Downflow installation
The return duct may be installed to the back, on the left
side, on the right side or under the unit. The supply duct
shall be installed on the top of the unit.
When the furnace is installed in the downflow position on
a combustible floor, the downflow base DFB-SUP can be
used. Refer to Figure 2 and the installation instructions
provided with the base.

2.3.3
Horizontal installation
The return duct may be installed to the back, on the left
side, on the right side or under the unit. The supply duct
shall be installed on the top of the unit.
When the furnace is installed in the horizontal position,
either suspended or on a combustible floor with a choice
of right or left discharge, the clearances from combustible
material must be adhered to.
Refer to Figure 3 for
additional details.

2.3.4
Suspended installation
The furnace can be hanged to the ceiling in either
upflow, downflow or horizontal.
Make sure to mount
it appropriately and to respect the clearances to
combustible material.
WARNING
The furnace must be properly secured especially
when installed above living space.
Failure to follow this rule can result in death,
bodily injury and/or property damage.

ELECTRICAL SYSTEM
The S
UPREME
furnace is completely pre-wired and all
field wiring must be connected to the terminal blocks on
the unit. It requires 2 service wires of 240 - 208 volts.
All the 120V models (SUPxx-y120Dzz) require neutral
wire because the motor works under 120VAC.
WARNING
R
ISK OF FIRE
The conductor sizing must conform to the last
edition of the local or national codes.
Failure to follow this rule can result in death,
bodily injury and/or property damage.
Power supply to the unit can be done using copper
or aluminum wires. The wire size must be decided in
accordance to unit power consumption, the over current
protection type and capacity, the wire type and length,
and the environment where the unit is installed. If an
aluminum wire is used, other precautions must be taken
to insure the conformity of the installation. In all cases, all
the factors affecting the wire gauge must be considered
and the installation codes followed.
The exterior of the unit must have an uninterrupted
ground to minimize the risk of bodily harm. A ground
terminal is supplied with the control box for that purpose.
A connector is supplied on the ground terminal to ground
an added accessory.
In
the
event
that
wires
inside
the
unit
require
replacement, these must be copper wires only with same
temperature rating and sizes as originals.
2.4.1
Conversion from two wires to one
wire supply for models 25kW and
more
Only for single-phase models.
