Use of the GD36 Thermostatic Sensor Control is recom-
mended. With the thermostatic sensor option, the Hot Air
Distribution Fan will become thermally activated.

the sensor assembly
bracket to the securing
stud located next to the
junction box at the bot-
tom left of the unit using
the lock washer and
wing nut. Ensure that the
thermal disc touches the
firebox wall.
2. Using the two wires
(Y) supplied with this kit,
attach the flag ends to the thermal disc and pass both bare
ends through to the inside of the junction box.
3. Route a grounded 2-wire, 60hz power cable to the junc-
tion box. Connect one of the (Y) harness wires to the black
power cable and the other (Y) harness wire to the black wire
from the 14/2 cable running to the variable speed switch.
Connect the white wire to the white power cable wire. Con-
nect the ground wires of both the 14/2 cable and the power
cable to the ground stud located on the fireplace junction
box cover plate.
