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 front panel. Place control knob pro- vided on shaft.

7.Turn on power to duplex outlet if previously turned off per the warningon page 19.

8.Plug in blower power cord.

a.If your firebox is installed as a free- standing unit with an accessory mantel, determine whether the power cord will exit the left side or the right side of the firebox. Route power cord through exit hole and plug the power cord into a wall receptacle near the firebox.

b.If your firebox installation is recessed and/or prewired, plug the power cord into the duplex outlet provided. Refer to your firebox owner’s manual for instructions on wiring the duplex outlet.

Figure 30 - Blower Model BKT CAUTION: Never touch the blower wheel while in operation.

9.Check to make sure that the power cord is com- pletely clear of the blower wheel and that there are no other foreign objects in blower wheel. Turn blower on and check for operation. Turn blower off by turning knob fully counterclock- wise before continuing.

10.Peel off the backing paper and stick the sup- plied wiring diagram decal on the firebox bot- tom approximately 12" in front of the blower (see Figure 29).

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 30).

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.
