General Information:
Calculate the heat loss of the area to be heated. It is recommended that one of the following methods be used: ASHRAE Guide and Data Book ( The  American Society of Heating , Refrigeration & Air Conditioning Engineers) ; The NEMA Handbook ( The National Electrical Manufacturer's Association); or the ACCA Manual J (The Air Conditioning Contractors of America). The layout of the space to be heated must be taken into consideration to determine the selection of the best size and air displacement. Most applications benefit from a combination of vertically and  horizontally  discharged air delivery. In  buildings with large doors that are frequently opened, use  a high  velocity heater with horizontal air flow across the opening, or use an infrared heater.  In smaller areas where comfort is a prime consideration,  more heaters of smaller capacity are recommended. Smaller KW heaters are also recommended 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 12') .

Vertical Air Flow - When vertical discharging heaters are used exclusively, the air streams must overlap to blanket outside walls to 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 Volt. 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 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.


Technical Information:
Heater is constructed of 22 gauge steel for durability and powder coated for a quality finish. Baseboard heaters work best when placed under a window and at least 12" from furniture or other objects. Keep at least 12" minimum from objects hanging above (i.e., drapes). Heater may be placed directly on the floor and mounted to the wall. (Left end wiring only).


Product Dimensions:
16"H x 14"W x 8.25"D

 Ordering Information:
To order units with FACTORY INSTALLED OPTION 24 Volt Control Package, add the following suffix numbers to CEH: Suffix No. - 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, CEH003-R, CEH005-M, CEH005-P, and CEH005-R. Units with the "B" package (whether included or added as an option) require a low voltage thermostat (see T810D - part number 72820).

NOTE: 24 Volt control is needed when controlling several heaters with one thermostat. 24 Volt control is standard on all 480V
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 stat or a CEKTB1 thermostat. USE ONLY C600M, C600S, OR A CEKTB2 FOR 3 PHASE.


** 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)

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