Hart Cooley 12rc B-vent Rain Cap Round Snap Lock 12 Inches

Product Description

The HART COOLEY 12rc is a round, snap-lock rain cap designed for 12-inch B-vent flue systems. It mounts at the top of a Type B gas vent to block precipitation, debris, and downdrafts from entering the flue while still allowing combustion gases to exhaust freely. The snap-lock design allows for fast, tool-minimal installation without the need for sheet metal screws or special fasteners. At 4.83 pounds, this cap is sized for large-diameter residential and light-commercial venting applications. HVAC technicians and plumbers working on gas appliance installations or replacements are the typical installers.

This rain cap is suited for 12-inch Type B double-wall gas vent systems serving natural gas or propane appliances such as furnaces, boilers, and water heaters. The round profile matches standard round B-vent pipe terminations. It is appropriate for both new construction venting runs and service replacement on existing systems where the original cap has corroded, cracked, or gone missing.

• Round profile sized for 12-inch B-vent flue pipe

Installation Notes

Installation should be performed by a licensed HVAC technician or plumber familiar with Type B venting requirements under NFPA 54 and the International Fuel Gas Code. Shut off the gas appliance and allow the flue to cool completely before working at the vent termination. Confirm the cap diameter matches the installed B-vent pipe size before seating. Follow the vent manufacturer instructions and local code requirements for minimum clearances at the termination point.
