- Installation and Operating Instructions -  
1.0 INTRODUCTION  
WARNING: DO NOT CONNECT 110-120 VAC WIRING TO  
THE GAS CONTROL VALVE OF THIS FIREPLACE.  
The GFK-160A Blower has been designed to circulate room  
air through the fireplace to enhance heat output. The GFK160A  
blower system operates on 120 VAC, 60 Hz power. This is  
available through a receptacle in the factory installed junc-  
tion box. The junction box is located in the controls com-  
partment of the fireplace.  
4.0 INSTALLATION INSTRUCTIONS  
4.1 INSTALLING ELECTRICAL SERVICE  
TO THE JUNCTION BOX  
WARNING: TURN ELECTRICAL POWER OFF AT THE  
CIRCUIT BREAKER BEFORE BEGINNING THIS INSTAL-  
LATION.  
A variable speed control is provided with the blower system  
to provide quiet forced air flow at the desired speeds. A tem-  
perature sensor switch, which automatically turns the blower  
ON/OFF, is also provided with this kit.  
1. Remove the electrical cover plate from the lower exterior  
of the fireplace. Remove the knock-out from the plate  
and attach the Romex clamp (screws to the outside).  
(See Figure 2). NOTE: Some fireplace models have a  
round hole through which the service wires are fed and  
into which the Romex clamp is attached. These models  
do not have a cover plate.  
2.0 CHECK CONTENTS OF SHIPPING CARTON  
Compare CONTENTS OF CARTON in Figure 1 with the ac-  
tual parts received. If any parts are missing or damaged,

2. Feed the 110-120 VAC electrical service wires through  
the Romex clamp and secure the wires to the clamp.  
Reattach the cover plate to the outside of the fireplace.  
The GFK-160A Blower Kit is tested and safe when installed  
in accordance with this installation manual. It is your respon-  
sibility to read all instructions before starting installation and  
to follow these instructions carefully during installation to as-  
sure maximum benefit from, and safe operation of, the blower.  
3. Access the controls compartment of the fireplace to lo-  
cate the Junction Box.  
This blower is carefully engineered and must be installed  
only as specified. If you modify it or any of its components,  
you may cause a fire hazard and will void the WARRANTY.  
In addition, such action may void the coverage provided by  
the owner's home insurance.  
4. Using the wire nuts, attach the black wire to the black ser-  
vice wire, the white wire to the white service wire, and the  
service ground wire to the ground stud of the junction box.  
5. Attach the junction box to the side of the unit. Insert the  
rear tab of the box into the rectangular slot in the outer  
wrap of the firebox. Push the front end of the box tightly  
against the side of the unit, and secure the box with a  
sheet metal screw (note the hole in the front end tab).  
CAUTION: All wiring should be done by a qualified electri-  
cian and shall be in compliance with local codes and with  
the National Electric Code ANSI/NFPA NO. 70-current (in  
the United States), or with the current CSA C22.1 Canadian

Periodically check the fireplace grilles and remove any dust,  
dirt or obstructions.

SERVICE  
Various conditions (such as fireplace model, type of fire-  
place installation, outside air temperature vs. inside air tem-  
perature) can contribute to the length of the time the blower  
remains on after the fireplace is turned OFF. The blower can  
be turned off manually with the speed control switch.  
Replacement parts and service may be obtained through  
your dealer.
