- Installation and Operating Instructions -

1.0 INTRODUCTION

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 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.
