Abstract
An external intake-discharge duct for a burner-operated refrigerator having a sealed system. The intake communicates with the atmosphere outside of a trailer or a motor home and is located in a service door for the burner of a refrigerating apparatus. Atmospheric air is conducted downward through the air intake to the burner, and hot combustion gases are conducted upwards through a flue pipe and out through a discharge or outlet. The duct terminates in a cap-like structure located externally in a wall of a trailer or motor home.
