7. Flame Sensed with No Call for Heat
If the control senses a flame when the gas valve is
de-energized, the induced draft blower will run for 15
seconds then turn off and the air circulation blower
will run continuously. The diagnostic light code for
this is continuous flashing. Probable cause is
miswiring.
Normal Cooling Sequence - Integrated Ignition
Control
With the room thermostat in the FAN-AUTO position, the
indoor air circulation blower and outdoor condensing unit
will be energized when a call for cooling occurs. When
the call for cooling ends, the outdoor condensing unit will
be de-energized. The indoor air circulation blower will
continue to run for 45 seconds.
Other Items
Constant Fan. During normal operation, the air
circulation blower will continually run at "Cooling"
speed as long as power is present at terminal G. If a
call for heat occurs, the blower will run at heating
speed throughout the heating cycle.
If a trip on high/auxiliary/rollout limit occurs, the air
circulation blower will run at "Heating" speed. Even
if power is present at terminal G, the blower will run
at heating speed until the limit closes.
X. Start-Up and Adjustment
General Operation
This furnace is equipped with an electronic ignition device
to light the burners and an induced draft blower to draw
combustion air into the heat exchanger.
Keep the access doors in place except for inspection and
maintenance. An interlock switch prevents furnace oper-
ation if the blower door is not in place.
On new installations, or when a functional part (gas valve,
pressure switch, or limit control) has been replaced,
verify proper operation after servicing.
Check furnace operation as outlined in the following
instructions. If any sparking, odors, or unusual noises are
noted, shut off electrical power and check for wiring
errors, or obstructions in or near the blower motors.
Rollout Protection Device
IMPORTANT NOTE: This furnace is equipped with a
device to close the gas valve if the burner flames are not
drawn into the heat exchanger. In GUI(-) furnaces in-
stalled horizontal right-to-left airflow, the device must be
relocated.

Left To Right Installation
If relocation is required, proceed as follows:
1. Disconnect electrical power.
WARNING
To prevent death or personal injury due
to electric shock, disconnect electrical
power.
2. See Figures 33 & 34. Remove the cover from the
burner box. Save the screws that held it in place.
(Note: There are several screw holes, but only four
screws. This is intentional, and not a manufacturing
defect.)
