A brick or stone enclosure forms the basis of the fireplace. Variously known as the fireplace opening or recess or builders opening, it may be set flush with the wall or built out into the room, forming a chimney breast. This chimney breast rises through the height of your home, emerging through the roof to form a chimney stack. At the top of the opening the gather and flue combine to carry the smoke up the chimney. If the chimney is shared by several fireplaces on different floors, it might contain more than one flue.
The masonry over the fireplace opening is supported by a lintel or a brick arch. Old inglenook fireplaces used enormous oak beams, whereas a strong iron strap normally supports an early brick arch. Later on, fireplaces might have a straight arch supported by angle iron, and by the twentieth century cast concrete lintels were the standard.
A hearth, constructed from non-combustible products such as stone or tile-faced concrete, projects out into the room to protect the floor from falling ashes. In most old houses, the hearth was set flush with the floor, although sometimes, a superimposed one was used to raise the level. The space within the fireplace opening, known as the back hearth, is normally level with the hearth itself. A dog grate for burning wood or coal can be placed on this back hearth. However, by the mid-nineteenth century, the mass produced cast-iron register grate which filled the opening, had become the fashion.
To complete the assembly, a mantelpiece, or mantel, or fireplace surround, as it is typically called today, is fitted to frame the grate or fireplace opening. The mantel may be constructed from stone, slate, marble, wood or cast iron. The walls around it might be finished with wood paneling, or even more commonly with plaster, and sometimes, the mantel extends up to form an outstanding chimneypiece. Mirrored overmantels were introduced in the late eighteenth century, and these ended up being the traditional feature of Victorian sitting rooms.

If the chimney is inadequate, or the flow of air is restricted, the fireplace will not work successfully.
