Hart Cooley 7rt B-vent Double Wall Round Tee 7 Inches

Product Description

The HART COOLEY 7rt is a double-wall round tee fitting designed for use in Type B gas vent systems. This component connects vent sections at a tee junction, allowing branch connections within a venting run. The double-wall construction maintains the air space required by Type B vent standards, which helps keep flue gases moving and reduces heat transfer to surrounding combustibles. At 7 inches in diameter and 2.93 pounds, it is sized for residential and light commercial gas appliance venting applications. Licensed HVAC technicians and sheet metal mechanics are the typical installers of this fitting.

This tee fitting is used in Type B double-wall gas vent systems serving natural gas and propane appliances such as furnaces, boilers, and water heaters. It is suited for vertical and offset venting configurations where a branch connection is required. The 7-inch diameter accommodates higher-capacity appliances or combined venting arrangements commonly found in residential and light commercial mechanical rooms.

Shut off the gas supply and allow the venting system to cool completely before servicing or replacing any vent components. Ensure all vent sections are fully engaged and locked per the manufacturer assembly instructions.
