Install balancing damper

For the side with the handle, cut a piece of sheet metal to cover the slit, drill a hole for the other pin and secure the cover with sheet metal screws. Attach the handle with the included wing nut. The airflow is not linear, so closing the damper halfway will not cut the airflow in half.

It will be a process of trial and air, sorry error, until you get the desired effect. The damper should always be open at least a third of the way. You may have to readjust the position in the winter and summer, so it is a good idea to make a mark on the collar to so the correct position. Brand Directory.

This is not a good practice for several reasons; 1 the dampers on floor and wall registers can completely seal off any airflow which can lead to the branch duct being pressurized and splitting that will lead to energy being wasted, 2 the dampers on floor and wall registers can be very noisy which can be annoying since they are in the room they serve, 3 the dampers can be easily moved by children or when cleaning and change the airflow rate.

If you have the option of putting it closer to the furnace then do that. It will be just as effective and you will have no noise. Asked on by Brian 2 Q: On a 6 damper in the full closed position, how much airflow is allowed to pass?? A: Depends on the pressure. These are not meant to be full closure. There is a gap all around the balancing door so with high pressure a fair bit of air would go by.

Asked on by Andy 3 Q: How do I determine from the wing nut position on the outside of the ductwork whether the damper is closed or open?

A: At one end of the slot that the wingnut slides in is a pointer that indicates the position of the damper. Do I simply cut the duct and install it in-line, using a clamp or tape?

A: Yes, that is exactly how it is done. The damper will essentially act as a coupler. Asked on by Fred. At its most basic, airflow balancing involves opening and closing supply register dampers to more evenly condition a home. Technicians open or close dampers based on how much airflow each register receives and what is needed to condition a room based on its load calculation. The damper should be located near the takeoff of the main duct trunk.

Do all HVAC systems have dampers? HVAC systems utilize dampers in the ductwork to control the way air flows in your home. You should be able to access and adjust them manually. Make sure all of the dampers in your home are completely open. Sometimes dampers can get stuck closed or can become loose and close on their own.
