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 terminal
between the bottom hole on the thermal switch
bracket and the top ear hole on the blower as
-
sembly. Insert the phillips screw into all three
pieces and tighten securely (see Figure 29).
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.
3. Place the blower against the lower rear wall of
the firebox outer wrapper with the exhaust port
directed upward and the thermodisc positioned
up near the fireplace bottom. The thermodisc
must be oriented near the fireplace bottom as
shown in Figure 29 in order to sense tempera
-
ture and properly operate. The blower will be
held in position against the back wall by the
magnets incorporated onto the blower housing
(see Figure 29).
4. Be certain that all wire terminals are securely at
-
tached to terminals on blower motor and thermal
switch and that the screw for the thermodisc
bracket and green ground wire is tight.
5. Mount the speed control box against the
mounting plate provided in the lower fireplace
cavity by placing the plastic control shaft
forward through the round hole (see Figure
27, page 19).
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 27, page 19).
