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 the 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.
2.5- 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 thermostats need to connect the C terminal
on the furnace and thermostat. Install the thermostat on an
interior wall in a location where it will not be subject to direct
sunlight, lamps, air diffusers, fireplaces, etc. Seal openings in
walls to avoid air currents that may 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 Figure 5 to Figure 9. Refer to the electrical diagram
(Figure 16
).
Figure 5: 1-stage thermostat, electric heating only
2.4.1- Conversion from two to one supply wires for
model over 27kW
Warning – When using one terminal block on models over
27kW, the installation must be performed with copper wire
ONLY in order to comply with the Canadian electrical code. The
usage of an aluminum or copper wire is acceptable on models
25kW and lower.
Move all wires from the two pole terminal to the three pole
terminal following the corresponding colors as shown in Figure
4.
The breaker and the supply conductors must be sized by adding
the ampacities of the two terminals indicated on the nameplate.
Refer to the electrical diagram Figure 16.

2.5.1- Anticipator adjustment (if required) on thermostat
equipped with heat anticipator adjustment
Some 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. If longer heating
cycles are desired, the anticipator can be set to a higher
value
b. Cover the vertical sections of the supply and return air duct
with soundproofing material;
c. Use baffles in short radius elbows;
d. Use flexible hangers to suspend the ducts.
The S
UPREME
blower compartment. It must be installed on the outside of one
of the three sides or the bottom of the furnace. Once the location
of the installation has been determined, use the four square
knockouts for ease of cutting the opening.
A heat pump or an air conditioner can be added to this furnace,
in either the supply or return air duct. Carefully follow the
instructions provided with these appliances to ensure proper
installation and hook-up to the electric furnace. Refrigerant and
drainage pipes must in no way hinder access to the furnace
panels.
furnace is equipped with a filter frame for the
2.6- SUPPLY AIR ADJUSTMENTS
Fan Control Board taps are used by the installer to configure a
system. The ECM motor uses the selected taps to modify its
operation to a pre-programmed table of airflows (Refer to Table
3 and Table 4). Airflows are based on system size or mode of
operation and those airflows are modified in response to
thermostat inputs.
SUP electric furnace must be configured to operate properly with
system components with which it is installed. To successfully
configure a basic system (see information printed on circuit
board label located next to select pins), move the 6 select wires
to the pins which match the components used. (Refer to Figure
10 below)
Figure 10 : Fan Control Board
2.5.2- Ducts and filters
The ducts must be sized such a way as to accommodate the
specified airflow and the available static pressure. Refer to the
applicable local and/or national installation codes.
Insulate the ducts that lead through non-heated areas. Use
flexible supply and return air connectors to avoid the
transmission of vibration. To make the unit run even quieter, the
installer should:
a. Use two elbows between each outlet and the supply and
return air plenum;
2.6.1- HEAT KW/CFM adjustment
Installer must verify (factory set) the electric heat airflow
adjustment required for kW size heater installed.
The select pins are marked 25, 23/20, 18/15, 10 (for ½ HP ECM
motor unit) and 30/27, 25, 23, 20, (for 1.0 HP ECM motor unit).
