This fireplace cutaway shows the relationships between the firebox (which is constructed of fire brick laid in fireclay mortar), smoke shelf, smoke chamber with parging, and flue, with required separation from combustible materials. The fireplace face is defined by the vertical distance between the damper and the lintel supporting the face brick across the fireplace opening. The detail also shows a fresh air intake, ash pit, and a raised hearth with required support.
