A heating apparatus can have a sealed combustion chamber and a burner. The heating apparatus can have an air shutter that controls the amount of air that mixes with fuel directed toward the burner. The air shutter can be controlled by rotating a shaft that connects to the air shutter. The heating apparatus can also have a system of channels along its front face which direct air along the front face.

1. A heating apparatus comprising: a sealed combustion chamber, having a front face viewable to a user when the heating apparatus is in use;a burner disposed within said combustion chamber;a combustion air inlet in fluid communication with the sealed combustion chamber and configured to provide air to the burner;an exhaust air outlet in fluid communication with the sealed combustion chamber and configured to remove exhaust air from the combustion chamber;an outer housing surrounding at least a portion of the sealed combustion chamber;a system of channels comprising at least two of a top channel above the front face, a left side channel to the left of the front face, a right side channel to the right of the front face, and a bottom channel below the front face, said at least two of said channels configured to direct air to the front face of the sealed combustion chamber,wherein the at least two channels comprise the bottom channel configured to direct air generally upward, both along the front face and into at least one other channel, the bottom channel having a plurality of outlets comprising a center outlet directing air generally upward along the front face and side outlets that also direct air generally upward along the front face, the side outlets being smaller than the center outlet;at least one fan positioned within the outer housing and configured to direct air into the system of channels; anda control module coupled to the burner and the at least one fan, the control module configured to activate the at least one fan when the burner is in operation. 2. The heating apparatus of claim 1, further comprising a window located behind and substantially parallel to the front face, defining a cooling space between the window and the front face that is located in front of the sealed combustion chamber. 3. The heating apparatus of claim 2, wherein the system of channels is located such that air exiting the system of channels exits into the cooling space. 4. The heating apparatus of claim 1, wherein the center outlet is larger than any other outlet in the system of channels configured to direct air onto the front face. 5. The heating apparatus of claim 4, wherein the side outlets comprise two sets of outlets positioned at an angle from the center outlet and configured to direct air generally upward and to a center of the front face. 6. The heating apparatus of claim 1, wherein the side outlets comprise two sets of outlets positioned at an angle from the center outlet and configured to direct air generally upward and to a center of the front face. 7. The heating apparatus of claim 1, wherein the control module is configured to deactivate the burner when the control module receives an input, or a lack of an input, indicating that the cooling fan is not functioning properly. 8. The heating apparatus of claim 1, wherein the control module is configured to cause the at least one fan to remain activated for a period of time after the burner is deactivated. 9. The heating apparatus of claim 1, further comprising a thermocouple positioned proximate to the front face and configured to sense a temperature of the front face, the thermocouple coupled to the control system such that the control system is configured to cause the at least one fan to remain activated after the burner is deactivated until the front face is cooled to a predetermined temperature. 10. A heating apparatus comprising: a sealed combustion chamber, having a front face viewable to a user when the heating apparatus is in use;a burner disposed within said combustion chamber;a combustion air inlet in fluid communication with the sealed combustion chamber and configured to provide air to the burner;an exhaust air outlet in fluid communication with the sealed combustion chamber and configured to remove exhaust air from the combustion chamber;an outer housing surrounding at least a portion of the sealed combustion chamber;a system of channels comprising at least two of a top channel above the front face, a left side channel to the left of the front face, a right side channel to the right of the front face, and a bottom channel below the front face, said at least two of said channels configured to direct air to the front face of the sealed combustion chamber,wherein the at least two channels comprise a bottom channel configured to direct air generally upward, both along the front face and into at least one other channel, the bottom channel having a plurality of outlets comprising: a center outlet directing air generally upward along the front face; andtwo sets of side outlets positioned at an angle from the center outlet and configured to direct air generally upward and to a center of the front face;at least one fan positioned within the outer housing and configured to direct air into the system of channels; anda control module coupled to the burner and the at least one fan, the control module configured to activate the at least one fan when the burner is in operation. 11. The heating apparatus of claim 10, wherein the system of channels comprises a plurality of air outlets through which air exits the system of channels. 12. The heating apparatus of claim 11, wherein the center outlet is larger than any of the other air outlets of the plurality of air outlets in the system of channels configured to direct air onto the front face. 13. The heating apparatus of claim 10, further comprising a window located behind and substantially parallel to the front face, defining a cooling space between the window and the front face that is located in front of the sealed combustion chamber. 14. The heating apparatus of claim 13, wherein the system of channels is located such that air exiting the system of channels exits into the cooling space. 15. The heating apparatus of claim 10, wherein the control module is configured to deactivate the burner when the control module receives an input, or a lack of an input, indicating that the cooling fan is not functioning properly. 16. The heating apparatus of claim 10, wherein the control module is configured to cause the at least one fan to remain activated for a period of time after the burner is deactivated. 17. The heating apparatus of claim 10, further comprising a thermocouple positioned proximate to the front face and configured to sense a temperature of the front face, the thermocouple coupled to the control system such that the control system is configured to cause the at least one fan to remain activated after the burner is deactivated until the front face is cooled to a predetermined temperature.
