a. With the Front Grill and Vent removed feed the wires inside the front assembly through the opening on the right
side shown in Figure 20. Use the supplied screw mount wire ties to secure wires at circled screws.
b. The orange wires will be wired inline with the High Limit Switch located at the back of the hopper. Disconnect
one of the orange wires already attached to the High Limit, now attach one of the orange wires from the HDK to
the wire you just disconnected. The other orange wire from the HDK will connect to the High Limit Switch.
c. The red wires form the HDK will have no connectors and will wired to the Thermostat connection on the back
side of the circuit board. The circuit board will need to be detached from the frame, a small fl at head screw
driver will be required to connect wires, see Figure 21.
d. There will be a purple wire coming form the circuit board that is connected to a black wire coming from the fan
at the rear of the unit. Disconnect these wires and connect the purple wire from the HDK to both, they will only
connect one way.
e. Locate where the power cord enters the unit at the back see Figure 23. Disconnect the black wire going to the
power cord connection. The Black wire from the HDK will connect to the disconnected wire and the power cord
connection.
