Hart Cooley 8r45 B-vent 45 Degree Elbow 8 Inch Round

Product Description

The HART COOLEY 8r45 is a double-wall, round B-vent elbow designed for natural gas and propane appliance venting systems. The 45-degree bend allows installers to route flue gases around obstructions or transition vent runs at a shallower angle than a standard 90-degree elbow. The double-wall construction maintains draft performance and meets the clearance requirements associated with Type B vent. Licensed HVAC technicians and plumbers install this fitting as part of a complete B-vent system serving furnaces, water heaters, boilers, and other Category I appliances.

This elbow fits an 8-inch B-vent system and is suited for residential and light commercial applications where a 45-degree directional change is needed in the vertical or horizontal vent run. The round profile and standard flat configuration allow it to integrate with other standard 8-inch B-vent components. It is commonly used in new construction and replacement venting projects where local mechanical codes require listed Type B gas vent fittings.

Key Features

• 45-degree elbow angle for gradual directional changes in vent runs
• Double-wall round construction maintains proper flue gas temperature and draft
• 8-inch nominal size matches standard B-vent system components
• Standard flat profile for straightforward integration into existing vent assemblies
• Lightweight at 2.08 pounds for easier overhead and attic installation

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 8-inch Type B double-wall round gas vent systems used with Category I natural gas and propane appliances.

Installation Notes

Type B vent installation should be performed by a licensed HVAC technician or plumber in accordance with NFPA 54, the International Fuel Gas Code, and local mechanical codes. Shut off the gas supply and allow the appliance to cool completely before servicing or modifying any vent connection. Maintain all required clearances to combustibles as specified by the vent system manufacturer and applicable codes. Do not mix B-vent components from different manufacturers within the same vent system unless the components are listed for combined use.
