Turn the knobs clockwise to reduce the airflow, or turn it counterclockwise to increase airflow.
Does closing damper make fire hotter?
As the fire burns down the amount of air needed drops down, so "banking the fire" by partially closing the damper on the bed of coals reduces the amount of heat drawn out of the house overnight.

Can you control the barometric pressure in your house?
Allow for more ventilation options Controlling the air flow from outside to inside is the key to managing negative air pressure indoors. If you don't have proper ventilation, you can try regulating levels by opening windows, using exhaust fans, and avoiding cooking with fuel-induced appliances indoors.
Does a wood furnace need a barometric damper?

One of the most misunderstood components inside a boiler room is the barometric damper, which is used to control the draft inside a boiler. It is installed on boilers that use a Category I vent. To understand how the barometric damper operates, we need to understand what draft is. We all know that when air is heated, it will rise.
Buffer solution

Are Barometric Dampers Essential on Wood Stoves?
All wood-burning stoves do need a system that enables air to reach the fire. The airflow can be regulated by a barometric damper, a flue damper or simple vents that allow air to access the fire. Selecting a damper system is completely up to the preference of the user, depending on what they're most comfortable with.
How to Regulate the Draft on a Wood Stove
The draft in a stove can be tricky to deal with because if you give to much air, or not enough, it can affect the heat coming away from the fire. The damper needs to bring in "fresh" air, also known as a draft, into the stove in order to push the emissions from the fire up and out of the chimney.
How a Barometric Damper Functions
A barometric damper can be summarized as an automatic damper regulator for stoves. As previously mentioned, it's not the ideal system to use on a wood stove.
