What describes the configuration of a "Hi Boy" forced air gas furnace?

The correct description of a "Hi Boy" forced air gas furnace is that supply air exits at the top and return air enters at the bottom. This configuration allows for effective circulation of air throughout the space being heated. With the supply air coming out from the top, it efficiently rises into the living areas, promoting even distribution of warm air. The design facilitates a natural flow where the cooler air is drawn back into the furnace from the lower part of the space, maintaining a continuous cycle of heating.

This operational principle is important in ensuring that the furnace performs effectively, making it a common choice in residential heating systems. The layout also allows for optimal efficiency and comfort, as heat rises and cooler air is properly managed.
