GFK-100 BLOWER SYSTEM
1.0 INTRODUCTION
The GFK-100 Blower has been designed to circulate room air through the fireplace to enhance
heat output.
The GFK100 blower system operates on 120

receptacle in the factory junction box. The junction box is located in the controls compartment of the fireplace.
A variable speed control is provided with the
blower system to provide quiet forced air flow
at the desired speeds. A temperature sensor
switch, which automatically turns the blower
ON/OFF, is also provided with this kit.
