Abstract
A termination cap for a direct vent appliance. The termination cap comprises an outer housing, an exhaust housing nested within the outer housing and a trim plate. The trim plate has an exhaust gas opening and combustion air openings and is securable to the exhaust body to allow exhaust gas to flow through the exhaust gas opening. At least a portion of the combustion air drawn through the combustion air openings is heated and exits through the top or upper portion of the trim plate to form an air wash along the wall surface within which the cap is mounted.
