A shield is attached to the primary plenum chamber and extends over the secondary plenum chamber. A secondary inlet passageway is formed in an upper portion of the secondary plenum chamber. The secondary inlet passageway fluidly connects the primary plenum chamber to the secondary plenum chamber. A filter member covers the secondary inlet passageway to prevent debris from entering the secondary plenum chamber via the secondary inlet passageway. An outlet passageway is formed in the secondary plenum chamber. The outlet passageway fluidly connects the secondary plenum chamber to the ventilation system.
