Fireplace Design - Ensure Yours Is Practical And Beautiful
Alive with merrily crackling logs, brightly blazing coals, or softly simmering embers, it can match any human mood.
An open fire kindles and sustains an air of sparkling gaiety or of calm serenity, with equal ease.
It can be the leavening for laughter and conversation in social gatherings.
It also can be the touchstone for quiet reminiscence in relaxing solitude.
Because of these subtle, satisfying influences, the fireplace continues to hold and expand its centuries-old popularity as the heart of the home.
Proper Basic Design Is The Key To Fireplace Efficiency Successful fireplaces must be planned right, with each element correctly proportioned in relation to the others.
When you stick to proven structural principles, your fireplace will give more pleasure and more heat.
The different elements of a fireplace are: (1) the hearth with built-in ash dump, (2) the firebox of proper shape for reflecting maximum heat, (3) the throat fitted with a damper as wide as the fireplace opening, (4) the smoke chamber with smoke shelf in back of the damper, and (5) the flue that connects to the smoke chamber and is encased in a masonry chimney of necessary height.
More than one flue can be built into the chimney, but each fireplace or other home facility served by the chimney should have its own.
FLUE The flue is a vent that carries the products of combustion out of the house.
Its size governs the volume of smoke it can handle; its height determines the production of draft.
SMOKE CHAMBER This is the space extending from the top of the throat, or damper, up to the bottom of the flue, and between the side walls.
Generally triangular in shape, it serves to funnel the smoke into the smaller area of the flue opening.
SMOKE SHELF A horizontal shelf as wide as the throat and extending back from the top of the throat to the line of the flue wall.
It diverts downdrafts and causes them to eddy into the rising air currents.
DAMPER A metal frame that shapes the throat and is provided with a hinged lid, or valve, to regulate the draft and to close the throat when the fireplace is not in use.
FIREBOX The chamber which actually contains the fire, constructed of firebrick or metal, with the sides splayed and the back sloped to reflect maximum heat into the room.
HEARTH This is the bottom of the firebox, or the area on which the fire is built.
It should be of firebrick or other fireproof material.
Its extension into the room is also called the hearth, and should be a fireproof area not less than the width of the fireplace opening plus 16 inches, projecting at least 16 inches from the chimney breast.
ASH DUMP A metal frame with a pivoted plate, located flush with the hearth surface and usually centered towards the rear.
It is a convenient means by which ashes can be dropped into a pit below.
ASHPIT An ashpit can be built into the fireplace base below the hearth to serve as a storage place for ashes.
CLEANOUT DOOR A necessary opening into the ashpit wall to provide a means of cleaning out the accumulation of ashes.
The door should be of metal and should close tightly.
These are the basic components of most fireplaces.
