Most homeowners do not even realize how complex a chimney really is. Understanding the anatomy of a chimney can help you identify potential problems much easier.

First, there is the damper, this is what seals off the flue of the chimney when it is not being used. This helps to keep air from flowing into the chimney. If you notice a draft from your fireplace, you might want to check the damper to make sure that it is sealed properly.

The smoke chamber starts above the damper and continues to where the flue tiles start. Keeping this clean is important as this is where most chimney fires start.

The smoke shelf is in the area where the chamber and firebox intersect. The purpose is to collect debris and rainwater that falls into the flue. It also will help prevent down drafts so that your home does not fill up with smoke.

The chimney liner is the lining of the chimney that allows all of the particles, smoke, and gasses to leave the home safely.

The chimney crown is the roof of the chimney. It will cap the end of the chimney, leaving only the flue open. This protects the chimney from deterioration and damage from the weather.
