Installation Instructions
The optional FK24 fan kit is designed to be installed in
most CFM Corporation gas fireplaces. Please refer to
the Installation Instructions provided with the fireplace
the fan kit is to be installed in for additional information.
NOTE: Make sure all power to the electrical supply
has been turned off prior to beginning the installa-
tion.
1. Hold the fan assembly so that the mounting bracket
faces downward and the fan motor is furthest away
from the fireplace. Slide the assembly through the
access door on the left side of the valve control
compartment.
Turn the assembly ninety degrees around the valve
so that it is parallel to the back. Next rotate the
assembly so that the mounting bracket is turned up
facing the back of the fireplace. Line up the bracket
mounting holes with the screw studs on the back of
the fireplace and fasten with #10-24 hex nuts.
2. Insert fan temperature sensor into retainer sensor
box, then secure retainer sensor box onto the burner
base with #10-24 hex nuts. (Fig. 1)
3. (Option A) - Place electronic fan speed control box
on bottom of fireplace base, lining up mounting
holes with screw studs. Fasten fan speed control
box with #10-24 hex nuts.
(Option B) - The speed control can be installed in
an electrical box at normal switch height for
convenient access.
4. If using existing cord, plug in to the electrical box
(EB1) (See EB1 instructions for installation).
5. For direct wiring remove junction box cover and
disconnect the electrical cord. Remove electrical
knockout on the side of the fireplace and feed
electrical wires through the side and into the junction
box. Connect ground wire to ground stud located on
the base of box. Black wire from supply should
connect to the variable speed switch. Alternate
speed switch wire connects to temperature sensor.

This fan does not need regular maintenance,
however periodic cleaning is required. Check the
