The ash pit cover is typically located at the bottom of your firebox. Recessed inside the floor, it stores old ashes from your fireplace. It’s usually made of metal to withstand high temperatures. An ash pit cover comes with metal hinges that allow you to open it whenever you need to sweep the ashes away.

Just make sure you use appropriate tools as touching hot embers can be dangerous.

Back and side walls

The back wall holds your fireplace door in place. The side walls are typically made of bricks or stones, especially if you have a masonry fireplace. They help contain the heat and flying embers, protecting you from accidental fires. When it comes to decorating them, you can choose from many textures and colors.

Some modern fireplaces have side vents that further regulate the airflow. They typically come with protecting screens to keep flying embers contained.

Chimney

The chimney is one of the most straightforward components of a fireplace. It directs smoke and fumes out of your home. Burning wood produces toxic fumes that would otherwise harm you. The chimney also contains flying embers, providing you with extra protection from accidental fire.

Chimney Cap

As the name implies, this cap sits atop your chimney. Made of metal, it protects your chimney from elements such as rain and snow. Without it, wood-burning fireplaces couldn’t function properly. A chimney cap further keeps embers contained. Otherwise, they would fall on your roof, potentially starting a chimney fire.

Chimney throat

Corbel is a type of wooden surround that supports your fireplace. It is a 3D profile that rises from the wall. Although it serves mainly a structural function, it’s also an important part of fireplace design.

Crown

Of all the parts of a fireplace, the crown may be the most obscure one. It simply refers to the decorative tile found on top of your chimney. It’s typically thin and wider than the rest of your fireplace. Made of concrete, it also blocks precipitation.

Damper

A damper is a metal place found near the chimney throat. You can control it with a lever. Opening it increases the airflow, allowing your fire to burn brighter. However, it also results in greater heat loss. When you close it, you restrict the airflow your fireplace receives. This is better for conserving heat. Just make sure you don’t overdo it or you may start a chimney fire.

Burning wood with low oxygen can also produce carbon monoxide, a poisonous gas.

Firebox

The firebox is the bread and butter of all masonry fireplaces. It’s usually square or rectangular. It exists to contain the fire, relying on sturdy materials like firebricks. It sits on top of the hearth and under the chimney throat.

Fire doors

Fire doors grant you access to the firebox. They’re typically made of resilient glass, allowing you to watch the flames dancing once you light the fire. You should only open it when you need to restock fuel or light a new fire. Quality fire doors should feature handles made of non-combustible, insulant materials. That way, they won’t burn your hands.

Fire grates

A fireplace grate is a component that holds the wood while it burns. It’s generally made of cast iron, though you can find fire grates made of other metals as well. It features a rib-like bottom that allows for maximum oxygen intake, making the fire burn as bright well as possible.

Flashing

The flashing is a metal sheet found around your chimney. Its purpose is to maximize insulation and make your wood-burning or gas fireplace as waterproof as possible. If damaged, you shouldn’t use your fireplace. When moisture enters the firebox, it can interfere with the combustion. This results in toxic fumes that can be life-threatening.

Fuel

The fuel is what gives your fireplace life. Today, you can choose from many different types of fireplaces. Some burn wood while others burn organic pellets. You can even go for electric ones that don’t need any fuel at all.

Hearth

The hearth is essentially the floor under the firebox. It’s typically made of metal to disperse the heat as well as possible. As a result, the heat dissipates into your room rather than escaping out of your chimney. It also protects the floor under the fireplace from damage.

Mantel

The fireplace mantel is a shelf-like protrusion above the firebox. Though it originally protected the room from flying embers, it’s mostly a decoration today. You can decorate it with vases, pictures, and sculptures to create the living room of your dreams.

Lintel

The lintel is a horizontal beam that supports the chimney. You can find it between the fireplace surround and the chimney throat. Its purpose is purely structural. Some fireplaces use arches instead of lintels, although these are more expensive.

Screen

The screen is a decorative feature placed in front of your fireplace. It’s usually made of glass so that you can see the fire behind it. It also protects the fireplace opening from heat. Screens come in many designs, meaning they are very versatile decorations.

Smoke Chamber

The smoke chamber is the small space above the firebox. The extra spell helps the fire burn brighter, creating much more heat. It is a structural feature that you can’t decorate.

Smoke Shelf

The smoke shelf sits at the bottom of the smoke chamber. Its design blocks smoke, preventing it from re-entering the firebox. This increases the quality of your fire.

Surround

The fireplace surround is used to describe the entire frame around your firebox. It includes the side walls, corbel, and mantel. It has a structural function. However, it’s one of the key elements of fireplace designs as well. Choosing the right fireplace surround determines the overall look of your entire living room.

Roofline and soffit

What is a firebox?

The fireplace’s firebox serves as its physical confines. It is built to endure extreme heat and is often constructed from fireproof materials like brick or metal.

What is a chimney?

Chimneys are vertical structures designed to vent smoke and other combustion byproducts safely outside. It rises above the level of the roof and is typically constructed of brick, stone, or metal.

What is a damper?

Located inside the chimney, the damper is a metal flap that may be opened or closed to control the flow of air and smoke. To regulate the fireplace’s heat output and keep smoke out of the house, this component is crucial.

What is a hearth?

The hearth is the protruding platform in front of a fireplace. It is designed to prevent damage to the floor and walls from flying sparks and is constructed from fireproof materials such as stone or tile.

What is a mantel?
