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. 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 wire connector on the red wire for protec-

tion. (See Figures 36 and 37 for schematic wiring dia-

grams.)

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 ther-

mostat in the room with the fireplace. Connect the

wire from #4 of the terminal block to the red wire and

put the wire connector on the black wire for protec-

tion. (See Figures 36 and 37 for schematic wiring dia-

grams.)

(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 com-

bined is not less than 50 square inches. The diagram

shows alternate blower locations. Only one external

blower can be installed.
