The kit comes complete with all necessary wiring and  
mounting screws. A wall box plate is included for remote mount-  
ing of the selector switch and can be discarded if the switch is to  
be mounted on the heater.

the correct terminals and the three leads to be wired to other com-  
ponents marked by their respective terminal number, these are  
wire numbers 1, 3 and 9. Before installing the switch, check all  
the wiring connections to be sure none have gotten loose during

inside the wiring compartment. Secure the switch using the on/off  
plate and hex nut (see Figure 3).

on the bottom of the heater by turning the captive latching screw  
90 degrees in either direction (see Figure 1). The selector switch
