3. Place the blower against the lower rear wall of the firebox outer
wrapper with the exhaust port directed upward. The blower will
fit inside the back opening and be held in position against the
back wall by the magnets (see Figure 25).
4. Be certain that all wire terminals are securely attached to ter-
minals on blower motor and that the screw retaining the green
ground wire is tight.
5. Mount speed control box to switch bracket by placing the plastic
control shaft forward through the opening in the switch bracket
(see Figure 26).
6. While supporting speed control, secure control shaft with lock
nut by pushing and turning lock nut with pliers clockwise until
it is tight against front panel. Place control knob provided on
shaft.
7. Turn on power to duplex outlet if previously turned off per the
warning in column 2, page 14.
8. Plug in blower power cord.
a. If your firebox is installed as a freestanding unit with an
accessory mantel, determine whether the power cord will
exit the left side or the right side of the firebox. Route power
cord through exit hole and plug the power cord into a wall
receptacle near the firebox.
b. If your firebox installation is recessed and/or pre-wired, plug
the power cord into the duplex outlet provided. Refer to your
firebox owner’s manual for instructions on wiring the duplex
outlet.
CAUtION: Never touch the blower wheel while in
operation.
9. Check to make sure that the power cord is completely clear of
the blower wheel and that there are no other foreign objects in
blower wheel. Turn blower on and check for operation. Turn
blower off by turning knob fully counterclockwise before
continuing.
10. Peel off the backing paper and stick the supplied wiring diagram
decal on the firebox bottom approximately 12" in front of the
blower (see Figure 27).

Model bKT Installation
Note: When installing the BKT thermostatically-controlled blower,
you must first secure the thermal switch bracket to the blower if it
has not already been factory installed.
1. Place the green ground wire with ring terminal between the
bottom hole on the thermal switch bracket and the top ear hole
on the blower assembly. Insert the Phillips screw into all three
pieces and tighten securely (see Figure 28, page 16).
2. Connect wire harness and power cord terminals. Connect the
blue jumper wire to the blower motor terminal and the right
side terminal of the thermal switch. Connect the black wire to
the left side of the thermal switch and the white wire to the
other remaining blower motor terminal.
Note: The power cord outer insulation sleeve may have to be
stripped slightly to allow enough wire length to reach and make
all connections. DO NOT trim excessive length away. Just enable
enough to make all connections securely.
