Introduction
The GFK-160A fan has been designed to circulate room
air through the replace to enhance heat output. The
GFK160A fan system operates on 120 VAC, 60 Hz power.
This is available through a receptacle in the factory installed
junction box. The junction box is located in the controls
compartment of the replace.
A variable speed control is provided with the fan system
to provide quiet forced air ow at the desired speeds. A
temperature sensor switch, which automatically turns the
fan ON/OFF, is also provided with this kit.
NOTE: The variable speed control and temperature
sensor switch are not used with some remote control
systems.
NOTE: Some models may have a separate mounting
location on the control panel or valve bracket for mount-
ing this speed control.
2. Slide the temperature sensor switch/bracket assembly
onto the weld stud on the outside of the combustion
chamber. Secure the bracket assembly with the wing
nut provided. See Figure 3.
NOTICE: The weld stud is located either on the lower right
side or the bottom of the combustion box.
Installation Instructions
NOTE: The factory installed junction box in the gas
replace must be wired with 110 VAC before installing
this kit. See Installation Instructions section.
Installing the Fan
Position the fan all the way to the rear and center
in the fireplace. Pull the blower forward 1/8" to 1/4"
from the back wall of the fireplace. See Figure 2.
Thread fan cord plug through hole on bottom of cord bracket
and plug into receptacle labeled "FAN" on power cord.
Installing the Speed Control and Sensor Switch
If using a remote control system that utilizes fan control,
disregard steps 1-3 and follow remote control installation
instructions.
1. Remove the knob and locknut from the variable speed
control. Slide the control behind the replace wall, in,
with the stem sticking out of the pre-punched hole which
is often in the lower right front corner. Attach the lock-
nut tightly and reattach the knob on the stem. Turn the
speed control switch to the "ON" position.
WARNING: Risk of Shock! Turn electrical power off
at the circuit breaker before beginning this installa-
tion.
NOTICE: The switch/bracket assembly must be installed
so that the sensor switch is facing the combustion box
surface.

Recommended Operating Procedures When Variable
Speed Control and Temperature Switch Are Used
Ignite the re in the replace with the variable speed control
switch in an "ON" position. The fan will automatically turn
on when the temperature sensor switch closes at approxi-
mately 110OF. Heated air should be delivered at the outlet
grille. The fan will continue to operate after the replace is
turned OFF until the sensor switch opens.
Various conditions (such as replace model, type of re-
place installation, outside air temperature vs. inside air
temperature) can contribute to the length of the time the
fan remains on after the replace is turned OFF. The fan
can be turned off manually with the speed control switch.
WARNING! Risk of Injury! DO NOT contact fan blades
during operation.
NOTE: The variable speed control and temperature
sensor switch are not used with some remote control
systems.
4. Turn the 110-120 VAC service "ON" at the circuit
breaker.
Maintenance
Periodically check the fireplace louvers, if present,
and controls compartment. Remove any dust, dirt or
obstructions as directed in the appliance Owner's Manual.
