tional details.
Figure 3: Horizontal Configuration
2.3.4 Suspended installation
The furnace can be hanged to the ceiling in either up-
flow, downflow or horizontal. Make sure to mount it ap-
propriately 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, bod-
ily injury and/or property damage.
2.4 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 2 service wires of 120/240 - 208 volts.
WARNING
RISK OF FIRE
The conductor sizing must conform to the last edi-
tion of the local or national codes.
Failure to follow this rule can result in death, bod-
ily injury and/or property damage.
Power supply to the unit can be done using cop-
per 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 alu-
minum 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 replace-
ment, these must be copper wires only with same tem-
perature rating and sizes as originals.
2.4.1 Conversion from two wires to one
wire supply for models 25kW and
more
WARNING
RISK OF FIRE
When using one terminal block on models of 25kW
and higher, the installation must be performed
with copper wire ONLY in order to comply with the
Canadian electrical code. The usage of an alu-
minum 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 electrical diagram Figure 16.
Figure 4: Conversion from two to one supply wires
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, fire-
places, 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 in-
dicated on Figure 5 to Figure 9. 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 sup-
plied. This is to ensure that the heating mode is comfort-
able 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, render-
ing it ineffective.
2. Remove the wire from the W1 terminal of the fur-
nace and connect an ammeter between the termi-
nal and the wire.
3. Call for heat by raising the set point on the thermo-
stat 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
2.5.2 Air ducts
The ducts must be sized such a way as to accommodate
the specified airflow and the available static pressure.
5

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:
1. Use two elbows between each outlet and the sup-
ply and return air plenum;
2. Cover the vertical sections of the supply and return
air duct with soundproofing material;
3. Use baffles in short radius elbows;
4. Use flexible hangers to suspend the ducts.
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 fur-
nace. Refrigerant and drainage pipes must in no way
hinder access to the furnace panels.
2.6 SUPPLY AIR ADJUSTMENTS
Fan Control Board taps are used by the installer to con-
figure a system. The ECM motor uses the selected taps
to modify its operation to a pre-programmed table of air-
flows (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 such as
dehumidification request.
SUP electric furnace must be configured to operate prop-
erly with system components with which it is installed. To
successfully configure a system (see information printed
on circuit board label located next to select pins), move
the 6 select wires to the pins which match the compo-
nents used. (Refer to Figure 10)
Figure 10: Fan control board
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). Refer to the unit wiring diagram and
select the pin for the kW size heater being used (Refer to
Figure 10 and Figure 16).
The airflow must be large enough for safe and continu-
ous operation. (Refer to Table 3 and 4 for airflow delivery
CFM).
2.6.2 AC/HP size
Select System Size Installed
The factory setting for air conditioner or heat pump size
is the largest outdoor unit that can be used with the fur-
nace. Installer needs to select air conditioner or heat
pump size to ensure that airflow delivered falls within
proper range for the size unit installed.
The select pins are marked 3, 2 ½, 2, 1 ½ for furnace
equipped with ½ HP ECM motor and 5, 4, 3 ½, 3 for
furnace equipped with 1.0 HP ECM motor. Refer to the
unit wiring diagram and select the pin for the outdoor unit
size being used (Refer to Figure 10 and Figure 16).
2.6.3 System type
Select System Type Installed AC or HP
The type of system must be selected:
6

1. AC – Air Conditioner provides approximately 400
CFM per ton for greater efficiency and humidity
control with the AC/HP CFM ADJUST set to the
nominal (NOM) tap. To achieve more or less than
400 CFM per ton, move tap to (HI) or (LO) position
respectively. Refer to appropriate airflow tables for
exact CFM setting.
2. HP-COMFORT – Heat Pump Comfort provides ap-
proximately 350 CFM per ton for higher than normal
heating air delivery temperature.
3. HP-EFF – Heat Pump Efficiency provides same
airflow for heating and cooling modes to increase
overall HP efficiency; approximately 400 CFM per
ton with the AC/HP CFM ADJUST set to the nomi-
nal (NOM) tap.
The factory setting is AC (Refer to Figure 10 and Figure
16).
2.6.4 AC/HP CFM adjust
Select Medium, Low, or High Airflow
To provide airflow at rates described above, the AC/HP
ADJUST select is factory set to the nominal (NOM) tap.
The adjust selections HI/LO will regulate airflow supplied
for all operational modes.
HI provides 10% airflow over nominal unit size selected
and LO provides 10% airflow below nominal unit size se-
lected.
Setting options are provided to adjust airflow supplied
to meet individual installation needs for such things as
noise, comfort, and humidity removal. (Refer to Figure
10 and Figure 16).
2.6.5 ON/OFF delay
Select desired time delay profile
NOTE: Delay selections are active in cooling and heat
pump heating modes only. Electric heating modes have
a one (1) minute OFF delay at 50% airflow and zero (0)
ON delay programmed into the ECM motor that cannot
be overridden.
Four (4) motor operation delay profiles are pro-
vided to customize and enhance system operation. (Re-
fer to Figure 10 and Figure 16).
Selection options are:
1. 0/90: No ON delay and 90 second OFF delay at
100% airflow (factory setting).
2. 30/90: 30 second ON delay with no airflow and 90
second OFF delay at 100% airflow profile. Used
when it is desirable to allow system coils time to
heat-up/cool-down in conjunction with the airflow.
3. 0/0: No delay option. Used for servicing unit or
when a thermostat is utilized to perform delay func-
tions.
4. ENH: enhanced selection provides a 30 second ON
delay with no airflow followed by 150 seconds at
70% airflow, and no OFF delay for added comfort.
This profile will minimize cold blow in heat pump
operation and could enhance system efficiency.
2.6.6 Continuous fan
NOTE: If installed with a two-stage outdoor unit, do not
select HI speed continuous fan. If HI is selected, low
stage compression will also run HI fan speed possibly
resulting in insufficient dehumidification.
Select desired fan speed when thermostat is
set on continuous fan. (Refer to Figure 10 and Figure
16)
1. LO speed – factory setting, 50% cooling mode air-
flow.
2. MED speed – move connector to MED, 80% cool-
ing mode airflow.
3. HI speed – move connector to HI, 100% cooling
mode airflow.
2.6.7 Low-voltage circuit
Fusing and Reference
The low-voltage circuit is fused by a board-mounted 5-
amp automotive fuse placed in series with the trans-
former SEC2 and the R circuit. The C circuit of the
transformer is referenced to chassis ground through a
printed circuit run at SEC1 connected to metal standoff
marked with ground symbol.

2.7 INSTALLATION OF
ACCESSORIES
WARNING
ELECTRICAL SHOCK HAZARD
Turn OFF electrical power at the fuse box or ser-
vice panel before making any electrical connec-
tion and ensure that a proper ground connection
is made before connecting line voltage.
Failure to do so can result in death or bodily injury.
2.7.1 Humidifier and humidistat
connection
Fan Control Board terminals HUM1 (directly connected
internally to C on terminal block) and HUM2 (directly con-
nected internally to G on terminal block) are provided for
direct connections to the low-voltage control of a humidi-
fier through a standard humidistat (refer to Figure 11).
Figure 11: Standard humidistat connections
These terminals are energized with 24 VAC when
G thermostat signal is present. Alternately, the 24 VAC
signal may be sourced from the W1 and C terminal block
connections when electric heaters are used as a primary
heating source (refer to Figure 12).
Figure 12: Thermostat connections
2.7.2 Electronic Air Cleaner (EAC)
connections
Fan Control Board terminals AUX1 (directly connected
internally to C on terminal block) and AUX2 (directly con-
nected internally to G on terminal block) are provided for
direct connections to the low-voltage control of an elec-
tronic air cleaner. These terminals are energized with 24
VAC when G thermostat signal is present (refer to Figure
13).
Figure 13: Electronic air cleaner connections
2.7.3 Dehumidify capability with standard
humidistat connection
Latent capacities for systems using this unit are bet-
ter than average systems. If increased latent capacity is
an application requirement, the field wiring terminal block
provides a connection terminal (DH) for use of a standard
humidistat. The furnace control will detect the humidistat
contact opening on increasing humidity and reduce its
airflow to approximately 80% of nominal cooling mode
airflow. This reduction will increase the system latent
capacity until the humidity falls to a level which causes
the humidistat contact to close its contacts.
When the contact closes again, the airflows comes back
to 100% of the cooling airflow selected.
2.7.4 Use of a heat pump
When using a heat pump, a thermostat with dual fuel
option or a fossil fuel kit is required that prevents the op-
eration of the electric elements and the heat pump at the
same time. Refer to the instructions provided with the
thermostat or the “Fossil Fuel” kit for the proper wiring of
the furnace and the heat pump.
The simultaneous operation of the electric elements and
the heat pump will cause overheating of either unit. The
safety controls of the appliances will shut down the el-
ements or heat pump, since they are not designed to
function in this fashion.
3 OPERATION
3.1 START-UP
Before starting up the unit, be sure to check that the fol-
lowing items are in compliance:
1. The electrical installation and ventilation are con-
form;
2. The blower access door is in place and the blower
rail locking screws are well tightened;
3. The blower speed adjustments for heating and air
conditioning are appropriate and in accordance
with to the specifications in this manual;
4. The thermostat of the room is in heating mode and
is set higher than the ambient temperature;
5. The breakers on front panel are set on the “ON”
position.
To start the unit, turn the main electrical switch on.
3.2 USE OF MANUAL FURNACE
CONTROLS ON ADVANTAGE
FURNACE
When there is a demand for heat, the pilot light (L-1)
comes on. Refer to the wiring diagram.
When the “HI/LO” switch is put into the “LO” position, it
will shut down approximately half the elements.
However, it is important to put the switch back to the
8

“HI” position during the winter months to ensure ad-
equate heating.
Also, this switch must remain in the “HI” position when a
2-stage or outdoor thermostat is used to control the elec-
tric elements of the second stage. Refer to the diagram in
Section 2.5. The “ON/OFF VENT/FAN” switch engages
the blower in the continuous low speed mode. This will
filter the air and provide for better air distribution in the
building.
The 15 A circuit breaker is there to protect the motor and
the control circuit conductors. If the unit does not func-
tion, press the circuit breaker button to see if it may have
disengaged due to a power surge. If the breaker has to
be pressed again, the unit must be checked by a qualified
service technician.

3.3 OPERATING SEQUENCE
This unit is designed to provide the required airflow in
order to match with any of four (4) different electronic
heat capacity, air conditioner or heat pump outdoor unit
sizes (see Tables 3 and 4 for CFM values).
Also, the blower motor is a true variable speed motor
designed to deliver constant CFM. Constant CFM is valid
for systems with total external static pressure between
0.1 and 0.8 inches water column.
Refer also to Table 1 for sequence of operation summary,
depending on thermostat inputs and types.
3.3.1 Continuous fan
a. Thermostat closes circuit R to G.
b. Blower runs at continuous fan airflow.
3.3.2 Cooling mode - single stage
NOTE: For single stage systems, do not use the Y1 ter-
minal.
a. If indoor temperature is above temperature set
point and humidity is below humidity set point, ther-
mostat closes circuits R to G, R to Y/Y2 and R to
O.
b. Furnace delivers single stage cooling airflow.
3.3.3 Cooling mode - two stage
•First stage (low) cooling: Thermostat closes cir-
cuits R to G, R to O, and R to Y1.
Furnace delivers low stage cooling airflow.
•Second stage (high) cooling: Thermostat closes
circuits R to G, R to O, R to Y1 and R to Y/Y2.
Furnace delivers high stage cooling airflow.
3.3.4 Cooling mode – dehumidification
NOTE: Remove jumper « J1 » on board to activate this
function. (Refer to Figure 10 and Figure 16)
a. If indoor temperature is above temperature set
point and humidity is above humidity set point, ther-
mostat closes circuits R to G, R to Y/Y2 and R to O
and humidistat opens circuit R to DH.
b. The furnace delivers airflow which is approximately
80% of the nominal cooling airflow to increase the
latent capacity of the system.
3.3.5 Electric heating mode - modulating
thermostat
The thermostat sends a heating demand in the form of a
pulse width modulated wave that varies between 5 and
100%. The heating unit will apply this power ratio to the
maximum available power. The electrical elements will
modulate to the required power and the fan will adjust
itself automatically in order to reach the required temper-
ature rise.
3.3.6 Electric heating mode -
Communicating thermostat
The thermostst sends a heating demand from 5 to 100%
using a communicating protocol. The heating unit will ap-
ply this power ratio to the maximum available power. The
electrical elements will modulate to the required power
and the fan will adjust itself automatically in order to reach
the required temperature rise.
3.3.7 Heat pump heating mode –
Modlating thermostat outdoor unit
single stage
NOTE: For single stage systems, do not use the Y1
terminal.
a. Thermostat closes circuits R to G and R to Y/Y2.
b. Furnace delivers selected heat pump heating air-
flow.

3.3.8 Heat pump heating mode –
Modulating thermostat, outdoor unit
two stage
• First stage (low) heating: Thermostat closes cir-
cuits R to G and R to Y1.
Furnace delivers low stage heating airflow.
• Second stage (high) heating: Thermostat closes R
to G, R to Y1 and R to Y/Y2. Furnace delivers high
stage heating airflow.
WARNING
ELECTRICAL SHOCK OR UNIT DAMAGE HAZARD
Failure to carefully read and follow this WARNING
could result in equipment malfunction, property
damage, personal injury and/or death.
Disconnect power to unit before removing or re-
placing connectors or servicing motor. Wait at
least five (5) minutes after disconnecting power
before handling.
3.4 AIRFLOW VERIFICATION
Verify the airflow by taking readings of the following
points, while the elements are in heating mode:
a) Total amperage of all the heating elements;
b) Voltage at the furnace;
c) Supply air temperature. The point of the reading
must not be affected by radiant heat from the ele-
ments;
d) Return air temperature.
From these readings, one can arrive at an approximate
calculation of the average airflow. To do that, the follow-
ing formula should be used:
Liter/s =0.82 ×amps. ×volts
Diff. temperature °C
CFM =3.1×amps. ×volts
Diff. temperature °F
Tables 3 and 4 show estimated airflows for various
temperature rises.
3.4.1 Supply Air Temperature Rise Test
1. Operate the unit at maximum power for at least 10
minutes;
2. Measure the air temperature in the return air
plenum;
3. Measure the air temperature in the largest trunk
coming off the supply air plenum, just outside the
range of radiant heat from the heat exchanger. 0.3
m (12”) from the plenum of the main take-off is usu-
ally sufficient;
4. Calculate the temperature rise by subtracting the
return air temperature from the supply air tempera-
ture.
If the temperature rise exceeds the temperature spec-
ified in Table 2 by 5°F/2.8°C, move the “AC/HP
CFM ADJUST” black wire to high (HI) position.
If the excessive temperature rise cannot be re-
duced by increasing fan speed, investigate for duct-
work obstructions or dirty and improper air filter.
CAUTION
It is important to check the airflow and to ascer-
tain that the unit does not operate above the tem-
peratures specified in the Technical Specifications
(Table 2). This is particularly important if a cool-
ing coil or a heat pump has been installed in the
ducts.
Hi-Limit thermal protectors should never need to
engage during the normal functioning of the appli-
ance. They are strictly designed to engage during
the improper functioning of the blower or when the
filter was improperly maintained.
3.4.2 High limit verification
After operating the furnace for at least 15 minutes, restrict
the return air supply by blocking the filters or the return air
register and allow the furnace to shut off on High Limit.
The electric heaters must deactivate themselves before
the warm air temperature exceeds 200°F (93°C).
Remove the obstruction and the elements should restart
after a few minutes.
4 MAINTENANCE
WARNING
ELECTRICAL SHOCK HAZARD
Turn OFF power to the furnace before any disas-
sembly or servicing.
Failure to do so can result in death, bodily injury
and/or property damage.
Preventive maintenance is the best way to avoid unnec-
essary expense and inconvenience. Have your heating
system inspected by a qualified service technician once
a year. Do not attempt to repair the furnace or its con-
trols. Call a qualified service technician.
Before calling for repair service, check the following
points:
1. Check fuses or the circuit breakers;
2. Check if the 15 A circuit breaker on the furnace is
disengaged;
3. Check if the 5 A fuse of the control board is blown;
10

4. Set the thermostat higher than room temperature.
If the unit does not start up, cut the power and call
a qualified service technician.
When calling for service or ordering a replacement part,
specify the model and serial number of your appliance.
4.1 AIR FILTER
The disposable filter should be replaced twice a year.
The presence of animal hair, dust, etc. may necessitate
more frequent changes. Dirty filters have an adverse ef-
fect on the performance of the central heating system.
4.2 MOTOR LUBRICATION
Do not lubricate the blower motor, since it is permanently
lubricated.
