ABSTRACT:
A gas downdraft range is provided with an airflow system for inducing and maintaining cooling airflow, combustion airflow and exhaust airflow. A housing defines an upwardly facing burner box and a cover overlies the housing with a downwardly formed burner pan disposed within the burner box. The bottom wall of the burner pan is spaced above the bottom wall of the burner box to form an air space therebetween. The burner box has cooling air inlets and cooling air outlets in communication with the air space to define a cooling airflow path. A burner is operably disposed in the burner pan and a grill grate overlies the burner pan providing combustion air inlet and outlet ports to and from the burner pan for defining a combustion airflow path. A plenum enclosure is connected to an exhaust air intake juxtaposed the grill grate and exhausts to atmosphere defining an exhaust airflow path. A blower concurrently induces and maintains each of the airflows.
