Installation and Wiring of Heater / Fan Assembly
NOTE: For installations over 7500 ft. above sea level we recom-
mend using heaters with wattages under 1500 watts. Models with -IF suffix do not include a built-in thermostat. A 2 pole ther­mostat kit model CZTDP is available if desired or a remote line voltage wall thermostat may be used.
1. Following wiring diagram (Figure 2) connect supply wires to heater leadwire in back-box using appropriate wire connec­tors.
NOTE: For 120 volt heaters, connect the white neutral supply lead to the heater’s white lead (or colored lead marked with “N”), and connect the black power lead to the heater’s black lead.
For 208 /240 volt heaters (with two hot power leads), if either power lead is white in color, change the color of the lead by wrapping with black electrical tape (Most electrical codes require the power supply leads to be black (non-white) in color). Connect the two black power leads to the heater’s black (or black and red) leads.
2. Secure supply ground wire under green ground screw in back-box.
3. Fit heater/fan assembly into back-box fitting bottom section into two tabs provided and securing top to back-box with screw provided.
TO CHANGE WATTAGE OUTPUT
Your heater is provided with a clip out wire that will allow the heater wattage output to be permanently reduced to 1/2 wattage if desired (see Fig. 3). If wattage is changed to a reduced wattage, installer must also check the appropriate box on label in back-box. See instructions on how to reduce wattage located on back side of fan panel.
OPERATING INSTRUCTIONS
NOTE: All heaters are intended to be controlled by a thermostat.
The below instructions are for units with a built-n thermostat. If remote wall thermostat is provided, refer to the instructions pro­vided with this control for proper operation.
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.
8. It may be necessary to readjust thermostat a couple of times 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.
CLIP-OUT WIRE
