Abstract

A direct venting system for a free-standing propane powered refrigerator is disclosed. The direct venting system pre-installed on the refrigerator, the system having an air intake for drawing air from outside and directing the air to a burner box for combustion of the propane gas flame that runs the refrigerator, and an exhaust outlet for venting all of the flue gases or products of combustion out of the system with the system being hermetically sealed with respect to an interior environment within which the refrigerator is installed. The fresh air is directed to a burner box by means of a specially designed air inlet adapter that includes a step-down feature that reduces the likelihood of blow-out of the gas flame. The flue gases are directed through an offset chimney structure and a three-layered exhaust outlet that reduces the formation of condensate thereby protecting the system from blow-out and corrosion.
