Model BKT Installation
Note: When installing BKT thermostatically-
controlled blower, you must first secure
thermal switch bracket to blower if it has not
already been factory installed.
1. Place green ground wire with ring terminal
between bottom hole on thermal switch
bracket and top ear hole on blower assem-
bly. Insert phillips screw into all three pieces
and tighten securely (see Figure 28).
2. Connect wire harness and power cord ter-
minals. Connect blue jumper wire to blower
motor terminal and right side terminal of
thermal switch. Connect black wire to left
side of thermal switch and white wire to
other remaining blower motor terminal.
Note: 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.
3. Place blower against lower rear wall of firebox
outer wrapper with exhaust port directed
upward and thermodisc positioned up near
fireplace bottom. Thermodisc must be oriented
near fireplace bottom as shown in Figure 28
in order to sense temperature and properly
operate. Blower will be held in position against
back wall by magnets incorporated onto
blower housing (see Figure 28).

4. Be certain that all wire terminals are
securely attached to terminals on blower
motor and thermal switch, and that screw
for thermodisc bracket and green ground
wire is tight.
5. Mount speed control box against mounting
plate provided in lower fireplace cavity by
placing plastic control shaft forward through
round hole (see Figure 26, page 18).
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 mounting plate. Place
control knob provided on shaft (see Figure
26, page 18).
7. Check to make sure power cord is com-
pletely clear of blower wheel and that no
other foreign objects are in blower wheel.
Also double check all wire leads and make
sure wire routing is not pinched or in a
precarious position. Correct accordingly.
8. Turn on power to duplex outlet if previ-
ously turned off per warning in column 1,
page 18.
9. Plug in blower power cord to duplex outlet.
10. Blower will only run when speed control
knob is in ON position and thermal switch
senses temperature after fireplace begins
to heat up. Blower speed can be adjusted
by rotating control knob. To turn off, turn
knob fully counterclockwise until it clicks off.
If blower is ON and has been running with
fireplace operating, blower will continue to
run for a short time after fireplace has been
turned off. As thermal switch cools down,
blower shuts down automatically.
