Hart Cooley 8ral 8 Inch B-vent 90 Degree Elbow

Product Description

The HART COOLEY 8ral is an 8-inch double-wall round 90-degree elbow designed for Type B gas vent systems. This fitting redirects venting at a right angle, allowing installers to route exhaust from gas-fired appliances around structural obstructions or transition between vertical and horizontal runs. The double-wall construction maintains flue gas temperature to support proper draft and reduces heat transfer to surrounding combustible materials. This elbow is a standard component in residential and light-commercial B-vent installations and is handled by licensed HVAC technicians and gas appliance installers.

This elbow is used in Type B double-wall vent systems serving natural gas and propane appliances such as furnaces, boilers, water heaters, and space heaters. It is suited for residential and light-commercial applications where a 90-degree directional change is required within the vent run. The 8-inch diameter sizing accommodates the venting requirements of higher-capacity appliances. Installers select this fitting when the vent path must make a full right-angle turn before connecting to a vertical chase or roof termination.

Key Features

• 90-degree elbow provides a full right-angle directional change in the vent run
• Double-wall round construction maintains draft temperature and limits heat transfer
• 8-inch diameter fits standard Type B vent system components of the same size
• Designed for use with natural gas and propane appliance venting
• Connects within a modular B-vent system for straightforward assembly

Compatibility

Designed as an OEM-style replacement and new-installation fitting for 8-inch Type B double-wall round gas vent systems in residential and light-commercial applications.

Installation Notes

Installation should be performed by a licensed HVAC technician or gas appliance installer in accordance with NFPA 54 and the appliance manufacturer's venting instructions. Shut off the gas supply and allow the appliance and existing vent components to cool completely before servicing or modifying the vent system. Maintain required clearances to combustibles as specified by the fitting manufacturer and local code. Do not mix Type B vent components from different manufacturers within the same vent system unless listed for such use.
