The FK-180-ESC Fan Kit has been designed to circulate room air through many hearth products in the industry. The FK-
180-ESC operates on 120VAC, 60Hz power. The fan dimensions are 12-3/4” W x 4-3/8” H x 4-5/16” D.
Power must be provided through an approved factory installed junction box from the hearth product’s manufacturer.
A speed control (FK-ESC) is provided with the Fan Kit System to adjust the air output. The speed control will turn ON the
fan automatically 7 minutes after the main ame has been turned ON and turn the fan OFF 12 minutes after the main
ame has been turn OFF. There are four speeds, Hi, Medium Hi, Medium Lo, Lo and OFF. You can manually adjust the
speed by pressing the FAN SPEED button on the FK-ESC. The FK-ESC will remember the last setting used and remain
on that setting until changed.
Compare the contents of your package with the gure drawings below.
1. F-180-1 Fan with two leads and a ground wire
2. FK-ESC (speed control)
3. Jumper Wire (used for IPI valves only)

INSTALLATION
WARNING: Turn electrical power OFF at the circuit breaker before beginning
this installation.
1. Unplug the old fan system (if applicable) and remove it from the appliance.
2. Attach the FK-ESC wires to the F-180-1 fan as shown in the wiring diagram below.
3. Install the new F-180-1 fan housing in the rear of the appliance where the previous
fan was installed.
4. Pull the fan housing slightly away from the metal back wall (1/8’’ to 1/4’’) of the
appliance. The magnetic feet will hold the housing in place. (See Fig. 1)
5. Attach the F-180-1 fan ground (green) wire to an accessible ground source.
6. Plug the FK-ESC into an approved electrical junction box and lay inside appliance
accessible for operation.
7. If installing this kit into an appliance with a Millivolt valve system use gure #2. If
installing this kit into an IPI electronic system use gure #3. Fig 1. Side View

WIRING NOTES: IPI System - When wiring an IPI system the Sense – (black) wire must be secure
to a ground on the gas valve or to metal on the appliance for proper operation.
POWER SOURCE INFORMATION
When plugging in the FK-ESC into a 120VAC power source some replaces use a standard metal junction box and other
replaces may use a power strip. If a power strip is used (as shown below in gure 4) and no power is found in the FAN
outlet use the red jumper wire with the 1/4” connectors and attach as shown below. With the jumper installed the FAN
outlet will provide the power necessary to operate the FK180-1 system.

MAINTENANCE
Cleaning on a semi-annual basis is required to keep the warranty in place. Dust or dirt must be removed from the fan
blades, air inlets and blower outlet for the fan kit to maintain the ef ciency of the system. Carefully use a vacuum with a
brush to remove any dust. If unable to reach fan with a vacuum remove the fan from the appliance for easier cleaning.
