2100 SERIES BLOWER REPLACEMENT
NOTE: When replacing a blower in a 2100 Series heater, it is
important to make sure the blower resistor is correct for the
application. Read and follow instructions carefully to ensure
proper installation and operation.
1. Disconnect power to all branch circuits of the heater.
2. Remove painted front panel by removing the screws
located on the bottom edge of the painted front panel.
3. Hinge the right side panel open by a) removing the
screw located above grill slats on the lower right side of
the heater; b) loosening the screw located at top right
corner of the electrical compartment; and c) pushing out
on the right side panel. Reference Figure 1.
4. At the base I/O relay board (Figure 2) in the back of the
heater, disconnect the black wire from the "Blower" terminal.
5. Disconnect the white blower wire from the white/blue jumper
wire attached to L2 120 or L2 240 (depending on the
application).
6. Disconnect the green ground wire
from the back, right side of the
electrical compartment.
7. Remove the screw holding the
blower in place (Figure 3) and
remove the existing blower.
8. Inspect and clean blower opening
and damper actuator.
9. Insert the new blower and secure
into place with the screw (Figure 3).
10. Reconnect the green ground wire.
11. Connect the black blower wire to
the "Blower" terminal on the base I/O relay board. Connect the
white blower wire to white/blue jumper.
