GENERAL
•The C series heaters are designed for recessed installation in 2 X 4 stud or
larger wall using the model CBB (Type CO2-BB) back box. The heater may
be wired using standard building (60 degrees C minimum) wire.
•The optimum mounting height for this heater is 18” to 24” (457mm to
610mm) from floor to bottom of back box. In any case, do not install closer
than 4.5” (114mm) from the floor or adjacent wall.
Ceiling Mount
•The C Series heaters are designed for ceiling mount provided the wattage
does not exceed 1000 watts. In order for your heater to be rated for
ceiling application, the heater must
be trimmed back to 1000 watts or less.
(See Change Wattage Output below)
•The optimum clearances to any wall surface are 12 inches. Do not mount
heater in the ceiling if these clearances are not met.
•Ceiling heaters can be recessed or surfaced mounted.
Heaters are also approved for semi-recessed or surface mounting on walls. Refer to
instructions for installations of the CSM Surface Mounting frame.
INSTALLATION OF BACK BOX
IN NEW CONSTRUCTION
NOTE: If the finished wall surface is already up, follow instructions for
“INSTALLATION OF BACK BOX IN EXISTING CONSTRUCTION”.
1. Allow for the thickness of the finished surface when installing the back
box. The edge of the back box must be installed flush with the finished
surface. Markings on the side of the back box for 1/2” or 5/8” finishing
wall are provided.

INSTALLATION OF FRONT COVER (GRILLE) AND
THERMOSTAT KNOB
1. Fasten front cover to heater assembly using the (2) long
screws supplied.
2. Fit the thermostat knob onto the thermostat shaft (if provided)
and push into place.
HEATER CHECKOUT AND OPERATION
1. After heater is completely assembled, rotate thermostat knob
counterclockwise until control stops. This is the minimum heat
setting.
2. Turn power supply to heater “ON” at main switch panel.
3. Heater should not operate. If it operates disconnect power and
recheck wiring.
4. Rotate thermostat clockwise until it stops (maximum heat setting).
5. Heater and fan should come on. If heater and fan do not come
on, disconnect power and check wiring.
6. Allow heater to continue to operate until room temperature
reaches desired comfort level. Then rotate thermostat knob
counterclockwise slowly until thermostat clicks off.
7. If may be necessary to readjust thermostat a time or so until
exact comfort level is attained. Rotation in the clockwise direction will increase the amount of time the heater will produce
heat. Rotation in the counterclockwise direction will reduce the
amount of time the heater is on.
NOTE: For best results, the heater should be left “ON” constantly during the
heating season as the thermostat, when properly set, will maintain the desired
temperature. In the full counter-clockwise position the heater will remain off
until the room temperature drops well below freezing.
(If internal thermostat provided)
MAINTENANCE
!
TO REDUCE RISK OF FIRE AND ELECTRIC SHOCK, DISCONNECT ALL
