Hart Cooley 6et 6 Inch B-vent Double Wall Tee

Product Description

The HART COOLEY 6et is a 6-inch double wall round tee fitting designed for Type B gas vent systems. This tee connects to B-vent pipe runs and allows a branch connection, making it a standard component in venting assemblies for natural gas and propane appliances. The double wall construction maintains the air space required by B-vent system design, helping to sustain proper draft and vent temperatures throughout the run. Licensed HVAC technicians and plumbers install this fitting during new appliance venting installations and vent system repairs or extensions.

The 6et is sized for 6-inch B-vent systems and is suited for residential and light commercial applications. Typical installations include venting for gas furnaces, water heaters, boilers, and other Category I gas appliances that require Type B double wall vent pipe. The tee configuration is used where a branch line must intersect the main vent run, such as when two appliances share a common vent manifold or when a clean-out access tee is required at the base of a vertical vent stack.

Key Features

• 6-inch nominal diameter matches standard B-vent system sizing
• Double wall round construction maintains required air space for Type B vent performance
• Tee configuration supports branch connections in multi-appliance or manifolded vent systems
• Compatible with Type B vent pipe and fittings of the same diameter and system standard

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 6-inch Type B double wall round vent systems used with Category I gas appliances.

Installation Notes

Installation must be performed by a qualified HVAC technician or licensed plumber in accordance with the appliance manufacturer instructions, NFPA 54 (National Fuel Gas Code), and local mechanical codes. Shut off gas supply and allow the appliance to cool before working on any vent component. Ensure all joints are properly secured per the vent system manufacturer assembly instructions and that the completed vent system maintains required clearances to combustibles. Do not mix B-vent components from different manufacturers within the same vent run unless listed for such use.
