1.6 BLOWER WIRING

These heaters have a factory installed fan, elec-
trical junction boxes, variable speed rheostat
control switch and temperature sensor switch
for the fan. These components are located be-
hind the lower grille. Use of the fan requires
that the junction box (factory installed) be con-
nected to 240 VAC service before permanently
enclosing the heater. The access hole for con-
necting the service wires is found on the lower
exterior side of the unit. Figure 32 shows the
fan, switches, and fan wiring diagram. Figure 33
shows the wire connection detail.
