Where should the heating and ventilation grills be located?
The ideal locations for the supply and return grills are in the upper rear (entrance) wall or in the upper rear corners of the side walls or rear end of the ceiling. Sometimes the design of the building will limit where the duct work can be routed and other locations in the court must be used. It would be important to avoid installing grills anywhere in the front (main hit) wall and keep them as high as possible in the court.
