Rooftop hvac unit

Abstract

A rooftop unit (RTU) having a power exhaust component is disclosed. The RTU comprises a sliding mechanism configured to support the power exhaust component and enable movement of the power exhaust component between a stowed position, and an unpacked position. Further, an RTU having furnace assembly is disclosed. The RTU comprises a sliding mechanism configured to support the furnace assembly and enable movement of the furnace assembly between a stowed position, and an unpacked position. Furthermore, an air-directing baffle for an electric heater associated with an RTU is disclosed. The baffle is adapted to be removably configured between the electric heater and fan(s) associated with the RTU. The baffle directs the flow of air towards a limit switch and/or heating elements associated with the electric heater while restricting the recirculation of the air towards the fans or within the RTU.
