Hart Cooley 8rsc B-vent Round Storm Collar 8 Inch

Product Description

The HART COOLEY 8rsc is a round storm collar designed for 8-inch Type B gas vent systems. Storm collars seal the gap between a vent pipe and the roof flashing, preventing water intrusion at the roof penetration point. This collar is also compatible with 6-inch all-fuel vent systems, giving it added utility across a wider range of residential and light-commercial installations. At 0.39 pounds, it is a lightweight metal component that HVAC technicians and sheet metal installers fit as part of a complete vent termination assembly. Proper installation of a storm collar is a required step in any compliant B-vent roof penetration.

This storm collar is used wherever an 8-inch B-vent or 6-inch all-fuel vent passes through a roof deck. Typical applications include gas furnaces, boilers, and water heaters vented with Type B double-wall vent pipe. The collar slides over the vent pipe and seats against the roof flashing, then is sealed to prevent wind-driven rain and debris from entering the roof-vent gap. It suits residential installations and light-commercial applications with similar vent diameter requirements.

Key Features

• Fits 8-inch Type B gas vent pipe at the roof penetration
• Also compatible with 6-inch all-fuel vent systems
• Lightweight construction at 0.39 pounds for easy single-tech handling
• Round profile matches standard round B-vent pipe geometry
• Designed to seal against roof flashing to block water intrusion

Compatibility

Compatible with 8-inch Type B gas vent systems and 6-inch all-fuel vent systems. Designed as an OEM-style replacement or new-installation storm collar for standard round B-vent roof penetration assemblies.

Installation Notes

Installation is typically performed by a licensed HVAC technician or sheet metal worker as part of a complete B-vent roof termination. Shut down and allow the appliance to cool before working on the vent system. The storm collar should be slid over the vent pipe above the roof flashing and sealed with a listed high-temperature sealant in accordance with NFPA 54 and local mechanical code requirements. Do not overtighten or deform the collar during installation, as a proper round fit is required for an effective seal.
