A fireplace insert comprising a trapezoidal firebox (1) with slanted walls (24) and a smoke chamber (2) placed above the firebox (1), has a grate (13), a firebox mantel (4) providing the outside border of the firebox (1), and a noncombustible lining (5) providing inside covering of the firebox (1). Further it has a screen opening with a glass door (6) in its front part, an adjustable primary air intake (7) in the ash-dump (11) below the grate (13) and above the door (6), an adjustable secondary air intake (8) channelled to the upper part of the door (6). In the side walls (24) and/or the back wall (23) of the firebox (1), the fireplace insert has tertiary air intakes (18) disposed preferably in equipartition approximately halfway up the walls (23, 24), as well as air intakes for afterburning (19) disposed preferably in equipartition at approximately the upper third of the height of the walls (23, 24). The smoke chamber (2) comprises a tortuous smoke outlet (22) formed by the back wall (23), a flame deflector (20) and a parallel higher mounted smoke damper (21).
