1.6 BLOWER WIRING
These heaters have a factory installed fan, electrical junc-
tion boxes, variable speed rheostat control switch and tem-
perature sensor switch for the fan. These components are
located behind the lower grille.
Use of the fan requires that the junction box (factory in-
stalled) be connected to 240 VAC service before perma-
nently enclosing the heater. The access hole for connect-
ing 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.
