gular hole to front of fireplace (see Figure 14).
8. Reconnect red wire to switch position 3.
Reconnect blue wire to switch position 1.
Reconnect green and white wires.
9. Install the switch plate on the remote/blower
bracket with 2 #10 screws provided (see Figure
16). Route power cord out of the cabinet by
inserting it through the bushing on the outer
casing (see Figure 14). Plug fan kit into 120-
Volt grounded power supply and test operation.
Note: When switch is in the AUTO position,
the fan will start after the fireplace has run for a
few moments. The fan will continue to run for
several moments after the fireplace has been
turned off. When switch is in the ON position,
the fan will run until turned to OFF.
