The framework assembly has a fireplace firebox, an oven firebox, a smokebox, and a chimney flue disposed therein. Each of the fireplace firebox and the oven firebox is in communication with the smokebox. The smokebox is in communication with the chimney flue. The framework assembly is covered by a refractory heat resistant mortar. The oven firebox is suspended above the fireplace firebox and is configured for baking pizza. The smokebox and the chimney flue are disposed in the framework assembly above both the fireplace firebox and the oven firebox. ## Claims ### Claim 1 A combination outdoor fireplace and pizza oven system, comprising: a main body including a framework assembly having a fireplace firebox, an oven firebox, a smokebox, and a chimney flue disposed therein, each of the fireplace firebox and the oven firebox in communication with the smokebox, and the smokebox in communication with the chimney flue, the framework assembly covered by a refractory heat resistant mortar, the main body further including a base disposed beneath the fireplace firebox and configured to facilitate a transport of the combination outdoor fireplace and pizza oven system, wherein the oven firebox is suspended above the fireplace firebox and configured for baking pizza, and the smokebox and the chimney flue are disposed in the framework assembly above both the fireplace firebox and the oven firebox, wherein the base includes a pair of holes formed in a front wall of the base, the pair of holes configured to receive at least one of forklifts, slings, and straps for lifting and positioning the combination outdoor fireplace and pizza oven system, and wherein the holes are defined by a pair of box-iron channels connected to the framework assembly and projecting outwardly from the main body to define a step of the combination outdoor fireplace and pizza oven system. ### Claim 2 (depends on 1) The combination outdoor fireplace and pizza oven system of claim 1, wherein the fireplace firebox is in communication with smokebox through at least one flue duct. ### Claim 3 (depends on 2) The combination outdoor fireplace and pizza oven system of claim 2, wherein the at least one flue duct includes a first flue duct and a second flue duct, the first flue duct disposed between the oven firebox and a first sidewall of the main body, and the second flue duct disposed between the oven firebox and a second sidewall of the main body. ### Claim 4 (depends on 2) The combination outdoor fireplace and pizza oven system of claim 2, wherein the at least one flue duct includes a single flue duct disposed between the oven firebox and a rear wall of the main body. ### Claim 5 (depends on 1) The combination outdoor fireplace and pizza oven system of claim 1, wherein the framework assembly includes a framework of steel channel members. ### Claim 6 (depends on 5) The combination outdoor fireplace and pizza oven system of claim 5, wherein the framework of steel channel members define chambers for the fireplace firebox and the oven firebox. ### Claim 7 (depends on 6) The combination outdoor fireplace and pizza oven system of claim 6, wherein each of the fireplace firebox and the oven firebox comprises noncombustible magnesium oxide board and refractory bricks. ### Claim 8 (depends on 7) The combination outdoor fireplace and pizza oven system of claim 7, further comprising mineral wool insulation disposed in the steel channel members between the magnesium oxide board of the fireplace firebox and the magnesium oxide board of the oven firebox. ### Claim 9 (depends on 1) The combination outdoor fireplace and pizza oven system of claim 1, wherein each of the fireplace firebox and the over firebox has an opening at a front wall of the main body. ### Claim 10 (depends on 9) The combination outdoor fireplace and pizza oven system of claim 9, wherein the opening of the oven firebox is selectively closed by an oven door hingedly attached to the front wall of the main body. ### Claim 11 (depends on 10) The combination outdoor fireplace and pizza oven system of claim 10, wherein the smokebox is configured to collect smoke and hot gases from both the fireplace firebox and the oven firebox and to reduce an airspace cross-section to a choke-point that transitions into the chimney flue. ### Claim 12 (depends on 11) The combination outdoor fireplace and pizza oven system of claim 11, wherein the reduced airspace cross-section of the smokebox aides in creating a higher pressure above the choke-point relative to a lower pressure within the fireplace firebox in operation to draw the smoke and the hot gases through the smokebox and into the chimney flue. ### Claim 13 (depends on 1) The combination outdoor fireplace and pizza oven system of claim 1, wherein the refractory heat resistant mortar includes fireclay, cement, and sand. ### Claim 14 A combination outdoor fireplace and pizza oven system, comprising: a main body including a framework assembly having a fireplace firebox, an oven firebox, a smokebox, and a chimney flue disposed therein, each of the fireplace firebox and the oven firebox in communication with the smokebox, and the smokebox in communication with the chimney flue, the framework assembly covered by a refractory heat resistant mortar, wherein the oven firebox is suspended above the fireplace firebox and configured for baking pizza, and the smokebox and the chimney flue are disposed in the framework assembly above both the fireplace firebox and the oven firebox, and wherein the smokebox is defined by an area above a dome of the oven firebox and a lower wall of the chimney flue. ### Claim 15 (depends on 14) The combination outdoor fireplace and pizza oven system of claim 14, wherein the dome is formed by a plurality of interlocking bricks disposed in an arch. ### Claim 16 A combination outdoor fireplace and pizza oven system, comprising: a main body including a framework assembly having a fireplace firebox, an oven firebox, a smokebox, and a chimney flue disposed therein, each of the fireplace firebox and the oven firebox in communication with the smokebox, and the smokebox in communication with the chimney flue, the framework assembly covered by a refractory heat resistant mortar, wherein the oven firebox is suspended above the fireplace firebox and configured for baking pizza, and the smokebox and the chimney flue are disposed in the framework assembly above both the fireplace firebox and the oven firebox, wherein the fireplace firebox is in communication with the smokebox via one of a first flue duct and a second flue duct, wherein the first flue duct is disposed between the oven firebox and a first sidewall of the main body and the second flue duct is disposed between the oven firebox and a second sidewall of the main body, and a single flue duct disposed between the oven firebox and a rear wall of the main body, and wherein the smoke box is defined by an area above a dome of the oven firebox and a lower wall of the chimney flue.
