The mantle is a shelf positioned above the hearth. It can also come as a unit built into the fireplace surround. It is most commonly used for display purposes and adorned with knick-knacks and other aesthetic items.

What Does The Mantel Do?

The mantels on modern fireplaces are simply decorative, but it served a vital purpose when it was developed in the middle ages. Like modern range hoods, the mantel directs smoke up the chimney preventing it from invading the home.

The fireplace lintel is horizontal support above the main cavity of the fireplace. Lintels are made of wood, stone, metal, or brick and can be straight or arched.

What Is The Lintel For?

The Lintel provides a vital service by keeping the opening of the fireplace structurally sound. A lintel is integral to a fireplace, and if it becomes damaged, it will need to be repaired by a professional right away. Never use a fireplace with a broken lintel.

Outer Hearth

The outer hearth is the flat, floor-like portion of the fireplace that extends out into the room. It’s made of thick stone or brick, and it can be decorated or used as a spot to store fireplace tools. 

What Does The Outer Hearth Do?

It acts as a buffer between the fire and your floor, catching ashes and embers that may escape the fire. This part of the fireplace was often used to keep food and beverages warm in the past. Today the outer hearth is purely for safety in most homes, although the stone holds heat well to help heat the house after the fire has been extinguished. 

Inner Hearth

The inner hearth is the floor of the fireplace’s firebox, where the fire is built and burned. It is made out of the same material as the outer hearth and extends into the fireplace towards the wall. 

What is The Inner Hearth For?

The inner hearth protects the floor and the rest of your home so you can build a fire safely. It also retains heat very well, prolonging the warmth of a fire. 


The fireplace damper is a flat piece of metal located above the firebox inside the chimney. It acts as a vent and has a knob used to position it. The knob is located on the portion of the fireplace extending into the room, usually centered above the opening or sometimes on the side of the fireplace.

What Does The Damper Do?

The damper controls the flow of air and smoke moving through the chimney using a knob. The damper allows smoke and heat to travel out of the house when opened. When closed, it prevents heat and smoke from leaving the house.

Cleanout Door

The chimney cleanout door is a metal door on the exterior face of the chimney. This door is usually located on the back of the fireplace in the neighboring room or the home’s exterior. Not all fireplaces have a cleanout door.

What is the Cleanout Door For?

The cleanout door makes fireplace waste removal quick and easy. It allows you to remove all the debris from burning with less hassle and mess.

Chimney Cap

The chimney cap sits on top of the chimney on the home’s exterior. The cap is metal and has a flat or peaked top above a wire cage. It is often decorative since it is visible from the home’s exterior.

What Is The Chimney Cap For?

The chimney cap prevents water and drafts from entering your home through the fireplace. The wire around the cap prevents birds and other pesky critters from crawling into the chimney for a warm place to set up shop. They also prevent the risk of fire by trapping any hot ashes that may escape the flue.

What Holds The Logs In A Fireplace?

Andirons and log grates are metal inserts used to hold logs in a fireplace. These items raise the logs off the ground, allowing for better air circulation, reducing the wood’s smoke, and improving burning.

What Is The Difference Between A Damper And A Flue?

A damper is a metal plate inside the chimney that controls airflow through the flue. The damper is located just under the flue. The flue is the passageway that smoke travels up to get out of the home. 

Should You Close The Damper On A Fireplace?

When the fireplace is not in use, the damper should always remain closed to prevent heat or air conditioning loss. The damper should remain open when a fire is burning to prevent smoke from building up inside the home.

What Is The Smoke Chamber?

The smoke chamber is a necessity for the safe operation of a fireplace. It has angled walls like a funnel that forces the smoke up and out of the home. 

Why Is There A Hole In The Bottom Of My Fireplace?

If you’ve found a hole in the floor of your fireplace, you’ve found the ash dump. This hole makes cleanup more manageable by allowing you to scrape ash and debris directly into it. The hole opens into a small chamber that contains the fire waste and usually has a cleanout door for access.

Can The Ash Dump Be Covered?

Yes, you can purchase doors for your ash dump to cover the opening and prevent cold air from coming into the house. You can also use a flat sheet of metal or a large rock to cover it if you need an immediate solution.

Fireplaces are a relaxing addition to any home, and they create an atmosphere of comfort, but how well do they heat? Wood-burning fireplaces tend to release more heat than they create, making them a less ideal option for whole-home heating. They are good at heating small areas, making them useful in emergencies.

Now that you know each part of the fireplace and how they perform, you are ready to tackle any fireplace issues in your path. Make sure to use caution anytime you light a fire in your fireplace, and keep an extinguisher nearby. Good luck and have fun!
