When it comes to your chimney, the warm air, including smoke, rises up from the heat source (e.g.. your wood stove or furnace) and through the chimney flue. A good, strong draft pulls the smoke and byproduct gasses out of the home, replacing it with cooler air, which continues to push the smoke and gasses out… It’s a great cycle.
Draft and Flow
Although most people don’t realize it, the air moving up your chimney works under the same set of physical principles as water flowing in a hose or pipe. Furnaces, water-heaters, fireplaces and woodstoves are examples of fuel-burning appliances that need large volumes of air for combustion. Unless they are specifically equipped to draw air in from outside the house, such as direct vent appliances, operating them can reduce the inside air pressure. There are a variety of mechanical devices on the market that help provide the necessary replacement air to balance the air pressure needs of your house system. A throat damper closes the base of your chimney and insulates your home from cold air. It’s easy to check if a throat damper is open or closed since it’s built into the fireplace and can be seen at the top of the firebox.
Built with brick or stone, traditional masonry chimneys include a firebox, in addition to a flue. A chimney like this will also feature a crown at the top to prevent water damage. Prefabricated chimneys have a firebox and cap, but they vent through a pipe, not a flue within the chimney.
Of course, that means the smoke has nowhere to go except for back into the room. By the time you have noticed larger cracks, leaks inside your home, or efflorescence on the exterior of your chimney, your home may already have sustained some expensive damage.

How to Know if the Damper is Open
Additionally, the chimney’s age plays a significant role in its deterioration. As the chimney ages, the mortar joints can weaken, allowing water to seep in and accelerate the degradation process. Moreover, poor construction or design flaws can contribute to structural problems manifesting as chimney masonry damage. If you find yourself wondering whether or not your chimney is working at all, an air pressure issue could be to blame.
