THAT THE WORD "HEARTH" is synonymous with "home" in many languages is not surprising since much of the enjoyment of home and camp life centers about an open fire. In mild climates a properly built fireplace will heat a single room, and when equipped with a convection heater will also heat a second room on the same floor or an upper floor. In colder climates it is a useful adjunct to other heating systems if provided with a damper.
This bulletin is intended to give the householder and prospective builder, especially the farmer who might superintend the construction of his home, a working knowledge of the principles to be observed in planning and building fireplaces and chimneys. These principles, if observed, will make the structures useful and satisfactory and insure their safety.
Safe fireplaces and chimneys that function properly can be built by applying the principles given in this bulletin, but a good chimney will not last indefinitely without proper care and repair.
Fireplaces and chimneys, being conspicuous architectural features, should be pleasing in appearance and conform with the general design of the building and its surroundings.
This bulletin supersedes Farmers' Bulletin 1649, Construction of Chimneys and Fireplaces.

FIREPLACES AND CHIMNEYS should provide a safe place for an open fire and a flue for draft to expel smoke from the fire passage to the open air. They must be properly designed and constructed (fig. 1) if good performance and protection against fire are to be obtained.
