- 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,

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

5.0 RECOMMENDED OPERATING
PROCEDURES
WARNING: NEVER CONTACT BLOWER WHEEL (VANES)
DURING BLOWER OPERATION.
Ignite the fire in the fireplace 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 110O F. Heated air should be delivered at the outlet
grille. The fan will continue to operate after the fireplace is
turned OFF until the sensor switch opens.
6.0 MAINTENANCE
Periodically check the fireplace grilles and remove any dust,
dirt or obstructions.
7.0 REPLACEMENT PARTS AND CUSTOMER
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.
