General Information (continued):
nded for low mounting heights to avoid discomfort and increased noise levels. Additionally, there is better air distribution by using a greater number of lower KW heaters.

Horizontal Air Flow – Position heaters to allow the air flow to "wipe" the exposed walls without blowing directly against the wall. Spacing between the heaters should be approximately 1.5 times the "air throw" of the heaters (approx. air throw is 12').

Vertical Air Flow – When vertical discharging heaters are used exclusively, the air streams must overlap to blanket outside walls and provide good heat distribution. Vertical air flow is best used for areas with high ceilings or bays. Vertical discharging units are to be mounted high above machinery, assembly lines, etc. Vertical discharging units are best used when the perimeter heat loss is adequately controlled.

Architectural Information:
Fan forced unit heater shall be UL Listed and rated at 208, 240, 277 or 480 Volts. Horizontal or vertical mounting shall be possible to direct discharged air. External cabinet shall be constructed of 20 gauge high quality steel. All metal surfaces of the cabinet, external and internal, shall be finished with a baked on powder coat paint system. Fan shall be aluminum blade axial flow type, and mounted directly to the motor shaft. Motor shall be shaded pole, industrial rated, with an inherent overheating protection device. Heating elements shall be sealed in magnesium oxide powder and protected by metal sheathing, over which aluminum fins are applied. Heater shall be equipped with manual reset thermal cut out for over temperature protection. Fan motor circuit shall be thermostatically controlled, allowing fan to remain operating after the elements have shut off, discharging the residual element heat. Wiring compartment shall have convenient access door with captured hardware.

Ordering Information:
To order units with factory installed optional 24 volt control package, add the following suffix numbers to CEH Model: B. The 24 volt control package includes a transformer and contactor. It is required to change from line voltage control to 24 volt control for the following model numbers: CEH003-M, CEH003-P, CEH005-M, and CEH005-P. Units with the "B" package (whether standard or added as an option) require a low voltage thermostat (see T810D - part number 72820). The 24 volt control is standard on 480 volt models.

NOTE: 24 volt control is needed when controlling several heaters with one thermostat. 24 volt control is standard on all 480 volt models.

Ordering Example:
CEH003-MB (Includes 24 volt control package)

* Models CEH003-M, P, R and CEH005-P, R (1 Phase) are designed to use a C600M, C600S or a CEKTB2 thermostat. If you add the jumpers, as shown on the heater wiring diagram (supplied with instructions and in wiring compartment) you can use a Single Pole 22 amp wall stat or a CEKTB1 thermostat. USE ONLY C600M, C600S, OR A CEKTB2 FOR 3 PHASE hookup on these models.

** When using model number CEH-005-M wired 1 phase (factory wired) use the following thermostats: Wall Mount – C611-25, Built-In – CEK-TB2 (two-stage thermostat). Use only CEKTB2 when wiring 3-phase.

Approximate air throw is 12'. The CEH is recommended for elevations under 7500 feet
