The 10 Basic Parts of a Chimney are More Than Bricks

fireplaceMany people confuse a fireplace with a chimney. The fireplace is only one part of the puzzle. Many additional components of a chimney are critical to the safety and efficiency of your fireplace and chimney units. The parts of a chimney that you should be aware of are listed below.

The Building Blocks

Your chimney’s foundation is made up of bricks. Your safety, as well as the structural integrity of your chimney, is jeopardized if they’re in bad shape. At the very least, your fireplace will not function properly.

If your bricks are broken, you face the chance of moisture getting into your home, which may cause damage as well as mold and mildew.

Flue in the Chimney

The chimney flue is not the same as the chimney liner, despite popular belief. The flue is a vertical tube that permits combustion products to leave your home. The flue must be lined by law for homeowners.

Liner for Chimneys

A chimney liner keeps fire contained in the chimney and keeps it from spreading throughout your home. Clay tiles are the most popular liners since they are both long-lasting and cost-effective.

If you’re building a new fireplace, you may need to add a new liner because liners aren’t one-size-fits-all. If the liner does not fit the device, you risk increasing the danger of indoor pollution.

Liners must be replaced as soon as a crack appears, no matter how little. You should not use your fireplace until the liner is changed.

Cap for the Chimney

A chimney cap keeps the elements outside from entering into your property, such as:

  • Rain\sSnow\sSleet\sDowndrafts
  • strewn about (leaves, branches)
  • Animals are creatures that live in the wild (such as birds and bees)

Because the wire mesh functions as a spark barrier, chimney caps help prevent roof fires.

Covers for Chimney Chases

A chase cover is a chimney cover that is situated on top of prefabricated, factory-built chimneys and is used to cover the chimney entrance. Chase covers are available in a number of materials, including:

  • Copper\sAluminum
  • Stainless steel is a durable material.
  • Steel that has been galvanized

A lot of people opt for stainless steel & copper because they are durable, don’t rust & last a long time. Aluminum covers are popular because they offer a wide range of colors. Galvanized steel may offer a temporary solution by preventing rust, but it will have to be replaced after some time.

Flashing Chimneys

Chimney flashing is used to prevent moisture and leaks, including damage to your chimney, roof, and rooms below. There are many different materials that can be used but generally it will be made from one of four materials: vinyl/aluminum/copper and steel.

Crown of the Chimney

A chimney crown, also called a chimney wash, is a cement slab that covers the top of your chimney. This protects the flue opening and prevents any water from making it into your fireplace.

Throat Damper or Fireplace Damper

Dampers are also known as throat dampers because they are installed in the chimney’s throat above the firebox.

When your fireplace is in use, it’s important to close the damper on the chimney. Otherwise, warm air will escape via the chimney when it’s not in use. When using your fireplace, make sure that the damper is open before you start a fire

Damper maintenance is important to keep your fireplace and chimney safe. If the damper is broken, smoke may not be able to leave your house if it is stopped up and a draft may happen.

Chamber of Smoke

Between the flue and the damper lies the smoke chamber. The smoke chamber compresses combustion byproducts, allowing them to leave through the chimney instead of reentering your home.

Components of a Fireplace

  • The following are the components of a fireplace:
  • The firebox is the place where the fire really burns.
  • The hearth is the floor of the fireplace.

In medieval times, the mantel served as a smoke collector and is now employed as a decorative frame surrounding the fireplace.

Glass doors: In addition to providing a nice view of the fire, they also act as a protective barrier.

The term “fireplace insert” refers to a fire-resistant box that fits into an existing fireplace.

  • A door in the center of the firebox permits ash to be easily removed.
  • An ash pit is a storage area at the base of a fireplace that collects ash.
  • A cleanout door is a door in the chimney that is located behind the fireplace or on the exterior of the home and allows rubbish to be removed.
