Abstract
The present teachings provide for an HVAC assembly including a housing and a door. The housing can define a first flue. The first flue can be configured to direct a first airflow through the housing. The door can be received in the housing and can be movable between a first position and a second position. The door can have an edge and an upstream surface. The edge can form a seal with the housing when the door is in the first position. The edge can be spaced apart from the housing when the door is in the second position. The upstream surface of the door can define a plurality of channels proximate to the edge of the door.
