the termination of a direct-vent appliance installation. The tee configuration allows exhaust gases to exit vertically while drawing combustion air from the surrounding atmosphere, making it a critical component in properly terminating a venting run. At 3 inches in diameter and weighing under 1 pound, it is compact and straightforward to handle during installation. Licensed HVAC technicians and plumbers install this fitting as part of compliant venting assemblies on gas-fired appliances.

This tee termination is suited for residential and light commercial applications where a 3-inch Z-Vent single-wall venting system terminates through a sidewall or other approved surface. It is typically used with Category II, Category III, or Category IV gas appliances such as condensing boilers, water heaters, and furnaces that require stainless steel vent systems. The fitting mates with compatible Z-Vent 3-inch single-wall components and is installed at the final point of the vent run.

Key Features

Compatibility

Designed as an OEM-style termination fitting for use with Z-Vent 3-inch single-wall stainless steel venting systems on compatible gas-fired appliances.

Installation Notes

Installation should be performed by a licensed HVAC technician or plumber in accordance with the appliance manufacturer instructions, local mechanical codes, and the International Fuel Gas Code (IFGC). Shut off the gas supply and allow the appliance to cool completely before beginning any venting work. Ensure the termination location meets minimum clearance requirements from windows, doors, gas meters, and electrical intakes as required by code. Do not operate the appliance until all venting connections are verified secure and leak-free.
