Hart Cooley 4ESC SA11265 B-vent Storm Collar 4 in

Product Description

The HART COOLEY 4ESC SA#11265 is a 4-inch B-vent storm collar designed to seal the clearance between a B-vent pipe and a roof penetration. It prevents water intrusion at the roof line by forming a tight barrier around the flue pipe where it exits the structure. This component is a standard part of any gas appliance venting system that passes through a sloped or flat roof. Installation is performed by licensed HVAC technicians or plumbers working on gas appliance venting systems.

This storm collar is sized for 4-inch B-vent pipe and is used in residential and light commercial gas appliance installations. Typical applications include venting for gas furnaces, boilers, and water heaters that use Type B double-wall vent pipe routed through the roof. It is installed at the roof flashing point to complete a weathertight seal and is a required component in code-compliant venting assemblies.

Key Features

Installation Notes

Installation is typically performed by a licensed HVAC technician or plumber. Shut off the gas appliance and allow the vent pipe to cool before handling any venting components. The storm collar should be slid over the B-vent pipe and seated firmly against the roof flashing, then sealed with appropriate roofing sealant per local building codes and IFGC requirements. Do not operate the appliance until the venting system is fully reassembled and verified to be leak-free.
