General

The heater is designed for recessed installation in 2” X 4” (50mm X 101mm) stud or larger wall or ceiling sections using the wall box provided. The heater may also be surface mounted by using the Surface Mounting Frame, Model CWHSM or semirecess mounted by using a CWHS1 (for 1” (25 mm) recess frame) or a CWHS2 (for 2” (50mm) recess frame). All three accessories are ordered separately. The heater may be wired with standard building wire (60°C). Refer to specification chart for correct supply voltage and wire size.

For surface or semi-recess mounting, consult Installation Instructions packed with CWHSM, CWHS1, CWHS2.

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.Determine which side of the back box is to be mounted against a stud and bend the tabs at the rear corners out 90 degrees so that the back box will be square with the stud after installation. (See Figure 1).

2.Remove one of the knockouts on socket side of the back box and install a cable or conduit connector.

3.Position back box against side of studs and secure using nails or screws as shown in Figure 1.

NOTE: The back box must be installed with the front edge flush with the finished surface.

4.Run power supply cable through the connector, leaving about 8” of wire inside the box.

5.Connect the supply cable ground wire to green ground screw provided.

NOTE: Lead holes for a #8 sheet metal screw have been provided in the sides of the back box. After the finished wall or ceiling has been put up, drive a # 8(m4) sheet metal screw (recommended 1” long) through the side of the box not mounted to the stud. This will prevent the back box from pulling out when installing the heater assembly. (See Figure 1)

Installation of Back Box in Existing Construction

1.Carefully mark and cut a hole measuring 9-3/8" (235mm) wide by 11-1/8" (283mm) long. One edge of the hole must be cut along the edge of a stud.

AN ELECTRICAL SHOCK, FIRE OR WATER DAMAGE COULD RESULT IF WIRING OR PIPING IS DAMAGED DURING CUTTING. MAKE SURE ALL WIRING AND PIPING ARE CLEAR OF AREA BEFORE CUTTING.

2.Refer to INSTALLATION OF BACK BOX IN NEW CONSTRUCTION section and proceed with steps 1 through 5.

FIELD CONVERSION FOR LOWER WATTAGE RATING

NOTE: Refer to specification chart for lower wattage ratings which are available.

To convert heater to lower wattage rating, completely remove red jumper wire from both heating elements (See Figure 2). Discard this jumper. Be sure remaining wires are securely connected.

DO NOT USE A REMOTE THERMOSTAT WITH THIS HEATER. BUILT IN THERMOSTAT CYCLES THE HEATING ELEMENT ONLY. FAN DELAY CONTROL AUTOMATICALLY TURNS FAN ON AND OFF, AND PROVIDES A FAN DELAY OFF FEATURE TO REMOVE RESIDUAL HEAT AFTER THERMOSTAT HAS TURNED HEATING ELEMENTS OFF. WIRING OF HEATER IN ANY MANNER WHICH DEFEATS THE FAN DELAY OFF FEATURE CAN RESULT IN OVERHEATING AND PERMANENT DAMAGE TO HEATER, AND WILL VOID THE WARRANTY.

Installation and Wiring of Heater / Fan Assembly

1.Following wiring diagram, (Figure 3) connect supply wiring to heater leadwires in back box.

NOTE: For 120 and 277 volt heaters connect the white neutral supply lead to the heaters white pigtail lead, and connect the black supply lead to the heater black pigtail lead. For 208 and 240 volt heaters change the color of the heaters white pigtail lead to black by wrapping with black electrical tape (Most electrical codes require the supply leads to be connected to black leads). Then connect the two black supply leads to the two black receptacle leads.

3.Fit the thermostat knob on to the thermostat shaft and push into place.

OPERATING

INSTRUCTIONS

1.Heater must be properly installed before operation.

2.After heater is completely assembled, rotate thermostat knob counterclockwise until control stops. This is the minimum heat setting.

3.Turn power supply to heater “ON” at main switch panel.

4.Heater should not operate. If it operates disconnect power and recheck wiring.

5.Rotate thermostat clockwise until it stops (maximum heat setting).

6.Heater and fan should come on. If heater and fan do not come on, disconnect power and check wiring.

7.Allow heater to continue to operate until room temperature reaches desired comfort level. Then rotate thermostat knob counterclockwise slowly until thermostat clicks off.

IF FAN SHUTS OFF IMMEDIATELY, THERMOSTAT WIRING IS INCORRECT AND MUST BE CHANGED. FAN MUST DELAY SHUTTING OFF TO EXPEL RESIDUAL HEAT TO PREVENT PREMATURE AGING OF INTERNAL HEATER COMPONENTS THAT COULD LEAD TO A HAzARD OR PREMATURE FAILURE.

8.It 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.

How To Reset Over -Temperature Safety Control:

This heater is provided with an over-temperature safety control with a backup thermal fuse. The safety control will turn on a red warning light, visible through the front of the grille, will illuminate to alert the owner that the heater is off and requires attention.

This control’s reset button is located behind the grille just above the red warning light. The reset button can be seen through the front grille when the heater is installed. To reset, allow the heater to cool, then using an object that will fit through the louvers (such as a small flathead screwdriver), push the reset button that is visible in the fan panel. The heater should immediately return to normal operation. If the alarm light remains on after the heater has cooled and the manual-reset button has been pressed, the thermal fuse may have activated. If this occurs, the heater must be check and repaired by a qualified electrician.

DO NOT TAMPER WITH OR BYPASS ANY SAFETY CONTROL LIMITS INSIDE HEATER.

3

CAUTION - DO NOT CONTINUE TO ATTEMPT TO USE THE HEATER IF THE SAFETY CONTROL REPEATEDLY OPERATES AFTER BEING RESET. TO DO SO COULD PERMANENTLY DAMAGE THE HEATER OR CREATE A FIRE OR SAFETY HAzARD.

Special Note: In addition to the over-temperature safety control, this heater is provided with a back-up thermal fuse (one shot) that will permanently shut the heater off if for some reason the over-temperature safety control should not function as intended. If this thermal fuse activates, the heater will not reset and must be repaired by a qualified repair person
