Honeywell rc-6 Barometric Draft Damper 6 Inch

Product Description

The HONEYWELL rc-6 is a standard barometric draft damper control with collar, designed to regulate flue draft in residential and light-commercial heating systems. Barometric draft controls maintain consistent negative pressure in the flue by allowing dilution air to enter the vent connector when draft exceeds the set point. This prevents over-firing and stack loss caused by excessive draft. The rc-6 is sized at 6 inches to match common single-wall flue pipe diameters. It ships with a collar for direct connection to the vent connector. Licensed HVAC technicians and heating oil service pros are the typical installers.

The rc-6 is rated for use on oil-fired, wood-burning, and coal-burning heating appliances connected to natural-draft flue systems. It is commonly installed on residential oil boilers and furnaces, as well as solid-fuel heating units where flue draft regulation is required. The 6-inch size fits standard single-wall vent connector pipe used on many residential heating appliances. This control helps stabilize combustion efficiency by preventing excessive draft from pulling excess heat up the flue.

Installation Notes

Installation is performed by a licensed HVAC technician or qualified heating service professional. Shut down the heating appliance and allow the flue to cool completely before beginning work. The damper is typically installed in the horizontal vent connector between the appliance and the chimney, per appliance manufacturer instructions and applicable codes such as NFPA 31 for oil-burning equipment. Do not install on power-vented or sealed-combustion appliances.
