Hart Cooley 3eal 3 in Type B Vent 90 Degree Round Elbow

Product Description

The HART COOLEY 3eal is a 3-inch double-wall Type B gas vent 90-degree round elbow used to route venting systems through direction changes in residential and light commercial gas appliance installations. This fitting connects standard Type B vent sections and allows a 90-degree turn in the vent run. The double-wall construction maintains flue gas temperature and reduces heat loss to surrounding structure. It weighs 0.78 pounds and fits 3-inch Type B vent pipe. Licensed HVAC technicians and gas appliance installers handle this fitting as part of a complete venting assembly.

This elbow is suited for use in natural gas and propane appliance venting systems, including furnaces, boilers, and water heaters that require Type B vent. The 90-degree angle supports installations where the vent run must make a right-angle turn to reach the exterior termination point. The round profile and standard flat configuration make it compatible with typical residential venting layouts. It is used in both new construction and retrofit venting projects.

Installation Notes

Type B vent fittings are installed by licensed HVAC technicians or gas appliance installers in accordance with the International Fuel Gas Code (IFGC) and the appliance manufacturer's venting instructions. Power down and shut off the gas supply to the appliance before servicing or modifying any vent section. All vent joints must be secured per the vent manufacturer's assembly instructions, and vent runs should be inspected for proper slope, clearance to combustibles, and support spacing.
