Hart Cooley 10r18 Type B Round Vent Pipe 10x18 Inch

Product Description

The HART COOLEY 10r18 is a double-wall Type B round vent pipe section designed for Category 1 gas appliance venting applications. It measures 10 inches in diameter and 18 inches in length, with an aluminum inner wall and a galvanized steel outer wall. The two-wall construction maintains flue gas temperature to support proper draft while keeping the outer surface cooler for safer clearance-to-combustibles installations. Licensed HVAC technicians and gas fitters install this pipe as part of a listed B-vent system serving natural gas or propane appliances that operate with non-positive vent pressure and flue gas temperatures below the 480-degree-F threshold for Category 1 equipment.

This pipe section is used in residential and light commercial venting systems connected to Category 1 gas appliances such as furnaces, boilers, and water heaters. It is sized at 10 inches in diameter, making it suited for larger residential equipment or commercial appliance venting where higher flow capacity is required. The 18-inch length allows for flexible routing within a B-vent system. All components must be part of a listed B-vent assembly and installed in accordance with the appliance manufacturer instructions and the International Fuel Gas Code.

Key Features

• Double-wall construction with aluminum inner wall for corrosion resistance against flue condensate
• Galvanized steel outer wall for structural durability and exterior protection
• 10-inch diameter accommodates higher-capacity Category 1 appliance venting
• 18-inch length provides routing flexibility within a B-vent run
• Round pipe profile for standard B-vent system compatibility
• Rated for Category 1 non-positive-pressure venting of natural gas and propane appliances

Compatibility

Designed as an OEM-style component for use in listed Type B double-wall round vent systems serving Category 1 gas appliances. All fittings, connectors, and sections must be from the same listed B-vent system and diameter series to maintain listing compliance.

Installation Notes

Installation must be performed by a licensed HVAC technician or gas fitter in accordance with the International Fuel Gas Code and the appliance manufacturer venting instructions. Shut off gas supply and allow the appliance to cool completely before servicing or extending an existing vent system. Maintain required clearances to combustibles as specified by the B-vent system listing. Do not mix vent pipe diameters or components from different listed vent systems within the same assembly.
