Also note that the blower in the rear compartment can be removed by loosening the 4 wing nuts (figure 3) that hold it to
the blower supports. The wire is long enough so you can remove the blower from the unit without disconnecting it.
CAUTION: when removing the blower, DO NOT remove the blower legs. Loosen the 4 wing nuts and slide the blower
out. To replace the blower, position the studs in the slots on the blower legs and fully insert the blower. Be sure to
RETIGHTEN the wings nuts after reinstalling the blower. Consult figure 4 for details.

4.0 Electrical connection to the furnace
4.1 240VAC – High voltage
You only need to bring a 2 conductors wire + ground to the furnace for the series 100 and 200 and a 3
conductors wire + ground for the series 300. The only electrical "installation" to the furnace is this connection.
All other wiring is factory installed/connected. Consult the local electrical codes for the size of the conductors
needed between the distribution panel and the furnace and the grounding of the unit. The use of copper wires is
recommended. If aluminum wire is used, make sure to respect all applicable codes.
Alternate 240V
Wiring connection
4.2 24VAC – Low voltage (Thermostat and controls)
All 24VAC connections are done on the left portion of the upper front panel on the 8 positions magnum style
terminal (recessed and accessible by removing the 2 screws on the small access panel). The terminology used is
the standard HVAC terminology. Please refer to figure 6.

Also note that it is possible to change the
orientation of the main terminal block in the
furnace to accommodate a supply wire coming
from the left or right. The factory installed position
is on the right side. Knock‐outs are provided on the
left and right side panels. If you choose to reorient
the main supply block, you will have to disconnect
and reconnect the internal wires to the block. To
do this, consult the electrical diagrams in the
following pages. THIS CAN ONLY BE DONE BY A
QUALIFIED TECHNICIAN AND/OR ELECTRICIAN.
Fig.5 above shows the different possible
configurations.
