through the observation window in the blower access door.
Refer to the Diagnostic Signal Chart for further explanation
of the lighting codes and Section X, Start-Up, Adjustments,
and Checks, Abnormal Operation - Integrated Ignition
Control for an explanation of the possible problem.
On new installations, or if a functional part such as the gas
valve, pressure switch, or limit control has been replaced,
verify that the furnace is operating properly after servicing.
Check furnace operation as outlined in the following in-
structions. If any sparking, odors, or unusual noises are
encountered, shut off electrical power and recheck for
wiring errors, or obstructions in or near the blower motors.
Various shipping materials must be removed before the
blower motor is operated.
ROLLOUT PROTECTION DEVICE
If the flames from the burners are not properly drawn into
the heat exchanger, a protection device will open causing
the gas valve to close. In GUI(-) furnaces installed horizon-
tal right-to-left airflow, the device must be relocated.

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 29 and 30. 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.)
3. As shipped, the rollout protection device is located near
the flame sensor end of the manifold assembly. Re-
move and save the mounting screws.
4. For most installations, it will not be necessary to remove
the wires from the rollout protection device.
5. For horizontal-left installations, a hole is provided near
the igniter end of the manifold assembly. Insert the
rollout protection device into this hole and attach with
screws removed in step 3.
6. Secure rollout wires to manifold and insure no wires can
come in contact with burners or other hot surfaces.
7. Push the button to confirm the rollout control is in the
closed position.
8. Replace the cover on the burner box, replacing the
screws from step 2.
WARNING
To prevent death, personal injury or
property damage due to fire or explosion,
a qualified servicer must determine the
reason the rollout protection device opened
before the device is reset.
