Hart Cooley 5ef B Vent Roof Flange 5 Inches

Product Description

The HART COOLEY 5ef is a standard B-vent roof flange designed to seal and support a 5-inch Type B gas vent pipe at the roof penetration point. It provides a weather-tight termination base where the vent exits the roof deck, preventing water intrusion while maintaining the required clearances for double-wall B-vent systems. Rated for roofs with a pitch up to 5/12, this flange is a standard component in residential and light-commercial gas appliance venting systems. HVAC technicians and plumbers install it as part of a complete B-vent assembly serving gas furnaces, water heaters, or boilers. The unit weighs 1.80 pounds.

This roof flange is used where a 5-inch B-vent riser passes through a sloped roof surface with a pitch no greater than 5/12. Typical applications include natural-draft gas furnace venting, atmospheric water heater venting, and boiler vent stacks in residential construction. It is installed at the roofline as part of a Listed Type B vent system and works in conjunction with B-vent pipe sections, elbows, and a storm collar to complete the through-roof assembly.

Installation Notes

Installation is typically performed by a licensed HVAC technician or plumber in accordance with the appliance manufacturer instructions and the International Fuel Gas Code (IFGC). Shut off the gas appliance and allow the vent system to cool completely before beginning any work at the roof penetration. A storm collar and appropriate roofing sealant should be used in conjunction with this flange to ensure a weather-tight seal. Always verify that the complete B-vent assembly carries a Listed rating and that clearances to combustibles meet code requirements.
