3.Place the blower against the lower rear wall of the firebox outer wrapper with the exhaust port directed upward. The blower will fit inside the back opening and be held in position against the back wall by the magnets (see Figure 25, page 14).

4.Be certain that all wire terminals are securely attached to ter- minals on blower motor and that the screw retaining the green ground wire is tight.

5.Mount speed control box to switch bracket by placing the plastic control shaft forward through the opening in the switch bracket (see Figure 26).

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 provided on shaft.

7.Turn on power to duplex outlet if previously turned off per the warning in column 2, page 14.

8.Plug in blower power cord.

a.If your firebox is installed as a freestanding 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 pre-wired, plug the power cord into the duplex outlet provided. Refer to your firebox owner’s manual for instructions on wiring the duplex outlet.

CAUTION: Never touch the blower wheel while in operation.

9.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. Turn blower on and check for operation. Turn blower off by turning knob fully counterclockwise before continuing.

10.Peel off the backing paper and stick the supplied wiring diagram decal on the firebox bottom approximately 12" in front of the blower (see Figure 27).

Model BKT Installation

Note: When installing the BKT thermostatically-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 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 thermo- disc 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 incorporated onto the blower housing (see Figure 28).
