START UP, ADJUSTEMENT
AND SAFETY CHECK
9.1
TO START FURNACE
• Furnace must have a 120 V power supply properly
connected and grounded (
NOTE
: Proper polarity
must be maintained for 120 V wiring. Control status
indicator light flashes rapidly and furnace does not
operate if polarity is incorrect.)
• If the modulating thermostat is used, thermostat
wire connections at terminals R, W/W1, G, Y/Y2,
etc. must be made at 24 V terminal block on fur-
nace control.
• Natural gas service pressure must not exceed 0.38
psig (10.5 in. w.c.), but must be no less than 0.16
psig (4.5-in. w.c.). Propane service pressure must
not exceed 0.47 psig (13 in. w.c.) but must be no
less than 0.40 psig (11 in. w.c.).
• Blower door must be in place to complete 120 V
electrical circuit to furnace.
• EAC-1 terminal is energized whenever blower op-
erates.
• HUM terminal is only energized when blower is en-
ergized in HEATING.
9.1.1
Lighting instruction
This appliance is equipped with a hot surface ignition de-
vice. This device lights the main burners each time the
room thermostat calls for heat.
During initial start-up, it is not unusual for odour or smoke
to come out of any room registers. To ensure proper ven-
tilation, it is recommended to open windows and doors
before initial firing.
The furnace has negative pressure switches that are a
safety during a call for heat. The induced draft blower
must pull a negative pressure on the heat exchanger
to close the negative pressure switch.
The induced
draft blower must maintain at least the negative pres-
sure switch set point for the furnace to operate. If the
induced draft blower fails to close or maintain the closing
of the negative pressure switch, an error code would re-
sult.
1. Set the room thermostat to its lowest setting and
turn of furnace electrical power.
2. Remove the burner compartment control access
door.
3.
IMPORTANT
: Be sure that the manual gas control
has been in the “OFF” position for at least five min-
utes. Do not attempt to manually light the main
burners.
4. Turn the gas control knob on the «on» position.
5. Replace de burner compartement control access
door.
WARNING
Failure to replace the burner door can cause
products of combustion to be released into
the conditioned area resulting in personal in-
jury or death
6. Turn on the manual gas control.
7. Turn on the furnace electrical power.
8. Put the thermostat to «Heat» mode and set the
room thermostat at least 10°F above room temper-
ature to light the main burners.
9. After the burners are lit, set the room thermostat to
the desired temperature.
9.2
UNIT OPERATION HAZARD
These furnaces are equipped with a manual reset limit
switch in burner assembly. This switch opens and shuts
off power to the gas valve if an overheat condition (flame
rollout) occurs in burner assembly. Correct inadequate
combustion-air supply or improper venting condition be-
fore resetting switch. DO NOT jumper this switch.
Before operating furnace, check flame rollout manual re-
set switch for continuity. If necessary, press the button to
reset switch.
9.3
SETUP SWITCHES
The furnace control has setup switches (dipswitches) that
may be set to meet the application requirements.
These
switches are ignored on communicating system (us-
ing the Alizé and the communicating T-stat).
To set these setup switches for the appropriate require-
ment:
1. Turn off electrical power.
2. Remove upper door.
3. Locate setup switches on furnace control.
4. Configure the set-up switches as necessary for the
application.
