         [0013]     The receptacle  70  is moveable relative to the front wall  22  of the fireplace assembly  10  to slide or otherwise move between an open position and a closed position. When the receptacle  70  is in the open position, the receptacle projects from the aperture  83  in the front wall  22  to provide access to the receptacle&#39;s receiving area through the open top portion  81 . In one embodiment, the receptacle  70  is a drawer that is slidably received by the aperture  83  of the fireplace assembly  10 . In other embodiments, the receptacle  70  can be hinged such that it pivotably opens and closes.  
         [0014]     Selected aromatic material  79  can be added to the receptacle  70  when in the open position. The receptacle  70  is then moved to the closed position so that the front wall  72  of the receptacle  70  is immediately adjacent to or flush against the front wall  22  of the fireplace assembly  10 . The remaining portions of the receptacle  70  extend into the aperture  83 , behind the front wall  22 , and adjacent to the firebox  12 . The front wall  72  of the receptacle  72  can include a handle or the like to facilitate opening and closing of the receptacle  70 . The receptacle  70  may be refilled at any time with more or different aromatic material  79 .  
         [0015]      FIG. 3  is a cross-sectional view taken substantially along line  3 - 3  of  FIG. 1 . As best seen in  FIG. 3 , the outer housing  14  includes a bottom wall  26 , a back wall  28 , and a top wall  34 . The fireplace assembly  10  in the illustrated embodiment is a gas-burning unit having a burner assembly  200  contained in the firebox  12 , such as the Ember Fyre® burner assembly manufactured by Travis Industries, Inc. of Kirkland, Wash. In alternate embodiments, the fireplace assembly  10  can be a wood-fueled, pellet-fueled, or electric fireplace, fireplace insert, or free-standing stove.  
         [0016]     The firebox  12  in the illustrated embodiment includes a bottom wall  36 , a back wall  38 , opposing side walls  40 , and a top wall  44 . The firebox  12  is spaced apart from the walls of the outer housing  14  to define a heat exchanger  50  between the firebox and the outer housing. The heat exchanger  50  can include an airflow passageway with bottom plenum  52  disposed between the outer housing bottom wall  26  and the firebox bottom wall  36 , a back plenum  54  disposed between the outer housing back wall  28  and the firebox back wall  38 , and a top plenum  56  disposed between the outer housing top wall  34  and the firebox top wall  44 .  
         [0017]     The heat exchanger  50  is in fluid communication with the air inlet  62  and the air outlet  64  in the front wall  22  of the outer housing  14 . The heat exchanger  50  is adapted to direct an airflow  66  from the air inlet  62 , around the firebox  12 , past the receptacle  70 , and out the air outlet  64 . Heat from the firebox  12  heats airflow  66  as it passes through the passageways of the heat exchanger  50  before the heated airflow  66  is exhausted through air outlet  64 . In some embodiments, the fireplace assembly  10  can include a blower that facilitates the flow of air through the fireplace assembly  10 .  
         [0018]     As the heated airflow  66  passes through the top plenum  56  of the heat exchanger  50 , the heated air and the radiant heat from the firebox  12  heats the receptacle  70  and its contents. The heated aromatic material  79  in the receptacle  70  evaporates and mixes with the airflow  66  before the airflow exits the heat exchanger  50  through the air outlet  64  and into the room where the fireplace assembly  10  is located. In this way, the evaporated aromatic material  79  is diffused throughout the room when the fireplace assembly  10  is in operation to provide aromatherapy to the occupants in the room. In one embodiment, the top portion of the receptacle  70  is open, as described above with respect to  FIG. 2 . The open portion of the receptacle  70  allows the evaporated aromatic material  79  to mix with the heated airflow  66 . In alternate embodiments, a screen or panel with airflow slots can be provided over the top portion of the receptacle  70 . The screen or panel covering the top portion of the receptacle  70  is configured to allow the evaporated aromatic material  79  to leave the receptacle and mix with the heated airflow  66 .  
         [0019]     An alternative embodiment of the present invention is shown in  FIG. 4 , wherein the fireplace assembly  10  is a fireplace insert  100 . The illustrated fireplace insert  100  includes a decorative outer housing  114  that at least partially surrounds a firebox  112 . The outer housing  114  includes a front wall  122 . The front wall further includes an air inlet  162  and an air outlet  164 . In the embodiment illustrated in  FIG. 4 , the front wall  122  of the outer housing  114  is positioned flush against the hearth. In other embodiments, the front wall  122  of the outer housing  114  can protrude outward from the hearth. The fireplace insert  100  is sized to fit within the fireplace cavity in the hearth. Fireplace inserts of various sizes of may be utilized in different embodiments.  
         [0020]     The fireplace insert  100  further includes a receptacle  170  carried by the outer housing  114  and positioned above the firebox  112 . In one embodiment, the receptacle  170  is positioned above the firebox  112 . In alternative embodiments, the receptacle  170  may be positioned at various locations in the fireplace insert  100 . When the receptacle  170  is in the closed position, the front face  172  of the receptacle  170  is flush with the front face  122  of the fireplace insert  100 . The receptacle  170  in the fireplace insert  100  is substantially similar to the receptacle  70  in the embodiments described above with respect to  FIGS. 1, 2 , and  3 .  
         [0021]      FIG. 5  is a cross-sectional view taken substantially along line  5 - 5  of the fireplace insert  100  of  FIG. 4 .
