Hart Cooley 6ecw B-vent Rain Cap Round Snap Lock 6 Inch

Product Description

The HART COOLEY 6ecw is a round snap lock rain cap designed for 6-inch Type B gas vent systems. It mounts 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 secures the cap without tools, making field installation straightforward. This cap is used by HVAC technicians and gas appliance installers on residential and light commercial venting systems. Weighing 1.02 pounds, it is sized for 6-inch B-vent pipe and fits the standard round termination profile.

This rain cap is suited for Type B double-wall gas vent terminations on natural gas and propane appliances such as furnaces, boilers, and water heaters. It is installed at roof level or through-wall termination points where the vent exits the structure. The snap lock connection method allows the cap to seat firmly on the vent pipe without mechanical fasteners, reducing installation time during new construction or service calls.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified gas appliance installers. Shut off the appliance and allow the flue to cool before handling the vent cap at the termination point. The snap lock connection should be seated fully and verified to be secure before returning the appliance to service.
