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 26,
page 17).
4. Be certain that all wire terminals are securely
attached to terminals 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 27).
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 pro-
vided on shaft.
7. Turn on power to duplex outlet if previously
turned off per the warning in column 2, page 17.
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 com-
pletely 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 counterclock-
wise before continuing.
10. Peel off the backing paper and stick the sup-
plied wiring diagram decal on the firebox bot-
tom approximately 12" in front of the blower
(see Figure 28).

Model BKT Installation
Note:
When installing the BKT thermostati-
cally-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 termi-
nal 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 29, page 19).
2. Connect wire harness and power cord ter-
minals. Connect the blue jumper wire to the
blower motor terminal and the right side ter-
minal 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.
