Parts of a Fireplace Explained with Diagram

Fireplaces bring not only comfort to the home, but also elegance. This is a feature that most homeowners want. Traditional stone fireplaces with wood burning stoves have a special appeal. However, the quality of indoor air is becoming increasingly precarious as a result of wood burning. Therefore gas fires were preferred. They are high-energy, maintenance-free and can be used almost anywhere.

A fireplace is different from a chimney and has its own structure, but both require qualified cleaning at least once a year. Do you know the different parts of the fireplace? You may not even know how your fireplace works, and reading this will help you use it better.

A chimney is complex and encompasses more than just a fireplace where you can see the movement of smoke through the sight. Learn more about the components of your fireplace. You may not need this information to pass the exam, but it may come in handy in the future, especially when you talk to chimney sweeps about your problems or questions.


The base of the chimney is usually made of solid bricks or boulders. This sturdy device is designed to withstand the heat of hot ashes and structurally protect the chimney.


The fireplace is the space under the mantel that normally protrudes into the room. A non-combustible fireplace is essential for a wood-burning fireplace because it prevents the floor from sparking and causing a fire that could damage the home. For a more authentic feel, many people add a gas fireplace, but it’s not necessary. Chimneys may be raised or aligned with the surrounding ground. Slabs or slabs of stone are sometimes used to build chimneys. They often become larger, deeper and higher than necessary for use as side tables.

Topper or internal fire

The combustion chamber is also called the inner chamber. This is the part of the fireplace where the fuel is burned and the smoke is visible. It is also the only clearly visible access to the interior of the chimney. The heat source, the oxygen or air and the fuel (usually wood) are the three elements that make up the combustion triangle and are essential to getting a fire in the stove.

External stove

The outdoor fireplace is made of heat-resistant steel and rests directly on the ground when the fireplace is open. An outdoor fireplace can protect the home from an explosion.

Chimney district

The fireplace surround simply means the immediate area around the indoor fireplace. In most cases, non-combustible items should be kept near the firebox. Outside of this non-combustible environment, however, homeowners have more options for environmental design. Some choose wooden panels or legs connected to the top shell. Others opt for a decorative tile in the room. The surround is the part of the fireplace that gives it personality, and every style is different.


In America, the mantel has always been the focal point of the fireplace, but newer styles have a more streamlined look and often do away with the mantel. The hood played an important role in capturing the smoke. The use of the fireplace has long been dead except for aesthetic purposes.

Chimney side

The front of the fireplace is under the chimney and the top of the fireplace. This component must be durable and able to withstand the high temperatures generated by the fireplace. This surface is usually made of stone.


The function of the lintel is to support the weight caused by the inside opening of the fireplace. This feature also occurs in the openings of windows, doors and arches.


The throat is the opening above the chimney where the ventilation mechanism of the chimney is actuated. The valve is usually installed when the chimney is built. More recently, the requirements for the throat have been increased so that it must be at least 8 inches higher than the inner hearth, whereas previously it was 6 inches. If the boiler begins to emit smoke into the house, it is a sign that the boiler throat is not built properly or that it needs repair or maintenance.

Shock absorber

A movable metal door that seals the chimney from the outside and fits into the chimney flue opening on the inside of the chimney is called a chimney damper. When using a chimney, the damper should always be open to allow smoke and fumes to escape from your home. In most cases, the valve should always be closed to prevent debris from entering the building.


The flint, usually made of fireclay, is located at the back of the fireplace. These special stones are designed to withstand the temperature of the fireplace without being affected by it.

Ashtray and ash removal valve

The ash drawer is located in the centre of the stove, making it easy to remove the ash from the stove. The ash door is opened to bring the ashes into the ash pit. The ash pan is a space directly below the ash pan where the ash falls into after the door is opened.


The ash pit, located below the ash removal area, collects the spilled ash. The ashtray can be emptied regularly. This reduces the risk of accumulation of flammable by-products.


The floor is a flat surface under the ash tray. Generally, this element of the fireplace is located in the foundation.

Cleaning the exit door

The chimney door, which is usually located in the basement, makes it easy to clean the ash drawer.


Each of these key fireplace components can be customized to fit your style and budget. Since the fireplace is often the focal point of a room, careful planning is required to make the most of this architectural element.
