Horizontal installation

The return duct may be installed to the back, on the left side,
on the right side or under 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.

ELECTRICAL SYSTEM

The SUPREME furnace is completely pre-wired and all field
wiring must be connected to the terminal blocks on the unit.
It requires a 240 volt, 2-wire power supply.
WARNING
Risk 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.
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 as originals.

INSTALLATION OF THE THERMOSTAT

A thermostat must be installed to control the temperature of
the area to be heated. Follow the instructions supplied with
the thermostat. Some thermostat need to connect the C
terminal on the furnace and thermostat.

influence the operation of the thermostat. Also refer to the
wiring diagrams provided with the heating/air conditioning
unit. The connections must be made as indicated on
Figures 4 to 8 diagrams and on electrical diagrams (Figures
10 to 14).
2.5.1. Anticipator adjustment (if required) on
thermostat equipped with heat anticipator
adjustment
Certain thermostats are equipped with a heat anticipator that
must be adjusted according to the instructions supplied.
This is to ensure that the heating mode is comfortable and
economical.
Generally speaking, on a single stage thermostat, a reading
of the current must be taken with an ammeter as follows:
1. Move the anticipator to its highest setting, rendering it
ineffective.
2. Remove the wire from the "W1" terminal and connect an
ammeter between the terminal and the wire.
3. Call for heat by raising the set point on the thermostat
and allow the furnace to run for 3 to 4 minutes to reach
its peak output.
4. Once the current has stabilized, a reading should be
taken and the anticipator adjusted to that value.
longer heating cycles are desired, the anticipator can be
set to a higher value
