Form I-UDA, P/N 195673 R24, Page 5
Locate the heater so that it is a minimum of ve feet (1.5M) above the oor and in
compliance with the clearances in Paragraph 4.1.
WARNING
If touched, the vent pipe and internal heater surfaces that are
accessible from outside the heater will cause burns. Suspend the
heater a minimum of 5 feet (1.5M) above the oor.
For best results, the heater should be placed with certain rules in mind. In general, a
unit should be located from 8 to 12 feet (2.4-3.7M) above the oor. Units should always
be arranged to blow toward or along exposed wall surfaces, if possible. Where two or
more units are installed in the same room, a general scheme of air circulation should
be maintained for best results.
Suspended heaters are most effective when located as close to the working zone as
possible, and this fact should be kept in mind when determining the mounting heights
to be used. However, care should be exercised to avoid directing the discharged air
directly on the room occupants.
Partitions, columns, counters, or other obstructions should be taken into consideration
when locating the unit heater so that a minimum quantity of airow will be deected by
such obstacles.
