IMPORTANT: OWNER SHOULD RETAIN THESE INSTRUCTIONS FOR FUTURE REFERENCE
INSTALLATION
INSTRUCTIONS
Location of Heater:
Heaters are designed for surface, recessed or “T-bar”
ceiling mounting. Heaters must be mounted to provide
a minimum clearance of 8” from the intake or exhaust
end or from the sides of the heater to the nearest wall
or obstruction. For T-Bar installation (Fig. 3), use the
optional T-Bar frame CEH-TBF / TB3380. Select a 2’x 2’
section of framework in such a location that the mini-
mum 8” spacing is maintained. Follow the installation
wiringdiagramcarefully.Agreengroundleadisprovided.
Insurethatsupply voltage matches voltage ratingonthe
labelof the heater.Disconnect power supply at breaker
boxbeforeinstallation.
MountingInstructions:
1. Disassemble heater as shown in Fig. 1 & Fig. 2.
2. Flush Mounting (Fig. 2). Provideopening in ceiling
14 1/4” wide by 19 5/16” long. Note that the direction
of air flow is parallel to the 19 5/16” side of the
opening. Depth must be a minimum of 4” from the
finishedceiling surface. Install rough-in boxinto the
openingso that the flanges are flush with finished
ceilingsurface. Secure rough-in boxwith nails,
screwsor appropriate fasteners. Wiring maybe
broughtinto the box from either end using the
knockoutsprovided.
3. SurfaceMounting(Fig. 1). Insert rough-in boxinto
surfaceadapter CEHA /3380EX33.Securerough-in
boxinto ceiling through holes provided in the back.
Be sure that rough-in box is centered in the surface
adapter. Bring wiring in through air outlet end knock
outs only.
4. Remove all construction dirt and debris from inside
the heater.
5. Place heater assembly inside the rough-in box and
secure with six screws.
WiringInstructions:
6. All wiring must conform to National and local
electrical codes.
With Disconnect Ref. WD-1
A. Attach service leads to two black leads (L1 & L2)
on208-240voltmodels and to white (L1) and
black(L2)on120-277voltmodels,withapproved
connectors.Connectgroundleadtogreenground

B. Runserviceleads from remote thermostat and
connecttoleadwire T1 & T2 withapproved
connectors.Replacewiringcompartmentcover.
Without Disconnect Ref. WD-2
For proper fan operation, three conductor wires and a
ground wire must be used between the thermostat and
the heater. For 277 and 120 volt applications use a
white, black, red and ground combination. For 208 and
240 volt applications use a black, black, red and ground
combination. The wiring diagram is color coded in this
manner.
For 120 and 200 Volt Operation:
Connect the white (neutral) supply lead to the red pigtail
lead, the black supply lead (L2) to the black pigtail lead,
and the red supply lead (L2) to the blue pigtail lead. The
ground wire should be connected to the green pigtail
lead.
For 208 and 240 Volt Operation:
Connect the black supply lead (L1) to the red pigtail
lead, the black supply (L2) to the black pigtail lead, and
the red supply lead (L2) to the blue pigtail lead. The
ground wire should be connected to the green pigtail
lead. Replace wiring compartment cover.
7. Attach front grille with four screws.
Note: The wall thermostat cycles the heating element
only. Direct runs of supply service leads L1 & L2 supplies
continuouspower to the fan motor,andthe heater should
be considered live at all times. Move the disconnect
switch to off position or disconnect power at main distri-
butionboxbeforeanymaintenancework.Turning the
thermostat to off position will not disconnect the heater.
Form 9585

OPERATION INSTRUCTIONS:
External Thermostat
Thethermostat should be mounted at the level of the
desired comfort zone, but not in the direct path of the
heated discharge air. A single pole thermostat with
anticipator is recommended. Be sure that the ratings
of the thermostat are sufficient to carry the heater
load.
Fan Operation
This heater is equipped with a fan delay control. When
the thermostat calls for heat, the fan control delays the
fan operation until the element is fully hot. Then the fan
will energize and operate.After the thermostat is
satisfied,the element will de-energizeand the fan will
continue to run until the element has cooled down. If
the fan does not function in this manner, check all
wiringconnectionsagainstthe wiring diagram.
MAINTENANCEINSTRUCTIONS:
Once a year, disconnect electrical power at source.
Removefrontgrilleandcleandustfromheater and
grille. Lubricate the motor with SAE No. 10 oil. Two oil
spouts are located on front and back of motor. Once
finishedturnpower back on toheater.
