...where to place your CEH heater
...recommendations for horizontal delivery
...the thermostat requirements
...recommendations for vertical delivery
Install the CEH unit heater vertically or horizontally. Brackets are also available for ceiling
mount or wall mount applications.
Heaters should be located so that the air streams of the individual units “wipe” the exposed
walls of the building without blowing directly against the wall. Recommended spacing between
the units is 12 feet. Locate heaters so their air streams are not subjected to interference from
columns, partitions, machinery, etc. (See Figure 1).
For single-phase only, a line voltage thermostat is required for operation. For three-phase, a
two-stage or modulating thermostat is required. A Cadet wall thermostat is recommended for
ultimate control and comfort.
In buildings with high ceilings or bays, vertical delivery unit heaters are recommended to pro-
duce comfort in central areas. They are best used when the perimeter heat loss is adequately
controlled. In combination with horizontally discharged units, they aid in providing good air
mixture (See Figure 3).
Vertical discharging units are mounted high above machinery, assembly lines, etc.
In an application where only vertical discharging units will be used, the air streams must over-
lap to blanket outside walls and provide good heat distribution (See Figure 4).
...some general safety tips
• The ceiling or wall on which the heater is to be mounted must be of adequate strength to sup-
port the heater. Plaster or suspended ceilings will not support this type of heater. For greater
stability, we recommend the use of threaded rods.
• Do not mount the heater where volatile liquids or gases will be present or where it will be ex-
posed to rain or mist. All combustible materials should be kept at least 3 feet away from front
of the heater.
• In an area where the air temperature will be maintained at less than 68˚F, the heater should
be mounted in a position that will not blow directly on people working in the area.
• A minimum clearance for each heater (both horizontal and vertical mount) is listed in Figures 2
and 5. Please follow these recommendations to avoid potential problems with the function and
safety of the heater.
