The fireplace in your home can be a source of warmth and pleasure, but it’s important to understand the role of maintenance which can keep you and your home safe. Playing with fire is never a good thing, and that’s what you’re doing if you don’t hire a professional chimney sweep to inspect your fireplace and chimney annually and become thoroughly familiar with steps to ensure the proper function of your fireplace.
There’s a lot more to your fireplace than what a casual observer might see. Become acquainted with your fireplace’s anatomy so that you can get the most out of it and stay safe at the same time. You’ll be better equipped to communicate your concerns to a professional if a problem arises, by knowing the parts of your fireplace too.
The fireplace mantelpiece or mantel was originally used in medieval days as a hood which caught smoke, and it projected over a grate. As the design of fireplaces has changed, the role of the mantel has lessened in importance. The era in which the mantelpiece was the focal point of the fireplace and the perfect place for favorite photographs and trophies has passed so that the mantel has arguably never had less significance.
The area between the firebox and the mantel is the fireplace’s face. This part of the structure is typically constructed of brick, and it must be sturdy and capable enough to withstand the heat from the fireplace below it.
The lintel is similar to a feature used in archways, door openings, and window openings. The lintel’s function is to help bear the load created by the inner hearth or firebox.
Also called the inner hearth, the firebox is the main area that you see in a fireplace where the combustion takes place and the fire burns. The design of the firebox is vital to the successful operation of the fireplace. Common defects in fireboxes involve dimensions, heat damage, and water damage.
The chimney damper is the metal door that is used to close off the chimney from the fireplace. The door is operated by a long metal chain the hangs down and allows the damper to be opened and closed. The damper should be open when the fireplace is in use and closed at all other times to limit a draft in the home.
The throat of the fireplace is just above the inner hearth. This is where the firebox ends and the venting system of the fireplace begins. Traditionally, a throat damper is placed there during construction. There is now a requirement stating that the throat must be at least 8 inches above the fireplace opening. Previously the requirement was 6 inches. If you have a fireplace that tends to leak from the firebox, it’s typically because the throat isn’t constructed properly.
The firebrick is brick usually made of fire clay that lines the back of the firebox. These bricks are especially made to bear up under the heat of a firebox without being damaged.
The area which occupies the floor just outside of the inner hearth is the outer hearth. This component of your fireplace is constructed of heat-resistant material to minimize the chance that the fire will spread out of control.
Ash Dump Door
Located in the middle of your firebox, the ash dump door makes it easy for you to remove ash from the firebox. Open the dump door to move the ash into the ash dump.
The space directly below the ash dump door is the ash dump, where the ash falls when the ash dump door is opened.
The ash pit is located beneath the ash dump and is the place where dumped ash is collected. The pit should be emptied frequently, which will help to prevent dangerous flammable byproducts from accumulating.
Clean Out Door
There is a clean out door in your fireplace which you use to clean the ash dump. This part of your fireplace is often located in the basement.
The horizontal surface underneath the ash pit is the footing, and it’s often located in the basement or outside to make it easier to remove ash.
The foundation of your fireplace is a sturdy structure usually made of cinder block or heavy duty brick. The foundation provides structural support for the chimney. It can potentially be exposed to hot ash; so it should be constructed to be able to withstand the heat.
