Model BKT Installation
Note: When installing the BKT
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).
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.
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 28 in order to sense temperature and properly operate. The blower will be held in position against the back wall by the magnets incorpo- rated onto the blower housing (see Figure 28).
4.Be certain that all wire terminals are securely attached to ter- minals 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 pro- vided in the lower fireplace cavity by placing the plastic control shaft forward through the round hole (see Figure 26).
6.While supporting speed control, secure control shaft with lock nut by pushing and turning lock nut with pliers clockwise un- til it is tight against mounting plate. Place control knob pro- vided on shaft (see Figure 26).
7.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. 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 the warning in column 1, page 16.
9.Plug in blower power cord to duplex outlet.
10.The blower will only run when the speed control knob is in the ON position and the thermal switch senses temperature after the fireplace begins to heat up. The blower speed can be ad- justed by rotating the control knob. To turn off, turn knob fully counterclockwise until it clicks off. If the blower is ON and has been running with the fireplace operating, the blower will continue to run for a short time after the fireplace has been turned off. As the thermal switch cools down, the blower shuts down automatically.
11.Peel off the backing paper and stick the supplied wiring dia- gram decal on the firebox bottom approximately 12" in front of the blower (see Figure 27).
