In order for your fireplace to run at peak efficiency and last for a long period of time, paying attention to fireplace construction is incredibly important. A carefully designed fireplace will provide regular amounts of heat and sturdy design so that you and your family can enjoy a steady source of warmth and comfort. There are many designs and types of fireplaces available and a wide variety of materials are used during the construction process. Basic fireplace construction involves a standard but detailed process.

The dimensions of each part of the fireplace must be narrowed down to their critical elements to come together for the final piece. The main components of every fireplace include a supportive foundation, an ash pit, a firebox, bonding with fireclay mortar, a smoke shelf, throat, smoke chamber, shaft, and chimney.

The foundation is the most important part of the fireplace construction process, as this provides the support your fireplace needs for the remainder of the model. It is often called a footing, and provides the basic dimension and reinforcement of the selected design. Laying up the foundation wills with usable ash will help create an ash pit. The ash pit is the area where any ashes from the fire are swept into an area to be removed at a later time. The ash pit must be constructed so that ashes can be deposited and removed easily, but also resistant to moisture penetration. Construction of this part of the fireplace continues to create the inner and outer hearth, and different techniques are used to accomplish this by bricklayers and architects.

The fireplace butt alls support and enclose the firebox, and these will extend from the foundation of the fireplace to the area where the chimney starts. The firebox is bonded with fireclay mortar or masonry units to fit inside the walls of the fireplace, and is secured with tight joints. The smoke shelf projects out from the rear butt, and the throat, smoke chamber, and liner support are often constructed using masonry units, and a damper and lintel will be put into place according to the manufacturer’s instructions.

The chimney is often constructed of a liner, fire stops, and a water tight cap. These help make sure that your fireplace is as efficient and functional as possible. The chimney must be at a specified height above the roof, and will need to include a spark arrester for optimal fire safety and protection. Finally, a smoke test can prevent any unsafe ash accumulation and other incidences.
