OPTIONAL DISCHARGE OVEN VENT Abstract of the Disclosure A venting system for a food processing oven includes a duct assembly comprising a housing defining an inlet into which heated air from the oven enters and first and second outlets through which the heated air is expelled to the interior or exterior, respectively, of the household in which the oven is installed. A serpentine channel formed by a series of parallel plates mounted in the housing between the inlet and outlets is provided to carry the heated air over a relatively long path to cool, permitting water vapor therein to condense on the plates before the air is expelled. A damper plate is mounted in the housing for pivotal movement in the path between the inlet and second outlet. A manual selector movable to first and second positions is coupled to the damper plate for movement thereof to blocking and unblocking positions, respectively, with respect to the second outlet. Movement of the selector to the first position permits the air to pass to the interior of the household via the first outlet, and movement to the second position permits the air to be discharged via the second outlet to the household exterior. The damper plate is biased normally to the unblocking position. An actuator mechanism coupled between the manual selector and damper plate, controls the position of the latter in response to the operation of the manual selector.
