Model BKT Installation
Note: When installing the BKT thermostatically
1.Place green ground wire with ring ter- minal between 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 29).
2.Connect wire harness and power cord terminals. Connect blue jumper wire to blower motor terminal and right side termi- nal 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 connec- tions. DO NOT trim excessive length away. Enable just enough to make all connections securely.
3.Place blower against lower rear wall of firebox outer wrapper with exhaust port di- rected upward and thermodisc positioned up near fireplace bottom. Thermodisc must be oriented near fireplace bottom as shown in Figure 29 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 29).
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 mount- ing plate provided in lower fireplace cavity by placing plastic control shaft forward through 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 provided control knob on shaft (see Figure 27, page 19).
