LOCATION
It is assumed that the design engineer has selected,
sized, and located in the area to be heated. However,
the information given here may be of additional help to
the installer. These sketches indicate suggested basic
locations for different types of unit heaters.
Horizontal unit heaters should be located to give a
circulatory motion, preferably in the outer perimeter of
the building. The units should be spaced to properly
blanket the areas with warm air.
The unit should be suspended from connections
provided in the unit by means of rods. The rods should
then be attached to solid supports of the building.
