the side walls of the fireplace. Install blowers with the
blower discharge vent facing upwards and centered on
the blower channel. See Figure 38b.
9. Attach the speed control to the fireplace control compartment floor, farthest to the
front right of the fireplace without interfering with glass latch.
10. The thermal sensor clip is located beneath the firebox floor near the center. Slide the
thermal sensor into the clip until it snaps in place. Make sure the terminals on the
thermal sensor are perpendicular to the clip. See Figure 38c.
11. Unplug the white wire from the blower and plug it into one of the thermal sensor
switch wires. Plug the other thermal sensor switch wire into the open terminal on
the blower (where the white wire was previously located). NOTE: It is important to
arrange the blower wire harness so that wires can not come in contact with blower
fan blades.
12. Plug in the blower.
13. Replace engine in reverse order of removal.
14. To test blower operation, set the variable speed blower on the LOW setting. Turn the
fireplace on high. The blower should turn on within 10 minutes.
15. If the blower does not turn on, turn the fireplace off and allow cooling. Unplug the
blower. Using a jeweler's style screwdriver, turn the white dial on the side of the
variable speed control 1/8 turn counter clockwise. See Figure 38d. This will allow
the blower motor to start at the low speed setting as the fireplace cycles on and off. Retest the blower.
