Hart Cooley 4ECW SA11265 B-vent High Wind Cap 4 in

Product Description

The HART COOLEY 4ECW SA#11265 is a 4-inch B-vent high wind cap designed to terminate Type B gas vent systems at the roofline or sidewall. It prevents backdrafting and wind-driven rain intrusion while allowing combustion gases to exhaust freely from natural-draft gas appliances. Licensed HVAC technicians and gas service professionals install this cap as part of compliant vent terminations on furnaces, water heaters, and boilers using Type B double-wall venting.

This cap is suited for residential and light commercial applications where 4-inch Type B vent pipe terminates above the roofline. High-wind designs use directional or baffled construction to maintain positive exhaust flow even in gusty or variable-wind conditions, reducing the risk of downdraft and nuisance shutdowns on standing-pilot or intermittent-ignition appliances.

Key Features

• Designed for 4-inch Type B double-wall gas vent systems
• High-wind profile helps resist backdrafting in exposed or elevated termination points
• Protects vent opening from rain, debris, and bird entry
• OEM-style replacement fitting for standard B-vent termination assemblies

Compatibility

Designed as an OEM-style replacement termination cap for 4-inch Type B gas vent systems used on natural-draft gas furnaces, water heaters, and boilers.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified gas service professional in accordance with NFPA 54 and local mechanical codes. Shut off the gas supply and allow the appliance to cool completely before servicing any vent component. Ensure the cap is secured to the vent pipe per manufacturer instructions and that clearances to combustibles and roof surfaces meet applicable code requirements. Do not operate the appliance until the termination cap is fully seated and all vent joints are properly connected.
