9. Check to make sure power cord is completely
clear of blower wheel and there are no other
foreign objects in blower wheel. Turn blower
on and check for operation. Turn blower off

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 be-
tween bottom hole on thermal switch bracket
and top ear hole on blower assembly. 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 up-
ward and thermodisc positioned up near fire-
place 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 completely
clear of blower wheel and that no other foreign
objects are in blower wheel. Also double
check all wire leads and make sure wire rout-
ing is not pinched or in a precarious position.
Correct accordingly.
8. Turn on power to duplex outlet if previously
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 tem-
perature 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.
