Parts of a Fireplace & Chimney: 10 Things You Need To Know

I love hanging out with my wife in front of the fireplace. It’s a ritual we do every year on Christmas Eve and it can be done a few hours before or after the holiday.

A few minutes of reading by the fire, some small talk and then a few glasses of wine, some great conversation and a few hours of “hanging out” is a lot of fun, and very romantic. I love it.

If they are damaged moisture may get into the home which can lead to the growth of mold and mildew.

#2. Chimney FlueChimney Flue

This is different than the chimney liner. The flue is the vertical shoot that will allow smoke and other material to leave the home. Homeowners with a fireplace are required by law to line the flue.

#3. Liner


If there is a fire, the chimney liner will prevent it from spreading to the home. Clay tiles are common liners since they are durable. You may need to add a new liner if you are installing a fireplace. The liner needs to fit properly to keep pollutants from getting into the home.

If there are cracks the liner will need to be replaced. Even a small crack can lead to a big issue.

The chimney cap will prevent elements from getting inside the home. This can include:

  • Rain

#5. Chase Cover

A chase cover is often on prefabricated chimneys. They can be made from:

  • Aluminum

This is sometimes called the chimney wash. It is a slab of cement that will cover the top of the chimney. This will cover the entire top and prevent water from getting in.

#8. Damper or Throat Damper

This is located above the firebox in the throat of the chimney. It will seal the fireplace when it is not being used. This way the hot air does not escape from the home. be sure this is open when the fire is on so the smoke can escape.

The damper must be in good condition. If it is broken smoke will get stuck in the home. it can also make the home drafty.

#9. Smoke chamber

The smoke chamber is between the flue and the damper. It compresses byproducts so they are able to exit by the chimney and stay out of the home.
