Hart Cooley 3ecw Type B Vent Rain Cap 3 Inch

Product Description

The HART COOLEY 3ecw is a round, snap-lock rain cap designed for 3-inch Type B gas vent systems. It installs at the top of a B-vent flue to block rain, debris, and downdrafts from entering the vent while allowing combustion gases to exhaust freely. The snap-lock design speeds up installation without requiring separate fasteners. Weighing 0.46 pounds, it is lightweight enough for single-technician handling on a rooftop. HVAC technicians and gas appliance installers use this cap as a standard termination fitting on residential and light commercial B-vent runs.

Type B vent rain caps are used on atmospherically vented gas appliances including furnaces, boilers, water heaters, and space heaters that terminate through a roof. This cap is sized for 3-inch diameter B-vent pipe. It is a field-installed termination component placed at the final flue outlet above the roofline. The snap-lock attachment method is compatible with standard double-wall Type B vent pipe sections from common vent system manufacturers.

Compatibility

Installation Notes

Installation should be performed by a licensed HVAC technician or gas appliance installer in accordance with the appliance manufacturer instructions and applicable fuel gas codes such as the IFGC. Shut off the gas supply and allow the flue to cool completely before handling any vent components. Snap the cap firmly onto the top of the vent pipe until it seats and locks without gap. Verify the cap termination height above the roofline meets local code clearance requirements before completing the job.
