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 120/240 volt, 3-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  made  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. 

In the event that wires inside the unit require replacement, these 
must be as same type as originals.  

COPPER WIRING ONLY. 

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.    Install  the  thermostat  on  an  interior  wall  in  a 
location where it will not be subject to direct sun light, 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 the following diagrams and the wiring diagrams, p.12 and 16. 

1-stage thermostat, electric heating only 

2-stage thermostat, electric heating only 

1-stage thermostat with outdoor control for 2-stage 

function, electric heating only 

2-stage thermostat, electric heating and air conditioning 

2.5.1.

Thermostat heat anticipator adjustment (if 
required) 

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.
