Hart Cooley 7r45 B-vent 45 Degree Elbow 7 Inch

Product Description

The HART COOLEY 7r45 is a double-wall, round B-vent elbow designed to redirect flue gas flow at a 45-degree angle in Type B gas vent systems. This fitting is used to route venting around obstacles or to make directional changes within a venting assembly. At 7 inches in diameter and weighing 1.86 pounds, it is a standard-sized component for residential and light commercial gas appliance installations. Licensed HVAC technicians and plumbers install this elbow as part of a complete B-vent system serving natural gas or propane appliances.

This elbow is suited for use in residential and light commercial Type B gas vent systems, including those serving furnaces, boilers, water heaters, and other Category I gas appliances. The double-wall construction maintains proper flue gas temperature to support draft and reduce condensation within the vent assembly. It is installed where a 45-degree directional change is required along a vertical or offset vent run.

Key Features

• 45-degree elbow angle for directional changes in B-vent runs
• Double-wall round construction maintains flue gas temperature and supports proper draft
• 7-inch diameter fits standard Type B vent system components of the same size
• Lightweight at 1.86 pounds for easier handling during installation

Compatibility

Designed as an OEM-style replacement or new-installation component for 7-inch Type B double-wall round gas vent systems.

Installation Notes

Installation should be performed by a licensed HVAC technician or plumber in accordance with the appliance manufacturer instructions and applicable codes including the International Fuel Gas Code (IFGC). Shut off and lock out the gas supply and allow the vent system to cool completely before servicing or replacing any vent components. All vent sections and fittings must be properly secured and supported per code requirements.
