The HONEYWELL gvd-7pl is a 7-inch vent damper equipped with a black motor assembly, designed to control flue gas flow in residential and light commercial heating systems. Vent dampers reduce standby heat loss by closing the flue when the burner is off, improving overall system efficiency. This unit is sized for 7-inch vent pipe and includes the motor drive mechanism needed for automatic operation. Licensed HVAC technicians and gas appliance service professionals typically install this component as part of a gas furnace or boiler venting system.
The gvd-7pl is suited for installation on B-vent or single-wall vent connector piping serving gas-fired furnaces, boilers, or water heaters that require automatic vent damper control. The black motor designation identifies the motor assembly color and wiring configuration associated with this product family. This damper is intended for systems where the flue diameter matches the 7-inch nominal pipe size. It is a field-installed accessory that integrates with the appliance control circuit to open and close automatically with each call for heat.
Designed as an OEM-style replacement or field-installed vent damper for gas-fired furnaces, boilers, and water heaters using 7-inch nominal vent connectors. The associated motor assembly part number referenced in the product data is RVGP-KS-7BKF.
Installation of this vent damper should be performed by a licensed HVAC technician or qualified gas appliance service professional. Shut off gas supply and disconnect electrical power to the appliance before beginning any work on the venting system. The damper must be wired into the appliance control circuit so it proves open before allowing burner ignition, per manufacturer wiring guidelines and applicable local codes. Follow all local mechanical and fuel gas codes, including IFGC requirements, for vent connector installation and appliance venting.
