9. Wire the blower to a 115-volt, 15-amp breaker through the thermostat provided. The variable speed switch pro-
vided should be installed in a convenient location near the fireplace so the blower can be shut off during
refueling. The blower control center should be placed in an accessible location near the blower. It should be
mounted in a 4x4 electrician's box. You have two options of how you can connect the central heat blower to
the blower control assembly.
a) If you would like the blower to turn on when the thermostat calls for heat, first locate the thermostat in the
principal room heated by the duct system (this is the most popular use of the central heat blower). Do not install
it in the room where the fireplace is installed. There are yellow black and red wires coming out of the relay as
shown in the wiring diagram Connect the wire from #4 of the terminal block to the black wire and put the
marrette connector on the red wire for protection. (See Figures 37 and 38) for schematic wiring diagrams.
b) If the fireplace is in a small room and/or you would like the central heat blower to remove air from this room
when it becomes too hot, locate the thermostat in the room with the fireplace (this is a less common use of the
central heat blower). Connect the wire from #4 of the terminal block to the red wire and put the marrette
connector on the black wire for protection. (See Figures 37 and 38) for schematic wiring diagrams.
(Figure 29) shows some ways of ducting the hot air from the blower. You are not restricted in the size of pipe
as long as the total cross sectional area of all runs combined is not less than 50 square inches. The diagram
shows alternate blower locations. Only one external blower can be installed.
10. If the blower fails to operate, check the following:
a) Consult the wiring diagram to assure proper connections.
b) To assure proper contact, check the motor lead wiring, incoming supply wiring, and capacitor connections.
c) If possible, use a meter to test for continuity between the fan leads. Please note that the capacitor will show
no reading if it is tested with a meter.
