the thermal switch (see Figure 18).
9. Connect the black wire to the other side of the thermal switch
(see Figure 18).

tor assembly (see Figure 18). Make sure the thermal switch has
been properly installed to fit against back of fireplace insert af-
ter the rear cover assembly has been reinstalled.
11. Make sure all wire connections to terminals on blower motor
and thermal switch are securely attached and that the screw
retaining the green ground wire is tight.
